According to the talent training objectives and teaching syllabus of applied statistics major, combined with the students’ job requirements, this paper starts with the practical characteristics of sample survey courses, and constructs a three-dimensional oriented teaching model based on PAD class with statistical behavior ability as the core. Firstly, this paper divides the teaching process into three parts: theoretical teaching, experimental teaching and practical teaching. It aims to implement the three-dimensional guidance-oriented teaching in the form of cooperative learning, design-oriented learning and project-based learning; Secondly, restructure the teaching content by dividing it into three modules: theory, experiment and application, which will provide strong support for realizing the three-dimensional-oriented teaching; Finally, a three-dimensional hierarchical evaluation system is constructed to form a multi-dimensional teaching evaluation matrix integrating process evaluation and developmental ability diagnosis, which provides strong support for better teaching.
