Our physics teacher is a special grade teacher, and also serves as the head of the grade department. Every time I see an unerased blackboard, he will kindly ask, “Which classmate is responsible for erasing the blackboard?” After the classmate in charge of erasing the blackboard stands up a little shame. He would smile and hand over the blackboard eraser, and add, “Thanks for your hard work today!” The English teacher is the head teacher, and the few clever ghosts sitting in the front row will get up the moment she enters the classroom. Wipe the blackboard clean. A Chinese teacher can understand what it means just as a representative of the eye class. The biology teacher is a bit menopausal, as long as there are other teachers’ handwriting on the blackboard, he immediately droops his face down: “No class today, you do your own questions, come and ask if you don’t understand.” Then he turned and walked back to the biology office next door to the classroom. The chemistry teacher likes to read: “You talk about the blackboard in your class, but no one wipes it. I don’t know if it is for me or every class. The blackboard in Class 15 is bright and bright, your pearl class Students are not as good as others in the experimental class.” When a classmate vigorously wiped off the marks left by the previous class, she still did not forget to pinch her nose and vomit: “If you wipe it slowly, I won’t eat you. Look. Look at the end of the chalk on this podium. If I have bronchitis, you have to pay to treat me!” The math teacher is young and handsome, witty and kind. He won’t even wrinkle his brows when he sees the messy blackboard. He is very knowledgeable and not only does he wipe the blackboard clean himself, he always talks to us about the content of the previous lecture on the blackboard. The humorous words often make us laugh. The students like math teachers the most.
I usually first ask whether the things on the blackboard are used up. Sometimes the homework left by the head teacher, the sample questions copied by the students have not been copied, and they are left there on purpose. If you wipe the child, you have to borrow other students. You will be criticized if you can’t borrow it. It is not a good feeling for me to be a subject teacher to go to a class and let the child be scolded. In this case, I only use the whiteboard. If the student on duty really forgets to wipe it, I usually wipe it by myself. After all, the bell is ringing. The children wipe it so slowly that it is impossible for everyone to wait for him to wipe the blackboard. He may need to wipe it for five minutes. Teachers have different ways to deal with this kind of thing. Old teachers usually ask students to wipe it directly. Sometimes it’s not because of being up high, but because of frozen shoulder, which makes it difficult to lift the arm.
