The construction of national first-class undergraduate courses is the foundation of national first-class professional construction and an important component of the construction of New Agricultural Sciences.In the context of the construction of New Agricultural Science,it is imperative to promote the reform and innovation of traditional agricultural talent training models.The construction of first-class courses promotes the teaching reform of Plant Physiology courses.The theory of deep learning proposes the cultivation of students'higher-level thinking ability,guides students to effectively learn,forms positive internal learning motivation,deep-level understanding,construction,reflection,and transfer of knowledge,and solves specific complex problems.In the process of teaching reform in Plant Physiology,the theory of deep learning has been applied,adhering to the student-centered educational philosophy,and constructing a task-oriented teaching model.We are committed to cultivating students'high-level thinking qualities,building confidence in contributing to agricultural development,enabling students to immerse themselves in specific problems concerning agricultural production and use knowledge to solve them,achieving the goal of applying what they have learned,and ultimately achieving deep learning for students.
