How slides may be used to combat student remoteness and the excessive standardization of presentation which many teachers find objectionable in language laboratory work. (FWB)

Discussed are the contributions of the Regional Educational Laboratory for the Carolinas and Virginia (RELCV) to fourteen junior colleges. Most attention is given to the implementation of the idea of "performance agreements, a contract between the college and a faculty member tying his salary increases to the performance of his students. (LS)

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)

Research supported in part by grant MH-07346 from the National Institute of Mental Health, and a grant from the Illinois State Department of Mental Health.

Offers suggestions for teaching some aspects of water economy in plants. These include diffusion/osmosis, water transport, the part played by turgor in structural support, and its implications for plant organs or whole plants. Several practical demonstrations/experiments are also described. (JN)

In a poster session, students explain an experiment with the help of a poster that outlines the experimental procedures followed. Suggestions for preparing posters and conducting poster sessions are provided. A sample poster on the strength of electromagnets is also provided. (JN)

Describes a course used to teach freshwater ecology to graduate and undergraduate students at the University of Michigan Biological Station. Explains how students receive an introduction to lake ecology and work on applied resource management questions concerning local lakes and streams. Gives case study examples. (SB)

Describes a three-part experiment designed to introduce cyclic voltammetry to graduate/undergraduate students. Part 1 demonstrates formal reduction potential, redox electron transfer, diffusion coefficient, and electrochemical reversibility. Part 2 investigates electrochemical behavior of acetaminophen. Part 3 examines such experimental variables…

A PASCAL graphics and instrument interface program for a Z80/S-100 based microcomputer was developed. The computer interfaces to a stopped-flow spectrophotometer replacing a storage oscilloscope and polaroid camera. Applications of this system are discussed, indicating that graphics and analog-to-digital boards have transformed the computer into…
