Abstract: The new round of scientific and technological revolution, industrial reform and the development of new economic model have put forward a new challenge to the reform and development of engineering education in China. In the context of new engineering construction, this paper is based on the discussion on teaching reform of the core courses of postgraduates of landscape architecture in Tongji University, and proposes that landscape architecture theory teaching, especially in the process of graduate teaching, should pay more attention to the turn of teaching thinking in the leadership, integration, renovation and inter-discipline aspects, and further explore renovation of teaching approaches and learning paths based on the philosophy of meta-thinking. They include the following aspects: 1) a focus on “relevance expansion” to build a professional learning system based on knowledge structure; 2) a focus on “learning in order to practise” to realize professional learning progress based on practice renovation; and 3) a focus on “cross-disciplinary integration” to develop professional critical thinking based on knowledge origins. Finally, this paper summarizes the teaching outcomes and suggestions based on 97 questionnaires in three consecutive years, putting forward further optimization strategies for theoretical teaching.
