课堂上，教师有时难免要批评学生，这是因为个别同学听课时注意力不集中，或交头接耳讲“悄悄话”，或你叩我敲做小动作，或精神外用看杂书，或萎靡不振打瞌睡。对他们及时给予批评是完全必要的。但采取何种批评方式效果更好，很值得斟酌研究。教师一般采用的方法是暂停讲课， In class, teachers are sometimes unavoidable to criticize students. This is because individual students are not attentive when listening to classes, or whispering “whispering”, or you call me to perform tricks, or look at books for mischief, or slumber. It is absolutely necessary to give them timely criticism. But what kind of criticism is better, it is worth considering research. The general method used by teachers is to suspend lectures.
