Thirteen computer/calculator programs (available from authors) are described. These include: representation of molecules as 3-D models; animated 3-D graphical display of line drawings of molecules; principles of Fourier-transform nuclear magnetic resonance; tutorial program for pH calculation; balancing chemical reactions using a hand-held…

Investigated superiority of instructional strategies (factor-label method, proportionality, use of analogies, use of diagrams) in teaching problem-solving related to mole concept, gas laws, stoichiometry, and molarity. Also investigated effectiveness of strategies for students (N=609) with different verbal-visual preferences, proportional…

Results of modifying mastery learning strategy to two diagnostic cycles with high school chemistry students (N=156) indicated that achievement of mastery learning students was significantly greater than that on nonmastery learning students. Attitudes toward science/science instruction were not significantly different but were positive in both…

Results of a National Science Foundation survey indicate that developing shortages of science and engineering graduates in the current labor force for the most part do not apply to chemists and chemical engineers. (Author/JN)

Substantially self-paced programed learning at Sheffield City Polytechnic Metallurgy Department was found to be better than conventional lectures, provided that new topic areas covered were relatively small, as demonstrated by using inexpensive, simple instructional materials. (Author/JN)

Data are presented in chart and graph form focusing on research and development (R&D) funding by the federal government, including federal obligations for total R&D (largest increases for defense and space); research; scientific disciplines; development; basic research; applied research; university research and applied research; and funds…

Outlines a survey of laboratory practices and policies for employee protection from exposure to chemicals. Findings support the argument that academic, industrial, and other research laboratories are different from the manufacturing environment and should have a different toxic chemical policy and standards. (Author/SK)

Presents some general characteristics of "older" students and describes courses and instructional strategies in the physical sciences related to these characteristics. (SK)

Describes a course designed to improve writing ability and ability to use chemical literature, emphasizing course materials, teaching techniques, and effectiveness based on two years of experience. (SK)

Details the use of measuring instruments, computer terminals, and other high technology laboratory aids for the visually handicapped chemistry student. Use of these aids at East Carolina University is also described. (CS)

Poor behavior in one of 12 mixed-ability chemistry classes led to a stigma attached to it by school staff. Analysis of examination marks indicates the reputation was not justified in terms of academic achievement, demonstrating the ease with which academic achievements can be hampered unwittingly by teacher prejudices. (Author/JN)

Provides instructions and a list of materials needed to demonstrate: (1) a model of the quantum mechanical atom; (2) principles involved in metal corrosion and in the prevention of this destructive process by electrochemical means; and (3) a Thermit reaction, modified to make it more dramatic and interesting for students. (SK)

Evaluates the effectiveness of student interaction in computer assisted instruction (CAI) in enhancing achievement in chemistry laboratories. One group of students interacted with the computer in simulated laboratory activities; a second group did not interact. Advantages of interactive CAI were found for tasks requiring interpretation and…

Twelve court cases involving laboratory situations are reviewed in chronological order. Report includes five statements indicating when an instructor is not liable as well as guidelines to improve laboratory safety and provide some measure of liability protection for the instructor. (JN)

Two demonstrations are described: (1) a sunset effect using a gooseneck lamp and 20 sheets of paper and (2) the preparation and determination of structural features of dimethyl sulfoxide (DMSO) by infrared spectroscopy. (SK)
