This paper summarizes and extends a study of SES (socioeconomic status) related differences in a mathematics classroom aligned with current U.S. reforms. Qualitative analyses compared the lower- and higher-SES students' experiences with whole-class discussion and contextualized, open-ended mathematics problems. The higher-SES students tended to…

This book explores individual cognitive processes and the psychology of scientific discovery. Nine studies are presented that investigate childrens' and adults' attempts to make scientific discoveries from a theoretical perspective. Contents include: (1) "Investigating Scientific Thinking: Why and How"; (2) "Scientific Discovery as Problem…

The motivational effects of feedback types consisting of the same evaluative components, but differing in the informative components, were studied with 156 German undergraduates in a computer-based learning experiment. A concept-formation task was the learning material. Three feedback conditions were designed: (1) knowledge about result (low…

This paper is an attempt toward the goal of developing an integrated quantitative theory of visual stimulus selection. (Author/RK)

This study considered the structure of adolescents' interactions with artists and art teachers. (Author/RK)

Author investigated the psychological disposition of Soviet teachers and compared them to those of Western teachers. (RK)

The development of concepts of equivalence was studied in a group of 256 children, ages 4-8. The relative difficulty of these concepts is interpreted in terms of the young child's difficulty in understanding spatial arrangement and heterogeneity as irrelevant to numerical size. (Author/KM)

Discussed seven concepts dealing with the further enhancement of cooperative education programs. (Author/RK)

Describes a number of ways in which the adoption of the metric system in the United States will increase the effectiveness of mathematics teaching. It provides a concrete model for many concepts commonly taught in grades K-12, and thus provides a means by which confusion can be alleviated. (JR)

Reflective and impulsive children were instructed to hasten or delay their responses on a test of hypothesis-seeking and constraint seeking conceptual strategies. Latency of response data on pretesting, training, and immediate posttests showed that the attempts to hasten or delay responses were successful in changing response latencies. (ST)

The effects of perceptual pretraining on preferences and concept identification performance in five- and eight-year-old Ss were investigated.

Research studies were conducted to determine the effectiveness of multisensory learning systems in teaching basic concepts to two and five-year-old children. (Author/RK)

Author suggests that new'' or modern'' mathematics never had a valid reason for existing and recommends reform of traditional mathematics curriculum. (RK)

The problem of this investigation was to ascertain the relative effects of two teaching strategies, discovery and expository (telling), on the learning of economic concepts by first grade students, as measured by a criterion test instrument. (Author)
