Seventy fifth-grade students in Australia were observed as each solved a jigsaw puzzle. Boys obtained higher scores on a measure of cognitive style and took less time to complete the jigsaw task; the two measures were significantly correlated. Uses of tangrams are also discussed. (MNS)

Highlights major areas of research in mathematics education and examines four areas in need of additional attention: (1) the role of technology in mathematics teaching; (2) models for evaluating mathematics teaching; (3) development of estimation skills; and (4) the role of affective variables in the teaching of problem solving.

Results of interviews with high school chemistry students (N=14) during equation-solving sessions indicate that those who were able to construct diagrams consistent with notation of their balanced equation possessed good concepts of subscript and the balancing rule. Implications for chemistry teaching are discussed. (DH)

Describes investigation of effectiveness of computer-presented organizational/memory aids (matrix and verbal charts controlled by computer or learner) as instructional technique for solving Pico-Fomi problems, and the acquisition of deductive inference rules when such aids are present. Results indicate chart use control should be adapted to…

Investigated effects of teaching an explicit approach to problem solving on the mathematical chemistry achievement of preparatory college students (with a control group being taught dimensional analysis as its problem-solving strategy). No difference in cumulative achievement between the groups was found. Interpretations of the results obtained…

Describes a study which analyzed problem solvers' error detection processes by instructing subjects to think aloud when solving statistical problems. Effects of evaluative episodes on error detection, detection of different error types, error detection processes per se, and relationship of error detection behavior to problem-solving proficiency…

The purpose of this study was to develop a procedure for the evaluation of M-demand of chemistry problems. It was shown that dimensional analysis upon the Neo-Piagetian theory of Pascual-Leone could help science teachers to understand the epistemological basis of their discipline. (CW)

Described is an instructional aid that employs artificial intelligence methods to assist students in beginning economics courses to improve their problem-solving skills. Discussed are the rationale, structure, and evaluation of this program. (CW)

Two hypotheses derived from the theory of action identification, which predicts that people are more likely to adopt a novel course of action if they concentrate on the "how" rather than the "why" aspects of their behavior, were tested with 95 undergraduate students. Hypotheses examined how the level of action identification…

Describes a study to determine middle school children's representational strategies to form part-whole or part-part relationships for relational numbers such as proportions, ratios, or fractions. Quantitative and qualitative analysis revealed that children prefer a part-part representation to solve relational quantity problems. (15 references)…

Provides new evidence for mathematical problem-solving abilities of preschool children. These problem-solving behaviors occurred in a study of sharing of discrete items by dealing, in which we examined the abilities of three categories of counters to solve a discrete redistribution problem. Identifies problem-solving strategies used in the context…

Presents study results suggesting some malleability in learning strategies that flow from cognitive style. Examines the effects and practicability of restructuring training as a means of addressing individual learner differences. Reports that training enhanced performance on two dependent measures tasks. Concludes that field-dependent learners…

A two-stage problem-solving strategy involving cue cards and their gradual withdrawal was used to teach nine sheltered workshop employees how to prevent work-related accidents. Results indicated that participants used the strategy appropriately and generalized their skills to similar and dissimilar situations up to eight weeks after training.…

Investigates the effect that manipulation of the extent of formal reasoning required for solving chemistry problems has upon student performance, and presents a cognitive model for the qualitative analysis of that effect. Concludes that the developmental level of students is the most important predictor of problem-solving success given significant…

A model for problem solving stressing both psychological and cultural influences is presented. This model is based on the analyses of how graduate students (n=10) solve organic synthesis problems, along with two models of problem solving and a constructivist epistemological stance. (KR)
