Chemistry is considered a difficult subject by most students. Its difficulty lies in Chemistry's complex and abstract nature. This highly abstract nature requires constant interplay and coordination between the macroscopic, particulate, and symbolic representations. Experts can successfully navigate the various representations without overloading…

This article investigates how social inequality is reproduced through the recontextualization of mathematics pedagogy, using Dowling's social activity method as an analytical framework. The study identifies the selection and transmission of pedagogic messages as a potential pathway. Findings indicate that teachers in upper-stream schools favour…

There is growing interest in implementing reform-based lab courses in undergraduate physics that are student driven rather than instructor driven. In these courses, students develop and carry out experiments while simultaneously reasoning about their hypotheses, data collection procedures, collected evidence, and the relevant physics content.…

In this study, I use a systemic functional linguistics approach to examine mathematics classroom discourse with the aim of providing a plausible explanation of how students could actively participate in productive classroom discussions without adopting ways of reasoning that were accepted in the classroom community. In this way, I work in the…

James Moffett's "Teaching the Universe of Discourse" set out an agenda for the study of development in writing, which influenced James Britton's work in the UK. Subsequently, however, the work of both these thinkers was largely set aside in the approach to writing taken by national strategies in England. In this article, we trace the…

This paper uses data from two mathematics lessons to explore the nature of progressive discourse and examine critical features of teacher actions that contribute to mathematics classrooms functioning as communities of inquiry. Features found to promote progressive discourse include a focus on the conceptual elements of the curriculum and the use…

This submission contains the Proceedings of the 2008 Annual Meeting of the Canadian Mathematics Education Study Group (CMESG), held at the Universite de Sherbrooke in Sherbrooke, Quebec. The CMESG is a group of mathematicians and mathematics educators who meet annually to discuss mathematics education issues at all levels of learning. The aims of…

Students who are taught to understand and apply Korzybski's uses of semantics to their writing will learn to write more concretely. As students locate words and descriptions vertically on Korzybski's scale of abstraction levels, they will become able to perceive how meanings change when descriptions become either more general or specific, to…

Perspectives that underlie a study of scientific reasoning of elementary students with mild mental retardation (EC 612 096) are provided. Epistemological issues that appear to shape knowledge of special education are addressed, specifically "constructivism" versus "behaviorism" and the relative worth of "constructed" versus "instructed" knowledge.…
