To effectively integrate information technology into classroom activities, preservice teachers must know a variety of computer concepts. Presents a model used to instruct preservice teachers in programming activities based on simulation and interactive learning. Students gained an understanding of computer roles, their programming, and…

Describes several of the labs developed by Project CLEA (Contemporary Laboratory Experiences in Astronomy). The computer labs cover simulated spectrometer use, investigating the moons of Jupiter, radar measurements, energy flow out of the sun, classifying stellar spectra, photoelectric photometry, Doppler effect, eclipsing binary stars, and lunar…

Describes an interactive computer program that simulates the physiological response to graded exercise in healthy individuals. The program presents high-resolution graphic data in a form comparable to that of a chart recorder display. Data are derived from an empirical model that allows users to select parameters to investigate. The program was…

Discussion of computer-based simulations focuses on the development of a coaching agent as an alternative to traditional feedback for a multimedia simulation that will help change training from traditional instructor-led courses to learn-by-doing simulations for point-of-need training. The limitations of traditional feedback are examined. (LRW)

Discusses computer games being used for education and training. Describes educational computer games; simulation games in military training; adventure games in business and corporate environments; interface design; pedagogical knowledge; domain expertise; and future possibilities. (LRW)

Cognitive simulations are runnable computer programs for modeling human cognitive activities. A case study is reported where expert systems were used as a formalism for modeling metacognitive processes in a seminar. Building cognitive simulations engages intensive introspection, ownership and meaning making in learners who build them. (Author/AEF)

Reports the results of research that examined ways in which a computer simulation of a banking workplace influenced high schoolstudents' general knowledge and understanding about the world of work. Results indicated students who used the simulation had a broader sense of work and had more subtle understandings of current trade-offs than did…

Considers whether critical thinking can be trained with computer-based instruction. Reviews literature on the effects of cognitive tools, collaborative computer-supported environments, computer simulations, and logic software on critical thinking, and reports on two experimental studies at the University of Erfurt that instructed undergraduates in…

A logistic regression model for characterizing differential item functioning (DIF) between two groups is presented. A distinction is drawn between uniform and nonuniform DIF in terms of model parameters. A statistic for testing the hypotheses of no DIF is developed, and simulation studies compare it with the Mantel-Haenszel procedure. (Author/TJH)

Notes that not having anything to say is a major hurdle in the writing process at the middle school level. Describes two common classroom experiences, based on the software programs "GeoWorld" and "Food for Thought," that enable all students to acquire and share information together. (RS)

Describes a computer simulation designed to examine secondary school students' strategies in solving a physics problem involving the velocity of a rocket. Students' beliefs about dynamics are discussed, use of the LOGO programing language to explore the idea of velocity is described, and ways in which simulations can support teachers' diagnostic…

Describes an intelligent tutoring system (ITS) that demonstrates how intelligent feedback can enhance conventional simulation-based training. An explanation is given of the Intelligent Conduct of Fire Trainer (INCOFT), which was designed to provide training exercises for soldiers operating the PATRIOT missile system, and its implications for…

Discusses making a computer-simulated rainbow using principles of physics, such as reflection and refraction. Provides BASIC program for the simulation. Appends a program illustrating the effects of dispersion of the colors. (YP)

This study showed that the Elementary Perceiver and Memorizer (EPAM) can explain letter recognition phenomena earlier simulated by the connectionist Interactive Activation Model of word perception. EAPM, a model of learning and recognition in the form of a computer program, has previously explained many aspects of learning and perception. (TJH)

Discusses how a spreadsheet might be used in an introductory physics laboratory. Describes three categories of spreadsheet uses, advantages of spreadsheet, layout, accuracy, and modifications. Gives an example of the variable mass rocket problem with typical display. (YP)
