Laboratory activities give students an opportunity to interact with computers in modes ranging from remote terminal use in laboratory experimentation to the direct hands-on use of a small digital computer with disk memory and on-line plotter, and finally to the use of a large computer under closed-shop operation. (Author/TS)

Four prepared computer programs are used as teaching and design aids in a senior-year course. They incorporate more than half of the mathematical models and analysis developed throughout the course. (Author/TS)

Methods, based on historical techniques, are described which may be used to determine the relative density of irregularly shaped objects of various composition. (TS)

The role of phosphates in environmental issues and in detergents is discussed. Experimental procedures are described for colorimetric determination of orthophosphates. (TS)

Describes and compares procedures and results of determination of colorimetric, potentiometric, and amperometric endpoints of an oxidative titration of arsenite by iodine. (TS)

Describes a dry- lab" experiment for the college freshman laboratory, in which the essential features of Browian motion are given principles, using the Monte Carlo technique. Calculations principles, using the Monte Carlo technique. Calculations are carried out by a computation sheme based on computer language. Bibliography. (LC)

Assesses the educational state-of-the-art regarding physiological simulation. States the importance of conventional physiology laboratory exercises involving living material. (MA)

Describes an advanced laboratory experiment that introduces two important reactions in organophosphorous chemistry, the Arbuzov and the Atherton-Todd reactions. (CS)

Provides information concerning self-acceleration and self-inhibition phenomena and a description of an experiment in alkane pyrolysis that exemplifies these phenomena. (CS)

Describes an experiment used to study dielectric properties of materials. Values of the dielectric loss tangent can be determined at low frequencies from Lissajous figures formed on an oscilloscope. Some mineral rock specimens show Debye-type relaxation peaks at frequencies in the region of 1 to 500 Hz. (Author/DS)

Presents computer assisted instruction (CAI) applications involving prelab simulations of organic chemistry experiments in advance of performing the actual experiments. Tables present the PLATO lessons used in the laboratory; and a comparison of average times for students to complete laboratories with and without the PLATO system. (CS)

Described are graphic computer simulations of laboratory experiments in modern physics developed for student use prior to each laboratory and which replace pre-lab briefing. Experimental simulation is intended to familiarize the students with the experiment, and to allow the students to try a larger number of "experimental" combinations of…
