College students' summer teaching activities are an active way of social participation, which can help them cultivate their sense of social responsibility and teamwork ability, and also help areas with scarce educational resources. This kind of activity usually helps to broaden students' horizons and improve their awareness of humanistic care. However, teaching activities need to be carried out under proper organization and guidance to ensure that the activities themselves have practical significance and avoid short-term assistance and neglect the long-term sustainable development of education. Therefore, while advocating, we should strengthen the supervision and evaluation of teaching support projects to ensure that they really have a positive impact on the beneficiary students.
