Computers are commonly used in classrooms for educational purposes, including Computer Assisted Instruction (CAI) and Computer-Based Education (CBI). CAI can be used alone or in combination with traditional teaching methods, and has been effective in increasing student achievement. It is used in all levels of education and various fields, including law and vocational training. CAI can also be personalized for individuals with disabilities or limitations.
Computers are a familiar sight in classrooms in the twenty first century and technology has been used to streamline many educational activities. There are different types of educational computer use, and not all classroom computer use is considered Computer Assisted Instruction (CAI). Educational uses of computers that are considered CAI or computer-based education (CBI) are those instances where instruction is presented through a computer program to a passive learner, or where the computer is the platform for an interactive learning environment and customized .
Within the broad definition, computer-assisted instruction can take different paths to the same end. One example is how this medium of instruction is used in relation to other teaching presentations. The CAI can be used both in isolation, assuming full responsibility for imparting instruction to students, and in combination with conventional teaching methods, i.e. in presence. Research has shown that the combination of conventional instruction and CAI was most effective in increasing student achievement scores.
Computer-assisted instruction is used across the entire spectrum of education, from kindergarten to vocational school. It was offered in a wide variety of fields, including all major school subjects taught in elementary and secondary schools. At CALI, the Center for Computer-Aided Legal Education, law students from all over the United States and other countries such as Belgium, Brazil, Canada, China, Denmark, Ireland, Kenya, Korea, Mexico, Netherlands, Nigeria , Russia, Singapore, South Africa, Sweden and Taiwan have access to CAI law school classes to supplement their education.
Computer assisted instruction has also been increasingly used in a large number of work areas. It has been used to teach novice nurses how to give intravenous injections, to teach jet engine mechanics in US Air Force maintenance tasks, and to provide safety instruction for food service workers in an urban hospital.
CAI can also focus on smaller segments of the population. Computer-assisted instruction has also been used to personalize learning for people with learning disabilities, language limitations, and physical limitations. In the latter case, screen reader programs can cater to visually impaired users, and a variety of specialized interactive devices, such as roller wheels, joysticks, and large keyboards can be used by a person when a standard mouse or keyboard represent a challenge.
