This multiple case study describes error-reaction patterns (ERPs) in middle school science lessons. Twenty-seven science teachers' reactions to student errors were explored in terms of four aspects of classroom discourse: talk move, discursive purpose, communicative approach, and patterns of interaction. Two hundred ninety-six error-reaction…

Questioning is a critical instructional strategy for teachers to support students' knowledge construction in inquiry-oriented science teaching. Existing literature has delineated the characteristics and functions of effective questioning strategies. However, attention has been primarily cast on the format of questioning like open-ended questions…

This study investigates if a force-based teaching approach, based on quantum mechanical principles and developed in a lesson study, would enhance the understanding of chemical bonding among upper secondary school students. The teaching approach was based on research on the teaching and learning of chemical bonding. The study included first-year…

The present paper analyzes and discusses specific methodological aspects instrumental in promoting the teaching of Green Chemistry (GC); it examines proposals and teaching experience reports from 284 papers published in the "Journal of Chemical Education" (JChemEd), until 2019. Using Discursive Textual Analysis and drawing upon previous…

A number of scholars have shown the prevalence of multiple metaphors in biological conceptions of the living cell. However, there is little research into unpacking these metaphors to understand their ideological implications for scientific knowledge and science education. In this paper, I perform a critical discourse analysis of the representation…

This study reports on eleven second-year teachers who were all students in the same practice-based secondary science methods courses framed around ambitious science teaching. In this qualitative embedded single case study, we examined if, how, and why novice teachers linked their current critical pedagogical discourses and instruction back to any…

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…

Background: Change strategies may leverage interpersonal relationships and conversations to spread teaching innovations among science faculty. Knowledge sharing refers to the process by which individuals transfer information and thereby spread innovative ideas within an organization. We use knowledge sharing as a lens for identifying factors that…

With the rise in implementation of peer-led learning in higher education, the interactions between peer instructors and their students warrant further investigation as an increasingly critical component of student learning. In this work, Teaching Interns (TIs) are undergraduate peer instructors that lead supplemental learning sessions in General…

Although visual aids are widely considered a valuable source of scaffolding, the nature and active utilization of these aids in current science classrooms are not well understood. This qualitative study explores interaction in the teaching of concepts related to evolution, with a specific focus on a teacher's use of different visual support…

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…

Three new physics teachers graduating from a university provider of initial teacher education in England were paired with a recently retired physics subject specialist teacher in order to provide informal mentoring during their first year of teaching. The aim of this was to explore if a mentoring intervention of this kind could support teacher…

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…
