Thinkback is a new instructional process that uses "thinking aloud" strategies developed by Arthur Whimbey and derives its name from the technology of instant video playback. Thinkback is a generalization of techniques described in the program "Problem Solving and Comprehension," which has been used for more than 20 years. The…

This article describes a summer program for high school graduates planning to enter college and major in mathematics, or natural or health sciences. The program is Piagetian-based and designed to assist the students in preparing for problem solving in college by providing multidisciplinary concrete experiences in science and mathematics. (SA)

Data on 140 eighth-grade earth science students were analyzed to see if logical thinking, instructional method, and the interaction between those two variables explained a significant portion of variance in achievement. Logical thinking was found to account for more variation in achievement than did treatment, although treatment also affected…

Described is a three-phase model for teaching problem solving to the middle school student. Phases include cue attendance, thinking aloud, and developing diagrams of steps to solutions. Because middle school students are in a transitional period in their cognitive processes, implementation of problem solving skills seems appropriate. (Author/DS)

Investigated was the relationship between spatial visualization and cognitive development in a sample of 88 Australian freshman teacher education students. Results support the hypothesis that enhanced capacity to visualize is an outcome of overall cognitive development. (HM)

Discussion of course structure in active learning at the college level looks at ways level and type of structure can be varied and manipulated to meet challenges presented by a diverse student body. Issues discussed include the relationship of structure to cognitive style and development, fitting structure to content and objectives, and what can…

Asserts that play is an important medium for young children's learning, one that contributes to the child's cognitive, physical, emotional, and social development. Discusses the qualities that distinguish play from other activities, the skills children develop from exposure to a variety of play experiences at home and in the classroom, and…

The question of how children solve force and motion problems in computer simulations without explicit knowledge of the underlying physics was investigated. Keystroke sequences made by children were saved and analyzed, and children were interviewed to understand their perception of the relationship between keyboard input and on-screen action. (CW)

Presents a study that investigates the knowledge and skills that relate to computer programing. Finds that knowledge and procedural skills are related to computer programing. Recommends that since instruction in computer programing facilitates problem-solving, computer programing courses should be augmented to include teaching template and…

Criticizes the Mitchell and Lawson (1988) report from the viewpoint of individual interview method. Provides Lawson's reply to the comment by showing differences in research philosophy and methods. (YP)

Examined the developmental sequence through which adolescents progress in solving a physics problem (balance beam ratio and proportion) and a social problem (predicting the behavior of a story character). Although most of the 9- through 19-year-olds performed at predictable and similar developmental stages on each task, a minority were more…

Relates research findings on the way primary-grade students communicate mathematical ideas through the use of symbols to a framework for students to investigate the part-whole relationship of quantity. Discusses children's problem-solving abilities, linking word problems and symbols, the importance of context for understanding symbols, and the…

Investigated is whether children would spontaneously model problems with superfluous information and whether their modeling would facilitate problem solving. Included are the addition/subtraction story problems used in this study, introduction, method, results, discussion, and conclusions. (KR)

Presents teaching methods to rectify the tendency of students and even teachers to divide the smaller number into the larger in problem situations requiring division, while recognizing the impossibility of the answer in the situation. (MDH)

Examines the relationships between the development of proportional reasoning strategies and three cognitive variables from Pascual-Leone's and Case's neo-Piagetian theories: (1) degree of field independence; (2) M-space; and (3) short-term storage space. Describes the ability of students to transfer problem-solving schemata to new contexts as well…
