Our Vision
We, the conference committee, are committed to fostering an inclusive, equitable, and socially just learning environment by broadening access to mathematics for ALL learners. Historically and presently, students and communities have been left out, left behind, or erased from math learning and teaching. We are striving to address these inequities through the cultivation of positive mathematical mindsets, a shift to student-centered teaching practices, and the promotion of deep content understanding, with a goal to empower individuals and communities in their mathematical journeys.
We invite you to join us in enacting this vision at this year’s BTC Conference.
