Geometrical notions and properties occur in real-world problems, thus Geometry has an important place in school Mathematics curricula. Primary school curricula lays the foundation of Geometry knowledge, pupils learn Geometry notions and properties by exploring their environment. Thus it is very important that primary school teachers have a good…

Do we perceive correctly whether a 2-D object is balanced or unbalanced? What would be the cause of biased equilibrium judgments? In two psychometric studies, we varied independently the characteristics of the objects and the equilibrium states. First, we observed that observers were excessively sensitive to the eccentricity of the object top.…

The purpose of this study was to investigate the effects of a Computer-Assisted Instruction designed according to 7E model of constructivist learning(CAI7E) related to "electrostatic'' topic on physics student teachers' cognitive development, misconceptions, self-efficacy perceptions and attitudes. The study was conducted in 2006-2007…

This ERIC Digest concerns the constructed knowledge (also called nave knowledge or prior conceptions) held by students and the changes required to alter students' framework to understand and believe the true science concepts involved. This process is called conceptual change. Theoretical framework of conceptual change, what exactly is conceptual…

Interviews with 4- to 8-year olds indicated that children's understanding of how it is that they can see object develops gradually. This article presents a map of this development in terms of two distinct modes of cognitive functioning, the ikonic mode and concrete symbolic mode, drawn from the interviews and the SOLO (Structure of Learning…

Recently, "Developmental Psychology" published 2 articles on the shape bias; both rejected the authors' previous proposals about the role of attentional learning in the development of a shape bias in object name learning. A. Cimpian and E. Markman (2005; see record EJ733667) did so by arguing that the shape bias does not exist but is an…

The results of a study of the meiosis models utilized by individuals at varying levels of expertise while reasoning about the process of meiosis are presented. Based on these results, the issues of sources of misconceptions/difficulties and the construction of a sound understanding of meiosis are discussed. Five individuals from each of three…

In the May 2001 issue of "Educational Researcher," Michael Glassman proposed several commonalities in the thinking of John Dewey and Lev Vygotsky. However, in addition to general problems in the article (misstatements about scholars' writings and a reliance on unsupported inferences), the discussion misconstrues major concepts and topics addressed…

The science learning cycle developed by Robert Karplus and others in the 1960's has been a useful model for many science teachers and researchers. This model stresses the use of structured inquiry to organize knowledge acquisition and problem solving. Recent research in the cognitive science tradition, however, has shown that learning and problem…

This study observed and documented the changes of college students' notion of mathematics functions in a virtual environment that integrated a synchronous and asynchronous Computer Mediated Communication system. Four Arizona State University undergraduates were teamed into pairs and solved function problems in the virtual classroom over a one…

Describes the problem-solving behaviors of six novice subjects attempting to solve an electrostatics problem in calculus-based college physics. The level of qualitative thinking exhibited by these novices was determined. Sound procedural knowledge and problem representation were suggested as an integral part of skilled problem solving in physics.…

Concepts used by two classes of grade eight students, one advanced and the other average, to explain the changes that occur when water is heated to boiling are presented. Little difference was found between groups in terms of the personal misconceptions used to explain boiling. The changes that take place in conceptual knowledge immediately after…

Examined are first-year medical students' (n=160) explanations of complex concepts in cardiopulmonary physiology following a lecture series. The results revealed systematic misconceptions by the students in developing a pathophysiological model of the problem. The implications for science instruction within a medical curriculum are discussed.…

Presents research on different techniques to determine the level of understanding among middle school students regarding the phases of the moon. Quotes student responses to provide some insight into students' level of understanding of general knowledge about the moon, moon phases, and modeling the phases. Presents implications for teachers.

Identifies and describes the problems students have with the concept of neutralization. Analysis of over 7,500 students' answers to test questions over neutralization showed that many students understand the concept in its original meaning. Students assumed that in any neutralization reaction a neutral solution is formed, even if a weak acid or…
