Susan D. Blum is one of a growing number of educators questioning the role of grades in learning. She's a professor and the editor of "Ungrading: Why Rating Students Undermines Learning (and What to Do Instead)." She advocates for a sweeping pedagogical shift based on the practice of 'ungrading' - not assigning a number or letter value to a student's work.
