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…

A common problem in many schools is the lack of equipment and materials in their science laboratories due to both limited budget available to the school and high maintenance cost of the lab. The latest technological advancements provide great opportunities for schools to go over the budget and cost issues by using 3D virtual learning environments…

The main aim of this study was to examine how a group of elementary students perceived their engagement in a project-based science intervention investigating the water quality of a local lake. The students collaborated with a scientist to conduct various experiments and used handheld computers to collect and analyze data in order to examine the…

This study examined the influence of virtual manipulatives on different achievement groups during a teaching experiment in four fifth-grade classrooms. During a two-week unit focusing on two rational number concepts (fraction equivalence and fraction addition with unlike denominators) one low achieving, two average achieving, and one high…

Reports on a study into the effectiveness of implementing an interactive videodisc science lesson on titration into a high school science program. Describes the titration lesson and the equipment used in two chemistry classes. Results were generated from achievement and attitude instruments, along with observational data. (TW)

Reviews emerging applications of microcomputers and hypermedia to assessment. Use consists mainly of computerized test administration of multiple-choice tests drawn from item banks. Significant advantages are possible in several areas including immediate feedback to students, formative evaluation with remediation possibilities, and monitoring…

Presents results of a study that examines the development and use of computer simulations for high school science instruction and for integrated laboratory and computerized tests that are part of the biology matriculation examination in Israel. Eleven implications for teaching are presented. (MDH)
