Described are eight microcomputer systems that are suitable for computer-aided instruction (CAIDI) in chemistry. Specific instructional applications are described to illustrate the wide variety of systems available and their adaptability to problems faced by chemistry teachers. (BT)

Described are 22 computer programs, written in BASIC, currently being used by the Eastern Washington University Chemistry Department. Information on the availability of the programs from the author is provided. (BT)

Described is the use of two models of pocket calculators. The Hewlett-Packard HP67 and the Texas Instruments TI59, to solve problems arising in connection with ionic equilibria in solution. A three-parameter regression program is described and listed as a specific example, the hydrolysis of hexavalent uranium, is provided. (BT)

Discussed is the nature of cyanide poisoning. Included are sources of the cyanide ion, the mechanism of poisoning, the biochemical basis for treatment, and therapeutic measures. (BT)

Presented is a model for solvent effects based on the observation that the excitation energy of all-trans-N-Retinylidenmethyl-n-butylammonium iodide is directly related to the dielectric constant of a series of aromatic and aliphatic solvents as the dielectric constant (e) ranges from 2 to 10.5. (BT)

Described are the results of research in chemical education carried out at the University of California, Berkeley. Individualized instructional materials to teach major concepts of stoichiometry to unprepared students were developed and validated. (BT)

Spectroscopic studies on solutions and x-ray diffraction work on crystals lead to the conclusion that the Metrogen of the pyrimidine ring is preferentially protonated. The correct monoprotonated structures of thiamine and its 4-amino-pyrimidine synthetic precursor are presented. (BT)

Presented are lists of deshielding constants chosen to be easy to remember and to given estimates close enough to measured shifts to allow interpretation of the spectrum of a compound of known structure. (BT)

Presented are the combined test results of chemistry students from seven Central Indiana schools on the ACS-NSTA achievement exam, Form 1975, Part 1. Additional variables investigated include sex, grade level, Longeot classification, and an item analysis of the test items. (BT)

Describes the history of arsenic, the properties of arsenic, production and uses of arsenicals, arsenic in the environment; toxic levels of arsenic, arsenic in the human body, and the Marsh Test. (BT)

Discusses the important challenges facing high school chemistry teachers in the 1980s. Topics include increasing the enrollment of non-science-oriented students in high school chemistry courses and teaching the Interdisciplinary Approaches to Chemistry (IAC) program to college-bound general students. (BT)

Describes a lecture demonstration illustrating Charles's Law with a balloon-balance thermometer. The technique allows a determination of the absolute minimum temperature to within an accuracy of 10 percent of the exact value: -273.15 degrees Celsius. (BT)

Describes an undergraduate organic chemistry course at Colorado State University that employs student-designed laboratory procedures in the laboratory. An outline illustrating the use of this approach is included. Advantages over the traditional approach are detailed. (BT)

Describes a method utilized at Iowa State University for teaching a biochemistry laboratory course for non-majors involving the use of student independent projects and experimental choices. (BT)

Outlines an approach for instruction in a physical chemistry laboratory which combines traditional and project-like experiments. An outline of laboratory experiments and examples of project-like experiments are included. (BT)
