Our group were working with the teachers from two high schools, Chbar Ampov high school and Kratie Krong high school. Our first trip we went to Kratie Krong high school to train their teachers about the four topics. When we when there we were camping on the beach on Koh Truong and we have some fun at there. Also we want to follow up with the student from both schools so we went to their school again to see their students do their presentation and their final product of our PBL curriculum.
