DRK-12 Research and Products
Publication | The give-n task is widely used in developmental psychology to indicate young children’s knowledge or use of the cardinality principle (CP): the last number word used in the counting process indicates the total number of items in a collection.…
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 | 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 | 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 | 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 | 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 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 | TU professor studies avatar-based classroom simulations in three-year, $3 million NSF grant.
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 | 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 | 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 | 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 | 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 | 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 | 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 | 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 | In this paper, we present an overview of the design research used to develop a digital collaborative environment with an embedded problem-based curriculum. We then discuss the student and teacher features of the environment that promote inquiry-…
Presentation | The CADRE Learning Series was designed to provide targeted support for STEM education researchers on topics of DRK-12 needs and interests. The learning series has covered the topics of professional development and case study design.…
Publication | Ed+gineering, an NSF-funded program, adapted hands-on robotics instruction for online delivery in response to the COVID-19 pandemic. This qualitative multiple case study shares the experiences of participating education students in spring 2021…
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 | 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.
