At school, students are not only interested in learning and books. But you still have to pay attention to many other issues. In particular, it is impossible not to mention the issue of keeping the classroom clean. This is not a new or huge problem. All students since first grade have heard and done activities to keep the classroom clean. Like cleaning the classroom, wiping the tables and chairs, throwing trash in the bin. These actions not only help keep the classroom clean, but also help train students' self-discipline and attitude. Although it is not a difficult or heavy job, there are still some students who have not noticed and followed the common spirit. The children did not participate in the cleaning of the classroom, littering... That action brought down the collective morale. Making classroom cleanliness hinder. At the same time, gradually creating a lazy personality, lack of seriousness in collective activities. Therefore, we need to pay attention to promoting the spirit of self-interest and maintaining classroom hygiene in each student. From propaganda hours about the meaning and role of hygiene activities, to specific assignments and reminders to create habits for children. From there, we will form a community of students with a high sense of class hygiene. Help train the children, and at the same time create a clean and cool learning environment.
