The effect of a relevant analogy and of subject visualization on the amount of cognitive capacity needed to process unfamiliar information about science was investigated. The dependent measure was reaction time on a secondary task while listening to six tape recorded passages about chemistry and physics in a 2 x 2 x 6 mixed design. The analogy…

The education of teachers involves three categories of knowledge: particularistic, technical, and liberal. These knowledge areas are explored and their association with field, laboratory and scholarly/scientific learning environments is discussed. (DF)

Suggests a framework for clinical teacher education (to be used in programs for prospective, beginning, and career teachers) that proposes context as a defining property and outlines seven critical features. Programs should be purposeful, participatory, knowledge-based, ongoing, developmental, analytical, and reflective. Includes 55 notes. (MLH)

Presented are the results of a study of high school and college students concerning their thinking about functions of the human body. It was shown that students' thinking could be positively changed over the short term from teleologic to mechanistic. Sample survey questions are included. (CW)

Examined the feasibility of using two microcomputer simulations to improve preservice elementary teachers performance in the formation and testing of hypotheses. Considers the effects of mode of computer instruction and cooperation on the acquisition of skills. (CW)

This manual describes two methods of assessing college students' conceptual structures in the interest of student evaluation. The focus is on the mental frameworks (conceptual structures) that enable students to remember and apply facts and theories. The guide offers two methods, the "ordered-tree" and the "fill-in-the-structure." An introduction…

Investigated are three misconceptions of probability and the differential effect of two activity-based instructional units. Response categories (law of averages, law of small numbers, and availability) are identified. Treatment differences (evaluation or no evaluation) appear to influence subjects' interpretations of the information. (YP)

Presented is an alternative method for analyzing the van Hiele level of students' geometrical reasoning. The accuracy of students' answers may afford a description of acquisition and/or expertise for each of the van Hiele levels simultaneously rather than the traditional assignment and evaluation of one level at a time. (JJK)

The two-part activity outlined in this paper reveals to undergraduate students that assumptions made in theory building remain unquestioned until one steps outside the initial realm of expectations, and that theories adopted have a demonstrable impact on behaviors. Part I defines a theory, describes the roles of assumptions and knowledge in…

This paper analyzes Bogdanov's theory of knowledge as found in philosophical dialogues and essays. The style of Bogdanov's writing and his ideas on philosophy, science, scientific constructs, truth, human knowledge, objectivity and ethics are discussed. These ideas are compared to the constructivist view of knowledge. (CW)

Discussed is a common error made by students in judging the distribution of the magnetic field of a circular loop along its diameter. Qualitative and quantitative explanations of the magnetic field distribution are presented. (CW)

The purpose of this study was to develop a procedure for the evaluation of M-demand of chemistry problems. It was shown that dimensional analysis upon the Neo-Piagetian theory of Pascual-Leone could help science teachers to understand the epistemological basis of their discipline. (CW)

A study documented 10 college students' understanding of the limit concept and the factors affecting changes in that understanding. Encouragement by the researchers for the students to change their common informal models of limit to more formal conceptions were met with extreme resistance. (Author/JJK)

Presents study results suggesting some malleability in learning strategies that flow from cognitive style. Examines the effects and practicability of restructuring training as a means of addressing individual learner differences. Reports that training enhanced performance on two dependent measures tasks. Concludes that field-dependent learners…

Contends that many students reject historical study because they see no connection between factual information and their own needs and interests. Suggests that this epistemology of the self can be used to analyze historical information. Recommends helping students see that historical fact is subject to individual and group interpretation. (CFR)
