Leaf and Berry (2015) recruited 60 undergraduates from a beginning psychology course and randomly assigned half of them to learn course material from video games and the other half to learn course material from teaching course material to a peer. Students took a multiple-choice test to measure understanding of the course material. What type of design did Leaf and Berry use?
