Teachers should strengthen the management of students on duty, refine the health work into details, and let students know their health responsibilities. The team leader on duty and the Labor Committee are responsible for inspection every day. In addition to school inspections, teachers should also conduct spot checks at any time, and if they find bad health conditions, they should implement their responsibilities in time and make rectification or punishment. Avoid the phenomenon that hygiene can only be better when the school is inspected every day. Students who have made "outstanding contributions" to the class health work can get extra points if a set of evaluation system of rewards and punishments for littering is established in the class, and they actively participate in cleaning and do a good job in hygiene. If the performance is not good, it is necessary to reform through labor and deduct points. Then a good atmosphere of mutual supervision will be established in the class. It is essential to set a good example of caring for the environment in the class, and the teacher's example is even more indispensable. When you see a piece of paper, you can bend down and pick it up. Moreover, class cadres are required to set an example, form a good atmosphere and influence each other. It is also necessary to enhance students' health awareness through activities and theme class meetings. Usually, we should publicize more health knowledge and engage in more environmental protection activities, so that students can learn to turn waste into treasure. Moreover, through the publicity of the harm of global environmental pollution, students can understand the current situation of the earth where we live, educate them in terms of ideas and habits, and call on everyone to jointly safeguard our living environment. We can also stimulate students' self-esteem by comparing the performance of good health awareness in some foreign countries. Let students understand the importance of environmental protection and form a positive public opinion atmosphere. You can post some eye-catching warning signs or signs all over the campus, and students will properly restrain their behavior and achieve the purpose of regulating their behavior when there is a clear request for prompt. Moreover, more beautiful and eye-catching trash cans should be set up to prevent students from throwing garbage casually because they are troublesome or disrespectful. If there are littering students who take photos for evidence collection, when supervising and publicizing environmental protection work, they can provide the time and place for students' union or setting up environmental protection guards, and encourage other students to take photos with digital cameras or mobile phones for evidence collection. After verification, they can get rewards. And forensic photos will be published for a semester. Or install monitoring equipment in the whole school to monitor the campus, and do not collect evidence, verify and publicize it regularly. In short, people think that littering may be caught, and if caught, they will be severely punished. Encourage everyone to participate in supervision by setting rewards, and strengthen the possibility of being caught throwing garbage. I think it will take a long time to completely change the phenomenon of littering. Before the development of environmental protection behavior, we must strengthen the norms and try our best to facilitate students' lives. Moreover, the formation of this behavior habit is inseparable from the influence of family and society.
