Discusses ideas about the particulate nature of matter and assesses the extent to which these represent a compromise between scientific and educational considerations. Analyzes relations between the particulate nature of matter in science and science education in an attempt to understand children's inclination to attribute all kinds of macroscopic…

Examines the predator-prey relations and the preconceptions held by children (n=506) on the construction of food chains. Results show that the classification of herbivores and carnivores is based on children's preconceptions of size and ferocity and sheds light on the difficulties students have at higher education levels in the resolution of food…

Deals with the problem of the proper interpretation of discourse between students and teachers in classrooms. Presents several interpretations of a concrete classroom protocol in terms of misconceptions. Draws on Davidson's principle of charity and distinguishes between belief and meaning to present an analysis that interprets the discourse…

This review of literature focuses on three decades of research related to precollege student understandings about the nature of science. Although the majority of studies show that student understandings are less than desirable, there is research that indicates that student conceptions are acceptable. (PR)

Criticizes an article by Browning and Lehman (1988) for (1) using "gene" instead of allele, (2) misusing the word "misconception," and (3) the possible influences of the computer environment on the results of the study. (PR)

Authors respond to criticisms by Smith in the same issue and defend their use of the term "gene" and "misconception." Authors indicate that they did not believe that the use of computers significantly skewed their data concerning student errors. (PR)

Explores school districts' responses to state science standards and examines the ideas about science education that district policy makers construct from these standards. A cause of failing to implement state science standards, rarely examined in the literature, concerns the ways in which local implementers miss or misconstrue the intent of policy…

Presented is a criticism of Lawson's (1988) article on the development of misconceptions of biological concepts. Lawson's response to this criticism follows. (CW)

Administered questionnaires to 35 science teachers to test the hypotheses that teachers holding constructivist beliefs are more likely to detect alternative conceptions, have a richer repertoire of teaching strategies, use more effective teaching strategies for inducing conceptual change, and report frequent use of effective teaching strategies.…

Argues that declarative writing about science that presents historical or biographical information incorrectly is not acceptable. (WRM)

This study focuses on the conceptions of trainee, primary, and subject teachers about three phenomena: the motion of objects, seasonal changes, and aggregate changes of matter. A total of 198 participants completed a questionnaire concerning two types of tasks. First, teachers evaluated the adequacy of a given explanation as compared to their…

Argues that assessment should be an integral component of the science curriculum and that assessment should assist students and teachers in accomplishing their goals. Points out the failures of the process-product models of school reform. (DDR)

Discusses a study which explored the possible value of the history of science to understanding student misconceptions. Focused on photosynthesis and examined relationships between students' conceptual difficulties and the transformation of concepts through time. Student responses suggest that the history of science can be used to anticipate…

This article aims to present the results obtained from science teachers about their attitudes toward students' conceptions and the use of teaching strategies based on these conceptions. The results may contribute to the planning of inservice courses. (Author)

This article reports on answers by children (grades 1-9, n=83) to oral and written questions concerning the phase change from liquid to gas. The development of concepts was followed, proceeding from concrete to abstract ideas. Many students were found to experience difficulties in problem solving even though they may have had the necessary level…
