Currently we are M2 students in the English program at Samakkhi Witthayakhom School in Chiang Rai, our research project is focusing the recycling behaviors of the English program students. When we were primary students, our campus environment was very clean and safe, whereas the environment here at Samakkhi is quite different. We are able to see trash piled up in different places as well around the school. We believe color trash can help change the behaviors of students and keep our school looking clean and safe. The color trash bin can help influence student behavior because student to recognize where to place their trash. Just like any traffic light around the world, when drivers see a red light they will come to a stop or when they see a green light they will go. Our hope is to make our school look cleaner than before and to help change student behaviors for the betterment of our school
