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.

Unpacking the Complex Relationship Between Epistemic Curiosity and Uncertainty in Uncertainty-Driven Science Learning
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.

Sensemaking is conceptualized as a trajectory to develop better understanding and is advocated as one of the fundamental practices in science education. However, the field is lacking of a framework to view the prolonged process of sensemaking that starts from a raise of uncertainty of a target phenomenon to a grasping of a better understanding of a target phenomenon. The process requires teachers to recognize the role of scientific uncertainty in different phases of sensemaking and develop responsive instructional supports to help students navigate the uncertainties. With an attention on student scientific uncertainty as a potential driver of the trajectory of sensemaking, this study aims to identify different phases of sensemaking that can be developed with students’ scientific uncertainty. This study especially attends to two types of scientific uncertainty—conceptual and epistemic uncertainties. Conceptual uncertainty refers to student struggle of using conceptual understanding (e.g., mastery of content and everyday knowledge) to respond to an encountered phenomenon. Epistemic uncertainty emerges from struggles in using epistemic understanding to generate new ideas. Based on the multiple case study method, we examined sensemaking activities in two Korean science classrooms and one American science classroom and identified three phases of sensemaking: (a) focusing on a driving question related to a target phenomenon, (b) delving into multiple resources to develop plausible explanation(s), and (c) examining the successfulness of the new understanding and concretizing it. Based on the findings, we discuss two emerging themes. First, sensemaking progresses through three distinctive phases driven by students’ dynamically evolving scientific uncertainty. Second, attending to both epistemic and conceptual uncertainties can support developing sensemaking coherent with students’ view.more » « less

Estimating and disentangling epistemic uncertainty, uncertainty that is reducible with more training data, and aleatoric uncertainty, uncertainty that is inherent to the task at hand, is critically important when applying machine learning to highstakes applications such as medical imaging and weather forecasting. Conditional diffusion models’ breakthrough ability to accurately and efficiently sample from the posterior distribution of a dataset now makes uncertainty estimation conceptually straightforward: One need only train and sample from a large ensemble of diffusion models. Unfortunately, training such an ensemble becomes computationally intractable as the complexity of the model architecture grows. In this work we introduce a new approach to ensembling, hyper-diffusion models (HyperDM), which allows one to accurately estimate both epistemic and aleatoric uncertainty with a single model. Unlike existing single-model uncertainty methods like Monte-Carlo dropout and Bayesian neural networks, HyperDM offers prediction accuracy on par with, and in some cases superior to, multi-model ensembles. Furthermore, our proposed approach scales to modern network architectures such as Attention U-Net and yields more accurate uncertainty estimates compared to existing methods. We validate our method on two distinct real-world tasks: x-ray computed tomography reconstruction and weather temperature forecasting.

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.more » « less

Reform-based instruction that fosters all students’ intellectual engagement and sensemaking is possible. However, it is not yet prevalent across many science classrooms. To gain more insight into how to design and enact science instruction supporting students’ intellectual engagement, this investigation centered on understanding how to design and implement science lessons for promoting students’ intellectual engagement as epistemic agents who shape knowledge building happening in the classroom. We examined a middle school science teacher's design and implementation of four lessons that she did as part of a PD focused on fostering productive science talk in science classrooms. Our analysis revealed that her efforts in fostering opportunities for students’ epistemic agency were evident in both her lesson design and implementation. Her responsiveness to students’ thinking/intellectual engagement throughout the lesson implementations via principled improvisations supported opportunities for students’ epistemic agency. Her efforts allow us to understand how the design and implementation of science lessons with the focus of opening space and maintaining this space by being responsive to students’ thinking are critical for fostering students’ epistemic agency. These findings can provide implications for professional development efforts that seek to develop teachers’ capacity for reform-based instruction in science classrooms.more » « less
