This study focused on the validation of Generalizable Reasoning Skills assessment instruments with students with disabilities in secondary vocational programs. Results indicated that student self-ratings, teacher ratings, and a performance test were internally consistent and precise measures of reasoning skills for some uses but that most…

The reasoning abilities to be expected of the concrete operational and formal operational student, the percentage of secondary science students that are capable of each type of reasoning pattern, and effective strategies to teach science to concrete reasoners are described. Implications for curriculum development are discussed. (KR)

Beginning geometry students misunderstand the requirements of formal proof because of confusion between deductive reasoning and argumentation. Presented is a cognitive analysis of deductive organization versus argumentative organization of reasoning and the applications of this analysis to learning. Implications of a study analyzing students'…

Examples of high school case studies are used to illustrate prototypical mathematical images and the use of imagery in metaphoric and metonymic ways in mathematics. Discusses pattern imagery and other types of imagery as central components in a model of mathematical reasoning. (34 references) (MDH)

The objectives of this study were to develop a method for scoring the level of abstraction (LOA) of science reading material and explore its relationship with other methods for assessing curriculum materials. LOA is defined as the ratio of the nonconcrete concepts to the total number of concepts in a written passage expressed as a percent.…

The purpose of this study was to examine the effects of three instructional methods and conceptual systems orientation on achievement in a freshman general chemistry laboratory course. Traditional approach, learning cycle, and computer simulations are discussed. (KR)

The Wechsler Adult Intelligence Scale-Revised (WAIS-R) and the Cognitive Test for the Blind were used to compare verbal and nonverbal abstraction ability of adults who became blind before age 2 or after age 5 (when expressive language would have been developed). No significant differences were found, but variability of scores on the WAIS-R…

Investigates different approaches of students from different cultures to problems and problem-solving strategies. Suggests ways to encourage students to use algebraic strategies. Provides some action research ideas for teachers to try in their classrooms. Contains 11 references. (ASK)

Describes a study of college students that investigated whether various types of visual illustrations influenced abstract concept learning when combined with audio instruction. Discusses results of analysis of variance and pretest posttest scores in relation to learning performance, attitudes toward the computer-based program, and differences in…

Describes several short geometry tasks that go beyond the simple recognition of figures and properties. Presents scoring rubrics and questions that might be useful to middle school teachers developing short open-ended questions that encourage and assess students' thinking. (ASK)

Suggests that while doubting that the dichotomy introduced by Subbotsky can cover the entire domain of motivation, he should applaud the emphasis on the neglected but critical importance of motivation in developmental psychology, and the attempt to distinguish different types of motivation, even as contributors to a single behavior.

As educators of both preservice and in-service teacher education students, 1 of the key questions we ask ourselves is how to prepare White students in rural areas of the United States to meet the needs of increasingly diverse populations of students. In this article, we discuss the conflicting research on how to meet goals of multicultural teacher…

A classroom cognitive intervention model for adolescents and adults who are deaf is described. The model provides mediated learning experiences whereby a person assists the learner in interpreting experience and learning problem-solving strategies. The program, entitled instrumental enrichment (IE), is based on the following principles: IE uses a…

A study investigated the relationship between formal and conversational logic. Thirty-two male and 32 female college students evaluated the conclusions of conditional syllogism and participated in an interview adapted from Deanna Kuhn's (1991) monograph, "The Skills of Argument." Students were asked to provide explanations for several…

This paper examines the mathematical conversations of middle school students as they use computer-mediated graphic representations to construct a shared understanding of the basic concepts of probability under two conditions. The first condition used graphical representations to depict important abstract relationships visually, and the second…
