Standard maximum likeliheed estimation was compared using two forms of robust estimation, BIWEIGHT (based on Tukey's Biweight) and AMTJACK (AMT-Robustified Jackknife), and Rasch model person analysis. The two procedures recovered the generating parameters, but Rasch person analysis also helped to identify the nature of a response disturbance. (GDC)

Describes the style of design of computer simulations developed by Computer Assisted Teaching Unit at Queen Mary College with reference to user interface, input and initialization, input data vetting, effective display screen use, graphical results presentation, and need for hard copy. Procedures and problems relating to academic involvement are…

The design and use of a simple computer model which simulates a hillslope hydrology is described in a teaching context. The model shows a relatively complex environmental system can be constructed on the basis of a simple but realistic theory, thus allowing students to simulate the hydrological response of real hillslopes. (Author/TRS)

Describes three microcomputer programs that allow geology students to deform two-dimensional images on a computer screen and then to measure changes in angular relationships. Two of the programs simulate pure and simple shear and the third simulates variations in shear strain that occur in shear zones. (ML)

Research on intelligent tutoring systems is discussed from the point of view of providing moment-by-moment adaptation of content and form of instruction to the changing cognitive needs of individual learners. Implications of this goal for cognitive diagnosis, subject matter analysis, teaching tactics, and teaching strategies are analyzed. (Author)

This collection of articles includes an examination of word-processing software; project management software; new expert systems that turn microcomputers into logical, well-informed consultants; simulated negotiation software; telephone management systems; and the physical design of an efficient microcomputer work space. (MBR)

Describes the field evaluation process used to assess the validity, effectiveness, and efficiency of an interactive microcomputer simulation program designed for teachers and student teachers preparing to work with emotionally or behaviorally handicapped elementary school-age children. Results indicate the simulation was judged to be useful. (MBR)

Explores classroom microcomputer applications in elementary and secondary social studies. The utility of drill and practice and tutorial programs is reviewed; computer spreadsheets to project election tallies and databases for use in analyzing voter data are described; and economics and election simulations are compared. (MBR)

Reports results of studies with an unsupervised learning paradigm called competitive learning which is examined using computer simulation and formal analysis. When competitive learning is applied to parallel networks of neuron-like elements, many potentially useful learning tasks can be accomplished. (Author)

Describes: (1) an interactive computer simulation for a science fair display of chromatography inks; (2) analytical chemistry programs; (3) microcomputer-assisted drills in organic synthesis; (4) programs for conformation analysis of ethane and butane; (5) MOLPIX--a program for generating and displaying molecular structures; and (6) chemical…

Reviews author's opinions of the evaluation process as applied to microcomputer applications in elementary and secondary classrooms and discusses additional specific evaluation issues that need to be considered, i.e., motivational value, computer simulations, and social interaction among students and teachers and students and peers. (23…

Describes a video monitoring technique for detailed analysis of student use of computer-based learning programs which produces a synchronized record of computer output and student use; a study concerned with developing computer-based learning programs in chemistry which utilizes the technique; and advantages and disadvantages of the technique.…

Demonstrates how "School Planner," a menu-driven educational facility cost simulation program, is used for showing the changes in space and cost requirements, given varying assumptions about such factors as number of pupils, class size, number of classes per week, and proportion of space used for instruction. (MLF)

Alternatives to traditional, large-class lecturing are discussed. They include using canned lectures, demonstrations and lecture experiments, computer simulations, problem-solving strategies, breaks during lectures, and movies. Moving out of large classrooms to laboratories and resource rooms (or giving an examination) is also suggested. (JN)

Describes RESTSIM, an interactive computer simulation program for graduate and upper-level undergraduate management, marketing, and retailing courses, which introduces naive users to simulation as a decision support technique, and provides a vehicle for studying various statistical procedures for evaluating simulation output.
