Two studies were conducted to determine the effects of gender, reasoning level, and inductive and deductive computer-simulated experiments (CSE) on problem-solving abilities in introductory general chemistry. In the pilot study, 254 subjects were randomly assigned to control (computer-assisted-instruction tutorials), inductive or deductive CSE…

We examine a prospective high school teacher's instructional representations of rate of change and right triangle trigonometry to investigate his interpretation and understanding in relation to the development of proportional reasoning. Despite a constant effort by the subject to resort to "real life" examples in order to give meaning to his…

This bulletin offers guidelines to help parents and teachers improve the thinking skills of gifted children. It stresses the importance of encouraging thinking through the use of evocative questions, distinguishes between and defines critical thinking and creative thinking, and offers suggested questions to prompt either creative/divergent…

This paper explores a framework for research on the development of the angle concept based on theories of abstraction. The framework suggests that children initially acquire a body of disconnected angle knowledge situated in everyday experiences, group the situations to form angle contexts, and then form an abstract angle concept. The framework is…

Seventh- and eighth-grade students with learning disabilities (n=29) who reasoned through factual prose sentences did not recall more information than students who were prompted to try to remember the content after each sentence. However, students trained in thinking skills produced more correct explanations of the information than control…

This discussion of fostering recall and developing reasoning processes in students with mild disabilities considers the role of mnemonic strategies, similarities between mnemonic strategies and elaborative interrogation to facilitate information retrieval, constructivism and elaborative interrogation, and such problems as generalization and…

Presents examples where mathematical and physical reasoning complement each other in interpreting and analyzing some basic science concepts using proof by contradiction and contrapositive. Examples involve the rotation of the moon, the stability of electrons and protons, the electron's orbit about the nucleus, and the earth's liquid core. (MDH)

Features five activities to nurture "number sense," promote practice in mental calculations, and promote student self-confidence in mathmatical operations. These are "hands-off" exercises that are preparatory to calculator and computer use for math. (ET)

Describes the design of a computer-based problem-solving tool for teaching abstraction and classification to elementary school students. The task involves reasoning with attribute blocks. The software keeps a detailed trace of the student's actions, allowing teachers to provide intelligent feedback to the student. Results of a pilot study of the…

Examined inconsistencies in secondary school students' reasoning about the probability concept of equally likely events. Results of two studies suggest that the number of students who understand the concept of independence is much lower than the latest National Assessment of Educational Progress results indicate. (Contains 22 references.) (MDH)

Three experiments using university students explored what constitutes an event and what determines its boundaries. Results supported the hypothesis that sequences of stimuli repeating in different contexts are cut out to become cognitive entities ("things" with a beginning and an end) in their own right. Results suggest that the…

This article describes a problem-solving strategy unit to be used as a supplement to the regular mathematics curriculum at the primary level. Specific teaching steps and examples are given for three developmental stages of thinking: (1) concrete, (2) representational, and (3) abstract. (DB)

The cognitive factors that contribute to competence in the biological sciences were examined. The role played by cognitive style and analytical ability is discussed. The ability to abstract relevant information, evaluate it, and use it is affected by the skills of analysis and cognitive style. (KR)

Twenty-four sixth-grade children participated in clinical interviews on ratio and proportion before receiving instruction in the domain. Student thinking was analyzed in terms of mathematical components critical to proportional reasoning. Two components, relative thinking and unitizing, were consistently related to higher levels of sophistication…

The Matrix Analogies Test measures nonverbal ability of handicapped and nonhandicapped children, ages 5-17, in a culture-fair fashion. It assesses pattern completion, reasoning by analogy, serial reasoning, and spatial visualization, with a short form available as a screening instrument. This paper describes the test's administration, format,…
