The purpose of this research was to find the relation between the level of cognitive conflict and students' conceptual change. In this study, 30 Korean high school students were selected from 450 10th graders by examining the pretest results. To create students' cognitive conflicts, two different strategies were used to foster anomalous…

Diversity is an idea that merits closer critical analysis. Many efforts to support diversity are framed by discourses grounded in conceptualizations of culture, difference, and identity that further the status quo, not multicultural understanding. Schools need a strategy of teaching and learning about differences that radically challenges people's…

Suggests that the cross product of two vectors can be more easily and accurately explained by starting from the perspective of dyadics because then the concept of vector multiplication has a simple geometrical picture that encompasses both the dot and cross products in any number of dimensions in terms of orthogonal unit vector components.

Examines student teachers' understanding of the concept of force using a two-part written questionnaire. Findings indicate that there is a serious discrepancy between student teachers' understanding of force and the accepted scientific view. Contains 20 references. (JRH)

Investigates 49 preservice elementary teachers' conceptions of what causes the seasons using both a written procedure and a procedure that used models with verbal explanations. Results suggest that preservice elementary teachers are likely to show a high frequency of alternative conceptions of what causes the seasons and these conceptions are not…

Analyzes conceptions of energy of physics students' in a pre-service teacher training program. Findings indicate that the students are considerably anthropocentric in their associations, their choice of pictures, and their alternative conceptions and hold a number of different, alternative conceptions when describing physical situations. Contains…

Describes basic misconceptions about the origin of elements and forms of matter found in chemistry texts that need modification in light of modern observational data and interpretations given in astronomy. Notes that there are forms of matter other than elements and compounds. Confounding examples from astronomy include white dwarfs, neutron…

Examines the potential of global environmental issues as starting points for learning science by studying the preconceptions of children aged 12-13 about the nature, functions, and vulnerability of the ozone layer. Results indicate that children are familiar with the location and nature of the ozone layer but less informed about its magnitude and…

Reviews current literature related to the science achievement "learning gap" between Chinese and U.S. students. Presents an empirical assessment based on a more representative database from both countries. An extended mid-1980s study (the Second International Association for the Evaluation of Educational Achievement Study, or SSIS),…

Uses a test to assess teachers' science knowledge and understanding and monitors change over two years of a primary science in-service program in 31 schools. Despite moves to improve primary science teachers' subject knowledge, many still held typical misconceptions. Concludes that teachers need a thorough understanding of interrelated concepts…

Educational administration as a scholarly discipline is dominated by a modernist world view encapsulated in a positivistic "reality" and legitimate, "factual" knowledge base. The postmodern critique of positivism has called the basic premises of foundational legitimacy into question and represents the field's most serious…

Argues that the challenge for teachers of algebra in Australia is to find ways of making the structural aspects of algebra accessible to a greater percentage of students. Uses the zero product principle to provide an example of a common student error grounded in the difficulty of understanding the structure of algebra. (DDR)

Discusses a commonly held misconception that in the throwing of two dice, if a total of seven does not come up for a period of time then its appearance is imminent. Describes an experiment to disprove the misconception and includes a discussion of the theory that frames the results. (DDR)

Presents a new research-based course on quantum mechanics in which the conceptual issues of quantum mechanics are taught at an introductory level. Involves students in the discovery of how quantum phenomena deviate from classical everyday experiences. (Contains 31 references.) (Author/YDS)

Examines the author's discovery of elementary students' science misconceptions derived from the books she chose to share as read-alouds. Identifies three intertwining elements that might have led intelligent, curious young learners to create impossible science from these read-aloud sessions. Uses these three elements to organize personal…
