In this session, participants will explore an active learning strategy known as the Science Writing Heuristic. Features of SWH including beginning questions, procedures and results, and claims and evidence will be demonstrated through a lab simulation experience. After attending this session, participants will be able to: (1) articulate the components of an SWH laboratory experiment, (2) describe methods for soliciting and facilitating the generation of beginning questions, (3) show students how to derive evidence-based claims that are drawn from the actual data collected in lab, (4) articulate the structure of the SWH laboratory experience and contrast it with the laboratory report format.
