Homework was optional during the first half of an engineering course but mandatory during the second half; test scores were higher during the second half. Discusses whether this can be attributed to the mandatory homework. (MLH)

Two important factors that influence problem solving are the nature of the task and the kind of knowledge brought to the problem by the solver. After a consideration of the definition of a problem, puzzle problems are discussed, as are problem representation and general processes of solution. Also discussed is the question of solving problems that…

The goal of this pamphlet is to provide instructors of various scientific disciplines with mathematically accurate graphs of elementary polynomial functions. The figures in this pamphlet are intended to provide suitable material for the preparation of classroom handouts and overhead transparencies. In addition, sample sets of exercises are…

This sourcebook contains mathematical exercises, problems, and projects concerning pollution which are accessible for students in grades 6-9. The exercises, which are designed to improve computational skills, are classified according to topics usually taught in the mathematical curriculum of the middle school. (CT)

A game modelled on football can be used to provide students with practice in solving algebraic equations. (SD)

Described is a calculator race that is designed to require a fast touch with the calculator and also the ability to apply mathematical knowledge. Sample questions are given. (MP)

A new set of problem cards intended to bridge the gap between Nuffield assignments in primary mathematics and secondary mathematics courses is described. (DT)

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)

Five graded sets of examples of alphametrics are provided. The puzzles are suggested for use in developing the traits of considering all possibilities and systematic working. (MP)

This problem deck contains over 150 problems related to the module "Using Tables to Solve Problems." The problems are presented at five levels of difficulty and contain four basic types of two-dimensional tables: (1) constant sum; (2) constant differences; (3) constant quotient or ratio; and (4) constant product. (MP)

Problems short on computation and long on logical thinking are suggested for development of logical thinking. A set of such problems is presented. (MP)
