Examines changes in the broad cultural background which provide the context for thinking, and how such life-style changes may have influenced the decline of reasoning skills and styles fundamental to the sciences. Considers peasant/rural farming, new world, and postaffluent society life-styles and science education in the latter. (Author/SK)

A cognitive-based system of analysis of spoken discourse was designed to provide details about the way pupils think and talk about issues arising from prose material. Written and spoken responses were analyzed to examine the effects of intellectual ability, differences in the stimulus passage, and prior small group discussion. (Note: Page…

This study reports the characteristics of the 4,751 high school students (out of 374,527) who achieved perfect scores in 1 or more subtests of the 1991 PLAN academic performance test, an academic assessment of 10th graders. Comparisons by gender, ethnicity, and subtest (English, Mathematics, Reading, and Science Reasoning) and a profile of…

Describes the importance of learning to connect separate universes of knowledge into a coherent whole. It is a mistake to emphasize connecting schools to the Internet without considering the kinds of thinking processes students need in order to learn from the information they access. (LMI)

Discussed are possible reasons behind the inconsistencies in the learning of calculus. Implicated are students' beliefs, mathematical paradigms including concept image and concept definition, language use, and curriculum sequencing. (KR)

Discussed are the issues of inconsistencies and compartmentalization and the use of inconsistencies in the classroom. Included are discussions on paradoxes, the naive student, logical reasoning ability, and the development of the students' cognitive structures. (KR)

Discusses a system of classification for students' inconsistent ideas in mathematics, the sources of students' mathematical inconsistency, and instructional strategies for helping students to resolve apparent learning inconsistencies. Language, curriculum, and instruction are included in the discussion. (KR)

Compared the use of conditional logic in adult-adult and adult-child conversation. Results indicated that conversation patterns and inferences were similar except that children made fewer independent inferences and shifts in taxonomic level and responded more frequently to socially controlling statements than did adults. (AA)

Describes the Plane Geometry System computer software developed at the Educational Computer Systems laboratory in Sofia, Bulgaria. The system enables students to use the concept of "algorithm" to correspond to the process of "deductive proof" in the development of plane geometry. Provides an example of the software's capability…

Explores the role that symbolic-graphical calculators can play in the current calls for reform in the mathematics curriculum. Discusses symbolic calculators and graphing calculators in relation to problem solving, computational skills, and mathematics instruction. (MDH)

This article compares measures of abstract thinking preference and divergent thinking to standard mathematics ability measures such as the Scholastic Aptitude Test (SAT). In this study involving gifted tenth graders, mathematical creativity was found to be a special kind of creativity not necessarily related to divergent thinking ability. (PB)

There have been few discoveries in geology more important than "deep time"--the understanding that the universe has existed for countless millennia, such that man's existence is confined to the last milliseconds of the metaphorical geological clock. The influence of deep time is felt in a variety of sciences including geology, cosmology,…

This teaching guide provides an integrated framework for teaching thinking skills which involves both teaching thinking in a separate program or course and infusing the teaching of thinking into standard subject area instruction across the curriculum. Individual chapters deal with the following topics: (1) the nature of thinking skills and…

This book was written to help teachers gain a better understanding of children who are failing in school and to provide a systematic process of attacking their learning problems. The text presents workable principles for determining probable causes of learning problems and for selecting suitable, effective remedial activities. Learning problems…

This study investigated the grouping effect on student achievement in a chemistry laboratory when homogeneous and heterogeneous formal reasoning ability, high and low levels of formal reasoning ability, group sizes of two and four, and homogeneous and heterogeneous gender were used for grouping factors. The sample consisted of all eight intact…
