Discourse

Student participation in science discourse requires multiple levels of support through tools such as curricular materials, as well as teacher talk. The actions of the teacher can provide opportunities for students to engage in disciplinary science talk. The norms associated with this talk can be used to define what students sound like when engaged in authentic science talk. However, often talk moves are employed in service of in-the-moment tasks rather than development of disciplinary talk norms.

This article presents results from a design experiment intended to develop students’ understanding of linear functions and rates of change in a linguistically diverse ninth grade classroom. The intervention focused on fostering classroom discussions. Students’ pre-post assessment gains were higher in the redesigned classrooms than in the pre-intervention classrooms. Additionally, multilingual students who were classified as English Learners (ELs) made larger gains than their non-EL peers, and the majority of student learning gains occurred on conceptually-focused items.

Teaching science to elementary school students is complex, and teacher preparation programs must support preservice teachers’ learning to communicate science content and practices with children. Science teachers bring the experiences they have as students to their teacher preparation, and these experiences may support or conflict with what they are learning about effective teaching. In this study, we present stories of two first-year teachers who attended a STEM-focused teacher preparation program in the U.S.

We consider how intentionally planned and facilitated whole-class conversations can “make space” for students’ sense-making about engineering problems and solutions and position them with epistemic authority to contribute to collective thinking. We conducted a case study on a first-grade engineering lesson that included whole-class Idea Generation and Design Synthesis Talks. We found students sense-making as they refined their design proposals and analyses in light of classmates’ contributions to the whole-class conversations.

Teacher-facilitated whole-class conversations can help elementary students apply the full power of the NGSS science and engineering practices to an engineering design process. In this article we describe and provide examples for five kinds of Design Talks. Each type of Design Talk centers on a different framing question and is facilitated by specific prompts that help students voice their ideas and make connections to others' ideas.

This study investigated how preservice elementary teachers' (PSTs) noticed the discourse practices they used to position students and their scientific thinking as they engaged a group of student avatars in argumentation-based simulated discussions. Using qualitative methods, 82 teaching reflections from 28 PSTs were analyzed. Findings indicate that in most reflections (66%), the PSTs were able to support co-construction of knowledge in the Mursion® simulations.

Eliciting and interpreting students’ ideas are essential skills in teaching, yet pre-service teachers (PSTs) rarely have adequate opportunities to develop these skills. In this study, we examine PSTs’ patterns of discourse and perceived learning through engaging in an interactive digital simulation called Eliciting Learner Knowledge (ELK). ELK is a seven-minute, chat-based virtual role play between a PST playing a “teacher” and a PST playing a “student” where the goal is for the teacher to find out what the student knows about a topic.

Facilitating discussions is a key approach that science teachers use to engage students in scientific argumentation. However, learning how to facilitate argumentation-focused discussions is an ambitious teaching practice that can be difficult to learn how to do well, especially for preservice teachers (PSTs) who typically have limited opportunities to tryout and refine this teaching practice.
