The problem-solving behaviors and genetics concepts employed by experts and novices during interaction with the computer simulation CATLAB, were examined. Thirteen subjects (3 experts and 10 novices) investigated a common hypothesis on a specific genetic trait during the computer activity. Using naturalistic research methods, general patterns of…

Describes software, hardware, and devices that were designed to provide students with an environment to experiment with basic ideas of mechanics, including nonlinear dynamics. Examines the behavior of a Lorenzian water wheel by comparing experimental data with theoretical results obtained from computer-based sensors. (MDH)

Described is the use of computer software, with and without guiding text, for a simulation that presents processes related to electric charges and electric forces underlying the electric-pendulum phenomenon. Included are methods for integrating this simulation with actual middle-school science class demonstration. (JJK)

The purpose of this study was to examine the effects of three instructional methods and conceptual systems orientation on achievement in a freshman general chemistry laboratory course. Traditional approach, learning cycle, and computer simulations are discussed. (KR)

Discusses visual style in instructional science materials; describes problems with science media, including too much print on a page or screen and inappropriate designs for children; and highlights new products that have good design style as well as good content, including books, computer simulations, videos, computer software, and microworlds.…

Business schools across the country are specializing in electronic commerce, in which teams of students create online businesses available on the Internet only to participating institutions. The courses offer students an opportunity to see how an online retailing business is conducted, including creating and maintaining Web sites, advertising…

Describes the development of a speech-activated multimedia system for foreign-language training. The model allows students to engage native speakers on CD-ROM in lengthy face-to-face dialogs using natural spoken language. (Author/VWL)

Examines mathematics problem solving in a computer software environment using graphical representations of the results of simulations with adolescent students. Discusses the strengths and limitations of inferring goals and plans, the use of verbal protocols, and ways for computer-based learning environments to scaffold acquisition of domain…

This theory-based article describes how data analysis tools, simulations, and modeling software, when used in the proper instructional contexts, provide young learners with rich intellectual environments for inquiry in science learning. Highlights include inquiry learning; abilities of learners; and the integration of technology within classroom…

Examines the importance of the instructional systems design (ISD) model in designing the presentation and content of technology-based learning (TBL) environments, especially for adult learners. Describes TBLs and their use in university and adult learning and discusses the most common presentation methods: drill and practice, tutorial, simulation,…

Reports on a pilot study that examined use by sixth-grade students in Costa Rica of a mathematical microworld written in LOGO. The investigation had three phases: (1) open exploration of the microworld; (2) group discussion and sharing of hypotheses; and (3) guided discovery and problem solving. (Contains 11 references.) (SLW)

Examines factors that should be considered in designing an independent study undergraduate library skills course using computer-assisted instruction based on experiences at the University of Minnesota, Saint Paul. Highlights include the use of HyperCard, revising modules, interaction, simulations, student attitudes, lack of instructor feedback,…

Describes a study of university students that investigated the effects of a variable unique to Internet-based learning, namely download delay of instructional materials. Discusses a simulated online teaching tool that measured the effects of download delay of images on test performance, time spent on the material, end-user satisfaction, and…

Simulation output analysis has received little attention comparing to modeling and programming in real-world simulation applications. This is further evidenced by our observation that students and beginners acquire neither adequate details of knowledge nor relevant experience of simulation output analysis in traditional classroom learning. With…

This study examines the effects of a teaching method using 3D virtual reality simulations on achievement and attitude toward science. An experiment was conducted with fifth-grade students (N = 41) to examine the effects of 3D simulations, designed to support inquiry-based science curriculum. An ANOVA analysis revealed that the 3D group scored…
