Concept mapping was used to tap the conceptual disciplinary (science subject) knowledge and pedagogical knowledge of seven biology and six geography teachers with short or long teaching experience. Results indicate that knowledge in both areas is unsatisfactory, experience does not improve the knowledge, and teachers mastered disciplinary…

Students of reasoning have long tried to understand how people revise systems of beliefs. This paper maintains that people often change their beliefs in ways driven by considerations of explanatory coherence. In this report, a computational model is described of how experimental subjects revise their naive beliefs about physical motion. First,…

Discusses the relationship of school size to understanding of scientific concepts. Results indicated that students in small high schools had fewer instances of understanding and more instances of misunderstanding of the concepts of diffusion and homeostasis. No difference was observed for concepts related to food production in plants and…

Discussed are possible reasons behind the inconsistencies in the learning of calculus. Implicated are students' beliefs, mathematical paradigms including concept image and concept definition, language use, and curriculum sequencing. (KR)

Discussed are the issues of inconsistencies and compartmentalization and the use of inconsistencies in the classroom. Included are discussions on paradoxes, the naive student, logical reasoning ability, and the development of the students' cognitive structures. (KR)

Discusses a system of classification for students' inconsistent ideas in mathematics, the sources of students' mathematical inconsistency, and instructional strategies for helping students to resolve apparent learning inconsistencies. Language, curriculum, and instruction are included in the discussion. (KR)

Discusses recent research in cognitive psychology that identifies how students are likely to respond when controversial issues are included in course content. Points out that controversial material may lead to misunderstandings and forgetting. Provides teaching ideas to enhance student learning and remembering, to deal with emotions, and to foster…

Many current studies have discovered that students tend to use either an Aristotelian or the Medieval impetus model rather than the Newtonian view in order to explain their experience. This preconceived knowledge may be important for students in learning mechanics. The purpose of this study was to identify and confirm the existence of a…

Noting that successful comprehension, problem solving, and decision making are dependent upon activation and appropriate application of relevant schemata of existing knowledge, this report examines the practice of oversimplifying information in the content areas to make teaching and studying easier, and the dangers inherent in doing so. The report…

In today's climate of content standards and high-stakes testing, science teachers are under more pressure than ever to focus on the "ready-made" knowledge of science content. Yet, science educators have long advocated a more balanced approach to science instruction, including emphasis on the processes by which scientific knowledge is produced, as…

Diagnoses of students' performance on procedural mathematical tasks need to display a certain level of stability and robustness if they are to be used as the basis for remediation, particularly with computer-delivered instruction. The purpose of this study was to compare two diagnostic approaches for describing students' (n=231) errors in algebra…

This uniquely comprehensive and current survey of the research in science education has been compiled by the most prominent experts in the field. More than a summary of findings, the content of this comprehensive single volume provides an assessment of the significance of research; evaluates new developments; and examines current conflicts,…

To investigate the origins and nature of intuitive obstacles affecting the learning of elementary probability theory, 618 Italian elementary and middle school students were interviewed about their methods of solution for several problems dealing with probability. The discussion focuses on four varieties of obstacles to learning prevalent within…

One hundred and forty students in grades 6 and 7 were asked to process 32 science statements. Half of the statements were consistent with their prior knowledge, whereas the remaining facts were inconsistent with it. Half of the students were instructed to read the sentences for understanding (reading controls). The remaining students were…

A diversity of themes are addressed in the papers presented in this document; they include new topic areas as well as concerns that have been cited in previous issues. The papers focus on such topics as: (1) problem solving; (2) cognition; (3) the learning environment; (4) energy education; (5) the use of diagrams; (6) scientific methodology; (7)…
