This paper presents a case study of the process of conceptual change in six-year-old children. The process of conceptual change in learning about floating and sinking is described from two different viewpoints: how the children's conceptions change during the instructional process, and how the social discussion during the experimental exploration…

Research indicates that young children, unlike adults, have a generalized tendency to view not only artifacts but also living and nonliving natural phenomena as existing for a purpose. To further understand this tendency's origin, the authors explored parents' propensity to invoke teleological explanation during explanatory conversations with…

This article explores the effects of certain discourses as they relate to sexual harassment in a Swedish higher education setting. Using a semiological perspective, the author analyzes notions of existence, range, prevention, and stability in order to demonstrate the way they aim at signifying a limited and, from a bureaucratic point of view,…

The question asked by this study was whether information on play behaviour of young children at-risk of learning difficulties could act as a diagnostic means of investigating emerging learning difficulties. A sociocultural perspective was taken to examine the role of interaction during the play of students in a regular primary school and in a…

In this paper we propose the construct of discursive identity as a way to examine student discourse. We drew from the work of Gee (2001, Review of Research in Education, 25, 99-125) and Nasir and Saxe (2003, Educational Researcher, 32(5), 14-18) to consider the multiple contexts and developmental timescales of student discursive identity…

The specific purpose of this article is twofold. First, the article addresses critical teaching and learning evident in two generations of one nuanced Black family, the Foresight family, who appear to be surviving and thriving during and after the Freedom of Choice era of rural public schooling. The phrase "nuanced Black family" is…

Given many researchers' concern with multicultural approaches to art education and the fact that an increasing number of arts and arts-related courses are taught online, the authors explore theoretical considerations for researching multicultural arts courses delivered entirely over the Internet. Specifically, they maintain that such researchers…

This article focuses on the kinds of conceptual changes that occur when students have to deal with negative numbers in elementary algebraic operations. Interviews were carried out with twelve 8th-grade level students who were selected on the basis of their results in a test where they were required to reduce polynomials. The questions applied to…

Acquiring proficiency in different discourse genres involves an awareness of which syntactic structures are the most appropriate to the communicative context and purpose. This article examines two scientific research genres--conference proceedings articles and conference presentations--and compares the syntactic behaviour of a group of native…

A key to improving urban science and mathematics education is to facilitate the mutual understanding of the participants involved and then look for strategies to bridge differences. Educators need new theoretical tools to do so. In this paper the argument is made that the concept of "boundary spanner" is such a tool. Boundary spanners…

The following discourse seeks to characterize and to outline research from the field of Special Education. The research tradition in this field is ample, both at theoretical and especially practical levels, but unbalanced in terms of research and meta-research. Such an imbalance can be attributed to (among other possibilities) the lack of…

The present article examines one property of bilingual speech--convergence--and strives towards explanatory depth by attending to the insights of the antecedent research in formal linguistics, psycholinguistics, and sociolinguistics. In particular, the paper adopts as a point of departure (and further substantiates) the argument that convergence…

Initiation, response and follow-up (IRF) exchanges produced by a student and his tutor in an internet-based tutorial interaction have been analysed in terms of the multifunctional characteristics of each utterance. Different functions, related to different purposes, were observed in the IRF moves performed by the student. The control over the…

This article draws on the understanding of the lives and experiences of two Somali women, as case studies, to examine the relationship between identity, work and language learning. It begins with a brief discussion of embodied knowledge, with a view to exploring how "know how" intersects with literacy and identity. The article then moves…

For airline pilots, the call of "checklist complete" is officially prescribed talk to claim that the crew's joint conduct of a checklist is over, and the task can be understood as closed. However, very often this call is not the final talk for the task. This paper uses naturally occurring data, transcriptions of pilots interacting on actual…
