- 2. The Context Computers and their use in education and distance education Communication and use of satellite Computer networks and Internet
- 3. How computers are being used? For teaching For learning For office use and administration Computer assisted learning and computer managed learning Multimedia and CBT Computer media in education
- 4. Computer media in distance education Information processing ( I learn by using computer ) Interaction ( I learn by interacting with the computer ) Communication ( I learn from others )
- 5. Satellite communication Different from terrestrial communication Geosyncrhonous (orbital period around the earth is 24 hours) Teleconference is possible today
- 6. Advantages of teleconference Reaching remote places Quality of instruction Immediacy of feedback Cost-effective Familiar instruction mode
- 7. Types of teleconference Audio-teleconference Video-teleconference (one-way and two-way) Computer conferencing (VSAT based)
- 8. Problems of teleconferencing Poor integration of teleconference to teaching and learning Poor interaction and student attendance Lack of information about teleconference Poor quality of presentations (talking head type) Poor instructional design and technical support Poor organization and reception end More is not good ; more interaction kills
