Blackboard writing undertakes the dual task of knowledge transmission and classroom culture inheritance. Well-designed blackboard writing will not only help students to better memorize, understand and construct knowledge framework, but also create a serious but lively classroom atmosphere, strengthen the soul of moral education in the classroom, leading to improved quality of education. Taking the practice of blackboard writing in teaching the Biochemistry course as an example, the authors categorized the blackboard writing approaches according to the teaching objectives to be achieved, and discussed the necessity and application scope of each type of blackboard writing approach in the multimedia era. Our goal was to make blackboard writing, a conventional teaching approach, play an important role in the new era of classroom education.
