Our country is in the process of transformation and development and the improvement of territorial and spatial planning. Regulatory detailed planning (hereinafter referred to as regulatory planning) is a key link in the five-level and three-category system of territorial and spatial planning. A compulsory course for undergraduates majoring in planning, in the context of the new land and space planning, the teaching concept of OBE is introduced to explore the teaching optimization of the course. Since 2020, the “Control Regulations” course has kept pace with the times, and has undergone major adjustments and teaching optimization. The previous pure design course has been adjusted to a theoretical course + design teaching. The two stages are completed together. Theories appear during the course operation. The two main problems are the lack of smooth connection between curriculum and design teaching, and the disconnection between teaching and industry practice. Guided by the relevant norms, standards and guidelines for national and local land and space planning, it mainly optimizes and updates the teaching content and adjustment of hours in the theoretical part; introduces the concept of OBE, and takes measures from three dimensions starting from the two roles of teachers and students Optimize the teaching process of design courses. They are the whole process control and flip guidance of the “1+1+1” of the teacher team, the participation, collaboration and autonomous internalization of the whole design process of the “1+1+1” of the student group, the autonomous feedback and the cooperation of the student group + teaching team. The improvement of the whole process evaluation mechanism. Emphasizing that continuous improvement is another important connotation of the OBE concept, the reform and optimization of the “Control Regulations” course will continue to be carried out under new opportunities and challenges, serving the training of urban and rural planning professionals and the construction of high-quality living environment.
