Background: To support collaborative drawing, it is essential to investigate how students make collaborative drawings and how these contribute to elaborating their ideas. This study examines how 5th and 6th grade students' group drawings contributed to increased levels of explanations of their drawings about sound transmission. Methods: We…

A central goal of science education reform is for students to participate in scientific sense making rather than to merely acquire science facts. However, even in classrooms utilizing reform-based pedagogies, students are typically allowed to construct knowledge only insofar as they construct expected knowledge. In this report and reflection, we…

Background: Recent alternative concepts of school knowledge emphasize knowledge creation via networks of learning around real-world phenomena. We studied entrepreneurship education as an example of new epistemic activity which opens institutional boundaries for active engagement with society in learning. Methods: We used a case-study strategy and…

This article explores 11- to 16-year-old students' explanations for phenomena commonly studied in school chemistry from an inclusive cognitive resources or knowledge-in-pieces perspective that considers that student utterances may reflect the activation of knowledge elements at a range of levels of explicitness. We report 5 themes in student…

Describes an approach to teaching complex models in science that uses a model construction cycle of generation, evaluation, and modification. Reports on a case study of a student in a tutoring experiment in the study of electric circuits. Focuses on the role of analogies, discrepant events, and the student's moments of surprise as motivators of…

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…

Explores how students' epistemological ideas about the nature of science interact with their conceptual understanding of a particular domain as reflected in written explanations for an event of natural selection constructed by groups of high school students through a technology-supported curriculum on evolution. Highlights the need for an…

Indicates the presence of complex structural, behavioral, and functional relations to understanding. Reports on a design experiment in which 6th grade children learned about the human respiratory system by designing artificial lungs and building partial working models. Makes suggestions for successful learning from design activities. (Contains 44…
