DRK-12 Research and Products
Publication | Diagnostic classification models (DCMs) are restricted latent class models with a set of cross-class equality constraints and additional monotonicity constraints on their item parameters, both of which are needed to ensure the meaning of classes…
Publication | In this work, we extend variational auto encoders (VAE) to estimate item parameters and correlated latent abilities, and directly compare the ML2P-VAE method to more traditional parameter estimation methods, such as Monte Carlo expectation-…
Publication | Professional development that privileges teachers’ voice, equity, and the investigation of high-quality instruction is essential to the mathematics education community. However, more research is needed to understand the process, content, and…
Publication | The work presented here focuses on student struggles in undergraduate general chemistry laboratory activities, the source of these struggles, and the actions students take to overcome them. Using an activity theoretical lens and multiple domains…
Publication | Chemical scientists and engineers are interested in controlling chemical processes to attain specific goals, from synthesizing a desired substance to hindering a particular transformation. Nevertheless, students typically have few opportunities…
Publication | Teaching chemistry as a practice rather than as a mere collection of facts demands that teachers modify their practices, particularly their approach to formative assessment (FA). In this study, we investigated how teachers’ FA practices changed…
Publication | The resources that multilingual students bring to school mathematics are often ignored. During a teacher-researcher collaborative project focused on creating more equitable learning environments in high school math classrooms, we noted an…
Publication | The University of Alaska Fairbanks (UAF) Development Team is working with the Northwest Arctic Borough School District to develop STEM lessons utilizing Iñupiaq knowledge systems and university research for middle school-age students in three…
Publication | Examining a lesson in a high school biology unit that utilized noisy sensor data, we sought to understand the ways students engaged in active reasoning about the data and the factors that influenced this process. Video analysis centers on one…
Publication | The global pandemic and climate change have led to unprecedented environmental, social, and economic challenges with interdisciplinary STEM foundations. Even as STEM learning has never been more important, very few pre-college programs prepare…
Publication | In this paper, we share the design and impact of a set of two-hour online mathematics professional development modules adapted from face-to-face video-based materials.
Publication | We investigate the algebraic discourse of secondary mathematics teachers with respect to the topic of equation solving by analyzing five teachers’ responses to open-ended items on a questionnaire that asks respondents to analyze hypothetical…
Publication | We explored how preservice teachers in a middle school science methods course learned and applied computational thinking (CT) concepts and activities during a month-long
intervention.
Publication | Teaching about wave structure and function is a critical element of any physical science curriculum and supported by Next Generation Science Standards (NGSS) PS4: Waves and Their Applications in Technologies for Information Transfer. Often,…
Presentation | NARST presentation on instructional decision making to improve argumentation in science.
Presentation | AERA presentation on elementary teachers’ perceptions and facilitation of argumentation in the context of professional learning.
Presentation | AERA symposium presentation on accessible distance learning in science during COVID.
Publication | This department explores the concept of disciplinary literacy—the conceptual understandings and ways of reading, thinking, and writing involved in critiquing and constructing knowledge in a discipline—and its intersections with aspects of…
Publication | We introduce and illustrate three principles for designing secondary mathematics classrooms in which multilingual students can benefit from participating in mathematical discussions. Drawing from the Academic Literacy in Mathematics (ALM)…
Publication | Emerging multilingual students can develop the dimensions of Academic Literacy in Mathematics (ALM) in classroom discussions. But, there is a need for empirically-validated principles for fostering such discussions. This research used ALM as a…
Publication | COVID-19 has thrust educators into a period of uncertainty, complicating conventional ways of teaching and learning. We suspect that the pandemic has magnified the challenges that some high school teachers already experience, particularly when…
Publication | Achieving data literacy is challenging when schools narrowly focus on statistical reasoning rather than on meaning- and inference-making. Without attention to the social contexts of data, learners can fail to develop a critical stance toward…
Publication | Interview with Steve Roderick about helping teachers on the InquirySpace project bring more authentic science experiences to their classes.
Publication | The process of using Learning Analytics (LA) to improve teaching works from the assumption that data should be readily shared between stakeholders in an educational organization. However, the design of LA tools often does not account for…
Publication | Despite the ease of accessing a wide range of measures, little attention is given to validity arguments when considering whether to use the measure for a new purpose or in a different context. Making a validity argument has historically focused…
