States unequivocally that the classification of humans into races has no validity within the discipline of biology. Maintains that such classification is strictly cultural and any attempt to discern differences in cognitive or other abilities among populations must confront the limits of scientific knowledge. (MJP)

Examines some of the misconceptions about the nature of critical thinking. Focuses on the characterization of critical thinking in terms of processes or skills and the separation of critical thinking and knowledge. Offers a different conception of critical thinking. (Contains 46 references.) (DDR)

Cites the misconceptions that students beginning the study of electric circuits often have about electricity. Explains the use of capacitors with circuits of batteries and light bulbs to introduce electrostatic forces and help to alleviate the problem of misconceptions. (RT)

Reported are the differences in the understanding of concepts involved in photosynthesis and its role in ecology between students who had studied advanced biology and those who had not. Reports that the less experienced students had a poorer understanding of autotrophic respiration and energy aspects of photosynthesis. (CW)

Examined the effects of an instructional method used to remedy students' difficulties caused by fragmented and incorrectly interpreted knowledge. Described the method using explicit concept-interpretation procedures. Finds that the method helped to revise students' deficient prior knowledge about acceleration, and helped them to interpret it…

Describes one mechanism by which prospective science teachers are socialized into the teaching profession prior to their student teaching experience. A Discrepant Events Share-a-thon is conducted by prospective middle school and high school teachers at the Georgia Science Teachers Association annual meeting. (LZ)

Proposes analogy as the central mechanism of knowledge acquisition in formal domains. Discusses experimental data on preschoolers' knowledge of one-to-one correspondence and college students' understanding of force decomposition. Suggests that a knowledge base domain is a thematically organized knowledge structure and that thematic relations in a…

Describes a qualitative study in which eight elementary school teachers read research articles in children's science and were interviewed. Results fall in three categories: comments relating to the teachers' need to verify the findings of research reports, expressions of self-doubts and questions raised as teachers read the articles, and…
