This article draws on second language theory, particularly output theory as defined by Swain (1995), in order to conceptualise observations made in a computer-assisted language learning setting. It investigates second language output and learner behaviour within an electronic role-play setting, based on a subject-specific problem solving task and…

Public school teachers (N = 189) role-played as members of school councils making principal selection decisions by rating simulated candidates for principal vacancies. The independent variables were principal candidate job experience, candidate person characteristics, and teacher school level. The dependent variable was teacher rating of the job…

This paper presents Petri net software tool P3 that is developed for training purposes of the Architecture and organization of computers (AOC) course. The P3 has the following features: graphical modeling interface, interactive simulation by single and parallel (with previous conflict resolution) transition firing, two well-known Petri net…

In this paper we report upon the Virtual Economy (VE), an Internet simulation which operated for the first time in Spring 2000 involving students at Indiana University, USA and at Napier University, Edinburgh, UK. During 2001, the VE was extended to include participants from other institutions. The main thrust of the project was to encourage…

Many students doubt that statistical distributions are of practical value. Simulation makes it possible for students to tackle challenging, understandable projects that illustrate how distributions can be used to answer "what-if" questions of the type often posed by analysts. Course materials that have been developed over two years of classroom…

One hundred and twenty-seven undergraduate business majors at a regional northwestern university completed a series of hypothetical choice tasks in which they were asked to choose between two courses that varied with respect to the instructor's course evaluations, grading leniency, the course's worth/usefulness, and the assigned workload. Data…

In this article, the author discusses the use in policy analysis of models that incorporate uncertainty. He believes that all models should consider incorporating uncertainty, but that at the same time it is important to understand that sampling variability is not usually the dominant driver of uncertainty in policy analyses. He also argues that…

Aviation concepts, including forces acting on an airplane, navigation, correct aircraft terminology, and general aviation vocabulary, are often part of a comprehensive fifth-grade aviation curriculum. But in one school district, students also learned about flying planes and even trained in a flight simulator. This article describes how industry…

What is meant when people say that "learning environments are increasingly complex"? What is known about the cognitive processing that occurs during complex learning? How can educators provide effective instructional support for students who must learn and apply complex knowledge? These questions, and related issues, have fascinated educators and…

Despite recent British government moves to equip all Primary Schools with fast broadband connections to the Internet, it would seem that many schools as yet make little use of the increased capacity this affords other than to incorporate more and more rich multimedia in the form of interactive games or animated presentations to illustrate…

This comprehensive resource is an invaluable aid for adding a global dimension to students' understanding of American history. It includes a wide range of materials from scholarly articles and reports to original syllabi and ready-to-use lesson plans to guide teachers in enlarging the frame of introductory American history courses to an…

This publication presents the following articles: (1) Advanced Technological Education (ATE) Develops Student Recruitment and Retention Strategies; (2) Marketer Advises Tech Educators Appeal to Teens' Emotions, Desires to Do Something Important; (3) Digital Bridge Academy Gets At-Risk Students on Paths to Knowledge-Based Careers; (4) Project…

A prototype simulation measure of the negotiating skill of interpersonal competence is described, and results of an initial validation study are reported. Of eight negotiating skills identified by the Secretary's Commission on Achieving Necessary Skills of the U.S. Department of Labor, two were the focus of the measure: proposing and examining…

A classroom study in two advanced Chinese language courses compared the effectiveness of two instructional strategies: (1) proficiency-based instruction through cooperative learning (Chinese 405) and (2) "prochievement," a hybrid, performance-based strategy derived from both proficiency and achievement approaches (Chinese 406). Subjects…

An interactive training model called SAVR (Safety in Construction Using Virtual Reality) was developed to train construction students, novice engineers, and construction workers to prevent falls from scaffolding. The model was implemented in a graphics supercomputer, the ONYX Reality Engine2. The SAVR model provides trainees with an immersive,…
