As one of the important core courses in the major of urban and rural planning and architecture in the new era, urban design plays a key role in the process of cultivating high-skilled and compound talents suitable for the new era. This article takes the "Implementation Opinions on the Construction of First-class Undergraduate Courses" issued by the Ministry of Education on October 30, 2019 (Jiaogao [2019] No. 8) as an opportunity to reform the traditional teaching methods of urban design courses. Online teaching is adopted under the mixed teaching mode. SPOC new technical methods were added to the urban design theory class and the curriculum design to assist teaching. The integration of "classroom teaching, observation teaching, experimental teaching, practical teaching, academic lectures, and case teaching" was proposed to construct an innovative teaching model of "SPOC + project + competition" trinity and to realize the combination of students' online independent learning and offline teaching, thus students' independent learning ability and practical ability of on-site engineering thinking would be effectively improved.
