Global carbon cycling describes the movement of carbon through atmosphere, biosphere, geosphere, and hydrosphere; it lies at the heart of climate change and sustainability. To understand the global carbon cycle, students will require "interdisciplinary knowledge." While standards documents in science education have long promoted…

This study examined age differences in young people's understanding of evolution theory in secondary school. A second aim of this study was to propose a new coding scheme that more accurately described students' conceptual understanding about evolutionary theory. We argue that coding schemes adopted in previous research may have overestimated…

While the majority of published research on conceptual change has focused on how misconceptions can be abandoned or modified, some recent research findings support the hypothesis that acquired scientific knowledge does not necessarily erase or alter initial non-scientific knowledge but rather coexists with it. In keeping with this…

Although taxonomic proficiency is a prerequisite for understanding ideas central to biology, previous research has established that learners frequently misclassify animals by not following the tenets of accepted taxonomic rubrics. This has immediate relevance with the recently revised English National Curriculum now requiring concepts of animal…

Because the school environment has been shown to play an important role in teacher and student performance, we undertook research into the assessment of school environment, differences between female and male science teachers' perceptions of their school environments, and associations between these school environment perceptions and teachers'…

To examine how school characteristics are tied to science and engineering views and aspirations of students who are underrepresented in science and engineering fields, this mixed-methods study explores relationships between aspects of students' science identities, and the representation of women among high school science teachers. Quantitative…

This study used judgmental and statistical procedures to evaluate the items in a statewide, 78-item, multiple-choice test of science knowledge. Differences in outcomes for these procedures are discussed. Authors conclude that both procedures should be used in test construction. (PR)
