A computer-based replacement for an electronics laboratory experiment was created and tested on second-year undergraduate students in the Department of Mechanical Engineering at the University of Southampton (England). Responses, assessed by questionnaire, showed that computer-assisted learning techniques provide a viable means for teaching…

Describes a computer model characterizing the balance of soil-plant Nitrogen that allows students to see the likely consequences of different biological and weather-related parameters. Proposes three uses for the model: (1) orienting beginning students to understand the soil Nitrogen cycle; (2) providing information for advanced students; and (3)…

Describes a study that examined the accuracy and type of preservice teacher feedback to computer-simulated pupils. Accurate and inaccurate feedback when focusing on the accomplishments and deficiencies of the simulated pupils is examined, and patterns linking teachers' assessment of pupil performance with feedback during lesson interactions are…

Describes the use of Smalltalk-80, a French programing language, to teach young children to program effectively using object-oriented concepts. Learning processes involving problem solving and programing are examined, the object-oriented environment is discussed, teacher training is described, and future work is suggested.

Elementary computer teacher describes a summer program in which fifth graders cooperatively created a computer-based city planning unit. Students strengthened math, writing, technology, and problem-solving skills as they organized and used a bank, purchased property, proposed and designed buildings, and assembled the futuristic city using a…

Considers the role of educational technology in two views of the school reform movement: one that demands more from the existing educational system, and one that calls for restructuring of the existing system. The effectiveness of technology is addressed, models for technology use are described, and technology and constructivism are discussed. (31…

An experimental class in introductory statistics (n=40) using simulation software at American University was compared to a traditionally taught control group (n=36) with respect to achievement and accrued beliefs about the benefits of the simulations. Results indicate significantly higher achievement scores for the experimental class with about…

Students' views of science as static, mixed, and dynamic are characterized. The relationship between views of science and acquisition of integrated understanding of thermodynamics is examined. Students with dynamic views acquired more integrated understanding than those with static views. Data were collected from 153 middle school students who…

Effects of the following variables on performance of computerized adaptive testing (CAT) procedures for the partial credit model (PCM) were studied: (1) stopping rule for terminating CAT; (2) item pool size; and (3) distribution of item difficulties. Implications of findings for CAT systems based on the PCM are discussed. (SLD)

Provided are three program listings which may be used to illustrate this fractal figure. Extensions of these algorithms and their use in the study of chaos and fractals are suggested. (CW)

Describes the development of a simulation-based intelligent tutoring system for nurses working in a surgical intensive care unit. Highlights include situative learning theories and models of instruction, modeling expertise, complex decision making, linking theories of learning to the design of computer-based learning environments, cognitive task…

Describes Internet-based online interactive role-playing simulations of current political events that were developed at Macquarie University (Australia) to be used with Internet partners around the world. Discusses the use of e-mail, teleconferences, and evaluation of the simulations. (LRW)

Investigates the effects of preservice teachers working in paired-learning conditions versus working independently on a computer-based tutorial/simulation designed to teach users about an electronic-mail system. Findings support previous research on the positive effects of paired learning using computer-based instruction designed for individual…

Describes the development and use of two computer simulations for investigating systems thinking and environmental problem-solving in children (n=92). Finds that older children outperformed younger children, who tended to exhibit magical thinking. Suggests that seemingly isomorphic environmental problems may not be interpreted as such by children.…

NASA research into plant-based regenerative systems for sustaining colonies in space provides the core content for the Classroom of the Future (COTF), a NASA sponsored project that transfers research on space exploration to high school biology classrooms. This article describes and evaluates BioBlast (Better Learning through Adventure, Simulations…
