Powerful online visualizations can make unobservable scientific phenomena visible and improve student understanding. Instead, they often confuse or mislead students. To clarify the impact of molecular visualizations for middle school students we explored three design variations implemented in a Web-based Inquiry Science Environment (WISE) unit on…

This book shares the lessons learned by a large community of educational researchers and science teachers as they designed, developed, and investigated a new technology-enhanced learning environment known as WISE: The Web-Based Inquiry Science Environment. WISE offers a collection of free, customizable curriculum projects on topics central to the…

Presented is a discussion on how an evaluator can function effectively in a Science and Technology Center, using an evaluation model on experience in evaluating exhibits at the Lawrence Hall of Science over a six-year period. The approach in this paper is described for four areas: (1) evaluation of currently available exhibits and programs; (2)…

Presented is the argument that museums currently have a greater need for formative than for summative evaluation. Areas of formative evaluation that are of primary concern are also discussed. (Author/SA)

Investigated divergence in science performance between U.S. and Japanese elementary students. Data from observations and analysis of science lessons in Japanese schools highlighted eight science activity structures and a rough order of occurrence in typical science lessons. These activity structures support a coherent inquiry process, and they may…

Reported is a study to investigate the effects of a free-choice program on children's ability to interpret experiments, design simple investigations, and recognize variables that could affect the outcome of observed events. (Author/SA)

Describes the use of a microcomputer-based laboratory (MBL) in teaching the concepts of heat and temperature to eighth grade students. Discusses the advantages of being able to instantly display the results of their experimentation with the use of temperature and light probes, and heat pulsors. (TW)

Investigated were children's reactions when allowed to choose their own apparatus and perform experiments with appropriate directions available. Few students invented their own experiments; most followed the available printed instructions. (SL)

Presented is a discussion on the value of science and technology centers in providing learning experiences for visitors. The discussion is not limited to science centers but includes applications possible to any museum interested in providing interactive experiences. (SA)

Examines (1) how students evaluate information obtained in the science laboratory; (2) the effects of use of microcomputer-based laboratory; and, (3) the effects of explicit instruction on critical evaluation skills. Discusses results in terms of students' propensity to accept incorrect graphs and in terms of the effect of the enhanced instruction…

Examines a free choice program and ways seventh graders choose their own activities in five science categories: (1) Mechanical; (2) Physics; (3) Chemistry; (4) Biology, and (5) Combinational. Results suggest that the challenge format for the activities allows students to practice what they have learned and consolidate their knowledge. (HM)

Three questions guided an evaluation of sixth and eighth grade science enrichment activities: (1) Does a free choice interactive program affect cognitive abilities? (2) Do students in a free choice program make predictable selections of activities based on their age, sex, or ability level? and (3) Are specific student choices associated with…
