Written programs or procedures or rules and associated documentation pertaining to the operation of a system and that are stored in read/write memory.
Packages developed at NCERT:
1. The Audio Visual Computer Aided Tutor System(AVCAT)
The instructional material is composed from blocks of instructional audio messages and their supporting Pictorial images, with questions at the end of each block to assess the students’ progress.
The audio messages and the instructional material are stored on C90 audio cassettes. The visual content of the lesson is held on 35 mm slides.
Both the audio and slide delivery subsystems are rapid random access devices.
2. The Computer Audio Visual Instruction System (CAVIS)
The system provides a teaching facility that integrates the use of video cassette, pictures, text, videotext and animation, and presents these on a single television screen with supporting sound effects use in an instructional process. In addition, a variety of Computer Based Trainings (CBT) are available.
The complete workstation includes
a VCR, a student keypad, a pair of headphones,a TV display monitor, the author’s keyboard and a micro computer unit that is fitted with a magnetic disc storage system which contains the control software.
This is responsible for handling the overall operation of the system and also guides the direction in which learning progresses as a result of student interaction with the system.
3. Computer Guided Learning System(CGLS)
students attend a ‘Guided Learning Centre’ at times when it is most convenient for them to come. A Guided Learning Centre course is composed of a series of modules. Each module is self contained; the student’s objectives and text for that module, directions to complete the module, examples, exercises and progress checks or examinations. Each student covers topics step-by-step and can regulate the pace and depth of learning. Material may be recapped or repeated until a satisfactory level of understanding has been reached.
4. The Interactive Video Information System (IVIS)
Multimedia workstation consists of
a keyboard, high resolution colour Cathode Ray tube (CRT) display, a pair of headphones (and/or audio speakers), a video disc player and a microcomputer system. The video images presented on the display monitor can be dynamic or still frame. Two audio channels are available. Depending on the lesson material, being presented, the audio could consist of narration, a life like conversation, special sound effects, music or any combination of these.
IVIS trained students learn up to 53% faster and with better retention-than students trained by conventional methods.
