Curriculum ideological and political construction, as a strategic measure to carry out the fundamental task of moral education, has become the main direction of major education and teaching reform in universities and majors across the country. As a core course of landscape architecture major in domestic universities, History of Chinese Gardens has an important mission of making students form correct historical and philosophical views, and should become the forefront of ideological and political construction of professional courses. Taking the curriculum teaching reform of History of Chinese Gardens in the landscape architecture major of Guangzhou university as an example, this paper put forward a path of curriculum ideological and political construction through 3 + 3 measures in class and after class, in order to promote the students learning, thinking, practice and comprehension, and to achieve the teaching goals of understanding the law of historical development, increasing confidence in garden art, advocating moral characters of loving the motherland and loving the people, and striving to apply professional skills to serve the country. Among them, the three major measures of “in class” are: 1) build a macro structure and give consideration to horizontal and vertical knowledge points; 2) use knowledge points to drive knowledge plate learning, and highlight details and key points; 3) review the old and learn from the new. The three measures “after class” are: 1) use tasks to drive student-led implementation; 2) set mandatory tasks and optional tasks to respect the individual differences of students; 3) use formative assessment to encourage students to compete. The exploration of relevant teaching reform has promoted the comprehensive realization of the knowledge goal, ability goal and value goal of the curriculum teaching, which can provide reference for the construction of the curriculum ideological and political construction of History of Chinese Gardens and related courses.
