Compares current science education reform efforts with those of the 1960s to enhance student learning. Discusses how an "alternative models" view of scientific explanation can contribute to reforms of course goals, social aspects of science learning, instructional practices, and roles for technology. Contains 50 references. (ZWH)

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…

Reports on the results of a conference of leaders in science education research held at the University of California, Berkeley, January 16-20, 1986. Describes the themes that emerged from the disucssions and makes four recommendations intended to encourage the development of an integrated research base in science education. (TW)

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)

Research on the development of ability to control variables during adolescence is reviewed. The first section discusses studies by Piaget and his collaborators, replications of Piaget's studies, and related studies by other investigators. Factors which influence performance on controlling variables tasks are delineated; the existence of Piaget's…

A developmental investigation of the ability to control variables was conducted. One or two logically similar physics problems were individually administered to 120 subjects age 12 to 14. The problems involved either familiar or unfamiliar variables. Each problem was presented in three different informational formats. Success on the problems in…

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)

Presented is a study of a science program for upper elementary and middle school children encouraging the development of logical thinking skills, describing variables, interpreting and criticizing experiments, and understanding experiment design. To provide a basis for the program, the students suggested projects to be done and developed…

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)

Reports on a two-year study designed to investigate how a Web-Based Integrated Science Environment (WISE) project called "Plants in Space" featuring classroom investigations enabled 5th grade students to increase their understanding of plant growth and development. Investigates two versions of the curriculum and considers how understanding of the…

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)

Gives historical account of research and practices associated with precollege science laboratories. Described three social contexts of research on science laboratories: separation, interaction, and partnership. Argues that more partnerships are needed to continue improvement to the science laboratory, suggesting that future partnerships will…

Reports a study undertaken to determine the effect of the Science Curriculum Improvement Study (SCIS) on logical thinking. Evidence of logical thinking was measured as the ability to explain compensating variables that occurred in a cart experiment presented on silent 16 mm film. (GS)
