In this dissertation, I address two outstanding questions regarding how linguistic and extra-linguistic information are brought together in the interpretation of language situated within a discourse. The first part of this dissertation experimentally addresses how alternatives invoked by sentences containing the focus-sensitive operator 'only' are…

Purpose: Cognitive Linguistics has repeatedly pointed out the major significance of metaphors. In particular, metaphors are highly effective in the context of political and economic discourse. We analyze the as yet ignored use of metaphors in standard economic textbooks as exemplified by Paul A. Samuelson and N. Gregory Mankiw. The following will…

We use thematic analysis to explore how mathematical concepts are developed in four enactments of the same task. Thematic analysis emerges from Systemic Functional Linguistics and provides a means to explore the development of mathematical ideas in the classroom discourse. Thematic analysis was used to explore how themes related to the comparison…

The paper begins by arguing that knowledge-blindness in educational research represents a serious obstacle to understanding knowledge-building. It then offers sociological concepts from Legitimation Code Theory--"semantic gravity" and "semantic density"--that systematically conceptualize one set of organizing principles underlying knowledge…

"Network" is a fashionable and current term in every field of contemporary society and education is no exception. In this paper, the concept of network (and other associated concepts, such as partnership and collaboration) is reviewed. Such revision regards selected theoretical contributions and is explored in terms of the use of the…

Based on sociocultural theory, this article examines two activities constituted by a parent and child as jointly constructed bi-literacy practices. Bi-literacy practices enable the parent and child to co-construct conceptual meanings and sense across two languages. Concept development in young children "begins" with meaning in one language and…

Maximizing the interaction between pupils with and without special needs is generally considered an important aspect of inclusion. However, it is frequently questioned whether pupils with special educational needs (SEN) in regular classrooms have interactions and friendships with their peers. In order to be able to evaluate these relationships, it…

This article presents a case study of academic language instruction in a high school "English Learner Science" course. It illustrates how a teacher's understanding of academic language affects her instruction and students' opportunities for learning. We examine a transcript of classroom discourse for the "didactic tension" that exists between this…

Discusses the notions of "word,""term," and "expression," and various semantic relationships with which the technical translator must deal. (AM)

Contrasts lay and "professional" metalinguistic knowledge from the viewpoint that linguistic issues concern all speakers of language. The article maintains that linguists firmly believe in a major difference between lay and theoretical metadiscursive remarks because linguists persist in believing in the objectivity of linguistic facts.…

It is suggested that twin discourse functions are served by thematization and topicalization, the former providing stable referential focus and the latter providing momentary referential focus. (Author/AM)

Presents accounts of theories locating the sources of the signifying capacities of words in their imbrication with nondiscursive structures and practices. Points out that a tradition of philosophical, linguistic, and semiotic theorizing has attempted to clarify what it is for words to have the meanings they do in terms of the relation of…

Every sentence conveys a temporal point of view through its aspectual meaning. This viewpoint arises through presenting a situation from a certain temporal perspective and indirectly classifying the situation as an exemplar of an idealized situation type. The information is conveyed by the aspectual categories of a language. This paper presents a…

Comparison of language-impaired two- to three-year-olds (N=10) and normal one-year-olds (N=15) matched for expressive language revealed that the language-impaired subjects acquired a greater number of object concepts presented in a no-action condition than the normal children, although language-impaired subjects' extensions of the names to new…

The procedures used to develop a list of concepts taught in fourth-grade language arts are described. Thirty concepts from the list were randomly sampled and then analyzed. Analysis consisted of listing examples and non-examples, relevant and irrelevant attributes, subordinates and supraordinates, and a definition and principle for each concept.…
