Described is the importance of the cognitive level of science pupils, cognitive demands of the curriculum, and the social/cultural context within which curricula are planned. Emphasized is the historical division between planning and implementation. Suggestions for improvement are provided. (CW)

Investigated were gender-related differences in the relationship between the development of formal reasoning skills and learning interests during the early adolescent stage. Results indicated that adolescent boys appeared to develop patterns of formal reasoning before their female classmates. Differences in subject preferences were also found. (CW)

Reviewed are two computer software packages: "Super Solvers Midnight Rescue!" a problem-solving program for IBM PCs; and "Interactive Physics," a simulation program for the Macintosh computer. The functions of the package are discussed including strengths and weaknesses and teaching suggestions. (CW)

Reviewed are three computer software packages including "Martin Luther King, Jr.: Instant Replay of History,""Weeds to Trees," and "The New Print Shop, School Edition." Discussed are hardware requirements, costs, grade levels, availability, emphasis, strengths, and weaknesses. (CW)

Described are the results of a spatial skills test designed to assess processing from 2-D to 3-D, 3-D to 2-D, and orientation. Results indicated that different aspects of spatial ability did not develop at the same rate, and the 3-D to 2-D skill took the longest to develop. (CW)

The Learning in Science Project (Energy) was designed to investigate teaching and learning about the energy concepts of New Zealand elementary and secondary students. Discussed are aspects of an approach to teaching energy to low ability students in physics. (YP)

Proposed is an activity designed to teach the similarities and differences between artistic and scientific vision. Objectives, materials, procedures and follow-up activities are listed. Preliminary activities in physical science and earth science are suggested. (CW)

Activities that may take place in a greenhouse are discussed. Included are learning how to grow plants, plant growth, soil, vegetative reproduction, and plant habitat adaptations. Materials, procedures, and results are presented for the activities. (CW)

Described is an introductory experiment that allows students to directly observe and measure the linear energy transfer in matter. Illustrated are the experimental setup including the radioactive source, electronic equipment, and the detector; measurement and calculations; and the results. (CW)

Reviewed are four videotapes for use in biology classrooms. Included are "The Biochemical Basis of Biology. Part 2--DNA and Protein Synthesis,""The Rocky Shores,""A Visit to the Rocky Shores," and "Our Immune System." Described are the content, cost, and availability of each video. (CW)

Provides reviews of courseware entitled: "Mystery Matter," which is a series that supplements the basic inquiry process; "Jumping Math Flash," which is an arcade-game program with arithmetic problems; and "Quest for Files: Science Rocks and Minerals The Upper Crust," which is a database program for earth science.…

Notes the careful observation of chemical reactivity phenomena has been and should be an important part of the general chemistry laboratory curriculum. Stresses reduction of experimental scale will help to ensure, in times of rampant chemophobia, that it remains so. Provides several examples of the methodology. (MVL)

Reports the function of the Reactivity Network which is to translate reactivity data from the primary literature into some 30 reviews for high school teachers and curriculum developers and to disseminate that information nationwide. Discusses a needs assessment done for the project. (MVL)

Provides an eclectic annotated bibliography of secondary sources for inorganic reactivity information of interest to reactivity network review authors and to anyone seeking information about simple inorganic reactions in order to develop experiments and demonstrations. Gives 119 sources. (MVL)

Discusses the necessities of regional resource centers for K-12 levels. Provides some examples of centers and describes their activities. Suggests three conditions for the success of a center. (YP)
