Meaning is one of the recent terms which have gained great currency in mathematics education. It is generally used as a correlate of individuals' intentions and considered a central element in contemporary accounts of knowledge formation. One important question that arises in this context is the following: if, in one way or another, knowledge…

We investigate the use and knowledge of graphs in the context of a large industrial factory. We are particularly interested in the question of "transparency", a question that has been extensively considered in the general literature on tool use and, more recently, by Michael Roth and his colleagues in the context of scientific work. Roth uses the…

How does the development and consolidation of perceptual, attentional, and higher cognitive abilities interact with language acquisition and processing? We explored children's (ages 5-17) and adults' (ages 18-51) comprehension of morphosyntactically varied sentences under several competing speech conditions that varied in the degree of attentional…

This article investigates very young children's use of a stylus-driven, electronic painting and drawing on the tablet PC. The authors compare their development in the use of this device with their use of other mark-making media, including those which derive from pencil and paper technologies and also with mouse-driven electronic paintbox programs.…

In this article the authors explore the relationship between concepts of identity and the purpose, process, and products of youth media arts organizations. Since the explicit mission of these organizations is to work with adolescents to explore and represent identities, the authors develop our understanding of how organizations conceptualize…

This qualitative study represents perceptions of students regarding campus environment and campus life at University College of the Fraser Valley (UCFV), a public four-year university-college located in British Columbia, Canada. Employing a unique methodology, referred to as reflexive photography, student participants were asked to photograph and…

The present study relates to a research line in didactics of science that focuses on the function that sign systems or semiotic modes have in communicative interactions in science classrooms. The study was conducted by 20 secondary and university science teachers who belong to the same research group LIEC ("Language and Science…

This article considers the discourse of teachers when content areas are taught through a second language. Bilingual discourse is discussed in the particular scenario of content and language integrated learning, CLIL, a paradigm growing in strength and popularity in L2 teaching across Europe. An examination of instructional discourse is carried out…

The Deese/Roediger-McDermott (DRM) paradigm was used to investigate developmental trends in accurate and false memory production. In Experiment 1, DRM lists adjusted to be more consistent with children's vocabulary were used with 2nd graders, 8th graders, and college students. Accurate and false recall and recognition increased with age, but…

Recent data suggest recovery of language systems but persistent structural abnormalities in the prematurely born. We tested the hypothesis that subjects who were born prematurely develop alternative networks for processing language. Subjects who were born prematurely (n = 22; 600-1250 g birth weight), without neonatal brain injury on neonatal…

Youngsters are increasingly using digital technologies through participation in informal settings. Schools, however, seem to be struggling with implementing digital technologies into formal school activities. With the impact of digital technologies, media education can be seen as an increasingly important "transactional learning space"…

In this qualitative study of mathematical discourse between elementary teachers, we examined linguistic invention and semantic warrant production as participants made successive attempts to communicate mathematical ideas. Linguistic invention is a creative practice of describing mathematics in terms of personal experience. We introduce semantic…

This article adopts an input perspective in examining a poverty-of-the stimulus (POS) learning situation in second language acquisition (SLA). Analysis of grammaticality judgement data from 81 English-speaking and 85 Chinese-speaking learners of Japanese isolates triggering input that informed English learners of subtle semantic properties of the…

After a review of semiotic theory, this paper describes an ethnosemantic study of a funeral home that demonstrates how semiotically identical codes structure a funeral director's understanding of his work and how semiotic research can reveal rules by which members of an occupational culture generate meaning. (MJL)

Describes the application of semiotic concepts and tools to information-retrieval systems design, which is viewed as a social practice in which the main disjunction is between the two conflicting acts of detonation and prescription. These two conflicting language games are discussed within the framework of the Okapi information retrieval system.…
