Each ManyClasses project investigates a specific educational intervention across a diverse set of real classrooms.

The following is a list of completed and planned ManyClasses projects. If you have run a ManyClasses-style project that you would like included in this list, please contact us.

ManyClasses 1: Timing of Feedback

When should students be given feedback after completing a course assignment? ManyClasses 1 is comparing the effect of immediate versus delayed feedback on course-relevant learning outcomes.

ManyClasses 2: Prequestions

Prequestions are ungraded questions that appear prior to a learning activity. Though learners rarely know the answers to these questions, presenting prequestions before a lecture, reading, or online video has been observed to improve learning from the subsequent activity when compared to activities not preceded by prequestions, even when students receive no feedback on their responses. ManyClasses2 examines the generalizability of this effect across classes and students.
