Visions of Next Generation Science Standards-aligned instruction place high discursive demands on learners. Learners are expected to articulate, develop, and defend their ideas and respond to the ideas of others. Decades of prior research have carefully documented features, processes, and potential benefits and shortcomings of an emphasis on talk…

Informed civic engagement has long been a goal of science education. Yet, how youth civically engage using science--what knowledge and practices they draw on, when, how, and for what purposes--remains largely unknown. By examining youth civic digital media production around climate change and COVID-19, we shed light on this area. We view both…

To date, most studies of citizen science engagement focus on quantifiable measures related to the contribution of data or other output measures. Few studies have attempted to qualitatively characterize citizen science engagement across multiple projects and from the perspective of the participants. Building on pertinent literature and…

Science education researchers agree about the importance of evidence in science practices such as argumentation. Yet, disagreements and ambiguities about what counts as "evidence" in science classrooms pervade the literature. We argue that these ambiguities and disagreements can be viewed as falling along three fault lines: (i) the…

Mentoring relationships in academia have traditionally been described as a dyad between a mentor and a mentee. The mentor provides the mentee with both technical and psychosocial support to move toward obtaining their Ph.D. or gaining tenure and promotion. While there is an embedded assumption that mentoring is best suited when people of common…

Instructional shifts required by equitable, reform-based science instruction are challenging, especially in the elementary context. Such shifts require professional development (PD) that supports teacher internalization of new pedagogical strategies as well as changes in beliefs about how students learn. Because of this complexity, many PD…

This study explores ways to support girls of color in forming their senses of selves in science, technology, engineering, and math (STEM) during the middle school years. Guided by social practice theory, we analyzed a large data set of survey responses (n = 1,821) collected at five middle schools in low-income communities across four states in the…

It is well known that women are underrepresented in science. technology engineering and mathematics (STEM) and that their interest declines more steeply over the schooling years. As such, this study uses a STEM identity theoretical framework to examine the effects of early STEM experiences, focusing particularly on experiences that may be more…

Undergraduate students have different attitudes toward the geosciences, but few studies have investigated these attitudes using Q methodology. Q methodology allows the researcher to identify more detailed reasons for students' attitudes toward geology than Likert methodology. Thus this study used Q methodology to investigate the attitudes that 15…

In recent years, there have been programs aimed at increasing the number of science and math teachers in high-need areas by offering scholarships to candidates in exchange for their agreement to teach in a high-need school for a period of time. However, there has been concern that recipients might fulfill the terms of their agreement, then leave…

This paper focuses on interactions in a science professional development (PD) course in which participating teachers engaged in doing science. Whereas the PD design of this course aligned with research on effective PD practices, we found that these practices did not sufficiently account for the affective and relational dynamics that unfolded in…

This paper describes HASbot, an automated text scoring and real-time feedback system designed to support student revision of scientific arguments. Students submit open-ended text responses to explain how their data support claims and how the limitations of their data affect the uncertainty of their explanations. HASbot automatically scores these…

Through a randomized controlled trial, this mixed-methods study evaluated changes in elementary science teachers' understandings, confidence, and classroom implementation of problem-based learning (PBL), inquiry, and nature of science (NOS) instruction following participation in a professional development (PD) as well as the components of the PD…

School principals play a key role as instructional leaders in reform efforts, yet little is known about their knowledge of science. A key focus in recent reform efforts is the inclusion of science practices, which are potentially a significant challenge for schools. Consequently, we investigated K-8 principals' views of good science instruction…

Small group interactions and interactions with near-peer instructors such as learning assistants serve as fertile opportunities for student learning in undergraduate active learning classrooms. To understand what students take away from these interactions, we need to understand how and what they learn during the moment of their interaction. This…
