Abstract

The Cognitive Apprenticeship for Engineers in Chemistry Laboratory (ChANgE Chem Lab) curriculum model is our response to the workforce challenge of retaining freshman engineering majors taking general chemistry. Our model is grounded in the theoretical framework of cognitive apprenticeship and involves engineering design and learning chemistry in context through collaborative work. The model is embodied in three-week problem-based activities that require students to use chemistry laboratory concepts in engineering Design Challenges (DCs). Thus, learning chemistry while making engineering practice explicit. The design of each DC is based upon our adaptation of model-eliciting activities (MEA), a framework from the modeling perspective in engineering education. Adherence to the MEA principles allow us to create open-ended and authentic modeling activities that support our goal. In this presentation, we detail the development process for the DCs as design-based research, illustrating how our redesign efforts are based upon incorporation of students’ perspectives from usability testing from across one semester of a general chemistry laboratory course.
