The way of curriculum assessment is closely related to the quality of teaching, and assessment mode can affect graduates' learning style. This paper puts forward the goal and orientation of graduate teaching and learning, explores the application of multiple complementary teaching model and supplemented multiple assessment, in order to promote the truly implementation of multiple complementary "teaching" and "learning" modes and test their effects. Taking the course of building energy efficiency technology as an example, it is a beneficial practice for the teaching reform of engineering graduate education, to highlight the changes of teachers' teaching methods and students' learning style, to fully implement diversified assessment, to promote the development of students' multiple intelligences, to pay attention to the cultivation of thinking habits, to improve their autonomous learning and innovation ability, and to help graduate students to clear their development direction and establish long-term goals.
