Contains a set of questions (plus possible, but certainly not uniquely satisfactory, answers) requiring no more than a concurrent first-year, college level course, a data handbook, and a willingness to apply fundamental chemical ideas to the systems which surround us. (Author/TS)

Presents the second in a series of articles in which problems related to introductory physics courses are presented. The twenty problems deal with nearly all aspects of physics and are presented in a practical and thought-provoking manner. (RR)

Describes an alternative method to algebraic procedures for solving problems involving the proportional composition of a mixture. (TS)

Describes the process of self-regulation, which Piaget hypothesizes governs all intellectual growth, and suggests a way in which homework problems in a chemistry course can be used to provide students with an opportunity for self-regulation. (MLH)

Describes the problem-solving behaviors of experts and novices engaged in solving seven chemical equilibrium problems. Lists 27 behavioral tendencies of successful and unsuccessful problem solvers. Discusses several implications for a problem solving theory, think-aloud techniques, adequacy of the chemistry domain, and chemistry instruction.…

Discusses the difference between a generic chemistry problem (one which can be solved using an algorithm) and a harder chemistry problem (one for which there is no algorithm). Encourages teachers to help students recognize these categories of problems so they will be better able to find solutions. (TW)

Presented are three physics problems from the New Zealand Entrance Scholarship examinations which are generally attempted by more able students. Problem situations, illustrations, and solutions are detailed. (CW)

Presents 15 energy-related physics problems, including a brief indication of the essential features for solving each problem. Problems reflect various energy-related situations and involve different areas of physics. (SK)

Contains two articles relating to chemistry examination questions. One provides examples of how to sequence multiple choice questions so that partial credit may be given for some responses. The second includes a question and solution dealing with stereoisomerism as a result of free radical chlorination of a nonstereoisometic substance. (TW)

Differentiates between problems, exercises and algorithms. Discusses the role of algorithms in solving problems and exercises in chemistry. Suggests that very real differences exist between solving problems and exercises, and that problem solving steps can be and should be taught in chemistry education. (TW)

Students' conceptions of the concept of force are discussed. Possible problem formats and exercises are presented. The need for many formats and variations to help students' resolve their conflicting ideas about physics concepts is stressed. (CW)
