Effective feedback is a critical factor in student learning. However, time and resource constraints create a gap between the literature on feedback and the reality faced by instructors of large classes. Specifically, increasing class sizes impede instructors’ ability to provide thorough, frequent, and timely feedback to each student, especially in qualitative courses; this results in either reduced pedagogical quality or exhausted and discouraged instructors. With a focus on assessment as/of/for learning, this interactive session will examine the challenge of providing effective feedback to students in a manageable and sustainable way when scaling to large classes. Examples of effective assessment strategies will be presented, and participants will be invited to share their own feedback-related insights and experiences.
