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…

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…

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…

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…

The purpose of this study was to explore translanguaging space as a transformative third space, where alternative and competing discourses are celebrated and where science learning and the development of science's discourse and epistemic practices expand across overlapping boundaries (e.g., home, school, and community). The study focused on Syrian…

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…

Discussion forums are important components of online courses because of the collaboration and community they foster, and the language used within the discussion forums may be influential in this development. In particular, studying the gendered language patterns of discussion forums can help gain insight into students' state of mind and propensity…

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…

Research Findings: Conversing abstract concepts boost children's language learning. Despite the numerous studies on the linguistic environment of early childhood education settings (ECE), most of this work disregards contextual factors that may influence abstract conversations and omits characteristics of children's verbal participation in these…

Instructor Talk--the noncontent language used by an instructor during class time--is likely to influence learning environments in science classrooms from the student perspective. Despite Instructor Talk being found in every science course thus far, investigations into student perceptions and memories of it are limited. We investigated to what…

Whole-body sense-making offers insights for the analysis of identity work in learning in multilingual classroom contexts. The concept has the potential to draw together two strands of classroom discourse scholarship, namely multilingual and multimodal discourse studies. The data presented in this paper constitutes a moment of whole-body…

This research explored the practices of one science teacher, expert in her field, as she worked to enact science discourse that incorporated language in naturalistic and rigorous ways. Difficulties in mastering the language of science contribute to troubling and persistent achievement gaps across demographic and gender groups. Science learning is…

Communities develop social languages in which utterances take on culturally specific situated meanings. As physics students interact in their classroom, they can learn the broader physics community's social language by co-constructing meanings with their instructors. We provide an exposition of a systematic and productive use of idiosyncratic,…

Helping preservice teachers use hybrid language representations in science is important if they are to become scientifically literate and able to engage in the discourse for understanding scientifiyc issues. Using hybrid language representations based on the framework of computer-supported collaborative learning, the teacher educator applied the…

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…
