"Do you understand your community environment?", "What is the community we live in like?" Through the process and results of reading, investigating, studying, recording, and discussing, we can better understand the characteristics of the community and also Can serve as the basis for action on community issues. Our course uses "theme mapping" as the purpose of drawing community maps. "Theme mapping" extracts information related to specific themes to create community ecological maps, land publicity, belief and culture maps. Through this activity, we allow students to understand the community and then use photos and words to present the beautiful people, things and things in this land. Furthermore, this is also the starting point for students to discover the problems around life, so that students can learn more about them in further courses. Understand the problems and then solve the current problems in the community.
