共学是指同学之间共同讨论,相互学习的一种学习方式,它和教学、自学是三维一体的。 在中学化学教学中,既要重视师生之间的纵向交流,也要重视学生与学生之间的横向交流,只有两者相结合,才能构成多向的课堂交流,才能收到良好的教学效果。 Co-study is a learning method in which the students discuss together and learn from each other. It is integrated with teaching and self-study. In chemistry teaching in middle schools, it is necessary to attach importance to the vertical communication between teachers and students, but also to the horizontal communication between students and students. Only when the two are combined can multi-directional classroom communication be formed in order to receive good teaching results. .
