In the above table, it is found that the average sentient analysis score of the second discussion is the lowest in three weeks. Therefore, the content of this week is reviewed. As shown in the figure, it is found that the students' speeches in this week are more radical, and there are more negative words than those in the other two weeks, such as: don't interrupt, can't use, the angle is not right, etc., which leads to the lower sentient analysis score of this week after calculation.
