This paper addresses a problem that greatly complicates the implementation of dialogic educational approaches in schools: the dilemma between driving children's talk towards normatively accepted conceptions and, at the same time, avoiding the introduction of these normative conceptions into the dialogue by the teacher. I argue that this dilemma is…

It is urgent that we re-examine models of knowledge and knowledge-making within the university, at this time of open learning and deregulated multi-million dollar and euro open science hubs and portals. For otherwise, we are bound into "crude" instrumentalism, "delivering" "knowledge packets" rather than seeing our…

This article brings together, summarizes, and comments on several threads of research that have contributed to our understanding of the challenges that novice programmers face when learning about the runtime dynamics of programs and the role of the computer in program execution. More specifically, the review covers the literature on programming…

Radical constructivists advocate discovery-based pedagogical regimes that enable students to incrementally and continuously adapt their cognitive structures to the instrumented cultural environment. Some sociocultural theorists, however, maintain that learning implies discontinuity in conceptual development, because novices must appropriate expert…

Pressures for change in the field of teacher education are escalating significantly as part of systemic education reform initiatives in a broad spectrum of economically developed and developing nations. Considering these pressures, it is surprising that relatively little theoretical or empirical analysis of learning and change processes within…

This paper presents a method of assessment on how Human-Computer Interaction (HCI) and animation influence the psychological process of learning by comparing a traditional web design course and an e-learning web design course, based on the Change of Internal Mental Model of Learners. We constructed the e-learning course based on Gagne's learning…

The use of structural equation modeling is discussed in testing a range of theories of learning and cognition involving the concept of a hierarchy of variables of increasing complexity. To illustrate this approach, one method is applied to Bloom's taxonomy to test the theoretical assumption of hierarchical organization. (Author/MSE)

Via computational media, humans are entering a fifth stage of cognitive development leading to a virtual culture. This culture is seen as replacing the writing-based theoretic culture. Background information about the first four stages of mental evolution or cognitive development is provided. It is suggested that the evolutionary perspective needs…

This paper contains the comments of a discussant reviewing the paper, "The Role of Visual Representations in the Learning of Mathematics" (Abraham Arcavi). A research-based evaluation is made that focuses on the ideas of stochastics and the epistemological triangle. (Contains 28 references.) (DDR)

The unquestionably central role of physics in the development of scientific literacy is undermined by its perceived difficulty. An investigation of high school students' use of the concepts of momentum and force suggests that, in the case of mechanics, the reason for physics' unpopularity and image as a "hard" subject is largely due to an…

This paper gives a brief introduction to a discipline called the cognitive science of mathematics. The theoretical background of the arguments is based on embodied cognition and findings in cognitive linguistics. It discusses Mathematical Idea Analysis, a set of techniques for studying implicit structures in mathematics. Particular attention is…

Compared the effects of constructivist instruction and instruction based on texts and demonstration on third-graders' conceptualization of force. Found that constructivist instruction was more effective. Patterns of reasoning related to force were identified in levels of conceptualization. (JPB)

During the past 15 years, physics education research has revealed many surprising things about the difficulties introductory physics students have in learning physics. At the same time, the ongoing revolution in information technology has led to new tools for creating innovative educational environments. In response to these two developments, a…

This paper explores the nature of content and language across the curriculum in relation to the Targets and Target-Related Assessment (TTRA) initiative. The TTRA is an assessment initiative designed to improve the quality of individual learning from Primary 1 to Secondary 5 in Chinese, English, and Mathematics in Hong Kong. A picture of content…

Perspectives on the need for consistency in considering the promotion of conceptual change in science students and teachers (and in some circumstances, researchers) are presented in this paper. The parallels between the consequences of this consistency and the literature on educational change are also highlighted. A particular focus is directed to…
