The purpose of the current study is to investigate the roles preferred by science teachers in the teaching of socioscientific issues (SSIs) in relation to the communicative approach and discourse patterns in the context of SSI and non-SSI. In this qualitative study, the holistic multiple case study design was used. The study group consisted of…

The importance of how classroom discourse can be used to support science learning has gained national attention with respect to both science teaching and research across K12 and higher education. In this review article, we examine a commonly referenced set of nine frameworks for use in "science" classrooms. Specifically, we examine the…

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,…

Purpose: The relationship between teacher talk and students' talk productivity is explored by two approaches: process-product, interpretive. Most studies used a process-product perspective by not considering the discursive compositions that may considerably modify the relations between a science teacher's talk interventions and students' talk…

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…

One of the challenges for analysing science classroom discourse is a better understanding of intercontextual relationships in the learning process. In this paper, we used orientations from ethnography in education to organise and propose an analytical metaphor called the hourglass approach. It involves three phases of analysis that correspond to…

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 provides rich insights into the process of data generation for discourse analysis from three separate studies of the video recordings of a single science classroom in action. The central claim is that multimodal transcription can contribute to developments in discourse theory. A three-stage reflective heuristic is developed and used…

To strengthen the professional development of its science university professors with academic assignments in scientific careers, a Colombian higher education institution commissioned the design of a six-month training programme. The aim was to help professors change their teaching practices toward more student-centred models. The purpose of this…

Instructor discourse, defined as verbal interactions with students in the classroom, can play an important role in student learning. Instructors who use dialogic discourse invite students to develop their own ideas, and both students and the instructor share ideas in back-and-forth exchanges. This type of discourse is well-suited to facilitate…

Background: Discourse is the teacher's principal pedagogical tool in class. Studies stress the importance of research on discourse in science education and demonstrate its cruciality for understanding science. Purpose: The purpose of this study was to investigate characteristics of the classroom discourse in lessons on physics. Sample: Classroom…

Classroom communication is increasingly accepted as multimodal, through the orchestrated use of different semiotic modes, resources, and systems. There is growing interest in examining the meaning-making potential of other modes (e.g., gestural, visual, kinesthetic) beyond the semiotic mode of language, in classroom communication and in student…

Teachers' responses to student contributions in science classroom influence the resulting classroom interaction. To establish a heightened interaction, teachers need to use specific discursive moves. Using the notion of noticing as a lens, in this qualitative case study, I report on how the notion of noticing and responding with a suitable…

This case study demonstrates teaching and learning activities in the school laboratory, and employs talk moves for the direct assessment of practical task effectiveness. By adopting a sociocultural linguistic approach (SCLA), learning chemistry is understood to be a discursive process in which knowledge is constructed through social interaction…

Science-learning research has addressed the analysis of discourse dynamics in classes oriented towards student-centred learning environments. One aspect not much investigated is the progressiveness of that discourse. For progressiveness to exist, interactions must tend to be symmetrical and power imbalances in dialogue must be reduced to a…
