Introduces a problem that can be used to help children develop graph sense. Involves two graphs of which students must determine which one applies to which situation. (KHR)

In accounting for the well-established sex differences on mental rotation tasks that involve cube stimuli of the Shepard and Metzler (Shepard & Metzler, 1971) kind, performance factors are frequently invoked. Three studies are presented that examine performance factors. In Study 1, analyses of the performance of a large number of subjects…

Over the past two decades, calculus reformers have called for the use of alternative pedagogical techniques to promote student learning. Some mathematics instructors have responded by developing a set of student projects intended to hone thinking skills and improve the mathematical writing skills of calculus students. Drawbacks to this strategy…

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)

The third volume of a three volume study of the development and effectiveness of a computer-assisted instruction (CAI) course in undergraduate Physics contains the CAI curriculum. It is broken up into two parts, that is the 1500 CAI course and the problem sets presented via the 1440 computer. For a background and summary of the project see volume…

Investigated here are some of the results which can be obtained using the double-sided straight edge. Seventeen possible constructions are presented with solutions or partial solutions given to most. (MP)

This first in a series on the programable calculator presents a chapter on the basic operations. The series is written for a particular calculator, Hewlett-Packard's HP-25. (MP)

Presents six mathematical problems (with answers) which focus on: (1) chess moves; (2) patterned numbers; (3) quadratics with rational roots; (4) number puzzles; (5) Euclidean geometry; and (6) Carrollian word puzzles. (JN)

Presents four questions (and provides answers) related to biology and chemistry. Items are concerned with genes, sodium transport, osmosis, and early earth history. (RH)
