Evidence collected on the effectiveness of four educational technologies is briefly reviewed. The authors conclude that there is reasonable evidence that computer-assisted instruction can have at least a modest effect on improving learning and probably more when its instructional approaches are properly matched to instructional objectives, that…

Programmed instruction (PI) was devised to make the teaching-learning process more humane by making it more effective and customized to individual differences. B.F. Skinner's original prescription was modified by later innovators to incorporate more human interaction, social reinforcers and other forms of feedback, larger and more flexible chunks…

Discussion of effective computer-based training (CBT), or computer-assisted instruction, emphasizes that the media used should be selected to support and deliver the message, not overpower it with unnecessary elements. Topics include computer as tutor; design and authoring tools; interaction; procedural versus principled tasks; and information and…

Describes four studies, one experimental and three comparative, that were conducted with university students to assess the instructional effectiveness of separate animated computer tutorials illustrating dynamic processes in microbiology. Results indicated a significant advantage for subjects in the animated condition as opposed to a contextual…

The term "design" is being understood more and more as a methodological process, together with its acceptance as the result of such a process. As a process, it is a stage in the courseware engineering life cycle which primarily focuses on rendering the development process more effective and on enhancing the qualities of the finished system,…

In this study, the Bystander Turing Test (BTT) paradigm is used to determine whether participants rate particular dialog moves in tutoring transcripts to be generated by a computer tutor, AutoTutor, or by a skilled human tutor. Currently, AutoTutor initiates a conversation with the learner by posing a question or presenting a problem for the…

Describes a study of elementary school students grades three though six that compared two methods of keyboarding instruction, one that used a tutorial computer program and one that involved the teacher and lesson plans. Results indicate the more teacher-intensive method was more efficient and effective than the computer program. (LRW)

Describes a study of university students that investigated the effects of a variable unique to Internet-based learning, namely download delay of instructional materials. Discusses a simulated online teaching tool that measured the effects of download delay of images on test performance, time spent on the material, end-user satisfaction, and…

Describes a computer tutorial that teaches the fundamentals of stimulus generalization in operant learning. Concepts covered include reinforcement, discrimination learning, stimulus continua, generalization, generalization gradients, and peak shift. The tutorial also reviews applications in human and animal situations. The content is appropriate…

CIRCSIM-Tutor is a computer tutor designed to carry out a natural language dialogue with a medical student. Its domain is the baroreceptor reflex, the part of the cardiovascular system that is responsible for maintaining a constant blood pressure. CIRCSIM-Tutor's interaction with students is modeled after the tutoring behavior of two experienced…

Examines the literature on the effectiveness of computers in social studies instruction and learning. Topics include drill and practice, tutorials, study guides, games and simulations, inquiry and problem solving, graphics, and word processing and writing. Contains 58 references. (LRW)
