Abstract Grappling with uncertainty is an essential element of students' science learning and sense‐making processes, yet literature is limited regardinghowteachers can facilitate and use student scientific uncertainty as a pedagogical resource in their classrooms. Furthermore, progress on pedagogical practice depends on both the ability to notice one's perceptions and engage in opportunities to experience and reflect on new instructional approaches. To date, there are few professional development experiences explored in literature that explicitly aim to enhance teachers' awareness and pedagogical practice regarding the use and facilitation of student scientific uncertainty. As such, this qualitative study follows a group of 11 middle school science teachers before and after participating in a week‐long practice‐based professional development (P‐BPD) specifically designed to foster teachers' ability to use student uncertainty as a pedagogical resource. Interviews were conducted and analyzed prior to the P‐BPD, immediately after the P‐BPD, and the year following to measure shifts in perceptions over time. Additionally, classroom practice was observed both before and the year following the P‐BPD. Overall, we found that teachers' awareness of how to use student scientific uncertainty grew both in their expressed perceptions and in their observed classroom enactment. After engaging in the P‐BPD, many teachers expressed an enhanced awareness of the productive potential uncertainty can have, as well as increased understanding of potential sources and responses to student uncertainty. Additionally, in the post‐implementation observations, most of the teachers demonstrated more diverse use of uncertainty navigation strategies, intentionally raising, maintaining, and reducing scientific uncertainty more often. Teachers were observed using student ideas and uncertainties to drive the trajectory of their lessons more consistently. Notably, we report counterexamples for teachers who demonstrated less or no shifts in perceptions or practice. Furthermore, teachers explicitly identified experiences from the P‐BPD that fostered shifts in both their perceptions and practice. 

Science practice introduces inevitable uncertainties that are desirable for learning. Yet, navigating student scientific uncertainties can be a challenge for teachers. This qualitative study explored how teachers perceive and utilize uncertainty during science instruction. Analysis of interviews and classroom observations collected from 14 middle school teachers in the United States indicated limited awareness of uncertainty’s use as a resource in science. Teachers perceived uncertainty as a way to induce curiosity and persist through struggle; however, they were quick to reduce students’ scientific uncertainty throughout lessons. Findings suggest that teachers need support to understand how uncertainty navigation can benefit student learning. 

Abstract An essential aspect of scientific practice involves grappling with the generation of predictions, representations, interpretations, investigations, and communications related to scientific phenomena, all of which are inherently permeated with uncertainty. Transferring this practice from expert settings to the classroom is invaluable yet challenging. Teachers often perceive struggles as incidental, negative, and uncomfortable, assuming they stem from students' deficiencies in knowledge or understanding, which they feel compelled to promptly address to progress. While some empirical research has explored the role of scientific uncertainties in driving productive student struggle, few studies have explicitly examined or provided a framework to unpack scientific uncertainty as it manifests in the classroom, including the sources that lead to student struggle and how teachers can manage it effectively. In this position paper, we elucidate the importance of incorporating scientific uncertainties as pedagogical resources to foster student struggles through uncertainty from three perspectives: scientific literacy, student agency, and coherent trajectories of sensemaking. To develop a theoretical framework, we consider scientific uncertainty as a resource for productive struggle in the sensemaking process. We delve into two types (e.g., conceptual, epistemic), four sources (e.g., insufficiency, ambiguity, incoherence, conflict), and three desirability considerations (e.g., relevance, timing, complexity) of scientific uncertainties in student struggles to provide a theoretical foundation for understanding what students struggle with, why they struggle, and how scientific uncertainties can be effectively managed by teachers. With this framework, researchers and teachers can examine the (mis)alignments between uncertainty‐in‐design, uncertainty‐in‐practice, and uncertainty‐in‐reflection.
