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. 

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. 

Abstract Sensemaking has been advocated as a core practice of science education to support students in constructing their own understanding through a prolonged trajectory. However, the field lacks a discussion of teaching strategies that can better support students as they develop in the trajectory of sensemaking, which includes four phases: initial engagement with a driving question related to a target phenomenon; identification of incoherence and insufficiency in existing understanding; exploration of multiple resources to help develop plausible explanations; and synthesis of solutions and application of new understanding to interpret the target phenomenon. With the view that students' scientific uncertainty, including conceptual and epistemic uncertainties, can motivate or drive the trajectory of sensemaking coherent with students' understanding, this multiple case study examined how two science teachers, one from South Korea and one from the USA, supported students to navigate their scientific uncertainties to shape a trajectory of sensemaking that is coherent to them. Transcripts of video recordings of classroom discourses and student‐created artifacts were analyzed. We identified the dynamic nature of students' scientific uncertainties in the four phases and the teaching strategies in each phase. Three main findings emerged from this study: (1) student uncertainty as a key not only to initiate the trajectory of sensemaking meaningfully but also to continuously develop the trajectory along a coherent pathway, (2) conceptual and epistemic uncertainties having different roles in building different phases of sensemaking, and (3) teaching strategies that support student navigation of scientific uncertainty that drives the trajectory of sensemaking. 

Abstract This study aimed to develop a valid and reliable instrument, the Mental Images of Scientists Questionnaire (MISQ), and use the instrument to examine Chinese students’ mental images of scientists’ characters across school levels, regions, living settings, and gender. The final version of theMISQconsisted of four constructs: scientists’ cognitive, affective, lifestyle, and job characters. The results showed that senior high school students gave higher scores for scientists’ cognitive character construct than junior high and elementary school students did. Students from eastern regions, which have a more highly developed economy, gave the highest scores on cognitive and affective character constructs of scientists. Students from western regions, which have a less developed economy, had a relatively negative impression of scientists. Students’ images of scientists’ affective, lifestyle, and job characters were positively correlated with their interests in pursuing scientific careers. Future research to explore the relationships between students’ mental images of scientists’ characters and students’ motivation to pursue science-related careers or to engage in scientific practices are recommended. 

This study examines the relationship between epistemic curiosity (EC) and perceived uncertainty, which is posited to form an inverted U-shape, in the context of uncertainty-driven science learning (UDSL). Using path analysis, survey data from 181 middle school students collected at multiple timepoints across a three-week photosynthesis unit designed to facilitate UDSL were analyzed. Results show that the inverted U-shaped relationship between EC and uncertainty does not consistently hold over time. Instead, prior uncertainty negatively affects this relationship unless mediated by EC or sustained uncertainty in subsequent activities. At the trait level, the study highlights the mediating role of epistemic orientation toward uncertainty in fostering trait EC in UDSL. The findings underscore the importance of supporting students' productive uncertainty navigation and signify the positive impacts of UDSL in fostering EC. 

Students’ Dispositions toward Scientific Uncertainty Navigation (DSUN) can play a pivotal role in impacting student learning achievement. However, understanding of the underlying mechanism of DSUN influencing learning achievement is limited. Drawing from related research, this study investigates the roles of epistemic curiosity and learning engagement in mediating the relationship between DSUN and learning achievement. A survey study design was employed, involving 1,137 middle school students who participated in an uncertainty-driven learning environment when learning solar energy. A sequential mediation model was tested using data collected through validated measures assessing DSUN, epistemic curiosity, learning engagement, and learning achievement. Results revealed that while DSUN positively predicts learning achievement, this relationship is sequentially mediated by epistemic curiosity and learning engagement, with epistemic curiosity not serving as a significant mediator on its own. These findings underscore the importance of fostering both epistemic curiosity and engagement in science classroom activities when students encounter scientific uncertainty. 

In a traditional lecturing environment, students possess limited agency in accepting or rejecting information provided by teachers. A higher level of student agency involves opportunities and actively identifying uncertainties and collaborating with peers to deepen understanding within the classroom community. Teachers play a crucial role in guiding students through sensemaking by addressing uncertainties and assisting in solution development. Student uncertainty is recognized as a pedagogical resource, engaging them in sensemaking and enhancing agency levels. This study analyzed 28 whole-class discussions led by seven science teachers, identifying three phases: problematization, coherence negotiation, and new understanding enactment. The teachers employed eight strategies leveraging student scientific uncertainty as pedagogical resources within three sequential methods: eliciting awareness of uncertainty (e.g., creating hybrid, ambiguous, and problem-solving spaces), seeking a coherent understanding (e.g., connecting students’ lived experiences to empirical data for coherence, juxtaposing different interpretations to build consensus, and weaving together student ideas for coherence), and demonstrating new understanding (e.g., transference, translation). By embracing uncertainty, students become agents of sensemaking, contributing to a collaborative learning environment. 

This article presents an innovative instructional approach that assists teachers in designing and implementing their science unit: The SUPeR (Student Uncertainty as Pedagogical Resources) approach. The SUPeR approach suggests four phases of student learning in scientific practices and posits that student uncertainties drive the trajectory of learning. By applying the SUPeR approach, teachers can foster student curiosity and ensure a student-centered science learning environment. A sixth-grade solar energy unit is described to show how a science unit can be designed and implemented using the SUPeR approach. The article elaborates on teacher guidance for applying the SUPeR approach, how student uncertainty is used to foster student curiosity and drive the learning trajectory, how student learning can be assessed from the SUPeR perspective, and how the SUPeR science unit aligns with the Next Generation Science Standards. 

Productive struggle is a process in which students expend effort to grapple with perplexing problems and make sense of something that is not immediately apparent and beyond their current level of understanding and capacity. The experience encourages students to reflect on and restructure their existing knowledge toward a new understanding of scientific concepts and practice. Scientific uncertainty is common in scientific sensemaking practice and is one of the major factors provoking student struggle. A teaching approach called Student Uncertainty as a Pedagogical Resource (SUPeR) is introduced to encourage teachers to engage students in the practice of productive struggle. The SUPeR approach is composed of four phases: (1) problematize a phenomenon, (2) engage in material practice, (3) participate in argumentative practice, and (4) engage in reflection, transformation, and application. An example from an eighth-grade biology class unit on Mendel’s Law of Segregation is used to demonstrate how the SUPeR approach can be implemented in the classroom.
