As in the project after which it was modeled, a Wisconsin program finds that volunteers can be fine teachers of exceptional children. (Editor)

Details are provided of computer-simulated experiments developed by the co-directors of the Learning Research and Development Center (LRDC), University of Pittsburgh. The initial materials were designed to help students learn physics. New materials are being developed along similar lines for elementary mathematics. The views of the creators are…

An approach to how to expand explorations of determinants is detailed that allows evaluation of the fourth order. The method is built from a close examination of the product terms found in the expansions of second- and third-order determinants. Students are provided with an experience in basic mathematical investigation. (MP)

A Norman window consists of a semi-circular section mounted surmounting a rectangular section. Modifications to a simple problem are presented that assume parts of the window are made with stained glass. The goal is to maximize the level of light transmission with a fixed perimeter. (MP)

College students (N=136) completed a questionnaire indicating the relative likelihood that they would turn to seven potential help-givers with personal or career problems. For personal problems, students indicated they would turn to a close friend for help. For career problems, students would seek help from a professional. (Author)

When problems defy solution, mathematicians can settle for "almost." This branch of mathematics (called computational complexity) encompasses both the number of parts involved in a problem and the intricacy of their interrelatedness. Current research in this area is discussed, considering various computer applications involved. (JN)

Describes an activity which introduces students to each other while introducing the concept of Cartesian coordinates. Also describes an activity for finding the least common multiple, and computer programs (with listings) for generating shapes resembling windowpanes and for determining amounts wagered in a golf game. (JN)

Several brief articles are included in this section. "Purple Puzzlers" are challenging problems for algebra students. "Linear Invaders" is a game to reinforce concepts of graphing lines. "The Diagonal Method" is used to prove that the real and natural numbers cannot be put into one-to-one correspondence. (MNS)

There is a large gap between the computer's potential to solve problems in a hurry and the American manager's knowledge of how to use it to do that. The concept is best captured by two frequently heard words: computer literacy. (SSH)

Found no single sequence of interaction phases that led to successful or unsuccessful group problem solving. Successful groups, however, tended to begin their discussions by attempting to analyze the problem before searching for solutions; unsuccessful groups immediately began searching for solutions. (PD)

Provides ideas and suggestions for helping students increase their problem-solving skills, including a four-step general problem-solving approach. Specific examples (considering qualitative problems and problem sequence) and comments on testing/grading are also provided. (JN)

Index cards, masking tape, pizza shells, golf tees, and empty soda bottles can be used to make manipulative objects to be used in children's mathematics games. Twenty-two games that provide practice in number drills and problem solving are described, along with instructions for making objects needed for the games. (PP)

Provides historical perspectives on preservation of records and highlights needs in library preservation, including a systems or engineering approach to conservation problem solving. Current educational efforts of Library of Congress and United States library schools such as School of Library Service at Columbia University are outlined. Two…

Describes a course designed to familiarize students with alternative sources of energy, with emphasis on problem-solving strategies. Includes list of major topics/subtopics addressed and list of textbooks and recommended readings on alternative energy sources. (JN)
