In the activity described here students build mazes, then time fellow students as they "run" the mazes. They then graph the results to determine a learning curve. (SD)

Describes applications of mechanical principles based on the theory of flight. Includes a discussion of aerofoils and lift, aircraft structures, aircraft performance, and laboratory experiments. (GS)

Describes a general chemistry level kinetics experiment requiring three 3-hour laboratory periods. Data analyses can be accomplished with graphical techniques or a non-linear least squares computer program. (MLH)

Describes an experiment in which general and physical chemistry students can determine the heat of vaporization of a volatile substance from experimental laboratory data using timesharing techniques. (MLH)

Describes an organic chemistry experiment in which seven possible mechanisms for the isomerization reaction are tested with simple sense observations and melting point determinations. (MLH)

Describes the process for determination of the constants from data obtained with a hydrogen-deuterium light source and Ebert plane grating spectrograph. (Author/CP)

Includes a discussion of the structure of some molecules and the design of an experiment to replace CHEM Study Experiment 7. (GS)

Recommends practices to be followed in the preparation of lecture demonstration video-tapes. (CP)

Methods of motivating junior high school students in the study of mathematics includes use of contemporary materials, introducing topics related to history, applications, and recreations, and providing for guessing, laboratory experiences, and discovery. (SD)

Describes material modified from the Nuffield advanced chemistry course to make it meaningful and relevant to pupils in the middle school. Discusses a series of simple experiments on apple browning and summarizes the browning process and its control. (Author/GS)

Discusses a system for evaluating student performance in the language laboratory, grading for comprehension and correctness, with four categories: complete, limited, severely limited, unsatisfactory. Evaluation of laboratory performance is more objective, being based on what has been taught and learned under stable conditions. (Text is in German.)…
