Abstract: Biochemistry experiment courses are important practical courses for medical specialties. Traditional teach-ling has the problems of single teaching method, insufficient student participation, weak learning enthusiasm, and no assessment method. Comprehensive experiment is a teaching method that takes students as the main body and uses relevant theoretical knowledge and practical operation skills to solve specific experimental problems. In the teaching process, the assessment is used as an experiment course test method, which not only urges students to complete the experimental content seriously, but also can reduce students' slack in the experiment course. The introduction of comprehensive experiments into biochemistry experiment teaching is expected to improve the quality of teaching and enhance students' capacity building of practice guided by theoretical knowledge, clinical skills and independent thinking.

Key words: biochemistry experiment teaching, comprehensive experiment, experimental assessment, micro-lesson
