Computer Assisted Instruction (CAI)

Computer-assisted instruction makes use of multimedia software in the learning process including text, video technology, graphics, sound, and Internet technology. Computer-assisted instruction is heavily used in the growing field of distance education. Traditionally, computer-assisted instruction, like programmed instruction, has been linear in nature. Web based instruction on the other hand is nonlinear. Instruction using Internet protocol makes use of technological features that traditional computer-assisted education does not, such as hyperlinking, synchronous and asynchronous conferencing, real-time audio and video, as well as 3-D virtual reality.

There are numerous unique features of CAI which make it an exciting field. One of the most useful is its adaptability for distance learning. Before the dominance of microcomputers, distance learning was mostly accomplished through PI or the US mail system supplemented by telephone contact. On the contrary, CAI provides regular and timely interaction with the instructor and current feedback. Students can repeat tutorials as often as needed and work at their own pace. CAI also can be used with greater numbers of students than a traditional classroom would hold. CAI and web-based instruction have opened avenues of access to individuals with disabilities that were not possible before.

Intelligent computer-assisted instruction (ICAI) is programmed so that the CAI adapts to the student's individual needs. It acquires information about the student's current knowledge of a subject and his/her goals in learning the subject and then creates a user profile based on this knowledge. It can then adjust itself to the individual student.

Web-based instruction is unique in that students and/or instructors can communicate with each other anywhere in the world within seconds via the Internet. Feedback from the instructor can be obtained immediately.

Many of the advantages of PI are also advantages of CAI and web-based learning. The advantages of CAI include flexibility for students so that they can work at their own speed at the time that is best for them. With web-based instruction, they can work at home, at school, or anywhere there is a computer with an Internet connection. Used with distance learning, it allows students with handicaps or learning disabilities the opportunity to learn in a less restrictive environment. Also, students who enroll in courses via CAI, including web-based classes, gain an opportunity to learn computer skills, which benefit them in many aspects of their lives.
