Reported is a summary and review of over 300 research papers published in 1987. The review is organized into four sections: (1) "Learners and Learning"; (2) "Teachers and Teaching"; (3) "Curriculum and Instruction"; and (4) "Context and Settings." (YP)

Uses clinical cases taken from the medical or dental literature for examination of understanding certain aspects of the dental profession. Formulates questions derived from data presented in the case or attempts to present broad principles. Includes 15 example test questions. (MVL)

Notes two uses of computer spreadsheets in the chemistry classroom. Discusses the general use of the spreadsheet to easily provide changing parameters of equations and then replotting the results on the screen. Presents a molecular orbital spreadsheet calculation of the LCAO-MO approach. Supplies representative printouts and graphs. (MVL)

Treats the development of general stereochemical principles in historical fashion. Discusses work by Pasteur, van't Hoff, and Le Bel. Considers sugars by configuration, anomeric forms, ring forms, and conformational isomers. Presents numerous diagrams and thorough explanations. (MVL)

Presents an exercise to get students more intimately involved in the three dimensional nature of basic units by constructing models. Uses balsa wood, glue, sandpaper, and a square. Studies seven crystals: cubic, hexagonal, monoclinic, orthorhombic, rhombohedral, tetragonal, and triclinic. Plans are available for a Macintosh computer. (MVL)

Describes the Systems Thinking and Curriculum Innovation (STACI) Project, which is examining the impact of a technology-based curriculum innovation on teaching and learning outcomes in high school science and social studies. Systems thinking is discussed, simulation-modeling software is described, and implications for technology in educational…

Describes a science experiment in which the heartbeats of mammals can be counted and graphed as measurable data by the computer. Provides information on materials needed, pre-lab activity worksheet, and follow-up activities. (RT)

Outlines a one day chemistry seminar which is part of the Elementary Science Fellows Programs at the Wisconsin Regional Staff Development Center. Lists the topics of the program and some activities that were used. Discusses the status of the program. (MVL)

Reports that young children in the pedestrian accident prone age range of four-eight years hold a variety of naive conceptions regarding speed. Proposes a primary science unit using a conceptual change approach. (MVL)

Outlines a lesson on the study of rocks including classification, identification, and observation techniques. Provides a listing of activities which integrate rocks with art, mathematics, and language arts. (RT)

Discusses a new Australian Academy of Science secondary chemistry textbook that provides a more interesting, enjoyable, and understandable base to a wider spread of students. Notes that rigor is maintained for use in college prep courses. Lists context for change, guiding philosophies, and the table of contents. (MVL)

Discusses the use of robotics in the analytical chemistry laboratory. Suggests using a modular setup to best use robots and laboratory space. Proposes a sample preparation system which can perform aliquot measurement, dilution, mixing, separation, and sample transfer. Recognizes attributes and shortcomings. (ML)

Reports two electrochemical demonstrations. Uses a hydrogen-oxygen fuel cell to power a clock. Includes description of methods and materials. Investigates the "potato clock" used with different fruits. Lists emf and current for various fruit and electrode combinations. (ML)

Describes the Assessment of Performance Unit (APU) Science project. Discusses the findings including perceptions of problems, procedural understanding, control of variables, and measurement strategies. Suggests a change from traditional learning strategies to more student-centered ones. (YP)
