First, the question put forward to improve the quality of biological experimental teaching is a common concern of biology teachers. This experiment made a preliminary study on the application of video recording in biology experiment teaching, and provided some convincing facts for the popularization of electrochemical education. The situation is reported below. Second, the methods and processes are mainly single-factor rotation test and other groups, and to assist the investigation and observation. 1. Subjects: Select high school one (2), one (3) for the experimental class to remove the two classes of homework poor students, the experiment
