  25. 25. COMPACT DISC READ ONLY MEMORY (CD-ROM) small disc which can incorporate sound, motion, and video information on specific topics. It is played in the CD player.
  26. 26. COMPUTER ASSISTED INSTRUCTION(CAI)  soft ware that includes test and activities for individualized instruction, the performance of students are being monitored by the system.
  27. 27. Advantages of the Computer in Teaching and Learning
  28. 28. Lucido and Borabo (1997) gave the following advantages of using the computer: 1. It allows students to learn at their own pace by having control over the rate and sequence of learning. 2. Learning is reinforced by way of high speed personalized response.
  29. 29. 3. There is a positive affective climate for learning especially for slow learners. 4. Color, music, and animated graphics add realism and appeal to drill exercises, laboratory activities, simulations and others. 5. Progress in learning is easily monitored with the record keeping ability of the computers.
  30. 30. 6. Massive information is put at disposal of the teacher; information which he can control as he keeps contacts with the learner. 7. Other benefits relating to: motivated work, improves efficiency, broader memory capacity, time savings compared with conventional modes of learning.
  31. 31. Disadvantages of Computer in Teaching and Learning (Lucido and Borabo, 1997)
  32. 32. Disadvantages of the Computer in Teaching and Learning 1.Computerized instruction is relatively expensive. The cost and benefits must be assessed to ensure optimal gains.
  33. 33. Disadvantages of the Computer in Teaching and Learning 2. There is some lag in the production and design of computers for instruction. High quality direct instruction materials are not readily available and may require compatibility due to exclusiveness of some educational programs or soft ware.
  34. 34. Disadvantages of the Computer in Teaching and Learning 3.Creativity may be stifled if creative original responses are ignored by the linear, lock-step control learning process in the case of run-of-the mill computer instruction materials.
  35. 35. Disadvantages of the Computer in Teaching and Learning 4.The novelty effect associated with CAI may decrease as computers are made more easily available at home and in the workplace.
  36. 36. Indeed, with the computers the gateways of personal, educational, social and even economic progress has been widely opened.
  37. 37. With computers we can do most everything. In educational parlance, teachers and students as well only need to lift a finger to do research and to present illustrations, pictures and graphics by way of animation to make teaching and learning more impressive, more interesting and permanent.
  38. 38. One can also access up to date information across the world anytime by chat or e-mail, thus enriching knowledge and information.
  39. 39. • sometimes called simply "the Net," is a worldwide system of computer networks. • instant source of information. • is a valuable medium for communication. Source:http://searchwindevelopment.techtarget.com/sDefinition/0,,sid8_gci212370,00.html
