The unit basis approach to problem solving analyzes a question in such a way that the student clearly sees what data are needed to solve the problem. Two examples are presented to illustrate the approach. (JN)

Explains that, to teach students how to solve problems, defining the problem should be the focus, and the skills to solve the problem should be analyzed. Differentiates between exercises and real problems. (PR)

Describes how Newton's Law of Cooling and the Method of Mixtures are used to solve the basic dilemma of whether to add the cool cream to the hot coffee or to let the black coffee cool down first and then add the cream. (ZWH)

Reviews work found in the psychology literature on the nine-dot problem and suggests implications of research on insight problems. Insight problems refer to a heterogeneous group of problems that require "flashes of insight" or "leaps of logic" on the part of the solver. (ZWH)

Provide guidelines for teachers to help students develop interpersonal skills. Asserts that an enhancement of these skills will in turn help students develop problem-solving skills. (ZWH)

The use and misuse of the superposition principle to analyze electrical circuits are discussed. (KR)

Perturbation theory is presented as an invaluable tool for solving a majority of physically interesting problems involving both macroscopic and microscopic objects. Its use in Newtonian mechanics is emphasized.. The method is illustrated with three examples. (KR)

This paper is a progress report of the first phase of a project which essentially seeks to replicate previous studies using the successful/unsuccessful design in an attempt to: (1) corroborate the surface/deep structure conclusion which has become an essential component of an understanding of problem-solving; (2) examine more closely the nature of…

Both teachers and students alike acknowledge that genetics and genetics problem-solving are extremely difficult to learn and to teach. Therefore, a number of recommendations for teaching college genetics are offered. Although few of these ideas have as yet been tested in controlled experiments, they are supported by research and experience and may…

Presents the opinion that the learning environment of recitation classes can be vastly improved if instructors pay attention to some basic learning principles. Summarizes these learning principles and presents a specific example of their application. (GS)

Discusses some theorems and properties of figures produced when circles are tangent to one another. (GA)

Provides a simple routine which allows first-year physics students to use programmable calculators to solve otherwise complex electrostatic problems. These problems involve finding electrostatic potential and electric field on the axis of a uniformly charged ring. Modest programing skills are required of students. (DH)

Describes a computer program used in an experiment in which the partial molal volumes of sodium chloride solutions are calculated as a function of concentration from densities measured with a pycnometer. The complete program listing (also available from the author on disk) and a sample run are included. (JN)

Presents a technique which aids students in solving static problems involving three or more torques about a given axis. The method is longer and equivalent to the standard method, but students experience success with this new way to treat the more complicated equilibrium problems. (DH)

Outlines a problem-solving method for beginning chemistry students that utilizes specific, concrete steps as well as computer-assisted tutorials. The method involves an approach referred to as the Factor-Unit Method coupled with a graphical "road map" which allows students to trace problems from start to finish. (JN)
