Classroom, it cannot and cannot become a "vacuum". Because of this, there is no classroom without "accident", and it is also regrettable that the classroom with "accident" cannot be handled properly. What should we do in the face of "accidents"? I think, for example, every "accident" is actually a "judgment question" to test teachers' teaching quality and teaching tact. Whether to "turn left" or "turn right" requires us to make a "spiritual choice". Of course, it is also faced with "accidents". Some teachers can make full use of it and achieve quite high results, while others can only be "hit on the waist". Why is there such a difference? The key is that teachers must be "always ready", that is to say, they must constantly improve their teaching skills and even their humanistic qualities.
