In Building Thinking Classrooms, what students think about is as important as how they think. This workshop illustrates how Justice-Centered Ambitious Science Teaching (JuST) can serve as a powerful companion to BTC by anchoring learning in intellectually demanding, justice-centered phenomena that cultivates deep reasoning, collaboration, and equitable participation. Drawing from the work of Morales-Doyle (2017), Philip & Acevedo (2017), and Luehmann et al. (2024) we frame justice-centered science instruction as a means of expanding whose knowledge counts, whose experiences matter, and whose questions shape the investigation. These scholars emphasize that equitable science learning must position students, especially those historically marginalized in STEM, as sensemakers navigating problems in their communities. This workshop will demonstrate how such justice-centered phenomena fuel the cognitive demand central to BTC and create inclusive spaces for students’ ideas to drive instruction. We will share the journey of our high school science department that partnered with university faculty, administrators, and community organizations to transform instruction by incorporating local, justice-centered data into inquiry-driven lessons over the past 5 years. Our work honors key BTC principles, such as visibly random groups, thinking tasks, and teacher moves that support student autonomy. We use iterative modeling, where students generate, revise, and revisit scientific models over time. These models allow students to externalize their thinking, track changes in understanding, and engage in public reasoning while still maintaining flexibility and intellectual risk-taking.Participants will engage in a justice-centered science task: interpret local data, construct initial models, revise thinking collaboratively, and examine authentic classroom artifacts. Through this, they will experience firsthand how justice-centered phenomena create the need for disciplinary knowledge and how BTC structures amplify student voice and participation within that work.This workshop highlights how instructional practices and partnership systems intersect to create an approach to building more equitable, intellectually challenging science classrooms. Participants will leave with concrete tools to adapt JuST and BTC principles to their own context.Participants will leave this session with a clear understanding of the following:How integrating justice-centered phenomena serves as a powerful catalyst for creating intellectually challenging tasks that demand thinking from every student.How thoughtfully adapted BTC structures can support justice-centered ambitious teaching in science and other disciplines.Practical strategies for cultivating meaningful, multi-level collaborations (educator, administrator, university, community) to build the systemic capacity for sustained, equity-focused instructional improvement.
