A growing number of colleges
and universities in Puerto Rico, the United States of America, and other
parts of the world are using the computer technology to strengthen their
classroom teaching-learning process. Various higher educational institutions
have developed high-technological electronic multimedia classrooms, and
computer-related faculty training programs. Potential future trends are
clear. Instructional computing is widely used for classroom multimedia
digital media presentations and for interactive computer-based
training (CBT). More and more educators had changed their approach toward
the computer-based instruction (CBI), particularly the authoring
of computerized teaching materials.
The construction of CBI
programs for higher education can be oriented toward four basic types of
approaches: 1) drill and practice applications, 2) instructional tutorial
programs, 3) simulation applications, and 4) educational games. Most educators
empower these possible areas for the development of CBI applications with
multimedia
elements.
Multimedia
represents the most recent technical development that had been incorporated
as an aid to the educational process and in the business world. The term
multimedia
refers to an organized multisensory delivery and access of information
by a variety of display media, namely, text, computer graphics (charts
and graphs), static images, moving images (video), animation, and audio
sound (music, voice), which are integrated into an authoring presentation
system manipulated by a microcomputer and its user. Multimedia
uses different computer peripherals (computer monitor and/or projecting
device, CD-ROM player, video disk player, VCR tape deck, scanners, audio
digitizer, and other devices) to deliver the ideas and information of a
computer-generated presentation graphics or interactive multimedia application.
A multimedia delivery system represents a combination of
hardware and software that incorporates multiple media resources (text,
graphics, animation, video, and music/voice) within a personal computer
(PC) system. Multimedia is known to be interactive, which
means that the student controls and manage non-sequentially the direction
of the information provided by the CBI multimedia program. That is, there
is a back-and-forth interaction between the participant and the multimedia
software. Special interactive tools are incorporated into
the multimedia CBI applications, namely, hypertext and hypermedia.
Hypertext
is a metaphor used in interactive CBI applications to create non-sequential
net-like dynamic links of hot spots textual materials (e.g.,
words, phrases, and chunks of information) for easy search and access of
an interactive computer-based information database. For example, clicking
on highlighted words or phrases would randomly access other references
(e.g., a definition of a concept), objects/images, or audio/video sequences
or events. Therefore, hypertext provides a powerful navigational
tool that enables the user to search and display automatically
linked text-based information (the source end of the link) from a rich
variety of cross-references (the destination of the link). Hypermedia
represents the non-textual multimedia interaction of cross-connected pieces
information (e.g., menu buttons) that allows the viewer to begin anywhere,
to move around within the application, and to search, scan, browse, and
retrieve interconnected modules (the basic unit of a CBI application) and
related multimedia elements, such as, text, video clips, animation files,
sound, and graphics. Therefore, hypermedia provides to the
students a non-linear navigation that enables the access
of information according to their particular interests. Hypermedia
and interactive multimedia are often used interchangeably.
The use of interactive multimedia
delivery systems at the higher education setting greatly enhances the teaching-learning
process. It is well known from the educational studies that we remember
about 20% of what we hear, 40% of what we see and hear, and about 75% of
what we see, hear and do. In addition, CBI programs provides an 10 to 20%
of learning improvement as compared to conventional teaching classes (Molnar,
1990, cited in Oblinger, 1992, p. 6). Multimedia CBI programs provides
to the student with a variety of media elements from which the student
can actively select for an wide range of interactive experience that enhances
the learning processs. This multimedia learning process allows the student
a natural self-paced access of the information, which leads to a better
understanding and to discover on their own. Interactive multimedia CBI
applications makes possible the integration of media into interactive programs
with the potential to expand the use of visualization at different professional
disciplines, such as education, health science, natural science, and other
academic areas. Hypermedia-based CBI applications supplies to the student
an essential tool for an quick access of information and media displays
that will facilitate the student's research skills, stimulates problem-solving
situations, improve their abilities to acquire depth of knowledge, and
encourage them to create their own interpretation from personal experiences.
A meta-analysis study performed by Cohen & Decanay (1992) found that
CBI programs can also improve the effectiveness of the teaching-learning
process in health professions education.
Computer delivered courses
in the form of online multimedia presentations of the lectures increases
the attention and interest of the students by providing specific and near-real
life examples multimedia elements. Higher education faculty members are
using multimedia presentation graphics systems to improve their teaching
and conference presentations, as well as in their proposals for research
grants.

WHY INTERACTIVE MULTIMEDIA CBI AND PRESENTATIONS AT HIGHER EDUCATION SETTINGS?
Interactive multimedia encourages
self-expression and discovery by means of its interactive non-linear access
of information. Students will be more motivated to learn, since an multimedia
lesson (in the form of a digital presentation lecture and/or interactive
multimedia computer instruction) can provide near-reality information through
its variety of available media elements (text, sound, animation, and video).
The students may learn by using their multiple senses (particularly sight,
and hearing), which provides new and enriched experiences. The learning
process will be an active one, leaving the students to learn by their own.
The lecture and/or interactive/individualized lesson will provide a stimulating
environment that can improve the learning proccess by enhancing understanding
and retention of the subject matter (Galbreath, 1994; Oblinger, 1992).
A summary of the pedagogical and cost-effective benefits
of interactive multimedia applications and lecture presentations at the
higher educational institutions are listed below (Jensen, 1991, cited in Oblinger, 1992, pp. 9-10; Lamb, 1992; Miller, 1990, cited in Lamb, 1992,
p. 37):
1. The self-paced and discovery features of interactive multimedia eventually will result in mastery and increased retention of the information. The use of multisensory channels offers to the students different visual and auditory cues, so that each one can match his/her sensory preferences and needs. Consequently, learning can be enhanced as well as motivation for further interactive multimedia experience. The role of the professor will change from one as a dispenser of information to a one as a facilitator for the educational process.
2. The interactivity nature of multimedia CBI programs assures an active and constructive educational process among the students, since the lecture presentation and or interactive software will be controlled by the students decisions and abilities. Therefore, the students will be more in control of their own learning.
3. Well-developed multimedia CBI applications will allow students to concentrate on the concepts being taught, study particular issues (simulate problems), and encourage problem-solving circumstances.
4. Real-life subjects matters can be incorporated in the multimedia lesson. Such feature provided by the multimedia lessons can supply to the student the capacity to access near-reality hazardous content matters without life-threatening risks.
5. Reinforcement by means of feedback is possible during an interactive multimedia CBI lesson. This encourage motivation and provides for a better understanding of the information.
6. The use of interactive multimedia among students reduce the time required for the learning process. Multimedia-based CBI applications will decrease the time needed by the students to master associated concepts.
7. In terms of cost-effective advantages, interactive multimedia reduce the cost per student for the development of educational material.
8. The delivery of instructional material are more consistent as compared with traditional lecture classes.
9. Interactive multimedia provides individualization and student privacy.
10. The teaching-learning process can also be improved at the higher education level when the professor use online multimedia capable presentation graphics for their class lectures. These multimedia presentations can increase the students attention to the class lecture and clarify complex concepts. Moreover, class discussion and analytical thinking can be stimulated when the professor expose the students with special issues and hidden facts employing the interactive multimedia tools. The professor can use these tools to fulfill the instructional objectives of the class lessons.
11. Higher educational teaching-learning
process can be significantly enhanced due to the nature
hypertext/hypermedia tools which can be incorporated in the multimedia
CBI application or
classroom presentation. For example, previous particular lecture notes/topics
can be easily
access, so that specific doubts and requested questions by the student
can be clarified.
Furthermore, information inserted a during a digital presentation lecture
can be recalled in
future presentations.
12. The content discussed during the lectures can easily be made available at the university computer networks or stand-alone computer stations. Such valuable campus service makes possible afterward reviews of the class lectures and can clarify unanswered questions of the class subject. Likewise, students that had miss one or more presentation lectures can latter view the topic discussed during the computer-generated presentation. Similarly, remedial lessons and test can be scheduled for those students with poor learning skills.
13. During the preparation of the multimedia materials, the professor will have to put more attention on the particular topic developing and to amplify his imaginative pedagogical skills for an effective delivery of the class presentation
14. Interactive CBI can assure an equally access of high-quality education.
15. Education and training cost will
be significantly reduced.

INTERACTIVE MULTIMEDIA CBI DEVELOPING PROCESS
Authoring multimedia. All types of developed instructional lessons and/or presentations have authors. The authors are engaged in the process of composing multimedia elements, incorporating media displays (still and moving images, sound bytes, and plain text), cross-references, and other pieces of information into an integrated hypermedia-based multimedia application (Fisher, 1994). Stated in another form, authoring for multimedia CBI programs and classroom presentation refers to the process by which the developer use an authoring system to create educational programs or on-line presentation designed to serve as an teaching tool. An authoring system represents the software package used to integrate various interactive/multimedia documents into a single multimedia CBI application and/or presentation (Fisher, 1994, p. 269). Commercially available multimedia authoring softwares must be the first choice for the novice professor when planning for the development of interactive multimedia CBI programs. Within the Windows operating system environment, those professors with more experience and some knowlege in programming, it is recommended to combine his multimedia project using an Window-based programming language, such as C and C++ (Perry, 1994, p. 15). The majority of Windows itself is written in C. Therefore, an effective multimedia application would rather be written with C or C++. The interactive programs created with these languages will benefit in terms of speed and execution than those applications generated solely by authoring softwares (Perry, 1994 p. 15). Normally, the authoring of multimedia is a team approach, requiring several different people, each with separate skills.
Suggested developmental CBI principles and steps. For any type of CBI multimedia application development process, the professor should follow specific design principles, so that the success of the final product can be assured. Cates (1992) had nicely developed fifteen basic principles. These principles are described below:
Poston (1993) had developed an easy to follow steps when creating interactive CBI applications. These steps consist of:
Planning the interactive multimedia application. Planning the development of an effective interactive multimedia softwares at the the higher education sphere requires a careful following of specific developmental stages/steps. The planning process consist of six general stages or steps (Alessi & Trollip, 1991, pp. 244-273; Fisher, 1994, pp. 223-227; Linderstrom, 1994 pp. 90-129; NRI Schools, 1993, pp. 1-26; Price, 1991, pp. 61-82; Wolfgram, 1994, pp. 139-151), namely: 1) analysis, 2) design, 3) logistics and production, 4) production of supporting material, 5) implementation, and 6) evaluation.
Analysis. This fase of development consist of two specific steps: 1) the goals analysis, and 2) the need analysis.
1) THE GOALS ANALYSIS.
It is essential that the professor is capable to determine the
purpose or general idea of what he hope to accomplish from the multimedia
project. In other
words, the professor should analyze and determine the overall goals for
the interactive
multimedia CBI proyect/lesson. Each lesson that comprises the CBI program
must include
particular goals. Goals are general/broad statements. The goal of the interactive
CBI lesson
involves what the student must know or be capable to perform after finishing
the CBI lesson.
Establishing the lesson goal implies the assessment of the specific characteristics
and
educational needs of the students. A good interactive multimedia CBI application
should
meet the needs of the students and curriculum. Therefore, the multimedia
CBI project must
be well-integrated into the academic curriculum of the college or university.
Once the general
purpose/goal of the multimedia project had been established, the professor
must now
determine the best approach required to accomplish such purpose. This can
be answered by
the results of the need analysis. Furthermore, the developer (i.e., the
professor) should
determine the content, and guidelines to be used. The professor must set
realistic limits of his
potential application according to the available resources (particularly
funding support
resources) and time.
2) THE NEED ANALYSIS. It is vital to the establish/assess interest and instructional needs the students (the target audience). This can be carry out by gathering information through brainstorming (generating ideas, solving problem and/or collecting data), observations (direct observation of the group of students involved during specific working class tasks), surveys (using questionaires), interview of experts or other faculty members related to the matter you teach, and literature review. According to Allessi and Trollip (1991), the need analysis of the intended students can be performed by determining the characteristics (such as, age and relevant skills), present competencies, limitations, and familiarization with the subject matter included in the CBI lesson of these students. After establishing the goals and objectives of the project, the professor must determine the best approach to meet these goals. During the need analysis, the professor should analyze the audience (students), determine the content and define the delivery system.
a) Analyzing the audience (audience analysis). After the professor had established his general goals, the next step is to identify any characteristics, attitudes, preferences, or expectations of the students. This will help develop the design of the CBI application, which is part of the process of defining the target audience. The professor should know their students, their level of knowledge of the subject matter, expected academic skills, and other characteristics. Defining detailed characteristic of your target students should include the following considerations: demographics (statistical characteristics of your students, such as age, gender, level of knowledge of the subject matter) attitudes (opinions and outlooks shared among the students) preferences (such as, special interests, and dislikes), experiences (such as knowledge level of the subject and computer experience), expectations (will the students expect that the CBI program should provide entertainment as well as an learning experience of the subject/lesson?).
b) Defining the content (content analysis). Once the professor have an complete perspective of the particular needs of the intended students, its time to determine more specifically what should be included in the subject matter of the proposed CBI lesson. From the goals, and need analysis, the content and concept will be developed. The content analysis will determine more specifically the subrrject/topic to be covered of your interactive multimedia CBI application or digital presentation lecture. The content of the multimedia presentation or CBI application defines specific information required to communicate the message (such as, facts, figures, and other data). The content analysis may consist of deciding on a storyline, researching and organizing references information, or outlining the rules of the game. The concept establish the manner in which the professor is going to present the content, so that the pre-established goals can be attained. The developer/professor should determine the limits/scope of the project. Such process will aid in the establishment of the type of application required for the multimedia project. Take time to determine the cost of the production based on the CBI lesson scope. Establish the media resources needed. The most important part of the content analysis is the base knowledge of the subject matter (rules, definitions, concepts, and physical skills/task). In order to develop the content of an educational application, the professor must first create instructional/learning objectives. Based on these objectives, the professor will be capable to create a general outline of the required topics to covered within the content of the CBI lesson. It is recommended to establish specific instructional/learning objectives for both the end of a lesson (general or terminal objectives) and intermediate points during the lesson (intermediate, specific or enabling objectives) (Allesi & Trollip, 1991; Price, 1991). One of the most important aspects to be considered during the content analysis is to adopt an systematic methodology todetermine the topics, content, and approaches used to develop the CAI application. For instance, the topics that should be included in the content of the CBI lesson can be established by means of several methods, such as brainstorming (to generate creative ideas), a preliminary research to gather information necessary to create the CBI program, and other tools. Once the professor had collected and evaluated the information for the lesson, the following step is to organize of it.
c) Determining the delivery system. After the completion of the above stages, the professor should analyze the delivery system, so that it he could determined the tools needed. The delivery system refers to multimedia computer-based player that the intended students will employ to view andinteract with the CBI lesson (Fisher, 1994, p. 9.). The When establishing the delivery system, the professor should consider the following factors: (1) physical environment (of the application), (2) the functional requirements, (3) the delivery media, (4) hardware needs, and (5) types application softwares required to develop the proposed CBI lesson.
The first step is to analyze the factors affecting the application's environment. Normally the professors can develop their CBI programs for the campus computer center or for the classroom presentation lectures. In such places, the professor must take in consideration those physical surroundings factors that can negatively affect the student learning process. Such physical entourages factors can be accessibility, distraction/noise, light, and temperature. All these factor will eventually determine the way the professor is going to design the application.
The CBI application developmental process will also be affected by certain functional features to be considered, such as, types of media to be used (e.g., sound, video, graphics, etc.), degree of complexity of the CBI application, special features required, types of hypertext/hypermedia tools to be incorporated, audio and video requirements, and so forth. The above information gathered must now be reviewed to determine the hardware and software requirements of the proposed CBI lesson.
Now is time to determine the way the professor is going to deliver his multimedia CBI application to is target students. For small applications, the professor may deliver his multimedia project on a floppy disk. Another option is to compress the application onto floppy disk for installation on a hard drive. For a larger multimedia project, the professor will require a high-capacity delivery medium such as CD-ROM or laserdisc. There is currently a great deal of interest at many educational settings for the development of multimedia interactive Compact Disks (CD). CBI delivery in the form of interactive multimedia training applications can be more effective if its information can be digitally stored in a CD-ROM. The CD-ROM can store up to 650 megabytes (MB) of data, including multimedia files (e.g., motion video, animation, and sound/music).
The available hardware that the university possess should be considered when deciding how to the deliver the multimedia application to your students. The Three types of hardware used for multimedia are the computer, peripherals, and add-on-boards. The multimedia computer setup requires a fast Central Processing Unit (CPU), such as an Pentium 90 or higher, a minimum of 16MB Random Access Memory (RAM) upgradable to 32MB or more. It is recommended a full tower computer case, builded with a PCI-motherbord system coupled with PCI slots (buses). The CBI lesson requiere basic/important peripherals. Peripherals are devices (such as, monitors, disk drives, printers, modems, and joysticks) that are connected to a computer but are physical separated. The computer monitor should have a minimum of 1024x768 resolution. At least a 64-bit PCI graphic card with 2MB (better with 4MB) of Video RAM (VRAM) and a 15-inch (better with a 17-inch or higher) monitor is required in order to run 24-bit 800x600 motion video and graphics without disconcerting color palette fluctuations. Multimedia performance is greatly enhanced with the use of a quad or six speed CD-ROM drive. Small Computer System Interface (SCSI) host adapters cards are recommended, since it can chain up to seven drives off of a single adapter (making available more peripheral slots for other cards, such as an internal modem, and it provides less conflicts. SCSI host adapters with internal SCSI ports can control a hard disk, with a higher disk speed, as compared with IDE drives. SCSI is most useful when you need to have a variety of different devices active or available simultaneously without conflict. It is suggested a minimum of 1 gigabyte (GB) of hard disk (equivalent to 1,000 megabytes). In addition, removable external or internal storage is strongly recommended, particularly when capturing video clip files. Recently a variety of new relatively low cost removable storage had been launched to the market. Two affordable drives have currently a high demand by their user, these are the the 100 MB Zip drive from Iomega and the 135 MB EZ 135 drive from SyQuest. On the other hand, for multimedia delivery system I recommend a much higher storage capacity. The Iomega corporation have available two fast and relative cheep magneto-optical (MO) drives, namely the Jaz. Meanwhile, Pinnacle micro this year (1996) have available a new high storage capacity drive, the Apex 4.6 Optical Hard Drive, which uses a rewritable MOdisk. Panasonic distribute a removable storage that integrates a CD-ROM Drive, its called the PD/CD-ROM Drives. The Panasonic PD/CD-ROM Drives includes a kit that is composed of a SCSI-2 cable, Corel drivers and one PD cardridge. Another alternate data storage is the use of a CD-Recordable (CD-R) drive system. A CD-R drive can reduce bureau cost to a minimum, and speed up your production process. The final "gold master" can be sent to a duplicator. Scanners can be used capture still images from magazines, books, and so forth. Video cameras, VCRs, or videodisc are sources of video input, so that the professor can capture motion or still video. Add-on boards (expansion boards or cards) are units which plug into the computer and either control some essential function or provide a special feature. Typical expansion boards add memory, disk-drive controllers, video support, parallel and serial ports, and internal modems. If full motion video is required for multimedia, we recommend the use of a frame grabber (video capture board). Video capture cards can be used for digitizing analog video sources into AVI (Audio Video Interleave) file format. For better results, use MPEG or M-JPEG capture and editing systems. The most used video capture card is the Intel's Digital Interactive (DVI). This board is connected into the computer's bus and allows for digitizing, compression, storage, and playback of full-motion video. For sound, an audio capture and playback board is required. The sound system represent an important device for your multimedia computer delivery system. It is very important to choose a sound card that is compatible with your CD-ROM drive. Sound cards are also sold in a bundle with the CD-ROM drive. This will assure that both of these multimedia devices work harmoniously.
In addition, the professor must select the software to develop the application as well to deliver it. The operating system must be defined (DOS or WINDOWS). Any specific drivers required to run the application must be determined. A driver is a program that controls or regulates another device (e.g., a mouse or printer). Media drivers enables a computer to work with media devices, such as CD-ROM, sound card, video capture board, and so forth. At this point the professor must decide if he is going to use a programming language such as Pascal or C, or an authoring system such as Multimedia Toolbook, Authorware, Director 4, HSC Interactive, and others. These authoring systems are softwares tools designed specially for the development of interactive CBI multimedia projects. Faculty members may better benefit of these programs, particularly if they lack of programming skills. The selection of the authoring system must be carry out early in the development process. The majority of the authoring systems allows lay out screen elements (backgrounds, graphics, and text), the creation of simple animations, special effects, and on-screen interactions. Some authoring systems permit to define variables for collecting students input information, and interface the interactive multimedia application with peripherals (e.g., CD-ROM, videodisc players). Many authoring tools are capable to interface with programming languages. Before selecting an authoring software, spend some time understanding how the different types of available authoring tools works. The professor must look for the following features that can provide the authoring tool: 1) help tools, 2) hypertext tools (used when text is the primary type of content), 3) multimedia presentation tools, 4) computer-based training tools (include many interactive tasks), and 4) portable document tools (display on-screen replicas of documents formatted for print).
Design. Knowledge of the content and function of the potential application will aid in the development of the preliminary design. In this second phase, the professor should create flow-charts (diagrams describing the operations a computer performs; visual representation of decisions and events) and scripts, so that the final product can be seen. Storyboarding (preparing textual and pictorial displays, drafting the actual instructional messages) is important in this phase. Storyboards includes visual or graphical information, questions, reinforcement (feedback), guidelines/directions, prompts, graphics/pictures, animations/movies, and other key visual sketches that should be incorporated in the proposed multimedia CBI lesson and/or presentation.
Logistics and Production. Logistics refers to the determination and management of the resources materials for instructional design (text, storyboarding sheets, graphics arts, a word processor, persons with experience in instructional design, etc.), resource materials for delivery system (hardware, manuals, experts in software development, etc.), and subject-matter resources (textbooks, reference books, original source materials, films, and other people knowledgeable in the area). The production of a multimedia CBI utilizing an on-line presentation delivery form and/or an interactive/random access CD-ROM application (employing an authoring program) requires the use of a hefty array of commercially available softwares. In addition of the authoring application, the professor may need to enhance his multimedia creation using animation/morphing programs, photo/image-editing softwares, paint and illustration (drawing) programs, digital video and audio software editors, and a bundle of royalty-free CD-ROM media clips (photoCD, bitmaps images, vector graphics cliparts, and video and sound clips), and other software utilities (format converters for graphics, audio, fonts and other file types, screen/window capture utilities, draw/trace programs, etc). There are excellent commercially available cliparts, background pictures/textures, animations, and video and sound clips available on CD-ROM (refer to appendix A). Some recent authoring packages and presentation softwares include audio and video editing tools. Use scanners to digitize pictures and/or slides. Production consist of those steps needed to culminate the multimedia project. During this stage of development, the professor will integrate the multimedia elements into the CBI application. This process is possible by means of authoring software tools which aids in an easy-non-programming manner the proposed interactive multimedia application. The final product should be tested and debugged.
Production of Supporting Materials. Worksheets, diagrams, exams, photographs (PhotoCD or "scanned"), and assignment sheets.
Implementation. The implementation stage may need the employment of a variety of multimedia delivery systems for different kind of multimedia CBI softwares.
Evaluation. To asure a high quality production, the professor must constantly evaluate the multimedia proyect during every stage of the development process. It is imperative to make the required changes according to the results of this evaluation. Once the final product is distributed at the campus computer stations or delivered at the lecture presentation, the professor must assess the degree of achievement from the pre-established goals and objectives. This can be performed by collecting feedback and information from the intended students and members of the faculty of your department. The appropriate feedback must be received from the target students, from experts in the computer field (particularly those devoted to develop educational applications), and from specialist in content of the created CBI application. Assess how the multimedia CBI lesson works by observing the results of real students studying the CBI program and assessing how much they learn. Moreover, the professor can further evaluate the multimedia project by using it and having other people with design experience go through it. This stage is vital, since it will determine the the quality of future multimedia productions. The multimedia project must follow the curiculum standards, and should be employed only as an adjunct learning tool. Areas of evaluation that should be solicited from the students, CBI experts, and faculty members include the following (Price, 1991, pp. 110-116): 1) instructional adequacy (for reaching the objectives), 2) aesthetic adecuacy (appearance), 3) program adecuacy (determine if the application runs as originately planned/disigned), and 4) curriculum adecuacy (according to accepted standards and practices).
CD-ROM Project Planning.
Planning for the developmnet of an interactive CD includes the folowing
initial steps: 1) defining the project and work, 2) Determining the resources
and budget requirements, 3) establishing the project schedule. Before begining
to work with the authoring tool and/or presentation software, the professor
should try to resolve the design components for the CBI interactive delivery,
namely: 1) User interface, 2) interactive branching, 3) determine the ways
and means the user will be able to access the educational components of
the CBI interactive program, and 4) at what time the multimedia elements
will appear in the courseware (Protus, 1994).

MULTIMEDIA IN THE HIGHER EDUCATION SETTING
Higher education must keep up with the current changes in technology. The most recent revolutionary change is multimedia computing. It is the responsability of the colleges and universities to bring up this new technology to the faculty and classroom. The implementation of a multimedia project at colleges and and universities requires a great deal of planning and development of specific strategies. It is suggested to first evaluate the university faculty interests and needs concerning the development of computer-generated presentations for their classes and instructional interactive multimedia applications (Sammons, 1994).
The team approach. The success of a multimedia program at the higher education level will greatly depend on the available human resources. Hardware and software will have meaningless function if the faculty does not know how to use it. A multimedia classroom cant't be developed if the administration of the university doesn't provides the required funding. Oblinger (1992) had suggested the creation of three vital groups for the multimedia project at the educational setting. These are:
Suggested steps for academic multimedia program development. At this point, it is indispensable to organize and appropriately set-up the univerity-based multimedia program. The succeeding list will address over this process (Oblinger, 1992).
Determinants for the incorporation of a multimedia project at higher education level. The effectiveness of interactive multimedia CBI programs at the higher educational setting depends of various factors, such as the available financial resources/funding, the faculty initiate/leadership, staff support, administration support, technical support/services, and available time (Hazen, 1992; Lamb, 1992; Oblinger, 1992; Sammons, 1994). These factor are described below:
Future expectations. According to Dr. Martin B. Solomon (1994), the integration of multimedia at higher education will be adequately developed if the following factors can be implemented:
1. Instead of using expensive multimedia PC systems, the multimedia
can be delivered
by a network.
2. The material developed by means of multimedia authoring softwares
can be
marketed for considerable number of target students.
3. Availability of more commercially high quality multimedia CBI programs.
Roadblocks for the widespread use of multimedia at the higher education setting. It is not an easy task the inclusion of an multimedia instructional courseware at the university ambiency, yet is not impossible. Nevertheless, there are some factors that hinders the prosperity of multimedia programs at higher education. Some of these are the following (Solomon, 1994):
Factors affecting faculty participation in computer-multimedia generated presentations of their classroom lectures. In general, it has been stated that college and university faculty members lags behind in the process of incorporating multimedia into their teaching (Sammons, 1994). Within an already instructional multimedia program at higher education setting, only about 2% to 3% of all the faculty members utilizes the multimedia hardware and software (Sammons, 1994). Why does this happens?. Some answers are addressed from an survey study performed at Wright State University for the faculty members of the College of Liberal Arts' Notebook project (Sammons, 1994).

INTERACTIVE MULTIMEDIA AUTHORING TOOLS FOR THE
CBI DEVELOPMENT AND LECTURE PRESENTATIONS
The development of higher
education software is often a difficult process. Not many educators and
scholars know to write programs. High quality higher education courseware
requires a multi-discipline team approach, in which high-tech programmers
can serve as consultants conjointly with the faculty members of the university.
The complexity of designing interactive multimedia CBI applications and
digital screen show multimedia presentations will be deterrent for those
faculty members working in the production of multimedia materials if assistance
from experts in this field are not readily available. However, multimedia
materials prepared using commercially available authoring software packages
can indeed change this panorama. Current commercially available interactive
multimedia authoring softwares now show great promise for developing effective
interactive multimedia CBI applications and computer-based multimedia presentations.
The authoring process. Authoring is the process of sequencing the CBI application or lecture presentation, laying out media elements on the screen, and entering the instructions for the required interactivity. A multimedia CBI author is the professor that plans and designs the interactive CBI courseware, and the related materials. The tool of the multimedia CBI author's trade is referred to as authoring software. Authoring is the heart of multimedia production, where all of the media elements come together and are assigned a place and time. Those faculty members planning to develop an educational authoring application should be sure to allow plenty of time for authoring, especially if they are new to the authoring software to be using.
Types of multimedia authoring
softwares. Multimedia authoring applications can be grouped into two
categories: 1) sophisticated interactive multimedia authoring tools, and
2) multimedia capable computer-generated presentation graphics (online/screen
or slide show programs), (Head, 1992; Lindstrom, 1994; Wolfgram, 1994,
p. 24). In this section we will discuss first the multimedia authoring
tools devoted for CBI buildup. Later, I will describe
the multimedia capable presentation graphics that can be employed for
the classroom presentation lectures.
Selecting an authoring application. Multimedia authoring software selection is the most important decision you will make for multimedia CBI lessons and/or lecture presentations. Before the professor and/or academic institution engage in the purchase of an authoring software, they should conduct an assessment of the commercially available authoring programs, in which a comparative analysis is performed from a standpoint of software capabilities and ability to support learning objectives (Wulfekuhle, 1994). Those factors to be considered during the evaluation process should be the followings: audio and visual capabilities, level of compatibilty to the existing hardware and software, compatibility and support with multimedia elements, ease of controlling multimedia elements, import capabilities of images/graphics, flexibility/compatibility of the import capabilities and data exchange from other programs (the degree of cross-platform support), degree of dificulty of the authoring program's command language, available testing and feedback options to students, capability to test the student's ability to apply concepts, hypertext-readiness and adaptability to associated multimedia elements, ability to load massive ammounts of information, support of programming variables and/or database elements (their ability to create sophisticated interactive presentations using embedded programming languages) and their hyperlinks capabilities, and required hardware for CBI development and delivery to students, production costs (Wulfekuhle, 1994).
Windows-Based Sophistical
Multimedia Authoring Softwares. These are characterized with the ability
to create worldy-wise interactive CBI applications. They represent the
high end of the authoring tools scale. For interactive multimedia CBI delivery,
the use of an authoring tool will be of great help. Authoring tools permits
the user to engage in a free-flowing exploration. Special features that
contribute to authoring tools' power are things like mixing of various
events in a single frame of the presentation, path-based animation, extensive
text controls, environment controls like controlling when an image is loaded,
and memory management. Some tools also offer accelaration,
which is a process by which the presentation is compared frame by frame
and only the differences between them are stored. This accelerated file
can then be played back at a much greater rate of speed than the unaccelerated
presentation. Some of the typical features of a interactive multimedia
authoring tools are: 1) frame-by-frame metaphor (like a movie), 2) non-linear
flow control,
3) multiple interactive controls, 4) complex transitions between frames
(Wolfgram, 1994, pp. 26-27), 5) cross-platform support, and 6) code incorporation
from external programming languages. Examples of the top multimedia authoring
tools for the Windows environment include Asymetrix'
Multimedia Toolbook, Macromedia's Authorware professional, and Macromedia's,
Director 4. The subsequent paragraphs describes these leading commercially
available authoring packages. Remember to take into account the previous
suggested approach to determine which best authoring tool meets the needs
of your proposed multimedia CBI application.
Multimedia Toolbook. Developed by Asymetrix, it's a well-suited software construction set for education and training. Its also commonly used for marketing demos and tutorials. Its scripting language (called OpenScript) is fairly simple and straigthfoward. Similar to HyperCard on the Macintosh, Multimedia Toolbook builds applications using a book metaphor. The Toolbook application that is created is organized in one or more books. The pages of the book is composed of different elements, such as, objects (buttons, fields, graphics, bitmaps) amd multimedia files (video clips, sound and animation. Multimedia Toolbook supports hypertext features.
Authorware Professional. Authorware professional from Macromedia follows a lineal model and is built on an icon-based programing language. Its used to create interactive courseware, prototypes, simulations, and training applcations. With Authorware you can extend the system with external programing language. Its easy to create interactive simulations with movable objects, drag-and-drop, hyperlinks and path based animations. Authorware builds its applications using icons on a flowline where the position of the icon indicates the order of the event execution. The icons control all the standard multimedia elements like taking user input, controlling internal variables, and displaing graphics, animations, buttons, and video (also playing MPEG). This authoring tool supports playback of Director and Quiktime animation and video. Laserdisc players can be easily access. The program also supports hypertext and hypermedia, which allows to perform interactive branching, making links from text/objects to other media (video, graphics, sound) in the application. Authorware can create applications for either a PC or Macintosh platforms. The latest version of Authorware (3.0) also adds Open Data Connectivity (ODBC) support and Object Linking and Embedding (OLE 2.0)
Macomedia Director. Available of Macintosh platform and for Window's operating system. The files created by Director are compatible with Windows, Macintosh and 3DO. This authoring software had been very popular in developing several award-winning commercial CDs. Director supports the basic multimedia elements needed for a the CBI intercative production, namely, video, sound (.WAV and MIDI) and hot spots. The scripting language that use Director is called Lingo. Based on a visual programming metaphor called a score (borrowed fron the musical score metaphore of MusicWorks, which displayed its notes in a bar graph manner), Director assign steps and sequences to objects and actors on the score. Director's movies contain a Cast (a colection of images, sounds, text, and lingo scripts) and a Score (shows positions of Cast members on a frame by frame basis). Lingo commands are used to create interactivity.
Multimedia capable presentation graphics softwares. Most faculty see multimedia as a presentation tool for their classroom lectures. User-friendly presentation softwares are available at the commercial market. The first commercially availalable presentation graphics possessed limited multimedia features, and were designed using the "slide" metaphor. Consequently, these initial presentation softwares was also known as slide show presentation softwares. The initial slide show programs were based on the construction of presentation graphics. By definition, a traditionally presentation graphic software are those capable to create visually enhanced charts and graphics (text, xy charts, pie charts, maps, and pictorial images and drawings) to be used for classroom lectures by means of direct electronic display of these images using computer driven liquid cristal display (LCD) panel or video proyector. The following are typical slide show program features: 1) slide-by-slide metaphor (build a slide, wait, build a slide, wait...), 2) linear flow only, 3) singular interactive control (timing or interactive, not both), 4) simple (if any) animation features, and 5) simple transitions between slides (Wolfgram, 1994, pp. 24-25). With the evolution of the microcomputers, slide show programs incorporated other special effects features that allowed the presentor to build a slide, wait a specified amount of time or for a keypress (or, in some cases, mouse click), then go to the next slide. Normally, each slide can be composed of bullets, animations, icons, images, and background art. Different background templates for automatic creation of entire presentations are available. Current presentation graphics softwares had been improved with multimedia elements and hypermedia capabilities by which powerful interactive multimedia online screen show presentations can be delivered for classroom lectures and business presentations. They usually allow for the playing of music and sound effects and newer versions allows interfacing to video files. These innovative presentation softwares posees new powerful working tools, such as: 1) full featured outliner, 2) simple user interface, 3) powered animation and system controls, and 3) non-linear (branching) data paths (Wolfgram, 1994, p. 29). The most used window-based multimedia-capable presentation sofwares include Asymetrix Compel, Gold Disk Astound, Harvard Graphics, Microsoft Powerpoint, Adobe Persuation, and WordPerfect Presentations.
Compel (Asymetrix). This program is oriented toward multimedia presentation developers. Compel its supplied with 154 slide templates groups. Each Compel's groups includes a different slide-style set, including placeholders for video, animation, sound and text, and charts. Within Compel you can create a variety of charts, including area, bar, column, high-low-close, line and pie charts. The effects menu allows the connection of objects to media links (sound, video, animation) and hyperlinks (branching another slide or other application). Slide transitions and bullets transitions are included in the effects menu. From Compel's presentation, the professor can print speakers notes and audience handouts. You can add sound in the form of .WAV files that are triggered by various actions from within the program.
Astound 2.0 (Gold Disk, Inc). Following the steps of Compel, Astound's features provide multimedia-hypermedia tools for lecture presentations, integrating a slide sorter, slide outliner, and a editor display window. A peculiar tool of this program is his Timeline window. This function synchronize object animations. Astound incorporates extensive OLE integration. The developer can access digital video and animations from Astound's Place Video tool. A well-designed audio editing tool is included in this package. Version 2.0 incorporates Astound Studio, in which the developer can create and edit the audio, video, graphics, and animation files required for an multimedia presentation. This utility includes an Image Editor, and Actor Editor, Animation Editor, Video Editor, and Graphic Editor. Multimedia file types that can handle this program includes .WAV and MIDI files, graphics (.BMP, .PCX, .TIFF, .GIF, .CGM, and Kodak Photo CD images) and movie files (.AVI, QuikTime, AutoDesk or Gold Disk animation). Astound also includes path animation for objects. Import capabilities of the charting functions allows the access of datasets from Exel and Lotus 1-2-3 as well as delimited text. With OLE, this program allows links to spreadsheets and other Windows applications.
Harvard Graphics 3.0 for Windows (SPC Software Publishing). Harvard Graphics for Windows includes a Video Player, Autodesk Animation Player and 15 animation clips. Animation Player-compatible files can be embeded as OLE objects in any slide. Video for Windows .AVI clip files can be set to run within a slide by setting the Video Player to auto-playback mode. Harvard Graphics ScreenShow control the program's slide transitions and audio elements. HyperShow function incorporates interactive control of ScreenShow and can also launch playback with the Video Player. Harvard F/X is a separate application included with the Harvard Graphics package for applying a spectrum of special effects to a presentation.
PowerPoint 4.0 (Microsoft, Inc.). Is one of the most popular presentations programs. Text can be entered directly into template slides or in outline form. The program's composition display include: Outline, Sorting, Show, Speaker's Notes and Slide Creation screens. Pre-designed color system are available, slide transitions effects, linkage to CD-quality sound (MIDI, waveform audio), and trigger digital video clips (AVI files) or animation files. PowerPoint uses OLE 2.0 to link and embed media objects from other applications. Windows Media Player can be used to play movies.
Adobe Persuation 3.0 (Adobe Systems Corp.). Supports QuickTime Video or any other movie format that has a Windows 3.1-compatible MCI device driver. Starts in an outliner, where you select the graphic design layout for the entire presention from a collection of style templates. Under the slide's headings, you can select a bullet or text to type the subheadings. Persuasion's graphical tools provides 87 chart types. A strong set of drawing tools are available. Interactivity is limited to branching to other slides. Runtime player is available for Windows, DOS and Mac.
Word Perfect Presentation 3.0 (Word Perfect, the Novell Applications Group). The process of creating a presentation is facilitated with the utility Show Expert and Coaches. The program allows eye-catching slide transitions. Presentations offer the creation of various types of graphis and charts, including area, bar, line, mixed, pie, radar, scatter, surface, table, bullets, data and organizational charts. Multimedia supports include sound (MIDI, and CD sound tracks, images (TWAIN support for scan images directly into the program). Presentation lets you generate speakers's notes to accompany the slides. This program employs OLE 2.0 to insert media clips into the presentations created. The file is linked by copying it to the clipboard and then pasting the file from the Edit menu.
For effective multimedia presentations for your clasroom lectures, follow these general rules (Blaize, Steven, 1996, p. 46): 1) keep the presentation/message simple, clear, and stick to the point, 2) to emphasize the current topic of discussion, use sound or another special effect, 3) avoid endless slide transitions, 3) Rehearse your computer presentation. Before going to the classroom, you can show your presentation to some faculty members and get advice concerning those posible obstacles that impairs the delivery of your lecture topic and main meassage.
Utility Software Tools Used the Enhance the the Multimedia Online Presentations and/or Interactive Authoring applications
Animation softwares. Animator (Autodesk) is the first choice among the comercially available 2-D animations programs. Animator is used for 2-D animation, paint, and sound synchronization.
Morphing softwares. Morphing is the process of changing one image into another over a time sequence.
Paint/image processing
packages. These softwares creates and/or alter images to
make backgrounds and graphics.
Video and audio editing
porgrams. The quality of the multimedia project will heavily depend
on the type of video and sound you will incorporate. These programs should
help improve quality of the captured video and/or sound.

THE PRODUCTION OF THE EXERCISE SCIENCE AND HEALTH CBI DELIVERY
Softwares used. As
a faculty member of the Physical Education Department at the Interamerican
University, Metro Campus, I begun to mature some interactive multimedia
proyects. My first experience was using presentation graphic softwares.
Harvard Graphics for DOS was the begining. Later, with the improvements
of Windows operation system, and the development of powerful multimedia
capable Windows-based presentation softwares, I made a radical switch to
the Windows version of Harvard Graphics. Its seems to me a better choice.
With Harvard Graphics for Windows, I was able to produce a variety of standard
graphics (pies, bars, x-y charts), as well as other types of presentations
graphics (bullets, tables, organizational charts, title, drawing charts).
In addition, with Harvard Graphics for Windows I developed custom made
drawings utilizing his drawing tools. The Harvard for Windows drawing tools
was also used to make annotations and other designs within the standard
graphics created. Harvard Graphics for Windows are packed with a variety
of filters for the import of images created in another graphic program
(examples: CDR, PCD, WMF, TIFF, PCX, and others). Moreover, a collections
of over 500 simple clip art drawings are provided by the symbols library
of Harvard Graphics for Windows. Harvard Graphics also allows the import
of raw data created from differente programs, such as, Lotus 1-2-3 and
Exel spreadssheets, ASCII files and the Windows Clipboard. Harvard Graphics
can organize the presentation in slides (or charts). All related charts
(slides) are grouped into a "presentation", and stored together
as a single file. These slides can later be organized into a "ScreenShow,"
using slide transitions special effects and sound. I begun using Harvard
Graphics for Windows to produce 35mm slides (using a film recorder) and
overhead transparencies (printing the slides in an color Hewlett Packard
[HP] Deskjet). At present, I use Harvard Graphics for Windows to create
"ScreenShows" exported to a runtime file, and using the Harvard Graphic
Runtime Player to deliver my presentation. These Runtime files are displayed
by a LCD panel proyector for my lecture classroom presentations.
Time came when a new well-designed
multimedia-capable presentation software was launched to the market. This
was Compel version 1.0 for the Windows ambiency. Hands-on faculty training
workshops of this new multimedia presentation software prepared me with
the needed skills for the development of more sophisticated interactive
multimedia presentations. Compel is a multimedia presentation software
that organize visual aids or "slides", so that it can be delievred by means
of a computer screen or with a slide or overhead projector. Similar to
Harvard Graphics for Windows, the presentation is created by adding slides.
The Compel slides represents one screen of information (text, graphics,
charts, buttons for multimedia file links) of the presentation. A screen
show delivers your production stored as a presentation file. Such presentation
can be enhanced with the incorporation of multimedia files, such as video,
animation, and sound effects. In addition, Transitional effects (as well
as sound) can be added between slides and Compel animation. As in Harvard
Graphics for Windows, the multimedia presentation can be reformated to
the deliver method you desire, namely, 35mm slides, overhead transparencies,
computer screen and/or proyector system (e.g., LCD panel). The slides created
within Compel can be printed as handouts and speakers notes for the students.
Compel also includes a Runtime player, so that the presentation can be
distribuited as a stand-alone show. My current lecture presentations employs
a combination of both multimeda-capable softwares (i.e., Harvard Graphics
for Windows and Compel). I take advantage of the hyperlink tool of Compel
to launch a Harvard Graphic ScreenShow runtime presentation file.
My first experience with
an authoring software tool was Mutimedia Toolbook. Multimedia Toolbook
is a software construction set used to develop Window's applications. Toolbook
is an object-oriented development environment that provides graphical drawing
tools for creating objects and a full-featured object-oriented programing
language called Open Script for programing object's behavior. Toolbook
provides the following authoring elements: 1) hypernavigation, 2) tools
for creating graphical screens without programing, 3) a programing language
called Open Script, and 4) tools for editing and debugging applications.
Toolbook can be used for: 1) information production (handbooks, scientific
research results, references), 2) development of training packages, courseware
and online presentations, 3) information collection (address book, records,
catalog, and 4) creation of prototypes for applications. Toolbook is event-driven.
Toolbook functions by means of events generated by users action (e.g.,
pointing and clicking with the mouse). Multimedia Toolbook also function
by predefined objects with built-in behaviors. With Toolbook it could be
created applications, such as: 1) hypermedia programs (e.g., encyclopedias),
2) interactive training applications (e.g., tutorials, kiosks), 3) database
applications (e.g., mailing list, 4) games that use graphical elements
(e.g., board games, card games, or games with animation). The term application
refers to a computer program that performs specific task. The Toolbook
application that is created is organized in one or more books,
which are designed for a particular purpose. The multimedia version of
Toolbook adds animation, sound and video to the book. Drawings, scanned
images and color can also be incorporated in the book created in the authoring
software. The book created in Toolbook is divided into pages,
which represent the application's screens. The application book consist
of pages and scripts. The scripts carry out
the actions you want the the book to perform.
With the above authoring
multimedia softwares I begun building up my multimedia presentation lecture
classes under the Department of Physical Education. The courses developed
(and still under revision) are: Anatomy and Kinesiology,
Health
and the Individual, and Nutrition for Sport Trainning.
This was not an easy tasks. Nevertheless, technical help was readily available
through the Center for Instructional Development. Multimedia elements incorporated
in my presentation included: 1) bitmaps images/pictures (digitized with
Hewleet Packard (HP) ScanJet IIc scanner, captured screen areas with Hijaak
Pro 3.0, and commercially clips, using PhotoCD and TIFF file formats),
2) vector graphics images (royalty-free clip arts, using Windows metafile
format [WMF] files, and traced bitmaps exported from CorelDraw 5.0
into WMF formats [This process was necessary to import such WMF file into
Harvard Graphic presentations]), 3) video clips (captured video clips using
Intel
Smart Video Recorder video capture board, commercially available video
clips, using audio video interleaved [AVI] format), 4) animation (Autodesk
flic [FLC, FLI] formats), 5) sound (commercially available music and special
effects sounds employing waveform [WAV] file formats).
This development process
of my multimedia presentation lectures required other windows-based software
products that supported and enhanced the quality of my presentations. These
Windows packages utilized were:
1. Image/photo and drawing editing softwares. Corel Photo-Paint 5.0 used to edit my scanned bitmap images. CorelTrace 5.0 for tracing scanned bitmaps into a vector graphic format (EPS format). CorelDraw 5.0 to edit, apply color, and export into WMF format the traced encapsulated postscript (EPS) format images. Hijaak Pro 3.0 to capture areas from Windows screen.
2. Animation and morphing softwares. Autodesk Animator, and AutoDesk Animator Pro to create animations. PhotoMoph 2.0 for morphing images into FLC and AVI formats, ASYMETRIX 3D F/X to create 3D buttons, snapshots (bitmaps from a created scene) exportable to Compel and Multimedia Toolbook, and animations (saved in .AVI format) that can be embed in an Object Linking Embedding (OLE) container application.
3. Video capture and editing softwares. Microsft Video for Windows (VFW) to capture, edit and save frame-grabded full-motion video clips from an video recorder (VCR) into AVI formats. VFW is a utility that capture still or motion video and records it on the hard disk.
Hardware used. The development of my multimedia presentation utilized the multimedia-computer stations and peripherals (scanners, removable hard disk and video capture boards) connected in a network located at the Center for Instruction Development of the Interamerican University (Metro Campus). My personal home-based multimedia system was also used during my off-campus free time. The development system was composed of the following computer hardware and supporting multimedia equipment:
1. Computer and peripherals. Microprocessor Intel 80486 DX with a processin speed of 33 megahert (MHz). The random access memory (RAM) was 8 megabytes (MB). Video graphics card with a Super Video Graphics Adaptor (SVGA) resolution and 1 mb of RAM. Two hard disk drives that sum aprroximately 800 MB, IntelliPoint Microsoft mouse. Double-speed CD-ROM drive that supports KodakTM Photo CD format.
2. Monitor. I used an high resolution SVGA monitor.
3. Sound card. Creative Labs Sound Blaster Pro (for ISA).
4. Audio speakers. Employed to monitor quality of the sound clips incorporated in my presentations.
5. Video Capture card. Initially I captured by videos with the Creative Labs Video Blaster card (model RT300). I had some problems with dropping frames during the capture. Looking for a better quality of captured frames, I switched to Intels Smart Video Recorder capture card.
6. Scanner. Employed to capture full page images (still images) from magazines, books, and photos with a HP ScanJet IIc scanner.
The multimedia delivery system employed during my lectures presentations in the electronic classroom included the following hardware and accesories:
1. Computer system/peripherals. Microprocessor 80486 DX2 and 66 megahert (MHz) speed. 8 MB of RAM. Video graphics card with SVGA resolution. Internal removable SyQuest cartridge and Drive of 270 MB. Mouse. Double-speed CD-ROM drive.

THE FUTURE OF MULTIMEDIA IN HIGHER EDUCATION
The multimedia at higher
education holds great promise for academic instruction. As we move into
the twenty-first century, more higher educational institutions will be
shifting toward the development of the appropriate multimedia-based electronic
classrooms conjointly with more faculty training for the production of
interactive multimedia CBI applications and computer-generated presentations
for the lecture classrooms (includng multimedia presentations generated
and displayed through microcomputers), which will would provide an enhancing
learning environment.
Multimedia has a healthy
future. The multimedia revolution will continue his high-profile in the
general business, and in education. Interactive multimedia should continue
achieving success as a teaching tool. Multimedia will harvest new creative
potential educational softwares developed by the faculty. More quality
instructional media custom designed and integrated with the instructor's
normal teaching technique will be developed.
This technology will continue
to grow, showing promise for the enhancement of the presentation lectures
of the professors, as well as for an individualized self-study application
that will aid the higher education learning process.
More educational programs
will be developed for Windows operating systems. Windows allows to produce
better graphics, providing more detail and smoother animation than DOS.
More powerful and effective multimedia capable presentation softwares will
be developed.
With adequate funding and
faculty support, computer-based multimedia delivery systems could become
the most common form of instructional technology on college campuses by
the end of the decade. The future challeges will be the development of
curriculum-supported interactive multimedia CBI applications that can be
used as an adjunct learning tool for the faculty members at the higher
education level.
I believe that in a near
future, a greater number of faculty departments at the university institutions
will be involved in the creation of multimedia materials, and the development
of appropriate technology classrooms, that is, new infrastucture development
of multimedia electronic classrooms. Consequently, more classrooms will
be devoted to design and deliver educational multimedia programs. However,
future use of effective electronic classrooms will depend of several factors,
such as: ease of operation by the faculty, time needed to learn, availability
to the professors, reliability of the system, and level of delivery power
(Kalmbach, 1994).
Better and more users of
faculty members developing multimedia projects will depend on the time
they have, the support that they will be given, and the the feasibility
of an easy-to-use hardware and softwares (Sammons, 1994).
The success of instructional
multimedia at higher education will depend on the future cost of hardware
and software, the standardization of the multitude of peripherals that
are used in developing multimedia products. Multimedia delivered inexpensible
over a network is better, less cost (Solomon, 1994).
The demands for a better
total quality at the higher educational settings, particularly the teaching
quality (or teaching excellence), will position these higher educational
institutions to provide revelant instructional technologies to the university
community. The challenge is to stay abreast with the rapidly changing
of instructional multimedia, so that the university institutions can assure
a high quality of education to their students, and get them ready for the
expected technological changes of the incoming century. Moreover, These
institutions should provide to the faculty members with the required resources
to be competitive both in the classroom and in their research endeavors.
Such evolving technology
will continue to change in the hardware systems. Trends indicate increasingly
better computer interfaces, decrease in the physical size of computer systems,
better and higher capacity of digital data storage, both fixed, and removable.
The trends in presentation graphics are increasingly processor speed, higher-resolution
displays, and easier-to-use software with expandable clip art library and
high-quality templates, still and motion images.
Current trends indicate
an exciting future for instructional multimedia at higher educational institutions.
The emergence of the authoring multimedia development will continue. Trends
indicate increasingly easy-to-use, human-computer interfaces, such as development
of remote controls. A decrease in physical size will be evident, with larger
permanent and removable storages capacities and faster access time.
In brief, the exciting near-comming
years will impose the higher educational institutions to integrate interactive
multimedia CBI applications into the curriculum, so that it can be assured
an enhacement of the higher education total quality, particularly the quality
of the teaching-learning process. The learning through interactive CBI
lessons will heavily depend of problem-solving situations. Multimedia computing
will play a more prominent role in the classroom. Learning will be more
student-paced, with time for individualized instruction.

Description
In order to empower the multimedia
and hypermedia capabilities of the proposed development of interactive
multimedia CBI applications and/or computer-based multimedia lecture presentations
it is necesssary to incorporate multimedia elements (text/font, images/graphics,
full-motion video, animation, and sound). Actually, there are two ways
to include these multimedia files to the instructional CBI lessons and
presentations. One way is to develop custom-based multimedia elements utilizing
special hardware/equipment and software, such as a scanner, and/or direct
digitizing of photos and video by means of special digital cameras and
camcorders, respectively (to produce images/photos), video capture board
(to develop full-motion video clips), AutoDesk Animation softwares (for
flic animations), and Sound Blaster compatible cards (for audio input and
editing). The alternate form for incorporating multimedia files into our
presentations and CBI lessons is use royalty-free commercially available
media clips (bitmap photos/images, vector graphic cliparts, MIDI and WAV
sound/music files, AVI video clip files, and animation FLC/FLI files).
The following is a list of royalty-free resource materials of media clip
files that are commercially available and that I had employed for my multimedia
presentations and interactive applications:
