The importance of models and modeling in science education is well-recognized, yet there exists significant polysemy among these terms within the literature. This ambiguity often leads to confusion, particularly regarding whether modeling represents an expected student performance, an instructional strategy to promote such performance, or both.…

Science should provide students an accurate and contemporary education on genetic influence, particularly how it impacts trait variability and developmental norms. Stories involving familial, racial, and sexual differences routinely appear in the popular media and sales of over-the-counter genetic tests are mounting. Unfortunately, research…

As more and more science teacher educators are subscribing to a practice-based teacher education curriculum, it is becoming increasingly necessary to identify and articulate smaller grain-sized teaching practices nested within a core practice in important instructional contexts in order to facilitate preservice science teachers' (PSTs') learning…

Supporting changes in undergraduate science, technology, engineering, and mathematics (STEM) instruction requires an understanding of the relationship between STEM instructors' conceptions and practices. In this study, the authors used the Teacher-Centered Systematic Reform (TCSR) model as a framework to understand how instructors' conceptions are…

This article presents a simple, cognitive theory of science and learning. The first section of the paper develops the theory's two main propositions: (i) A wide range of scientific activities rely heavily on one type of reasoning, hypothetical thinking, and (ii) This type of reasoning is also useful to students for learning science content. The…

As professional science becomes increasingly computational, researchers and educators are advocating for the integration of computational thinking (CT) into science education. Researchers and policymakers have argued that CT learning opportunities should begin in elementary school and span across the K-12 grades. While researchers and policymakers…

This study sought to better understand how past science learning experiences affected preservice elementary teachers, both in terms of their own self-efficacy and their perceptions of science teaching and learning at the beginning of their science methods course. Following an explanatory sequential mixed methods design, this study first involved…

We investigated the intersectional nature of race/racism and gender/sexism in broad scale inequities in physics student learning using a critical quantitative intersectionality. To provide transparency and create a nuanced picture of learning, we problematized the measurement of equity by using two competing operationalizations of equity:…

Many conversations surrounding improvement of large-enrollment college science, technology, engineering & mathematics (STEM) courses focus primarily (or solely) on changing instructional practices. By reducing dynamic, complex learning environments to collections of teaching methods, we neglect other meaningful parts of a course ecosystem…

Science as an enterprise has been and continues to be exclusionary, perpetuating inequities among whose voice is heard as well as what/whose knowledge is recognized as valid. Women, people of color, and persons with disabilities are still vastly outnumbered in science and engineering by their White, male counterparts. These types of imbalances…

Worldwide, teachers are expected to engage their students in authentic practices, like scientific modeling. Research suggests that teachers experience challenges when integrating modeling in their classroom instruction, with one explanation that teachers themselves lack the necessary modeling competence. Currently, theoretical conceptualizations…

Professional knowledge is an important source of science teachers' actions in the classroom (e.g., personal professional content knowledge [pedagogical content knowledge, PCK] is the source of enacted PCK in the refined consensus model [RCM] for PCK). However, the evidence for this claim is ambiguous at best. This study applied a cross-lagged…

Persistence is a major issue facing students, particularly those who are both female and from underrepresented ethnic minorities (URM). A closer look at the variables affecting their commitment and capacity for continuing the pursuit of their goal allows us to better design support systems that bolster persistence. This study tests a structural…

Although the practice of giving examples is central to the effective teaching and learning of science, it has been the object of little educational research. The present study attends to this issue by systematically examining the exemplification practices of a university professor and his students' learning experiences during a biology lecture on…

Science writing, such as lab reports, allows students to form a meaningful understanding of scientific concepts. However, students often view scientific writing as unimportant and utilize surface level approaches when completing writing assignments. The current study implemented three experimental interventions (directly-communicated,…
