Quizzes are prepared by the professor based on information from the current reading assignment. The quizzes are distributed to the students, who answer the questions and return the completed quizzes to the professor. The professor's teaching assistant (TA) collects the quizzes from the professor and grades them. The TA records the grades in a database and returns the graded quizzes to the professor. The professor reviews the graded quizzes and saves copies of a selected sample for use in accreditation reviews. The professor returns the graded quizzes to the students. At the end of the semester the professor uses the quiz grades to calculate course grades, which are posted to the COIN system.
