ABSTRACT
"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.
ABSTRACT
Comprehensive experiments course is a bridge for higher vocational students to integrate theoretical knowledge with production practice. The article introduces that our biological pharmacy department is committed to the principles of "promotion of teaching, learning and construction through skills competition so as to integrate education and training". By taking penicillin fermentation process as an example, reform has been made in several aspects including teaching objectives, teaching content and teaching methods. We integrate the practical operation of fermentation equipment with virtual simulation software to develop a two-way interactive course. By reducing the subjective dependence, the quantitative management and evaluation of fermentation process parameter control were put into place, which efficiently integrated the skills competition with practical teaching. Improved teaching performance has been achieved over recent years, which may facilitate the reform and practice of similar courses based on skills competition.
