Evolutionary theory is central to biology, and scientifically accurate evolution instruction is promoted within national and state standards documents. Previous literature has identified students' epistemological beliefs as potential predictors of evolution acceptance. The present work seeks to explore more directly how student views of evolution…

Carbon cycling is a key natural system that requires robust science literacy to understand how and why climate change is occurring. Studies show that students tend to compartmentalize carbon movement within plants and animals and are challenged to make sense of how carbon cycles on a global scale. Studies also show that students hold faulty models…

The goal of this study is to bring the voices of African American boys front and center in science education research in an effort to strengthen our understandings of their experiences of school and science. Using an interpretivist perspective within a narrative inquiry approach, I focus on the student and science-student identities two African…

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…

This study draws on data from a 10-month critical narrative inquiry of science teaching and learning in a third grade, dual language, integrated co-teaching classroom. The teachers were participants in a 14-week science professional development seminar that enrolled inservice and preservice teachers and focused on enhancing science teaching and…

Growing recognition of the central importance of fostering an in-depth understanding of natural selection has, surprisingly, failed to stimulate work on the development and rigorous evaluation of instruments that measure knowledge of it. We used three different methodological tools, the Conceptual Inventory of Natural Selection (CINS), a modified…

Students' views about science were correlated with their approaches to lab practice. Three distinct cases are discussed in detail: empiricist-oriented, rationalist-oriented, and constructivist-oriented students. A coherent epistemological theory was constructed for each case, by considering the different degrees of certainty and confidence each…

Investigated convergent validity of individual Piaget/Inhelder clinical task interviews with Reasoning Test (Ankney and Joyce), Logical Reasoning Test (Burney), and Classroom Test of Formal Operations (Lawson). Indicates that correlations obtained are not sufficiently strong to warrant selection/categorization of individual students based on their…

The impact of summer science-enrichment programs on high-school students' science motivation and confidence was evaluated in a 7-month period following program completion. The programs took place on a college campus. The splashdown effect was defined as program-related changes the program graduates recognized in themselves that became apparent to…
