The use of concept maps, Vee diagrams, flow charts, and productive questions to increase student understanding of laboratory exercises and to improve student attitudes toward lab classes is discussed. Examples of each are provided. Student responses to these teaching methods are described. (CW)

Describes methods for teaching mechanics. Concepts included are force, inertial frames, and rotation. Emphasizes how to feel or observe them. (YP)

Reports on a study, Science for All Americans, by the AAAS. Notes this study is the first of three phases in Project 2061. Recommends science teaching should focus on connections rather than boundaries between traditional academic disciplines and should emphasize ideas and thinking rather than specialized vocabulary and memorized procedures. (MVL)

Describes science activities which were adapted from a teacher's guide entitled "For Spacious Skies" and contains resources for interdisciplinary weather studies. Includes studying properties of air, gravity, cloud movement, humidity, tornadoes, and weather instruments. (RT)

"Spreadsheets in Physical Chemistry" contains reviewed and classroom tested Lotus 1-2-3 and SuperCalc IV templates and handouts designed for use in physical chemistry courses. The 21 templates keyed to Atkins' physical chemistry textbook, the 7 numerical methods templates, and the 10 simulation templates are discussed. (MVL)

Presents three dimensional models of biological pathways for the following cycles: carbon, nitrogen, sulfur, and a combination of the three. Discusses steps involved in each cycle and breaks each cycle into trophic and environmental regions. (MVL)

The main advantage of using these concepts lies in the reduction of algebraic work involved in solving certain dynamics problems. A brief analytical treatment of the acceleration center and a description of a virtual work principle for equipollent systems in the kinetics of rigid bodies are provided. (MVL)

Provided is a unit which relates the fulcrum of a lever system and the mean of a distribution of scores. The objective, rationale, two student laboratories, and an evaluation system are outlined. Content background on statistics is offered. (MVL)

Investigates the development of dynamics concepts with one group aged 12-14, and other group aged 14-16. Collects data from Assessment of Performance in Science tasks, Piagetian tasks, and classroom science curriculum. Discusses the interaction of cognitive development and classroom experience in the development of concepts. (Author/YP)

Describes 10 steps for developing a diagnostic test of students' misconceptions and the use of two tests in chemistry (covalent bonding and structure) and in biology (photosynthesis and respiration in plants). Discusses the results and some implications for teaching science. (YP)

Notes the remarkable success of the astronomy component of the National Curriculum in England and Wales. Presents findings of a survey of children's astronomical beliefs, which are consistent with constructivist theory, and proposes the value of children's astronomy learning. Argues that a 1995 revision in the National Curriculum, which would…

Describes an introductory biology course designed to enhanced the science learning of elementary education majors. A consideration of students' learning styles and interests combined with a belief that science academic talent is not a selective process, resulted in a biology course that was academically challenging and enjoyable for students. (ZWH)

Diverts from the traditional approach to teaching ecology and moves toward a more interdisciplinary approach by engaging students in a field trip to the Rocky Mountains. Using examples and insights, the author describes and identifies opportunities for promoting knowledge, understanding, and awareness of the environment and its surroundings. (ZWH)

Includes book reviews of science trade books written in Spanish from the following categories: (1) Animals, (2) Encyclopedic Series, (3) Nature, and (4) Physical Science. (ZWH)

Describes a project that uses a computer and a dot matrix printer to simulate the holographic recording process of simple object structures. The process' four steps are (1) superposition of waves; (2) representing the superposition of a plane reference wave on the monitor screen; (3) photographic reduction of the images; and (4) reconstruction of…
