Reports results of a study examining the Piagetian stages of Italian secondary school students in which student responses to three puzzles were analyzed. Compares results with studies done in the United States and the United Kingdom. (CS)

Summarizes steps involved in a systematic method for balancing redox equations by inspection. (CS)

Describes a course in chemometrics offered at Tufts University which is designed to provide college chemistry majors with an understanding of potential roles which computers might play in chemical research. (CS)

Describes a topics course offered at the University of New Mexico entitled "Lasers in Chemistry," which is designed for beginning graduate students and advanced undergraduates in all areas of chemistry. (CS)

Summarizes common practices designed to promote safety consciousness in high school chemistry laboratories. (CS)

Provides procedures for demonstrations: (1) the ferrioxalate actinometer, which demonstrates a photochemical reaction; and (2) the silver mirror, which demonstrates the reduction of a metal salt to the metal and/or the reducing power of sugars. (CS)

Describes an approach to titration curves which eliminates the choice of approximations and the algebraic complexity of accurately solving for hydrogen ion concentration. This technique regards moles of titrant as the dependent variable. (CS)

Summarizes results of a three-item questionnaire returned by 43 Michigan institutions expressing views on wearing contact lenses in chemical laboratories. Questions focused on eye protection, type of protection, and use of contact lenses. (SK)

Supplies information to answer typical student questions relating to the significance of "plus" and "minus" superscripts used for electronic states of linear molecules. (SK)

Describes an approach to quantum mechanics exploiting the periodic structure of the elements as a foundation for the quantum theory of matter. Indicates that a quantum chemistry course can be developed using this approach. (SK)

Reviews two classes of controlled release organometals: (1) distributional, to distribute bioactive materials to control a certain target organism; and (2) protective, to protect surface or interior of some structure from attach by organisms. Specific examples are given including a discussion of controlled release for schistosomiasis. (SK)

Describes the rationale for and typical activities of a training program/course (Project TEACH) for teaching assistants. Includes titles of modules used and the nine-week 1979 course schedule. Concludes with selected student comments and suggestions about the course. (SK)

Assesses the impact of teaching assistants' background on the achievement of chemistry students in laboratory sessions they taught. Includes methodology, nature of background data collection, results, and limitations of the study. (SK)

Suggests that a course in cultural science be adopted throughout high schools, where the majority of citizens finished their education. Discusses rationale for such a cultural or multidisciplinary course, teacher training, current practices, and changing from specialized science to a cultural approach. (SK)

Demonstrates how audiotutorial techniques can be applied to the teaching of more advanced subjects (physical chemistry and electrochemistry), and how this can have significant affect on the overall quality of instruction and the mechanics of teaching the course. Includes a general description of audiotutorial instruction. (SK)
