Conventional: 30 students in a class are taught the subject matter by a teacher; students are given periodic tests. Mastery Learning: Same as Conventional, but with additional formative assessments and feedback to determine the extent to which students have mastered the topic. Tutoring: Groups of 13 students are taught by a tutor over the 3week period and given the same assessments as the Mastery Learning group.
