Roth, Wolff-Michael; Hwang, SungWon – Journal of Mathematical Behavior, 2006
The notions of "abstract "and "concrete" are central to the conceptualization of mathematical knowing and learning. It is generally accepted that development goes from concrete toward the abstract; but dialectical theorists maintain just the opposite: development consists of an ascension from the abstract to the concrete. In this article, we…

Roth, Wolff-Michael; Hwang, SungWon – Journal of Mathematical Behavior, 2006
The notions of "abstract" and "concrete" are central to the conceptualization of mathematical knowing and learning. Much of the literature takes a dualist approach, leading to the privileging of the former term at the expense of the latter. In this article, we provide a concrete analysis of a scientist interpreting an unfamiliar graph to show how…

Roth, Wolff-Michael; Lee, Yew-Jin – Educational Research Review, 2006
Past educational improvement endeavors were fundamentally centered on the learner as an individual. This changed by the early 1990s after an increasing number of educators and researchers embraced sociocultural learning concepts such as "communities of practice," "communities of learners," and "knowledge-building communities." These ideas are…

Lee, Yew-Jin; Roth, Wolff-Michael – Journal of Workplace Learning, 2006
Purpose: The purpose of this paper is to highlight some methodological problems concerning the neglect of participants' voices by workplace ethnographers and neglect of the highly interactional and co-constructive nature of research interviewing. The study aims to use discourse analysis, to show the phenomena of workplace learning and expertise to…

Han, Jae Young; Roth, Wolff-Michael – Science Education, 2006
Thinking about macroscopic phenomena in terms of models based on the idea of microscopic particles (i.e., the particulate theory of matter) is one of the important goals for student learning in chemistry around the world. However, previous research suggests that students do not easily understand phenomena from a particle perspective, although such…

Givry, Damien; Roth, Wolff-Michael – Journal of Research in Science Teaching, 2006
Most studies about students' conceptions and conceptual change are based exclusively on the analysis language, which is treated as a tool to make private contents of the mind public to researchers. Following recent studies that focused on (a) language and discursive practice and (b) the pragmatics of communication that draws on talk, gestures, and…

Goulart, Maria Ines Mafra; Roth, Wolff-Michael – Journal of Curriculum Studies, 2006
One important challenge for researchers is to understand what happens inside classrooms that make the environment available for children's learning. This study develops the margin|centre dialectic as a general framework for describing participation of very young children in science-related activities. It employs a cultural-historical approach that…

Roth, Wolff-Michael; Tobin, Kenneth; Carambo, Cristobal; Dalland, Chris – Science Education, 2005
In coteaching, two or more teachers take collective responsibility for enacting a curriculum together with their students. Past research provided some indication that in the course of coteaching, not only the teaching practices of the partners become increasingly alike but also do unconsciously produced ways of moving about the classroom, hand…

Bowen, G. Michael; Roth, Wolff-Michael – Journal of Research in Science Teaching, 2005
The interpretation of data and construction and interpretation of graphs are central practices in science, which, according to recent reform documents, science and mathematics teachers are expected to foster in their classrooms. However, are (preservice) science teachers prepared to teach inquiry with the purpose of transforming and analyzing…

Tobin, Kenneth; Roth, Wolff-Michael – School Science & Mathematics, 2005
Over the past 7 years the authors have been involved in the development of a new model for the education of science teachers that has the potential to address teacher education in challenging urban settings characterized by problems such as teacher turnover and retention, low job satisfaction, and contradictions arising from cultural and ethnic…

Elmose, Steffen; Roth, Wolff-Michael – Journal of Curriculum Studies, 2005
Sociologists increasingly note that one lives in a risk society, characterized by the unpredictable consequences of techno-scientific innovation and production and by increasing complexity. Life in risk society, particularly in truly democratic societies, increasingly requires competencies not only to understand and change one's own circumstances…

Roth, Wolff-Michael – Mathematical Thinking and Learning: An International Journal, 2005
The power of mathematical inscriptions, such as graphs, is often attributed to the fact that they summarize a lot of information independent of their contextual particulars. There is evidence, however, that even quintessential experts and scientists have difficulties interpreting graphs when they are unfamiliar with the entities represented and…

Lee, Yew-Jin; Roth, Wolff-Michael – Journal of Workplace Learning, 2005
Purpose--Sociocultural learning theories, usually premised on participation in some community, explain workplace learning well up to a certain extent. The paper aims to extend beyond these and to account for learning in repetitive and mundane work environments from a dialectical perspective. Design/methodology/approach--Based on a longitudinal…

Pozzer-Ardenghi, Lilian; Roth, Wolff-Michael – Science Education, 2005
In some contexts, a photograph may be worth a thousand words. Previous research revealed a dialectical character of photographs: they simultaneously lack determinacy and exhibit an excess of meaning. The purpose of this study was to understand how, under this condition, high school students interpret photographs that were accompanied by different…

Boyer, Leanna; Roth, Wolff-Michael – Environmental Education Research, 2005
In this article we describe an instance of free-choice learning in the context of an eelgrass mapping and stewardship project (the "Project") that covers over 500 kilometers of coastline in British Columbia, Canada, and involves 20 volunteer groups. In this ethnographic case study we sought to (a) explicate the relationship between…
