Recent educational reforms conceptualize science classrooms as spaces where students engage in Science-as-Practice to develop deep understandings of scientific phenomena. When students engage in Science-as-Practice they are constructing explanations, arguing from evidence, and evaluating and communicating information to develop scientific knowledge (NGSS Lead States, 2013). This process of learning requires a focus on productive science talk in which students grapple with and socially negotiate their ideas (Kelly, 2014) through interactions involving talk, joint attention, and shared activity aimed at building, negotiating, and refining new understandings of phenomena and relevant science concepts (Ford, 2015; Michaels & O’Connor, 2012). Productive talk requires the ‘nimble’ involvement of the teacher to help students productively contribute their ideas to the class and use them as resources to drive instructional activities supporting the development and refinement of more sophisticated scientific understandings (Christodoulou & Osborne, 2014; González‐Howard & McNeill, 2020).

How New Ideas Diffuse in Science
What conditions enable novel intellectual contributions to diffuse and become integrated into later scientific work? Prior work tends to focus on whole cultural products, such as patents and articles, and emphasizes external social factors as important. This article focuses on concepts as reflections of ideas, and we identify the combined influence that social factors and internal intellectual structures have on ideational diffusion. To develop this perspective, we use computational techniques to identify nearly 60,000 new ideas introduced over two decades (1993 to 2016) in the Web of Science and follow their diffusion across 38 million later publications. We find new ideas diffuse more widely when they socially and intellectually resonate. New ideas become core concepts of science when they reach expansive networks of unrelated authors, achieve consistent intellectual usage, are associated with other prominent ideas, and fit with extant research traditions. These ecological conditions play an increasingly decisive role later in an idea’s career, after their relations with the environment are established. This work advances the systematic study of scientific ideas by moving beyond products to focus on the content of ideas themselves and applies a relational perspective that takes seriously the contingency of their success.

Science Education has transitioned to science proficiency-- students are to gain the ability to engage in sense making about the natural world (National Research Council [NRC, 2012])--learning to “figure things out” (Passmore, 2014). One emerging area of focus is the emotional work students participate in during science sense making. There is growing recognition that these emotions are not just unnecessary by-products of scientific work, but rather they are part-and-parcel of doing science, as these emotions are part of what “instigates and stabilizes disciplinary engagement” in scientific pursuits (Jaber & Hammer, 2016b, p. 189). The research question that guided this study is: What is the teacher's role in reframing moments of epistemic vexation, so students experience productive meta-affect in the science classroom? After reviewing video footage and student and teacher interviews, three themes emerged: (1) Without reframing from the teacher during moments of epistemic vexation, students disengage from sense-making, (2) Productive meta-affect is more likely to occur when students understand why the teacher allows for failure to connect ideas or understand scientific concepts, and (3) When the teacher does not reframe moments of epistemic vexation, students build solidarity and reach out to each other for emotional support in developing productive meta-affect.more » « less

Recently there have been calls to integrate engineering design experiences to support students’ scientific understanding. There is a need for instructional strategies in which learners are encouraged to identify and reflect on ways scientific principles can be applied to inform their designs and evaluate alternative designs. Studies show that the inclusion of contrasting cases can improve students’ conceptual understanding and reasoning. Yet, such tasks depend on how they are scaffolded. In this study, pre-service elementary teachers in a conceptual physics course analyzed contrasting solutions to a design problem. Two forms of scaffolds were embedded to facilitate case evaluation: 1) identify similarities and differences and 2) evaluate and produce an argument for a “good” design solution. We investigated the scientific ideas that the participants used as they contrasted multiple design solutions and the impact of the two approaches in students’ understanding of heat transfer. We found no significant differences in students’ conceptual understanding, but the argumentation condition had a significantly larger number of scientific ideas ‘cited’, ‘explained’ or ‘applied’ in their solutions,. The results suggest that contrasting designs with argumentation may be a promising intervention to facilitate students to use science concepts in engineering design. Future work is needed in order to investigate better scaffolds that can help students’ increase in conceptual learning.more » « less

Abstract Recent instructional reforms in science education aim to change the way students engage in learning in the discipline, as they describe that students are to engage with disciplinary core ideas, crosscutting concepts, and the practices of science to make sense of phenomena (NRC, 2012). For such sensemaking to become a reality, there is a need to understand the ways in which students' thinking can be maintained throughout the trajectory of science lessons. Past research in this area tends to foreground either the curriculum or teachers' practices. We propose a more comprehensive view of science instruction, one that requires attention to teachers' practice, the instructional task, and students' engagement. In this study, by examining the implementation of the same lesson across three different classrooms, our analysis of classroom videos and artifacts of students' work revealed how the interaction of teachers' practices, students' intellectual engagement, and a cognitively demanding task together support rigorous instruction. Our analyses shed light on their interaction that shapes opportunities for students' thinking and sensemaking throughout the trajectory of a science lesson. The findings provide implications for ways to promote rigorous opportunities for students' learning in science classrooms.more » « less
