Teaching in Vietnam recently, I had opportunities to work with some amazing students and teachers. Being in such a position lent itself well to cultural exchanges inside and outside the classroom. However, it was clear to me, to my colleagues, and I believe to the majority of students that there was a need to dig deeper--to move beyond the cultural dos and don'ts and the comparisons of cultural practices and behavior. As teachers, we must also support and motivate students to reflect on and investigate how one's own and others' cultural beliefs, attitudes, and norms are shaped. Additionally, being in an English as a foreign language (EFL) context requires English-language support and activities that motivate students to engage in English. This article presents four lessons based on project-based learning (PBL) that I used with EFL students in Vietnam and that other teachers can use with students in their own contexts. The lessons focus on developing students' English proficiency, research and analytical skills, and their ability to produce and present work collaboratively. Furthermore, these lessons aim to create not only a successful learning experience but also a more understanding and peaceful world.
