The literature on gestures describes how they often comprise iconic, deictic and metaphoric dimensions, but the interplay between these dimensions can be very subtle and nuanced. Due to the abstract nature of the subject, the use of gestures in the learning of mathematics means that the metaphoric dimension is often prominent. However, iconic and…

According to our approach to mathematics education, the optimal aim of the teaching of mathematics is to assist students in achieving efficient mathematical work. But, what does efficient exactly mean in that case? And how can teachers reach this objective? The model of Mathematical Working Spaces with its three dimensions--semiotic, instrumental,…

A variety of practices and specialised representational systems are required to understand, communicate and construct molecular genetics knowledge. This study describes teachers' use of multimodal representations of molecular genetics concepts and how their strategies and choice of resources were interpreted, understood and used by students to…

The aim of this study is to analyze and document the extent to which high school teachers rely on a set of technology affordances to articulate epistemological and cognitive actions in problem solving approaches. Participants were encouraged to construct dynamic representations of tasks and always to look for different ways to identify and support…

When trying to help teachers cope with the critical situations they face in classrooms, public policies are mainly concerned with improving initial teacher training. I claim in this article that the role of lifelong learning should no longer be undermined and that the design of teachers' training should be supported by a thorough examination…

Reports and surveys by the U.S. government and international organizations have repeatedly acknowledged the achievement problem in math in K-12 regardless of various efforts (e.g., by the U.S. Department of Education) to diminish it. To address the problem in math achievement in K-12, teachers, scholars, and the U.S. government have developed…

In this article I present some results from a 5-year longitudinal investigation with young students about the genesis of embodied, non-symbolic algebraic thinking and its progressive transition to culturally evolved forms of symbolic thinking. The investigation draws on a cultural-historical theory of teaching and learning--the theory of…

Recent scholarship on secondary reading calls for a shift from teaching generic literacy strategies to teaching discipline-specific language and literacy practices (Fang & Schleppegrell, 2008; Moje, 2008; Shanahan & Shanahan, 2012). This call for disciplinary literacy instruction (DLI) reflects the growing recognition that literacy…

In this article, we describe a programme of qualitative research and interpretive analysis around an approach to foreign language pedagogy that aimed to develop learners' symbolic competence through experience with and examination of the signs in acts of communication. Learners were presented with the problem of visually representing the abstract…

Cognitive and conceptual uncertainties are critical elements in geology from the earliest data collection stage to concluding interpretations. How a geologist conceptually weighs the importance of various data greatly influences final interpretations. In order for the process of data selection and interpretation to be transparent and repeatable,…

This study investigates how two groups of bilingual algebra students reasoned about rate, slope, and linear functions during peer discussions. This investigation brings together and advances research that investigates issues at the intersection of collaborative learning, algebraic reasoning, and the use of mathematical discourse practices. A…

With contributions from leading scholars, this compelling volume offers fresh insights into literacy teaching and learning--and the changing nature of literacy itself--in today's K-12 classrooms. The focus is on varied technologies and literacies such as social networking sites, text messaging, and online communities. Cutting-edge approaches to…

New trends in teaching EFL in Europe are compiled and evaluated from various national and international research studies. Proposals for the integration of the semantic syllabus are emphasized. A movement towards rhetoric is found. (MS)

This article looks at the relevance of linguistic and psycholinguistic studies to mother tongue instruction. Particularly, the semantically-oriented research of higher level units of language and speech, is considered. As some Estonian studies imply, there are indications that the application of psycholinguistic research in teaching practices…

Exploring many possible relationships among language, thought processes, and education, this book is designed to synthesize modern views of language and linguistics, literature and semiotics, and thinking and knowing that are pertinent to education. It develops theoretical positions about language and thinking in school, proposes practical…
