在听课过程中,我们时常看到这种现象:一些教师将学生分为“重点”与“非重点”,不论是课堂提问、指名板演,还是课堂上的其他“重大活动”,都乐意让那些听话的学习好的“重点”学生去做,使得相当一部分“非重点”学生“靠边站”,没有表现自己的机会.教师偏爱少数学生,而疏远其他学生,不利于调动学生学习的积极性,使教与学的双边活动不能在和谐的气氛中进行,影响了教学任务的完成. During the course of lectures, we often see this phenomenon: Some teachers divide students into “key points” and “non-key points”. Whether they ask questions in classrooms, specify board games, or other “major events” in class, they are happy to let Those obedient and well-educated “key students” do a lot of “non-key” students to “stand by” and do not show their own opportunities. Teachers prefer a small number of students, while alienating other students is not conducive to mobilizing students’ enthusiasm for learning. The bilateral activities of teaching and learning cannot be conducted in a harmonious atmosphere, which affects the completion of teaching tasks.
