A study with 57 second graders identified some logically irrelevant transformations that children considered relevant in relation to the weight of an object. Two logically relevant transformations, movement upward and movement downward, were irrelevant to the subjects, whether texture, continuity, temperature, and darkness were generally…

A qualitative approach was used to examine the cognitive processes students engaged in while playing recreational computer games. Participants were 21 high school students. Results indicated that players practiced complex cognitive processes such as interpreting explicit and implicit information, inductive reasoning, metacognitive analysis, and…

Undergraduate biology programs are currently undergoing reform to involve students in biomedical research. Engaging students in more active, hands-on experiments allows students to discover scientific principles for themselves, and to develop techniques of critical thinking and problem solving. This models the world of real scientific research,…

This article reports on the use of a unique number system to facilitate teachers' understanding of the concepts of place value. Teachers' mastery of base-ten may hinder their recognition of the difficulties students have with place value, so the authors created a number system that used five symbols to represent values. Using this system, teachers…

Two studies were conducted to determine the effects of gender, reasoning level, and inductive and deductive computer-simulated experiments (CSE) on problem-solving abilities in introductory general chemistry. In the pilot study, 254 subjects were randomly assigned to control (computer-assisted-instruction tutorials), inductive or deductive CSE…

A study of the effects of the Instrumental Enrichment cognitive intervention program with 41 severely hearing impaired secondary school students was conducted. Experimental and control groups were compared in regard to general cognitive functioning, problem-solving strategies, reading comprehension, and mathematics. Experimental subjects were…

This paper provides a brief overview of some of the current thought on teaching problem-solving and decision-making skills and presents selected exercises that have been used successfully in a graduate course in problem-solving and decision-making strategies. In addition to learning theories that are presented in order to help learners understand…

A thinking-skills course at Montana State University is described, along with recent issues concerning the potential effectiveness of such courses. Advantages and disadvantages of different designs for studying the effects of thinking-skills training are also considered. The focus of the course is: hypothesis formation and evaluation, problem…

Accent on Developing Abstract Processes of Thought (ADAPT) is a program designed to promote critical thinking among college students. Based on the theoretical work of Jean Piaget, it attempts to help University of Nebraska freshmen confront problems and follow them through to logical solutions. In its first year, the program's goals were to…

Linear syllogisms present two premises, each describing a relation between two terms. The individual's task is to infer the relation among the three terms of the linear syllogism, and then answer a question about one or more of these relations. For example, "John is taller than Bob. Sam is shorter than Bob. Who is the tallest?" Students…

It has been suggested that cognitive style interacts with performance on tasks measuring formal thought. It is hypothesized that cognitive style interacts with task context rather than with the underlying formal thought processes. Experiments are reported to clarify the type of task that elicits an interaction and to determine whether such…

Developmental patterns in the solution of verbal analogies, especially the recognition of higher-order analogical relations, were traced. The investigation sought to: (1) provide new developmental tests of a componential theory of analogical reasoning; (2) identify strategy changes during the transition from midchildhood (grade 3) to adulthood…

An aptitude-strategy interaction in linear syllogistic reasoning was tested on 144 undergraduate and graduate students of both sexes. It was hypothesized that the efficiency of each of four alternative strategies--control, visual, algorithmic, and mixed--would depend upon the subjects' pattern of verbal and spatial abilities. Two tests of verbal…

Three studies to determine the effects of adult models on interrogative strategies of children (ages 6-11) are reviewed. Two issues are analyzed: (1) the comparative effectiveness of various types of modeling procedures for changing rule-governed behaviors, and (2) the interaction between observational learning and the developmental level of the…

Four types of proportionality problems were administered to: (1) secondary school students who were enrolled in Project Physics, and (2) students not enrolled in physics. Both samples were randomly selected. Groups were not found to differ significantly in problem solving ability but both revealed that the ability to solve certain problems was…
