Background: Engineering students commonly learn domain knowledge by engaging with visual representations of it. However, at times they have trouble accessing information from these representations due to the way information is encoded in features of the representation. Purpose: To describe how students engage with representation features, we…

Climate change is an important theme in the investigation of human-environment interactions in geographic education. This study explored the nature of students' understanding of concepts and processes related to climate change. Through semi-structured interviews, data was collected from 27 Secondary 3 (Grade 9) students from Singapore. The data…

Adult developmental mathematics students often work under great pressure to complete the mathematics sequences designed to help them achieve success (Bryk & Treisman, 2010). Results of a teaching experiment demonstrate how the ability to reason can be impeded by flaws in students' mental representations of mathematics. The earnestness of the…

Presents the results of a study that identifies misconceptions in chemistry by means of a two-tier diagnostic instrument. Data indicate that similar misconceptions are held by both Singaporean and Australian populations. Focuses on covalent bonding and structure. (DDR)

Supports the use of microanalysis of conceptual change as a tool for reconceptualizing the nature of students' knowledge-in-development and dissolving concept-misconception and expert-novice dichotomies. Contains 48 references. (DDR)

Presents a summary of teaching practices that are successful in promoting conceptual change based on a study of Grades 4, 8, and 10 and on the research literature. Proposes improvements in teaching methodology. Contains 31 references. (DDR)

Compares the ideas of young people about Newton's third law, focusing on youth of today and youth of the 17th and 18th centuries. Examines the use of Newton's third law in understanding impact phenomena in the 17th and 18th centuries. Contains 46 references. (DDR)

States that the shift in meaning of the Periodic Table to represent regularities in the electron distribution in the shells of atoms can result in confusion between elements and atoms. (DDR)

This paper examines the nature of physics students' knowledge, the means to identify alternative conceptions, and possible methods to overcome misconceptions. This examination is a survey of the techniques and ideas of a large number of researchers who are seeking their own solutions to this problem. An examination of the nature of knowledge…

Presents an account of one teacher's path to realizing the depth of intuitive beliefs about science. Organizes chemistry misconceptions into eight patterns of reasoning that include thinking rules and alternative conceptions. (DDR)

Investigates Grade 12 students' understandings of the nature of chemical bonds and the energetics elicited across five familiar chemical reactions following a course of instruction. Discusses the many ways in which students can misconstruct concepts and principles. Contains 63 references. (DDR)

Reconstructs students' and teachers' understanding of the structure of the atom based on a framework characterized by considering the history of science as competing research programs and by believing that some great scientific research programs progress on inconsistent foundations. Contains 107 references. (DDR)

Presents a framework characterizing cognitive models generated by sixth-grade students for simple opening/closing control mechanisms, like the elevator door. The students' conceptions, missing conceptions, and misconceptions are analyzed at three levels: device knowledge; perception of the control process; and perceptions of information flow. (LAM)

Identifies certain conceptions regarding the science content studied by students aged 9-11 years and develops a strategy for altering these conceptions. Reviews research on misconceptions and defines action research. (DDR)

Discusses the implications of a research study of more than 2000 students aged 11 to 15 that explored why the students interpret algebra in certain ways. Recommends strategies that can help teachers deal with prior knowledge that students may bring to their study of algebra. (DDR)
