Seventy-two educable mentally retarded 11-year-old children were divided into a low mental age (MA) group (MA 87 months) and a high MA group (MA 106 months) to compare performance on the solving of variously presented verbal arithmetic problems. (Author/MC)

The effect of cognitive style on the performance of four groups of college students (n=326) who used different strategies of study to comprehend prose was investigated. The cognitive styles of the subjects (field dependence/independence) interacted with the strategies of study and seem to affect performance on comprehension of prose at posttest.…

Studies were conducted to determine how historical knowledge is organized, stored, and retrieved during problem solving. Subjects for the experiments consisted of professional historians, graduate students, college students, 12th graders, 9th graders, and 6th graders. (RM)

Evaluated the possibility that three-year-olds solve small-number conservation problems by an empirical procedure whereby the sets are quantified each time presented. Children chose the more numerous of two arrays, one containing two elements and the other three elements. Results disconfirmed claims that three-year-olds can conserve small numbers.…

The problem-solving performance of elderly individuals was facilitated by manipulating the demands of problem-solving tasks. The fact that elderly individuals can use more efficient strategies under certain circumstances suggests that the elderly have such strategies in their repertoires. (Author)

Elementary combinatorial problems may be classified into three different combinatorial models: (1) selection; (2) partition; and (3) distribution. The main goal of this research was to determine the effect of the implicit combinatorial model on pupils' combinatorial reasoning before and after instruction. Gives an analysis of variance of the…

Discusses the role of instructional design in the development of learning theory. Topics discussed include the acquisition of knowledge and skills; models of teaching; the teaching and acquisition of concepts; influences on retention; and the integration of procedures, principles, and concepts for solving problems.

A mathematician who has been teaching for 58 years discusses 3 types of knowledge that are subjects for teaching or learning (what, how, and why) and why teaching must include problem solving or the use of the Socratic, Moore, or discovery method. (MKR)

Reports on a small-scale study of 13 dyads working at number tasks that found "sidework," a modified form of associative interaction, gave rise to more high order talk and to more posttest learning than did collaboration. Suggests sidework may have greater potential to enhance students' learning than the collaborative mode. (TJQ)

Proposes that teaching methods be changed to move away from a positivist model toward an ecological model. Discusses three assumptions for future practice involving holism in environmental studies; the role of values in environmental studies; and the process of learning. (Contains 26 references.) (MDH)

Students' needs and research on learning should inform teaching practices. Makes suggestions for improving instruction such as using students as ombudspersons to provide feedback on class concerns, focusing on process skills, and incorporating problem-based learning into the curriculum. Also includes examples of successful programs and summaries…

Discussion of recent changes in technology education focuses on the learning process of technological problem solving. A conceptual framework is proposed that includes knowledge, skills, and cognitive models. An evaluation-modification model flow chart is also explained. (Contains 52 references.) (LRW)

Investigates the effect of collaboration on problem-solving performance and learning in the context of a complex, video-based mathematics problem. High-achieving 6th-grade students (N=96) were assigned to collaborative or individual problem-solving conditions. Results reveal that students in the collaborative condition outperformed students in the…

This qualitative case study focused on the nature of science learning through open-ended problem solving with eighth graders. Discusses results of interviews and observation that suggested students only partially derived accurate mental models, and makes recommendations for improving student understanding in open-ended environments. (Contains 95…
