We present an empirically based model for modeling the quality of pre-service teacher reflection. Conversations from twelve groups of a total of 47 pre-service teachers were video recorded and transcribed verbatim. First, we analyzed their conversations through practical epistemology analysis and an operationalization of Dewey's definition of…

Multilingual youth, from nondominant communities, are often denied critical opportunities for engagement in robust sensemaking due to deficit-based perspectives and linguistic hierarchies. To advance equity, it is important to recognize all youth as epistemic agents and facilitate opportunities to take on intellectual positions. Drawing on…

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…

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…

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…

Background: Constructing knowledge through collaborative practical work is a complex process and involves the use of multiple modalities by group members. In practical work sessions, students often manipulate visual objects or textual materials but do not develop their scientific ideas. Purpose: This study illustrates (a) the challenges that…

Video is used widely to support teachers' learning and enactment of responsive instruction. Informed by principles of video club design, we designed a video club to support secondary science teachers developing a vision of responsive teaching, attention to student thinking, and a critical discourse to analyze their own and others' efforts to enact…

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…

Research on emotions illustrates a range of emotions that students and teachers experience, both individually and as a collective, in science learning settings. However, not as much attention has been given to how opportunities for emotional expressions are framed. Since emotions and their expressions are embedded in the discourse in which they…

Despite the importance of pedagogical content knowledge (PCK) in practical teaching and the inconsistency of teacher quality in different regions in China, there is little empirical evidence for specific differences in teachers' PCK in different districts in China. This study attempted to address this gap through analysis of practical teaching…

This study investigated science classroom discourse in terms of the types of teacher discursive moves (TDMs) and the relationships between the types of TDMs and student-led cognitive contributions in different science concepts by considering the classroom context. An experienced seventh-grade science teacher and her 19 students were engaged in…

This study identified the accumulated distributions of the enacted discursive moves during classroom inquiry to demonstrate how a science teacher reacted to the existence of two mutually exclusive social languages: everyday social languages of the students vs. social languages of school science. The participants were a science teacher and 26…

To promote rich discourse around scientific and engineering practices, teachers may turn to engineering design-based science curricula; however, this has discursive demands which have yet to be examined in a unit focused on integration of engineering and science. To investigate these discursive demands, we expand on the definition of discourse to…
