"Flipped Classroom" is a new kind of "student-centered" teaching model, which can give full play to the advantages of both sides of teaching and learning. According to this teaching model, we redesigned the teaching process, in which the students studied by themselves and built their own knowledge system. Moreover, each of them took part in three stages of experimental design including digital signal collection, analysis and processing in groups. Results have shown that this model can fully stimulate students' learning interest, not only helps students to deepen understanding of digital signal processing theory knowledge, but also strengthen the ability of autonomous learning and team collaboration. The teaching model maybe have certain reference function in comprehensive experiment teaching of Digital Signal Processing course for biomedical engineering specialty.

Based on the summary and reflection of the existing course construction content, this paper redesigns the course teaching to Brain Functional Imaging and forms a new curriculum construction scheme, including improving the professional teachers' ability of the teaching team by means of "internal training" + "external introduction", building an online and offline integrated teaching mode by combining online teaching resources such as course website with offline teaching (such as literature guidance, classroom discussion, comprehensive experimental design, etc.), and designing comprehensive experiments related to Electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS), which is driven by scientific research projects, based on the scientific research experimental platform of the teaching and research department. This construction scheme is of great significance for improving the teaching quality of the course, stimulating the learning interest of graduate students, and cultivating the comprehensive application and practical innovation ability of graduate students' brain imaging technology. And it also provides the reference for the further construction of the course and teaching reform in the future.
