Increasingly, higher education institutions and businesses are developing distributed learning systems to provide continuing job-related and professional education. Principles and examples of distributed learning and support systems that promote individual development are outlined, considering issues of motivation, speed of program development,…

Computer-delivered, case-based instruction can provide medical students with valuable clinical diagnostic experiences before encountering real patients. Diagnosis requires physicians to understand and use causal reasoning for prediction. Such reasoning may be scaffolded in the design of computerized learning environments. Scaffolding of causal…

Proposes improved, more computer-intensive statistical techniques using bootstrap and permutation tests for analyzing results of student evaluations of teaching. Application of these methods resulted in narrower (more precise) confidence intervals and larger significance levels than more classical methods. Results indicate the new techniques…

The evolution and design of a videodisk recording for classroom use in teaching aesthetics at the college level are described. The program presents an internationally notorious case study in art forgery. It facilitates three crucial tasks in visual art study: access to art and related information; detail; and analysis. (MSE)

A study evaluated the effectiveness of an interactive videodisk program in guiding law students through development of a civil rights court case. Results were mixed, with positive student perceptions but little improvement in performance. It is concluded that more needs to be known about this kind of orienting instruction. (MSE)

An experiment applied the theories of knowledge engineering and expert systems to science instruction for junior high school students. The model encourages a more creative, constructivist approach to teaching certain science concepts and skills while fostering improvement of logical thinking, communication, and independent learning skills. Results…

The Jefferson Notebook system, based on a model of integrated research and instruction, is a computer program to aid in creation of hypertext instructional materials. It is currently used in college writing and academic courses. Its authoring features allow teachers to build instructional resources and integrate research and writing. (MSE)

A theoretical description of hypertext is presented, and three applications of hypertext are discussed: electronic studying allows linkage of electronic note cards for writing and interrelating concepts; literary exploration allows construction and interpretation of stories with provided literary elements; in qualitative research, hypertext helps…

Development of two interactive videodisks in space science for middle-school-age children is described, and suggestions for development of affordable and successful interactive products are offered. The first interactive program is a touchscreen exhibit designed for museum use, and the second is a classroom tool for teaching a planetary sciences…

A set of guidelines for evaluating interactive multimedia used in college instruction is offered in the form of 10 "commandments" illustrated with humorous anecdotes. They stress descriptive approaches to research and evaluation, including modeling methods that integrate quantitative and qualitative data. (Author/MSE)

Artificial neural networks (ANN), part of artificial intelligence, are discussed. Such networks are fed sample cases (training sets), learn how to recognize patterns in the sample data, and use this experience in handling new cases. Two cognitive roles for ANNs (intelligent filters and spreading, associative memories) are examined. Prototypes…

A discussion of authoring system technology is based on a review of 80 products. Alternative authoring approaches are described; assumptions underlying development of authoring systems and their use are examined; selection procedures and criteria sensitive to varied needs are suggested; and trends in software development, evaluation, marketing,…

Artificial intelligence techniques available for generating explanations for teaching purposes are surveyed, and the way in which they are combined in a computer program that provides explanations is described. The program responds to questions in the physical sciences. Potential contributions of this technology to computer-based education are…

Trends in the use of visualization (computer graphics) for instructional purposes are analyzed in three segments: (1) current classroom activities; (2) technically possible but not prevalent classroom activities; and (3) the future classroom. The discussion draws on University of Iowa efforts, national curricular innovations, and presentations and…

The shift from limited-capacity personal computers to powerful workstation technology offers an environment for writing instruction that allows networking, simultaneous performance of many tasks, and tools for designing custom lessons and individual applications. At Allegheny College (Pennsylvania), a first-year writing course is supported…
