随着“双减”政策实施，课后服务的主要场所从校外培训机构逐步转移至中小学校内，学校成为课后服务实施的主阵地，教师成为课后服务的主要参与者，承担起课后服务的主要工作。高质量的课后服务离不开高素质的师资队伍。但是，在具体实践过程中，中小学课后服务却面临着师资数量不足、素质不齐、负担不减、管理不善等诸多困境。因此，本文在深入分析教师参与课后服务的困境的基础上提出若干建议，以期在一定程度上破解师资困境，促进课后服务高质量发展。

With the implementation of the “double-reduction” policy, the main venue for after-school services has gradually shifted from out-of-school training institutions to primary and secondary schools, and schools have become the main venue for the implementation of after-school services, while teachers have become the main participants in after-school services and have taken on the main work of after-school services. High-quality after-school services cannot be separated from high-quality teachers. However, in the process of specific practice, after-school services in schools are faced with many difficulties such as an insufficient number of teachers, unequal quality, unreduced burden, poor management and so on. Therefore, this paper puts forward suggestions on the basis of in-depth analysis of the dilemma of teachers in the implementation of after-school service, in order to break the dilemma of teachers to a certain extent, and promote the development of high quality after-school service.
