Investigated changes that occurred in sixth- and seventh-grade teacher and student discourse when teachers endeavored to implement extended teacher wait-time in a sequence of seven lessons related to probabilistic reasoning. Results indicated that teacher wait-time increased from an average of 1.9 to 4.4 seconds during the lesson sequence. (JN)

Describes a course in which a modified version of the Whimbey technique was used to teach verbal reasoning and vocabulary skills to minority high school students. (DF)

Found that increases in cognitive complexity and construct system abstractness significantly related to the use of (1) a greater number of persuasive strategies; (2) more listener-adaptive persuasive strategies; and (3) formation of more complex and abstract impressions of interaction partners. (PD)

Presents ideas to promote higher-level thinking in general chemistry classrooms/laboratories, focusing on applications of Patricia E. Blosser's taxonomy to enhance students' convergent/divergent/evaluative thinking. Compares Blosser's taxonomy with Bloom and Piagetian taxonomies, suggesting a combined Blosser/Piagetian taxonomy to achieve goals of…

Experimental results indicated that verbal intelligence was the best predictor of childrens' overall performance on a paired-associate learning task. Teachers' ratings provided a surprising degree of predictive efficiency for abstract recall which was redundant with verbal intelligence. (Author/JAC)

Investigates spontaneous reasoning of 709 French, Belgian, and British students in elementary dynamics using the relations between force, energy and motion as the study topic. Students were selected from the last year at secondary school to the third year at university. (HM)

Current studies of cognition emphasize the contrast between two approaches to analysis of individual differences. It is concluded that the cognitive components approach incorporates the cognitive correlates approach, avoids the inadequacy of correlational methods, and models individual differences on various dimensions of cognitive functioning.…

Reports three experiments to test age-related difFerences in sentence memory arising from sources other than noncognitive factors. Age-related differences are discussed in terms of deficiencies at encoding and retrieval. (PMJ)

A two-year study randomly assigned children (K-grade 2) with advanced mathematical skills (n=276) to two groups, an intervention group reflecting a constructivist approach or a control. Boys gained more than girls on quantitative and visual-spatial measures in the control, whereas the intervention group made greater gains in quantitative measures…

Investigates target language variability between speaking and writing in the second language acquisition of non-native English speakers. Results reveal that as narrators advance in English proficiency, they develop more abstract content and reported style in speech and writing and that speech and writing become more interactive. (28 references)…

Compared and contrasted are the concepts intuition and logic. The ideas of conceptual thought and algorithmic thought are discussed in terms of the world as a labyrinth, intuition and time, and the structure of knowledge. (KR)

Discussed are some situations students face that result in cognitive conflict, possible sources of these conflicts, and strategies which students use to resolve, remove, or circumvent them. A global account for observed systematic errors is offered based on a general problem-solving rule called the "Matching Rule." (KR)

Analysis of the relative contribution of age, gender, and verbal and mathematical reasoning abilities (measured by subtests of the Scholastic Aptitude Test) as predictors of success in accelerated secondary science courses found that a composite of verbal and mathematical reasoning ability was the most powerful predictor and verbal reasoning…

A teaching experiment with six third graders to analyze their ways of operating while solving fraction tasks. Children's quantitative reasoning with fractions was based on their quantitative reasoning with natural numbers. Presents the constructive itinerary of one of the most advanced children in the group. (Contains 44 references.) (Author/MDH)

Reports a study of 913 Israeli students in grades 7-12 from randomly chosen heterogeneous homeroom classes to investigate students' Piagetian cognitive levels using a video-based test. Results indicate that less than 50 percent of high school students have mastered formal operational reasoning. (MDH)
