Assesses the subject-matter competence in physics of inservice junior secondary science teachers in Hong Kong. Concludes that teachers lack subject-area knowledge. Discusses general implications for educational improvement. Contains 41 references. (DDR)

Grade five students' (n=58) conceptual understanding of plate tectonics was measured by analysis of student-generated summaries and diagrams, and by posttest assessment of both the spatial/static and causal/dynamic aspects of the domain. The diagram group outperformed the summary and text-only groups on the posttest measures. Discusses the effects…

Focuses on cognitive and affective changes that occurred in one student during the study of heat and temperature. Initially the student's conceptual framework was undifferentiated with regard to heat and temperature; however, course activities and concomitant use of concept substitution helped the student differentiate these concepts and integrate…

Describes a theoretical framework based on cognitive/developmental research. Argues that science learning is a gradual process during which initial conceptual structures based on children's everyday experiences are continually restructured. Contains 46 references. (DDR)

Reports on four models that show a possible pattern of progression that may be related to individual acquisition of conceptual knowledge about electricity. Contains 45 references. (DDR)

Attempted to examine the process of conceptual-change teaching through an Internet discussion, part of a distance-education teacher-training course, involving approximately 40 teachers. The prior beliefs of these teachers about science and science teaching may have hindered change and limited their willingness to explore the designated subject on…

Examines children's (n=306) drawings of a river basin to determine their understanding of scientific concepts related to the water cycle. Presents exemplars of five levels of understanding and analysis of the drawings' orientation and content. Contains 24 references. (Author/WRM)

Demonstrates the need for a process-oriented, constructivist approach to understanding infants' categorization abilities. Suggests that emphasizing the distinction between perceptual and conceptual categorization has been an obstacle to forging an approach. Proposes a more microanalytic consideration of features available to infants at different…

Three longitudinal studies examined means-ends behavior of 6- to 8-month olds. Found that intentional means-end behavior increased between 6 and 7 months, with 7-month olds' performance influenced by the presence of a toy on the cloth. Performance was the same when cloth was attached to or separate from the toy. By 8 months, infants adjusted…

Proposes that educators answer the question "What is social studies?" by utilizing normative methodology where a concept, in this case social studies, is evaluated and then modified to develop an applicable definition instead of implementing either a descriptive or conceptual methodology. Provides guidelines for arriving at applicable definitions…

Examines the extent to which science education graduate students enjoy a well-articulated position on the compatibility of science and religion and, as a result, are comfortable with their espoused views and plans for the role of religion in classroom discussions. Examines changes in students' mental states as a form of conceptual change after a…

Investigates children's development of causal explanations of success and failure. Compares two measures of causal attribution to show that the use of unipolar scales best depicts differences in causal factors used by children. Explores two hypotheses about the impact of normative context on the development of causal differentiation. (DSK)

Argues that students are conditioned by years of multiple-choice testing to use only simple recall and view knowledge as an uncataloged museum full of independent facts that are collected, recited, and left to gather dust. (DDR)

Studies a teacher's role and actions in a science learning community. Interprets two teaching episodes that illustrate how the teacher helps a group of students transform their understanding of electrical circuits. Contains 26 references. (DDR)

Discusses the development of multiplicative and divisional schemes within a constructivist framework. Illustrates child thinking and child methods relative to the meanings of these operations using interviews with children. Compares the constructivist perspective on the development of meanings of multiplication and division to what is found in…
