The document describes two project-based learning projects implemented in an upper school Chinese classroom. The first project involved students researching the connections between lifestyle and health from Chinese and American perspectives through literature reviews, a field trip to Chinatown to interview locals, and interviews with peers. Students analyzed their findings to understand differences and similarities between the two cultures' views on maintaining health. The second project had students in different Chinese levels collaborate to create children's books, which they later presented to younger students. Both projects aimed to improve students' Chinese language skills through authentic hands-on activities.
