A comprehensive, multi-layered deep dive into Culturally Responsive Teaching, this 3-Day summer intensive workshop will build on STEMteachersNYC CRT Task Force programming and create a space for participants to work together to co-generate a set of contextualized outcomes. The three day Dimensions of Responsiveness in STEM workshop will launch with a “Know Your Biases” unit, with a focus on uncovering and characterizing teacher individual biases. It then moves into a unit on grounding lessons in student perspectives, then on through unpacking content and pedagogical biases, and closes using a design thinking approach to resolving a problem of practice, embedding a strategy to address issues of equity, and/or to adapting a lesson or unit. The workshop will be open to both classroom STEM teachers as well as out-of-school time educators in an effort to address context specific challenges and to learn from each others’ experiences. By collaborating in this workshop, classroom and out-of-schooltime (OST) STEM educators will jointly build personal and shared reflection tools to foster Culturally Responsive and Sustaining Education practices in their lesson planning and execution. Participants will leave with a set of tools and strategies to revise lessons and units, and a catalogue of examples developed during the workshop by fellow participants.
