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 a minicourse on experimental hypotheses. The courses which treats the investigative nature of biology as a major theme, teaches nonrigorous problem-solving and engenders the excitement of self-discovery. Manipulation of variables in relation to controls, the principles of deduction and induction, and their application to selected…

In early January 2003, "Education Week" released a new report on the status of teaching in the United States and concluded that many states are taking steps to recruit and retain skilled teachers, but few efforts focus on the schools where these teachers are needed most. Drawing upon a large national database, "Quality Counts…

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…

Classroom techniques are suggested for teaching English-as-a-Second-Language (ESL) students cognitive and academic skills needed for academic success, using the reading and analysis of folk tales. Skills targeted include comparing and contrasting, evaluating ideas, supporting claims with facts and evidence, organizing and grouping ideas, and using…

The relative effects of cooperative, competitive, and individualistic goal structures were compared on achievement and the acquisition of high-level cognitive reasoning strategies. Results indicate that cooperative interaction, promoted higher achievement and the discovery of superior cognitive reasoning strategies. (Author/GK)

This study demonstrated an aptitude-strategy interaction in linear syllogistic reasoning; specifically, that the efficiency of each of four alternative strategies for solving linear syllogisms would depend on subjects' verbal and spatial abilities. The four strategies, as well as research methods in aptitude-treatment interaction, are discussed.…

Describes a mathematical investigation centered on collecting and analyzing data in a scientific setting. The first experiment teaches the basics of data collection--students should be able to identify variables that might have affected experimental results. The second activity includes designing an experiment to control for these variables. The…

Describes a teaching activity that improves students' scientific reasoning by focusing attention on the causal, explanatory nature of psychological theories. Students learn and use an argument form called Inference to the Best Explanation (IBE). Includes examples of this technique and student responses to the course. (MJP)

Described are inconsistencies, definitions, and examples and their complex relationship which can be used to interpret students' reactions to the geometric tasks used to investigate inconsistencies in student thinking. Discusses the nature of definitions, the value of precise vocabulary, the use and limitations of prototypes, and the power of…

Investigates gender differences and the role of spatial visualization in problem solving in high school geometry. Reports that, whereas males and females differed in spatial visualization and in their performance, they did not differ in logical reasoning ability or in their use of geometric problem-solving strategies. (Author)

Describes the contents of a book entitled The Care and Feeding of Ideas: A Guide to Encouraging Creativity which considers the thinking process, why skills need to be developed, and how students use or should use these thinking skills. (RT)

Using Piagetian tasks designed to assess specific mental structures, researchers investigate the relationship between logical thinking structures and the ability of students to construct and interpret line graphs. Results revealed that a significant correlation exists between the aforementioned variables. Suggests and cautions that only at certain…

This article discusses empowering thinking skills such as brainstorming, problem solving, analysis; comparison/contrast and how to cultivate these abilities in gifted children. Examples are given of ways for teachers to model thinking skills for students. The response of a student to the ideas of the article is included. (PB)

Middle school teachers (n=123) in 2 southeastern states completed surveys examining the relationship of their abstract-concrete thinking levels to their multiethnic beliefs. Teachers' beliefs about multiethnic issues varied according to their individual thinking styles, with concrete thinkers holding beliefs that were less likely to nurture…
