RESUMEN
The training effects of experimental courses determine the practical abilities of undergraduate students. Therefore, it is essential to establish a comprehensive experimental course system that adapts to the undergraduate education of environmental science. Here, we introduce the "basic-specialized-comprehensive" experimental course system of Xiamen University, which is established following the principles of being systematic, comprehensive, and modular. To establish this course system, we first increased the investment of lab facilities and enhanced the management of student labs. Then, we improved the contexts of teaching and training according to the requirements of industry and society. Showing how this course system is developed stepwise and the training effects of this system, we hope to provide a reference for the experimental courses of environmental science in colleges and universities.
