Investigates the mediating effect of learner self-concept between conceptions of learning and students' approaches to learning using structural equation modeling. Results indicate that learner self-concept does mediate between conceptions of meaning and approaches to learning. Implications for teachers are discussed, with consideration given to…

Offers examples of what infants and toddlers might do in early childhood settings, how these behaviors are related to mathematics, and what teachers can do to encourage the natural mathematical interests of this age group. Asserts that teachers' interactions with children are vitally important to children's understanding of early mathematics. (KB)

Examines the effects of using a conflict map on 8th grade students' conceptual change and ideational networks about simple series electric circuits. Analyzes student interview data through a flow map method. Shows that the use of conflict maps could help students construct greater, richer, and more integrated ideational networks about electric…

Examines the relationships between organic chemistry achievement and a number of cognitive and noncognitive variables, and explores whether gender differences existed for any of these relationships. Concludes that general chemistry grade, ACT-math score, and motivation are significant predictors of organic chemistry achievement. Indicates gender…

Describes a calculator-based lesson designed to use technology as a tool to enhance students' conceptual understanding of functions. (KHR)

Explores challenges of learning to think about data as signal and noise. Examines the signal/noise metaphor in the context of three different statistical processes: (1) repeated measures; (2) measuring individuals; and (3) dichotomous events. Makes several recommendations for research and instruction on the basis of this analysis. (Author/KHR)

Describes one instructor's approach to incorporating simulations and classroom discussions into a differential equations course. Discusses subsequent effects on student learning attitudes and outcomes in conceptualizing and applying ideas regarding solutions to differential equations in this learning environment. Explores issues on…

Describes a method for teaching multiplication of fractions based on Piaget's constructivism. Instead of teaching the algorithm of multiplying the numerators and denominators, students are presented with many problems and ask to invent their own ways of solving them. (DDR)

This article attempts to clarify issues that were discussed in a previous article, which was written in response to an article that focused on connectionism and language transfer. (33 references) (CK)

Presents the view that deductive mathematical proof offers the purest form of how to distinguish right from wrong. Investigates students' understandings of proof and the proving process in mathematics. Contains 32 references. (DDR)

Claims that mind and mental objects form a societal mental structure enabling children to assimilate the society and become co-constructing members. Cites evidence that competence to create mental objects, symbols, and meanings separated from action is the evolutionary evolved human capacity for society and culture. Vygotsky's "natural"…

Considers the idea that concept mapping has applications beyond those associated with student assessment. Outlines further uses for concept mapping in the classroom along with suggestions for implementing this powerful tool. (DDR)

A study of the processes by which 24 grade-12 Australian physics students brought order to their observations and practices shows that the phenomena students construct from their laboratory work (not always accurate) develop from connections among the embodied practices of language and physical action, their world, and social relations. (SLD)

Considers the relevance of the points raised in the preceding articles in this issue to the sociolinguistic development of children with speech and language impairments. Notes that such children often have low self-esteem and that their inability to negotiate an identity for themselves through discussion with their peers may contribute to this…

Reports a study that tracks the changes in children's ideas about science and scientific concepts through the use of interviews and questionnaires. Students respond to seven questions about science learning, scientists, and their future relationship to science. (DDR)
