Offers challenging work at a higher level of technique than most students meet in elementary laboratory work. Uses a combined weight and volumetric sequence not shown in textbooks. Notes modern rapid balances help lower evaporation loss during weighings. Discusses the balance, weights, and buoyancy considerations. (MVL)

The importance of analyzing laboratory situations in a technical school special needs area is increasing rapidly. Such a system is essential for objectively analyzing the content of laboratories and describing the tasks performed there in a standardized and easily understood manner. The laboratory description can be easily used to provide program…

Uses a method which involves weighing out an amount of the appropriate weak acid or base and dissolving it in distilled water close to the final volume. Solution is then titrated with strong acid or base to give the desired pH. Provides three examples. (MVL)

The results of an experimental project in American history which introduced to students the methods of historical investigation in specific historical areas through small group research rather than through the college survey course are described in this report. Discussed are (1) the course organization, consisting of two semester units in which…

Describes a laboratory safety program at the University of Delaware. Includes a history of the program's development, along with standard safety training and inspections now being implemented. Outlines a two-day laboratory safety course given to all graduate students and staff in chemical engineering. (TW)

Four computer programs to aid students in understanding inventory systems, constructing mathematical inventory models, and developing optimal decision rules are presented. The program series allows a user to set input levels, simulates the behavior of major variables in inventory systems, and provides performance measures as output. Inventory…

A new interinstitutional instrument for cooperative teacher preparation and curriculum development is needed, preferably to "emerge from a partnership of the old institutions with universities taking leadership under the encouraging sponsorship of state departments of education." A "cooperative clinical teaching center" would focus on both staff…

This seventh in a series of twenty-nine learning modules on instructional execution is designed to give secondary and postsecondary vocational teachers skill in assisting student development of laboratory work plans, in guiding student progress through the use of these plans, and in developing special instructional materials for use in the…
