The purpose of this study was to analyze the effectiveness of long-term, tutorial-type computer assisted instruction (CAI) in high school chemistry. Analysis showed scores of non-CAI students significantly higher than the CAI group. However, CAI students learner material faster. (PS)

Discusses a program, consisting of individual conventional experiments and group special projects, along with lectures in analytical courses during the last six to eight weeks of a semester. Concludes that students' different aspects of capability are encouraged after receiving the course. (CC)

Discusses procedures of using the selective absorption properties of manganese dioxide to prepare a short-lived source from the cerium-144/praseodymium-144 system. (CC)

Describes an elective course dealing with chemistry for the consumer. Students investigate consumer products, the chemistry behind these products, and possible ways in which a better understanding of chemistry could help them become more selective consumers. The chemistry of aerosols is a topic given particular attention. (JR)

Discusses professionalism activities taken by the American Chemical Society such as exerting pressures on employers, setting up a manpower policy group, and establishing a legal aid loan program. (CC)

A simple experiment is proposed that can provide the student with some insight into the chemical properties of solids. It also demonstrates the relationship between the Gibbs free energy of formation of an ionic solid and the emf of an electrochemical cell. (DF)
