Highlights the need to make the undergraduate physics laboratory more exciting and commensurate with the time assigned for it in the curriculum. Suggests establishing a model undergraduate physics laboratory at one place then reproducing it in five places for a massive reorientation program for teachers. Contains brief outlines of 30 experiments…

Describes four models: The Authoring Cycle, a whole language approach that reflects the inquiry process; I-Search, an approach to research that uses the power of student interests; Cultural Celebration, using local heritage topics; and Science Lab Report, for the composition of a lab report. (LRW)

Describes a research and development project aiming to help develop secondary students' abilities to understand biotechnology/genetic engineering. Focuses on an exemplary true-to-life experiment, planned and executed by students in grade 8, that involves external experts and uses an industrial research laboratory for solving genuine questions.…

Describes a project involving the development, application, and evaluation of a virtual chemistry laboratory (VCL) that involves basic step-by-step laboratory procedures and simulates real laboratory activities. Presents the program in terms of tutorial, VCL, and evaluation, and a section that allows instructors to create their own tests. (KHR)

The effectiveness of a demonstration-data interpretation exercise was evaluated with first year medical students (N=124) at the University of Malaya. Results suggested that the exercise achieved more effective short-term learning than conventional laboratory exercises, but a need was found for materials to help students link theory to practical…

Examined are some of the types of two-dimensional spectra. Their application to nuclear magnetic resonance for the elucidation of molecular structure is discussed. Included are J spectroscopy, H-H correlation spectroscopy, heteronuclear correlation spectroscopy, carbon-carbon correlation, nuclear Overhauser effect correlation, experimental…

Background information, laboratory procedures, and a discussion of the results of an experiment designed to investigate the difference in energy gained from the aerobic and anaerobic oxidation of glucose are presented. Sample experimental and calculated data are included. (CW)

Described are the composition, design, administration, and evaluation of practical examinations. A table of the composition of biochemical unknowns for analysis in practical examinations is included. (CW)

An activity is described in which students learn modeling skills by creating concrete models with familiar objects. Teaching methods, materials, procedures, and outcomes are discussed. (CW)

Activity suggestions for the months of September and October are provided in a calendar format. In addition, two activity sheets, which provide detailed information for studying the moon and the alphabet including materials, and procedures are provided. (CW)

Described is an activity in which the transmission of disease is simulated by the students in the classroom using common solutions. Discussed are materials, preparation, procedures, and questions for classroom discussion. (CW)

Described is an experiment which illustrates valence isomerization, the trapping of a reactive intermediate and retrosynthetic analysis applied to the Diels-Alder reaction. Included is a background discussion, experimental procedures, and a discussion of the analysis. (CW)

Two exercises on the dispersal of tree seeds by the wind are presented. Procedures, equipment, and analysis for the still air and wind dispersal activities are described. Nineteen references are listed. (CW)

The construction of a wooden model of the musculoskeletal system which can be used to investigate the physical properties of muscles without sacrificing laboratory animals is presented. Six activities are included with answers. Additional activities are suggested. (CW)

Uses reversible electrochemical cells near equilibrium to study basic thermodynamic concepts such as maximum work and free energy. Selects sealed, miniature, commercial cells to obtain accurate measurement of enthalpy, entropy, and Gibbs free energy. (MVL)
