DRK-12 Research and Products
Publication | This study contributes to the growing body of research that highlights the usefulness of professional noticing of children’s mathematical thinking for understanding the complexity and variability in teaching expertise. We explored the noticing…
Publication | Examining teachers’ knowledge on a large scale involves addressing substantial measurement and logistical issues; thus, existing teacher knowledge assessments have mainly consisted of selected-response items because of their ease of scoring.…
Publication | This article presents a vision for 2025 to implement low cost and effective extended reality (XR) technologies to supplement teacher education field experiences, regardless of if and when another global or local crisis occurs (e.g., pandemic,…
Publication | TU professor studies avatar-based classroom simulations in three-year, $3 million NSF grant.
Publication | The Next Generation Science Standards (NGSS) have been imperative for informing many facets of the chemistry education research field, one of which includes the professional development (PD) of high school teachers. While many researchers and…
Publication | Concord Consortium’s new Earth Rocks Map displays a generalized representation of Earth’s geology, focused primarily on the distribution of the three major rock types (igneous, metamorphic, and sedimentary). What makes this map different is that…
Publication | In this chapter, we argue that the learning sciences and science education have coevolved, a co-evolution that began with the emergence of the learning sciences in the 1990s and that continues today.
Publication | This study investigated how newcomer emergent bilinguals made meaning in two 9th-grade biology classrooms. Methods relevant to naturalistic inquiry were used to collect and analyze data. Findings indicate that newcomers bridged aspects of…
Publication | Women and ethnic minoritized individuals are underrepresented in science, technology, engineering, and mathematics (STEM) domains in postsecondary education and in the workforce. The aim of the current study was to examine whether adolescents'…
Publication | Problem solving is a central focus of mathematics teaching and learning. If teachers are expected to support students' problem-solving development, then it reasons that teachers should also be able to solve problems aligned to grade level…
Publication | The InSTEP professional learning platform aims to support grades 6-12 teachers’ professional learning in teaching statistics and data science through a personalized online learning platform. While statistics and data analysis are included in…
Publication | The purpose of this study was to examine the effects of different data conditions on item parameter recovery and classification accuracy of three dichotomous mixture item response theory (IRT) models: the Mix1PL, Mix2PL, and Mix3PL.
Publication | Immersive 360 videos are increasingly being used in pre-service teachers (PST) education. There is preliminary evidence that this technology may benefit future educators’ focus and attention to classroom settings and events. However, more…
Publication | Researchers have typically identified and characterized teachers’ knowledge bases (e.g., pedagogical content knowledge and subject matter knowledge) in an effort to improve enacted instructional strategies. As shown by the Refined Consensus…
Publication | Professional noticing is an essential skill for teachers that is enacted by teachers via their embodied senses (sight, sound, etc.). To better understand the nature of teacher noticing, 44 preservice teachers (PSTs) viewed a 360 video of an…
Publication | While tragedy has struck an inordinate number of students in the past several years, not all areas of the country are at risk for every natural hazard all the time. To avoid having students feel like Chicken Little under a falling sky, the…
Publication | We describe an online citizen science platform for human brain and behavior research that uses a participatory science learning approach to engage learners in the full spectrum of scientific inquiry.
Publication | This position paper advocates supporting computer science (CS) teacher professional learning by supplementing existing curriculum-specific teacher professional development (PD) with standards-aligned PD that focuses on teachers' conceptual…
Publication | This article addresses the need and potential for students to develop problem-solving skills as part of STEM learning.
Publication | Teachers’ professional noticing has been described as transitioning from descriptions of general pedagogy to analysis of students’ mathematical procedures and conceptual reasoning. Such a shift is described as a transition towards more student-…
Publication | Bioinformatics—a rapidly developing discipline that integrates mathematical and computational techniques with biological knowledge for applications in medicine, the environment, and other important aspects of life—is an example of an emerging…
Publication | In super-diverse classroom contexts, students come from varied migration channels, immigration statuses, languages, countries of origin, and religions, which contribute to new and complex social configurations of the classroom. Super-diversity…
Publication | Implemented was a 45-minute per day Primary Science IDEAS intervention in grades 1–2 integrating reading and writing within science instruction in a multi-year study conducted in 8 experimental and 9 control schools. Results found a significant…
Publication | Posterior Predictive Model Checking (PPMC) is frequently used for model fit evaluation in Bayesian Confirmatory Factor Analysis (BCFA). In standard PPMC procedures, model misfit is quantified by comparing the location of an ML-based point…
Publication | The Innovate to Mitigate project adapts crowdsourcing to support project-based STEM education, posing design challenges for secondary-school students. Students are charged with designing feasible innovative strategies to mitigate CO2 emissions…
