In-class assessment processes are grounded in teaching best practices. Formative in-class assessment and frequent feedback about the quality of student learning helps instructors find out if learning is taking place, what students are learning, and how well they are learning. Through in-class assessment techniques, students can find out the same information. Post-assessment allows instructors to employ the information s/he has gathered in order to change teaching trajectories as well as to assist students in making their learning more efficient and more effective.
