Safety issues specifically related to the analytical laboratory are discussed including hazardous reagents, transferring samples, cleaning apparatus, eye protection, and equipment damage. Special attention is given to techniques which not only endanger the technician but also endanger expensive equipment. (CW)

Presented is the course outline and proposed science content for this course. The structure, sessions, and evaluation of the course are discussed. (CW)

Investigated are the context dependency and construct validity of practical skill assessment in science which may include the skills of observing, manipulating, planning, interpreting, reporting, and self-reliance. Pupil performance on a variety of practical tasks were compared with external examination grades in biology and chemistry. (CW)

Described is a curriculum survey of general chemistry courses at the college level and an evaluation survey of the advanced placement chemistry examination. Results indicated that the AP chemistry course should remain broad in coverage and should expand its laboratory component. Analyses also indicated that the AP exam was appropriate and valid.…

Described is a 35mm projector demonstration which combines the advantages a highly magnified view of the sample zone as it undergoes dispersion and the ability to show more than a single-line flow injection analysis manifold. Manufacture and use of the slide for demonstration are discussed. (CW)

This literature review focuses on recent studies devoted to hypothesized aspects of social relatedness in autism, discussing attachment and social interest, recognition of and communication of emotions, social cognition, social communication, symbolic play, neuroanatomy of social relatedness, and neurochemistry of social relatedness. (JDD)

Outlined is the development and use of oxidants for use in elementary organic chemistry classes. Discussed is the oxidation of alcohols to carbonyl compounds, and the oxidation of primary alcohols or aldehydes to carboxylic acids. (CW)

Discussed is the background, performance, and future plans of the four medalists from the United States in the 1990 International Chemistry Olympiad. (CW)

Described is how spreadsheet and problem solver microcomputer programs may assist students in performing mathematical calculations. Discussed is the application of the equation solver "MathCAD" to various areas in the undergraduate curriculum. (KR)

Described is the five-week Governor's School course emphasizing chemical reactions for high school seniors. Students took two courses: a subject concentration in humanities or science and a global issues course. The course format included both lecture and laboratory activities. (KR)

Presented are five examples of the application of computer technology to undergraduate chemistry instruction. Topics include: an interface for kinetic experimentation; theoretical calculations; automation of chemical techniques; searching the chemical literature; and Huckel molecular orbitals. (CW)

Discussed are the construction and uses of a version of a photoelectric colorimeter by students. Included are materials needed and four experiments which use the equipment. Sample results are shown. (CW)

Described is a method that can be used to obtain molecular or atomic term symbols. Several examples accompany an explanation of the method. (CW)

This paper reports on the success of a laboratory teaching technique for teaching undergraduate chemistry. Discussed are the premises of the approach, and the use of the computer, the explorations, and the seminar which are included in the course. (CW)

Described is a spectrometer that can be used simultaneously by seven students to observe a single spectrum emitted by an element or compound in a single light tube against a calibrated screen. Included is a list of materials, directions for assembly, and procedures for use. (CW)
