To overcome learner dependence when modeling cognitive processes, one teacher used direct teaching of specific thinking skills with her middle school language arts students. The teacher introduced the skill of analyzing for personification to her students. The class experimented with the skill, completed the task, and applied the skill to…

Investigated the extent to which 28 academically able students used energy conservation ideas in solving written and practical problems. Interviews show problems they had in understanding and using the concepts of work and energy and that the idea of energy conservation was rarely used spontaneously in relevant situations. (JN)

Research identifies two interrelated memories--one that retains facts and symbols and one that retains motor and problem-solving skills. These and other findings challenge educators to determine what students should memorize, to help them move from random memorization to creating useful concepts, and to teach students to use memory in problem…

This is a qualitative study of 22 9th graders performing generalizations on a task involving linear patterns. Our research questions were: What enables/hinders students' abilities to generalize a linear pattern? What strategies do successful students use to develop an explicit generalization? How do students make use of visual and numerical cues…

This paper describes how one group of students developed personally meaningful ways to reason mathematically within the context of measurement. Episodes taken from a first grade classroom in which a 4-month teaching experiment was conducted are presented. One of the goals of the teaching experiment was to develop instructional sequences designed…

The purpose of this study was to investigate the effects of the Casio 9850 and the TI-85 graphing calculators on college students' procedural skills and conceptual understanding in two different developmental mathematics courses. The courses used in this study were Elementary Algebra and Intermediate Algebra. Both the non-graphing calculator group…

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…

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)

Focuses on learning through fictional encounters for conceptual development and emphasizes professional educating rather than training in discussing nursing education. (RK)

To test the proposition that different types of pretraining would result in different strategies" in the solution of concept identification problems, a design was used in which length of postfeedback intervals was made dependent on the correctness of Ss response. (Authors/MB)

Attempts to determine the age at which the concept of middleness," or intermediately positioned object, emerges and is functional. (MB)
