Perspective of a Chemist: A Framework to Promote Conceptual Understanding of Chemistry.
Claesgens, Jennifer; Scalise, Kathleen; Draney, Karen; Wilson, Mark; Stacy, Angelica
Living by Chemistry (LBC) is a high school curriculum project that proposes framing the big ideas of chemistry to provide developmental cohesion across the curriculum and promote conceptual understanding. The proposed framework, called perspectives of Chemists," is intended to allow measurement of individual conceptual change in chemistry over time, in order to inform on the patterns and characteristics of the conceptual "change space" in the domain. The framework is based on integrating conceptual change theory with National and California State Science Standards, expert opinion, interviews with teachers, surveys of topics in high school chemistry, textbooks, and classroom observations of students. The resulting frame was tested and further developed in 2 small pilot studies with high school students in which student task responses were analyzed for progressions of student understanding, calibrated with item response theory measurement models, and mapped to proposed conceptual models of chemistry. Results are being incorporated into curriculum design efforts in a design experiment model of informing theory and practice concurrently. A larger initial field study at the secondary level is currently underway, with plans for further exploration of the framework at the university level. (Contains 2 figures and 27 references.) (SLD)
