This research draws on Legitimation Code Theory (LCT) to understand the epistemic dimension of the higher education classroom discourse of a professor who is well evaluated by his students. In expository science classroom discourse, concepts are loaded with different meanings, a process that is called "condensation of meanings" in LCT,…

The purpose of this study was to examine the ways in which teachers use language to promote vocabulary development (i.e., vocabulary talk moves) during science instruction in early-elementary classrooms. Twenty-four total science lessons were recorded by eight teachers, providing 894.27 min of observational data across three timepoints. Discourse…

Debates on the philosophical interpretations of quantum physics have motivated a renewed interest in how secondary and lower undergraduate students interpret quantum phenomena. In an attempt to contribute to this effort, this paper examines the dynamics of perspective in quantum physics in the context of teacher education. The goal of the study is…

In content and language integrated learning (CLIL) classrooms, it is assumed that non-language content subjects provide more authentic communicative contexts for students to learn a foreign/second/additional language (L2). However, learning abstract concepts and academic language in an L2 simultaneously is also challenging for CLIL students. It is…

Language in chemistry is highly specialized, and for students, transitions in language complexity from high school to university can be extremely challenging. With an increasingly diverse cohort of students enrolled in UK chemistry degree programs, better understanding the linguistic challenges students face is becoming a greater pedagogical…

This methodological paper presents an approach for examining emotional expressions through discourse analysis and ethnographic methods. Drawing on trends in the current literature in science education, we briefly explain the importance of emotions in science education and examine the current research methodologies used in interactional emotion…

Latent Semantic Analysis (LSA) plays an important role in analyzing text data from education settings. LSA represents meaning of words and sets of words by vectors from a k-dimensional space generated from a selected corpus. While the impact of the value of k has been investigated by many researchers, the impact of the selection of documents and…

Just as language reflects one's thoughts, the text of science textbooks reflects the structure of scientific knowledge and thought. Therefore, students' learning of scientific language leads to their acquisition of the structure of scientific knowledge and thought. The purposes of this study were to extract scientific semantic network from science…

This paper comprises findings from three parallel case studies within the broad framework of English for Academic Purposes (EAP). These provide results from classroom-based action research conducted over two years working with Semantics, Specialisation and axiological cosmologies from Legitimation Code Theory (LCT). Each author shares how one or…

This interpretive case study is framed within recent sociocultural conceptualisations of learning. It draws on research on teacher-led classroom discussions, and investigates the conversational intricacies through which "dialogicity" is accomplished in adaptive ways in one content and language integrated learning (CLIL) science…

The purpose of this study was to find out how teachers use questions in classroom discourse to scaffold student thinking and help students construct scientific knowledge. The study was conducted in large-class settings where the medium of instruction was English although the students were non-native speakers of the language. Six teachers teaching…

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…

Scientific discourse is difficult to read because of its lexical, syntactic, semantic, and logical features. This paper discusses each of those features, giving special attention to syntax, and suggests ways in which discourse analysis can be used to teach content reading in sciences and to rewrite scientific text for instructional purposes. Some…
