Grades shape student's perception of their abilities & future prospects, yet outdated practices, proven inaccurate by decades of research, continue to distort students' self-identities and undermine their potential for success.  In this session, participants will critically examine the reliability & effectiveness of traditional grading through research-backed discussions, reflective activities, & case studies. Building on insights from Building Thinking Classrooms, participants will explore practical, data-driven grading strategies, hear inspiring stories from educators who have successfully transformed their practices, & gain resources and support for shifting toward grading practices that foster student growth & accurate self-reflection.
