This document discusses the use of flipped classrooms for teaching Spanish 101 vocabulary. It presents research on implementing flipped classes, where vocabulary is presented through online videos as homework, leaving class time for active practice and review. Surveys of students found that the majority felt reviewing vocabulary online before class helped them participate more in class and retain information better. The research concluded that flipped classes helped save time in class for practice and allowed students to review materials at their own pace outside of class.
