“We need to step it up—We are basically the future”: Latinx young women co-construct science storylines in high school chemistry

Researchers and practitioners in the United States increasingly promote phenomena-based instruction in science that supports the development of a coherent storyline throughout the unit. Questions about who is constructing the science storyline and how still remain. Employing a qualitative ethnographic case study approach, we explore how three Latinx female students authentically contribute in their high school chemistry class and change the science storyline originally developed by the teacher. Data include over 950 min of video recordings, student artifacts, and interviews collected from a unit about reaction rate, which was contextualized by students' experiences with a local wildfire. The analysis points to three instructional moves that appear to play an important role in shifting the collective storyline: connecting to Latinx students' personal concerns, moving across multiple figured worlds, and recognizing students' epistemological contributions. Implications for supporting minoritized students are discussed.
