The most obvious feature of expertise in chemistry is content knowledge, which defines the primary objectives of instruction. Research in chemistry education, and STEM education more broadly, has also devoted attention to students' developing scientific practices of reasoning, investigation, and learning. In this study, we set out to investigate…

Studies of learning in school settings indicate that many students frame activities in science classes as the production of answers for the teacher or test, rather than as making new sense of the natural world. A case study of an episode from a class taught by the first author demonstrates what productive and unproductive student framing can look…

Research on personal epistemologies (Hofer & Pintrich, 2002) has mostly conceptualized them as stable beliefs or stages of development. On these views, researchers characterize individual students' epistemologies with single, coherent descriptions. Evidence of variability in student epistemologies, however, suggests the need for more complex…

Explores connections between naive epistemology and everyday instructional practice. Reviews examples of naive epistemologies as made up of fine-grained, context-sensitive resources. Presents strategies designed to help students tap those resources for learning introductory physics. Reflects on this work as an example of interplay between two…
