Virtual experiments are beneficial and effective learning activities providing the opportunity to investigate the relationship between the experimental findings and the theories. There exist several advantages of using virtual experiments, including, among other things: 7/24 availability, opportunity of unlimited iterations, and working with an…

This exploratory study examined the influence of different virtual manipulative (VM) types on the nature of student pairs' techno-mathematical discourse (TMD). Three fifth-grade student pairs participated in 9 sessions of mathematics instruction using VMs. The study compared three VM types: linked, pictorial, and tutorial. Students' levels of…

Science educators and school administrators are reexamining the educational value of animal dissection in the nation's schools and are focusing on simulation as an instructional alternative. One implication of the debate is that simulations can lead to equivalent learning to hands-on dissection. The second implication is whether dissection is…

The dual purpose of this article is to provide a synthesis of the findings related to the use of computer simulations in physics education and to present implications for teachers and researchers in science education. We try to establish a conceptual framework for the utilization of computer simulations as a tool for learning and instruction in…

Describes a study conducted in undergraduate science classes in Singapore using computer modeling and simulation. Reports that the use of computer models and simulations proved to be valuable in explaining many aspects of science. Students reported that three-dimensional images helped them in their understanding. Contains 22 references.…

Covers research conducted within the past 10 years on the topic of using computer models and simulations to aid science instruction at the precollege level. The research is categorized into three main areas: (1) students running preprogrammed simulations; (2) students creating dynamic models using modeling environments; and (3) students using…

The intent of this study was to investigate the impact of introducing computerized means, mainly simulation and the Internet, on teaching and learning electronics in Israeli high schools. Computers in electronics studies are, at the same time, part of the subject matter learned and a means for teaching and learning. Data were collected through…

Suggests the use of computer simulation of continuous systems as a problem solving approach to computer languages. Outlines the procedures that the system dynamics approach employs in computer simulations. Explains the advantages of the special purpose language, DYNAMO. (ML)

Reports on a process which allows active study of mutating the characteristics of a population of organisms. States that the program, written in C, should run on a MS/DOS system with 640K; CGA is required for graphics output. Describes implementation procedures and two examples using the program. (RT)

Describes a computer program, "Activation Energy," which is designed for use in physical chemistry classes and can be modified for kinetic experiments. Provides suggestions for instruction, sample program listings, and information on the availability of the program package. (ML)

Describes the use of simulation to introduce the bootstrapping technique of creating confidence intervals for the mean, median, and variance. These bootstrap confidence intervals are compared to the traditional confidence intervals for the purpose of analyzing accuracy of the technique. A Minitab program to produce confidence intervals is…

Describes a simulation done by students in a Year 4 undergraduate physics laboratory course on pulse technology. The course objective was to provide students with experience in computation pulsed electrical circuits and in comparing the computation with experiments. Results showed that the microcomputer simulated experiments made for a more…

The results of a simulation model of a queuing system are reported. Use in an introductory quantitative analysis course to enhance students' computer and quantitative modeling knowledge is described. (CW)

Discusses a computer simulation to teach logic design using a Macintosh computer which allows circuits to be built piece by piece. Describes features of the simulation and presents several schematics drawn by the software. (MVL)

Abstracts six conference papers from the ISRAEL Association for Computers in Education. Included topics are spreadsheets for problem solving, concept acquisition with microcomputers, numerical mathematics, learning math as a science, studying polygons with LOGO, and a growth curve simulation of microorganisms.
