The sudden rise of study travel is due to the Opinions on Promoting Study Travel for Primary and Secondary School Students jointly issued by the Ministry of Education and other 1 1 departments in 20 16, which clearly stated that it is necessary to promote the healthy and rapid development of study travel. Before, the school was not keen on organizing students to hold off-campus practical activities, mainly because the responsibility risk was too great. Off-campus is nothing more than a closed campus, with one mountain, one water, one grass and one tree. In the eyes of schools and teachers, it is full of danger. If you are not careful, students will be in big trouble when they bump into each other. To put it mildly, some parents and teachers have become accustomed to school. When a student is injured, the Lions will ask for compensation regardless of who is responsible. If he doesn't meet his demands, he will petition, block the school gate and make trouble. The school can't stand the pressure and can only spend money to eliminate disasters. Research travel is not an ordinary off-campus activity, with large scale, long distance and greater unpredictable risks. Without policy support, schools generally dare not organize such activities. Now, with the support of policies, study tour is another form of education and teaching, and more schools are carrying out study tour. For students, participating in this kind of collective activity is helpful to cultivate team spirit and exercise self-care ability, which is not only fun, but also makes the knowledge in textbooks vivid and beneficial.
