Examined the influence of college students' expertise on use of multiple documents about a historical controversy. Found that strategies did not differ significantly across the groups of expert and non-expert students. However, evaluation of usefulness varied as a function of document type and students' expertise. Furthermore, novices and experts…

Describes a study of 32 University of Transkei (South Africa) freshmen's conceptualization of "limiting reagent," a basic concept in chemistry, based on student responses to two written test questions and clinical interviews. Results indicated that a high percentage of students had misconceptions and could not apply the concept…

Recent contributions from theory, research, and practice in second-language instruction are discussed in relation to mathematics education. Three methods of teaching and learning second languages are described--"Delayed Oral Production," the "Silent Way," and the "Counseling Learning/Community Language Learning." (KR)

Discussed are preservice elementary teachers' misconceptions and inconsistent beliefs about multiplication and division with decimals. Sources of inconsistencies and recommendations for overcoming inconsistencies are included. (KR)

Explores how constructivism is important to changes taking place in physics education, especially in curriculum development and teaching. Presents an example illustrating children's conceptions of light. Twenty-six references are listed. (YP)

Investigates whether elementary children can compare forces by comparing numbers of weights used in spring and balance problems. Reports that children did not identify weight and force, but they were able to use the ratio between the numbers of weights to compare forces. Suggests some instructional methods based on the findings. (YP)

Used are test and interview data to extract evidence as to what level tenth graders have coordinated the worlds of arithmetic and algebra and can move freely between them. More dissociation is shown than was expected. (Author/MVL)

States that students have misconceptions about the principles of mechanics internationally providing examples and two problems. Describes Nachtigall's program to train teachers and reports its application to classroom teaching. (YP)

A theory is proposed for how students develop competence with the written symbols of decimal fractions. Competence is viewed as the cumulative and sequential mastery of four separate cognitive processes. The theory was tested with small groups of students, most of whom were able to acquire the first two processes. (MNS)

Discusses some difficulties in teaching the concept of voltage to secondary school students. Presents and describes the content of a teaching sequence introducing voltage as a primary concept through relationships with other variables. Provides an example of the delivery of the teaching model. (YP)

Children's magical explanations and beliefs were investigated in two studies. Found that many four-year olds view magic as a plausible mechanism, yet reserve magical explanations for certain real world events that violate their causal expectations. Parents and culture at large may at first actively support magical beliefs whereas peers and schools…

Two lessons from comparable undergraduate courses in physics and engineering are analyzed to identify content, issues emphasized, and concepts used. Differences reflecting the pure nature of one field (physics) in contrast to the applied nature of the other are identified. Implications for classroom instruction and for research on college teaching…

Presents a sequence of hands-on activities to help students understand the concept of arithmetic mean and gain experience in using mathematical models. Students create models in the process of solving problems and communicate to the class the meaning attached to the models. (MDH)

Develops a conceptual framework for understanding contemporary race relations in the United States. The framework focuses on the critical components involved in the development and institutionalization of dominant-subordinate relationships. (GR)

Assists teachers involved in bilingual instruction in improving their understanding of two aspects of bilingual development: interlanguage and of code-switching. Both are natural and creative outgrowths of being bilingual, i.e., alternative forms created by the cognitive/conceptual synthesis of two languages. (30 references) (CK)
