Computer Based TrainingCOMPUTER-BASED TRAINING
Computer-based training (CBT) instruction is a very diverse and rapidly expanding spectrum of computer technologies that can assist anyone from a child to a doctor in teaching and learning a particular skill or process. This paper will describe the types of CBT and the disadvantages and advantages of using CBT. Examples of CBT applications include guided drill and practice exercises on learning a science such as physics or mathematics; the computerized visualization of complex objects such as the human body or the inner workings of an rocket engine, and the interactive communication between students and teachers in learning a foreign language. Computers over the past five years have changed dramatically from the simple paperless typewriter with only a floppy disk to the multimedia system capable of playing back movies, music, and access to the Internet.
There are several types of CBT instruction programs. Information that helps teach or encourages interaction can be presented on computers in the form of text or in multimedia formats, which include photographs, videos, animation, speech, and music. The guided drill is a computer program that poses questions to students, returns feedback, and selects additional questions based on the students' responses. Today's guided drill systems incorporate the use of multimedia with the addition of an instructor lecturing the student on the proper methodologies. Computers also can help students visualize objects that are difficult or impossible to view. For example, computers can be used to display human anatomy, molecular structures, or complex geometrical objects. Exploration and manipulation of simulated environments can be accomplished with CBT�ranging from virtual laboratory experiments that may be too difficult, expensive, or dangerous to perform in a school environment to the complex virtual worlds like those used in airplane flight simulators or movies such as Dante's Peak or Jurassic Park. CBT programs can also facilitate communication among students, between students and instructors, and beyond the classroom to distant students, instructors, and experts.
