Texts play an integral role in science research and science classrooms yet biology textbooks have traditionally failed to reflect the epistemic elements of the discipline such as justification of claims and visual representations of empirical data. This study investigates high school biology students' reading experiences when engaging more…

This paper focuses on the trade-offs that lie at the intersection of methodological requirements for causal effect studies and policies that affect how and to what extent schools engage in such studies. More specifically, current federal funding priorities encourage large-scale randomized studies of interventions in authentic settings. At the same…

In this case-study, we present a longitudinal study of one elementary (grades 1-6) school's environmental education (EE) in order to understand the ways in which the school culture supports outdoor EE as a critical component of their science education program. The school, which was known for its school-based EE curriculum that encompasses an…

The underrepresentation of non-White students and girls in STEM fields is an ongoing problem that is well documented. In K-12 science education, girls, and especially non-White girls, often do not identify with science regardless of test scores. In this study, we examine the narrated and embodied identities-in-practice of non-White, middle school…

The present study is based on the empathizing-systemizing (E-S) theory of cognitive science. It was hypothesized that the influence of students' gender on their motivation to learn science is often overestimated in the research literature and that cognitive style is more important for motivation than students' gender. By using structural…

Teacher-led whole class discussions are essential when it comes to guiding students' construction of knowledge, and recent studies on teaching and learning emphasize the need for more student-centered teaching methods. In previous studies, the extent to which different types of communication take place in the classroom have been extensively…

Positive student outcomes of undergraduate research experiences (UREs) have been well documented, however, many studies have neglected the logical relationship among outcomes, the processes through which they are achieved, and the contextual and participant factors at play in UREs. This study uses structural equation modeling to explore these…

Citizen science projects provide non-scientists with opportunities to take part in scientific research. While their contribution to scientific data collection has been well documented, there is limited research on how participation in citizen science projects may affect their scientific literacy. In this study, we investigated (1) how…

As colleges and universities aim for greater diversity in their undergraduate populations, one population researchers consider is first-generation students, or students whose parents do not have a college education. The research reported here addresses first-generation college students' discipline of study (e.g., biology) and its impact on…

This study introduces a new group of students to the postsecondary science agenda: "latecomers to science." Latecomers, who enter postsecondary science through alternative routes because they are missing prerequisites, are less likely to graduate than traditional science students. Challenges to latecomers' persistence are explored…

Achievement goal theory distinguishes between mastery goals (the goals of developing competence) and performance goals (the goals of demonstrating competence) [Ames [1992] "Journal of Educational Psychology" 84: 261-271]. In this study, we employed this theory aiming to better understand why adolescents' motivation to learn science…

Powerful online visualizations can make unobservable scientific phenomena visible and improve student understanding. Instead, they often confuse or mislead students. To clarify the impact of molecular visualizations for middle school students we explored three design variations implemented in a Web-based Inquiry Science Environment (WISE) unit on…

While research has shown that elementary (K-5) students are capable of engaging in the scientific practice of explanation construction, commonly-used elementary science curriculum materials may not always afford them opportunities to do so. As a result, elementary teachers must often adapt their science curriculum materials to better support…

Multiple illustrative case studies were used to investigate guided inquiry methods and the benefits of traditional science notebooks versus electronic science notebooks for students with moderate to severe intellectual disabilities. Results indicated students successfully acquired science content and increased motivation through science inquiry…

Grounded in sociocultural theory, this study explores how the figured world of science is reworked through a series of multi-media activities that were introduced into a girls-only conversation club in an after school program for Teens. The study is part of a multi-sited ethnography in which we explored youths' engagement with science within…
