Five problems on the generation and study of prime and related numbers are discussed. Solutions to the problems posed will be in next month's presentation. (MP)

Details of pupil exploration as to the largest number of sides that a polygon could have on a geoboard are presented. The problem is not seen as open-ended, but many different avenues of pursuit stem from it. (MP)

Offers teachers and students at all levels some useful approaches to future studies, including a self-test for revealing assumptions that shape futures thinking. Education for life in the future must focus on values and techniques of problem solving since factual knowledge about future conditions can seldom be obtained. (AM)

This study investigated the relationship between several Piagetian abilities and an information processing capacity, and first-grade children's performance on verbal addition and subtraction problems. Results pointed to a sometimes small but consistent relationship between possession of a cognitive ability and solving an arithmetic problem. (MP)

An operational definition of careless errors was provided and used in an investigation of 50 children attending an international primary school in Lae, Papua New Guinea. Results indicated that mathematically competent and confident children tend to make a greater proportion of errors than other children. (MP)

The mathematical problem-solving attitudes of fourth- grade pupils and teachers as related to pupil performance was investigated. Results suggest that most fourth-grade students possess favorable attitudes toward problem solving, and that teachers should continue to foster favorable student reactions toward problem solving. (MP)

Offers an approach to dealing with school discipline problems based on the belief that teachers must set rules and consequences, be specific in giving students messages about behavior, visit parents in home and in school, cooperate with administrators and other teachers, and impose punishments for children that they can understand. (FL)

A method of organizing data known as a stem-leaf plot is presented in detail. This method is viewed to overcome many of the disadvantages associated with the traditional methods of grouping in the frequency distribution table and provides a convenient introduction to data organization. (MP)

Data indicate that relatively advanced science-oriented college students can experience serious difficulties in symbolizing certain meaningful relationships with algebraic equations. Reversal errors in formulating equations were seen to stem from two main sources: (1) a syntactic word order matching process and (2) a semantic static comparison…

Calculators are seen to shift the student focus in problem-solving situations from "how to do it" to "what to do," by keeping computation from standing in the way when pupils write or solve problems. (MP)

Compares the number and types of problem identifications good readers make with the number and types made by poor readers. (HOD)

Two studies were conducted with 8- and 10-year-old children to examine sources of age and skill differences in verbal analogical reasoning. Discussion focuses on the child's "problem space" for the analogy task and possible differences in task understanding that lead to strategy and process differences in older versus younger and skilled versus…

A set of three problem-solving programs designed as drills that give practice in mental arithmetic are reviewed. The programs are viewed to have several weaknesses in style, but are noted as worthy of consideration for purchase. The material is designed to motivate students to practice all four basic operations. (MP)

Describes the stages and outcomes of a junior high school science lesson on erosion and deposition utilizing a "kids as researchers" theme. Stages include awareness, discussion, investigation, experimentation, generalization, and extension. (SK)

The intent is to promote awareness of negative mind sets, which are mental obstructions that prevent problem solvers from perceiving problems in certain ways or formulating solutions. Visual perception, the Einstellung effect, and functional fixedness are presented as types of negative mind sets. Suggestions for remedies are presented. (MP)
