This manual was written as an aid to teaching assistants (TAs) who conduct the laboratory portions of life science courses at the University of Washington. In general, this manual does not present specific factual material. Rather, it offers suggestions on how to handle various teaching situations and provides a framework to use in many different…

The purpose of this brochure is to introduce teachers to the University of Hawaii's language laboratory facilities and services. Key features built into the laboratory are student cartridge decks and the dual-teacher console. The procedures and functions of the language laboratory are described in three major sections: (1) student facilities, (2)…

Described is an experiment used in an undergraduate biochemistry laboratory involving inducing rickets in chicks and correlating the disease to a reduction in vitamin D-dependent calcium binding protein. Techniques involved are hormone induction, protein isolation, and radioisotope methodology. (Author/DS)

A trainerless laboratory model wherein the trainer never attends is presented. The discussion includes the advantages and disadvantages of the model, evidence for its effectiveness, and implications for the future of training. (Author)

Describes the development of a laboratory training program with unusual promise for social change in the Dominican Republic. (AN)

Discusses ways to cut rising energy costs within university laboratories by using heat recovery systems and variable volume exhaust hood systems. Explores the implementation of broad-based, sustainable laboratory classroom design concepts. (GR)

A number of laboratory exercises for the organic chemistry curriculum that emphasize enantioselective synthesis of the aldol condensation which involves the proline-catalyzed condensation between acetone and isobutyraldehyde are explored. The experiment illustrates some of the trade-offs involved in green chemistry like the use of acetone in large…

The creation of a simple, low-cost lock-in amplifier (LIA) suitable for use in the chemistry teaching laboratory is described. The use of integrated circuits and few components are necessary to adequately accomplish lock-in amplification limited the total cost of construction to under US$100.

We present a simple computer-based laboratory experiment for evaluating absolute zero in degrees Celsius, which can be performed in college and undergraduate physical sciences laboratory courses. With a computer, absolute zero apparatus can help demonstrators or students to observe the relationship between temperature and pressure and use…

A nonlinear aspect of the acousto-optic interaction that is analogous to multi-photon absorption is discussed. An experiment is described in which the second-order acousto-optically scattered intensity is measured and found to scale with the square of the acoustic intensity. This experiment using a commercially available acousto-optic modulator is…
