Project Summary/Abstract Boston University School of Medicine’s new SEPA project, entitled "Mystery of the Crooked Cell 2.0: CityLab’s Next Generation Socioscientific Approach to Gene Editing," addresses the imperative that NIH's pre-college activities focus on biomedical workforce preparedness, especially for underrepresented minorities (URM). This project will reach close to 600 local URM students and, through planned dissemination, will reach thousands of students. CityLab is partnering with five Boston-area high schools and two afterschool STEM/health professions enrichment programs to test the effectiveness of embedding a focus on socioscientific reasoning (SSR) to promote understanding of gene editing. An SSR approach places science content in a meaningful social context and motivates students to take ownership of their learning. SSR skills include realizing the complexity of the content and context of an issue, analyzing an issue from multiple perspectives, seeking out sources of bias in data, and considering how and whether scientific investigations can advance understanding of an issue. This project will expand CityLab’s “Mystery of the Crooked Cell” hands-on, inquiry-based curriculum supplement that focuses on the molecular basis of sickle cell disease (SCD) by incorporating state-of-the-art gene editing content that is suffused with SSR. The new curriculum supplement, Mystery of the Crooked Cell 2.0 (MCC 2.0), will seamlessly integrate three elements: CityLab’s curriculum storyline and laboratory experiences, computer simulations of molecular biology assays developed at University of Wisconsin-River Falls, and immersive virtual reality simulations of gene editing for SCD therapies developed at UC Berkeley Innovative Genomics Institute. SSR will be embedded throughout MCC 2.0, as will awareness of STEM/biomedical science careers. CityLab will also build NextGen Scholars, a learning community that will not only engage students in advanced science content and lab applications using SSR but also foster attitudes that support equity and diversity in STEM. This project will demonstrate the feasibility and replicability of this pedagogical strategy; CityLab will then disseminate the curriculum widely and thereby sow the seeds for a diverse and inclusive future STEM workforce. The major objectives of the proposed project are: (1) to create MCC 2.0 in collaboration with high school teachers and students, (2) to build a diverse community of learners who use SSR to explore advanced science topics while gaining insights into the importance of diversity, equity, inclusion, and social justice in science, health, and society, (3) to examine changes in students’ science content understanding, SSR skills, science learner identity, and attitudes towards diversity in the biomedical sciences and medicine, (4) to track student participants through college to understand the broader impact of this approach, and (5) to earn designation as one of the first “Hi...
