This study explores seventh- and eighth-grade students' thinking about mathematical patterns. Interviews were conducted in which students solved problems about sequential perimeter and area problems modeled with pattern blocks and tiles, generalized the relationships related to the patterns and represented the relationships symbolically,…

The program and abstracts of the presentations of the 1992 meeting of the Society for College Science Teachers are the topics of this report. Society officers are listed, a history of the society is provided, and membership information is given. The presentations reflect different topics in the teaching of college science. The abstracts of…

This study investigated children's ability to interpret a natural social situation, depicted in a narrative story, and to use their understanding of that situation to generate and apply a mental model of debts and assets in solving problems including negative quantities. Fifty-one American students from a parochial school in a predominantly middle…

The purpose of the study was to identify differences in cognitive skills associated with differing rates of predictive reasoning success for high school biology students, to determine possible correlations between predictive success and cognitive operational level, and to assess whether directed practice facilitated problem-solving success. The…

The realization that the areas of second language and mathematics education share some common features and that educators in these fields may profit by an exposure to research and practice in both fields motivated the production of this paper. From an introduction to the literature, parallels in the history of the two disciplines were recognized:…

The purpose of this study was to determine whether an electronic geoboard, a computer-software program, could be used to assess youngsters' ability to discover facts and relationships in an unlabled and ambiguous situation. Subjects--108 children, ages 6 to 12--were enrolled in grades 1 to 6 in Norwood, New York. The electronic geoboard served as…

These training materials are designed to stress the importance of a close relationship between concepts and skills when teaching mathematics to young children, to present material on the important area of problem-solving, and to encourage adults to use a wide range of appropriate techniques in evaluating their work and children's work in…

The theme of this report is that recent theory and research related to the cognitive domain of children's comprehension of stories have implications for the social domain of children's understanding of interpersonal interaction, since there are important overlaps between the abilities necessary to comprehend stories about social events and those…

A CONCEPT ATTAINMENT TASK IN WHICH CHILDREN ARE ASKED TO IDENTIFY A CONCEPT THROUGH DETERMINING WHICH OF A SET OF OBJECTS ARE OR ARE NOT INSTANCES OF IT WAS USED TO INVESTIGATE THEIR PROBLEM-SOLVING BEHAVIOR. OF PARTICULAR INTEREST WAS THE QUESTION OF TO WHAT EXTENT THEY USED OR LEARNED THE STRATEGY OF VARYING ONE FACTOR WHILE HOLDING ALL OTHERS…

ANACONDA, a computer-based system for analysis of verbal content by data processing is presented as a scientifically more satisfactory substitute for classical content analysis. This system was applied to 40 behavioral science researchers who were interviewed regarding their channels of information for concept formation, problem discussion,…

A set of curriculum papers written mainly by teachers who attended workshops in continuing education is presented. This set is a historical study of the attitudes toward and conceptions of composition that have been held during recent years. The intent of these papers is to provoke significant curriculum change by changing teacher attitudes.…

Describes the reasoning patterns characteristic of the abstract thinking required for higher levels of school science. Discusses control and exclusion of variables, ratio and proportion, conservation involving models, compensation and equilibrium, correlation, probability, combinatorial thinking, coordination of frames of reference, and…

Describes an investigation of the strategies used by 47 high school students in solving volumetric analysis problems in chemistry. Reports that students in the high ability group mainly used the "formula" approach, while those in the low ability group tended to use the "proportional" approach to problem solving. (TW)

Reports on a study in which children aged 7 to 9 years and 11 to 13 years were asked to judge which one out of three wooden blocks would float, given weight and volume information for each block relative to a block that was known to float. Indicates that judgments may have been based on the size-weight illusion. (HOD)

The purpose of this study was to investigate the effects of pair problem solving technique incorporating Polya's problem solving strategy on undergraduate students' performance in conceptual and algorithmic questions in chemistry. The subjects of this study were 89 students enrolled from two first year chemistry classes. The experimental group was…
