This study explores the nature of classroom talk as a way of teaching physics implemented by newly trained teachers. Their training introduced them, among others, to sociocultural theory and the promotion of classroom talk as a deliberate teaching strategy. This study is framed by Mortimer and Scott's framework for productive classroom talk. Data…

This study aimed to explore Ethiopian middle school physics teachers' content knowledge (CK) and their implementation of Dialogic teaching (DT). A qualitative method, case study design, and purposive and convenient sampling employed in the study. Data collected using Classroom observation and Questionnaire from nine physics teachers. The…

While circuitry lessons have traditionally been first introduced in late elementary school, they remain challenging conceptually for undergraduates in physics and engineering courses. Seeking to provide a higher quality and earlier introduction to circuitry learning for young children (ages 3-5), this paper investigates the affordances of…

Computational thinking (CT) and modeling are authentic practices that scientists and engineers use frequently in their daily work. Advances in computing technologies have further emphasized the centrality of modeling in science by making computationally enabled model use and construction more accessible to scientists. As such, it is important for…

Recent research has argued that inquiry-based science learning should be guided by providing the learners with support. The research on guidance for inquiry-based learning has concentrated on how providing guidance affects learning through inquiry. How guidance for inquiry-based learning could promote learning about inquiry (e.g. epistemic…

We conducted a semester-long ethnographic study of group work in a physics class that implemented the investigative science learning environment approach. Students' conversations were videotaped while they were engaged in group learning activities. Our primary research goal was to better understand what factors made some groups more effective than…

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…

Despite the importance of scientific argumentation, it rarely occurs in science classrooms. Researchers have designed argumentation interventions to bridge this gap, but those efforts have limited impacts on transforming existing classroom practices. Argumentation is a linguistically social interaction. It is necessary to go beyond understanding…

Student-generated drawing is a useful strategy to construct students' scientific ideas. For exploring ways to support student-generated drawing, we focused on the perspective of 'Norms' -- shared behaviour patterns desirable in a community. We investigated what norms were formed and how they emerged when students made drawings to explain…

Students in inquiry science classrooms face an essential tension between sharing new ideas and critically evaluating those ideas. This tension poses affective risks that can discourage further discussion, such as the embarrassment of having an idea rejected. In this article, we analyze the discourse of three groups of undergraduate physics…

Due to benefits for teaching and learning, an increasing number of studies have focused on classroom dialogue and how to make it productive. Coding, in which the transcribed conversation is allocated to a set of features, is commonly employed to deal with the textual data arising from this dialogue. This is generally done manually and cannot…

Background: Physics is often seen as a discipline with difficult content, and one that is difficult to identify with. Socialisation processes at the upper secondary school level are of particular interest as these may be linked to the subsequent low and uneven participation in university physics. Focusing on how norms are construed in physics…

There is a long history of philosophical inquiry into the concept of explanation in science, and this work has some implications for the ways in which science teachers, particularly in the physical sciences (physics and chemistry), explain ideas to students. Recent work has outlined a constructivist approach to developing, delivering, and refining…

This review presents theoretical underpinnings supporting microethnographic-discourse analytic (ME/DA) approaches to studying educational phenomena. The review is presented in two parts. Part 1 provides an analytic review of two seminal reviews of literature that frame theoretical and methodological developments of microethnography and functions…

The aim of this study is to better understand how teachers use various embodied semiotic modes -- speech, gestures, gaze, and proxemics -- when they present scientific content to the entire class. To analyse the multimodal practices of these teachers, we integrated the social semiotic theory of multimodality and the joint action theory in…
