Recently, in order to tie in with the teaching theory, we went to Guangzhou to attend lectures. The minutes and comments of the following lectures were a mathematics lesson conducted by Xiao Jie on the third day of class (5). The topic was “straight and round Positional relationship”. First, the lesson record teaching process; (A) the introduction of a new lesson Teacher: We have learned the point and the location of the circle.
