I will definitely agree that students will learn more when they have discussions.
Take me as an example, I still remember clearly the spring of 2003 when SARS attacked our city, students were not allowed to study in the classrooms together, and we had to go home and learned separately by on-line courses. So I have no partners to discuss with, and I got the lowest average GPA that semester. I think that's all because I did not understand pretty well without discussions with my teacher or classmates.

我非常同意学生们通过讨论可以学到更多知识。
以我为例,我仍然清楚地记得2003年那个春天非典在我们的城市肆虐的情景, 那时学生们不允许在教室一起学习,我们必须回家通过在线课程单独学习。 所以我没有伙伴可以讨论问题,那学期我拿到了最低平均成绩。 我认为这是因为没有很好地与老师或同学讨论所学的知识，我理解不深造成的。
