To free up classroom time for dialog, Sánchez-Gutiérrez created videos to teach vocabulary and grammar for home study. The videos use vividly designed scenarios and puppets to create engaging dialogs for travelers, such as “In the Taxi” and “At the Market.”

Wilson’s course is an upper-division elective in the economics major, which means large classes with students at a variety of preparation levels. The hybrid format lets students watch the lectures as many times as necessary. Videos incorporate the Learning Glass, a tool that allows her to illustrate her points on a board while facing the class -- improving the delivery mode of the traditional whiteboard/blackboard while preserving the lecture for future viewing.
