Abstract: In view of the problems existing in the experimental teaching of garden plant protection, such as the single experimental project, the templated experimental process, the traditional experimental method, and the tense experimental time, based on the analysis of the current situation of the experimental teaching of this course, the research group took the teaching task as the starting point,and carried out the exploration and practice of the project-based experimental teaching of garden plant protection from the aspects of teaching content, implementation methods, evaluation and assessment. The results show that the task-driven project-based experimental teaching reform not only cultivates students’ innovative awareness and ability, but also improves teaching quality and teaching effect, and has a certain exemplary role in the transformation and reform of passive teaching to active teaching.
