Discusses the lasting effects of the Science-Technology-Society movement. Cites the recommendations from Project 2061 as for learning goals, and suggests some changes for teaching arrangements. (YP)

The purpose of this study was to examine the home and school effects on science achievement of 12th-grade students (N=2,277) in Israel. Significant correlates of achievement included home environment, quantity of instruction, interest, and motivation. (IAH)

Discussed is the thermodynamic instability of organic peroxides. The process of autoxidation which results in peroxide formation is described. Precautions necessary to prevent autoxidation hazards associated with these reagents are suggested. (CW)

Describes the Second International Science Study. Analyzes several variables mitigating the interpretative power of the study, including different needs and agendas, cultural bias, equivalence of data, data analysis, student retention rates, comparability of target populations, and test validity. (YP)

Described is a Dutch thematics physics curriculum recently developed for the average academic secondary student. Discussed are the structure, contents of units, and systematic units of the curriculum. (CW)

Described are the rationale, methodology, and findings of seven case studies designed to investigate the teaching and learning strategies employed in science classes by exemplary teachers. Findings focused on management strategies, student understanding, student participation, and classroom environment. (CW)

Investigated were student problem-solving strategies in an attempt to develop a model of student performance. The problem-solving strategies used by 30 high school students were analyzed. Suggestions for improved instruction in solving genetics problems are provided. (CW)

Presented is a policy regarding vivisection, dissection, and other use of animals in biology classrooms. Alternative teaching techniques are stressed. The organizational responsibility regarding this issue is discussed. (CW)

Describes a secondary school visitation program by scientists in Australia. The program was designed to increase students' motivation related to science, especially physics. Discusses the effects of the program. (YP)

Described are five activities using crayons to demonstrate the rock cycle including weathering, erosion and sedimentation, and sedimentary, metamorphic, and igneous rock formation. Discussed are materials, procedures, and probable results. (CW)

Described is an exercise which examines the effect of reading aloud a technical passage of science material while the heart is monitored by a computer. The experimental setup, design, and data analysis are discussed. (CW)

Presented is one approach to the reform of earth science education. Discussed are conceptual themes, the role of elementary school science, the development of positive science attitudes, selection of topics and the role of the geologist. (CW)

Identifies and discusses the overlap between mathematics and physics at different educational levels. Presents some examples of the overlap and some suggestions for teachers. (YP)

Described is an approach that uses a computer spreadsheet program to calculate entropy change at constant temperature and pressure. The calculated values can be used in an associated graphing program. (CW)

The assembly and use of an Ostwald-type of viscometer from readily available materials is illustrated. Sample data and a schematic of the apparatus are provided. (CW)
