November 17th Class reflection

In chapter 15 of HDB, we learned classroom management. The author suggested followings.
First, the teachers have to make physical comfortable place. Second, the teachers have to arrange the desks in order to make the students interact each other. Third, the teachers have to know how to use the chalkboard effectively. Fourth, the teachers have to prepare well. Fifth the author mentions about our rate of speech. Even though the students do not understand what the teacher said, the teacher should not decrease their rate of speech. The teacher should speak just clearly. Sixth, when the teacher encounter unexpected situation, the teachers should poise. In the last part, the author mentions about balancing praise and criticism. I think that if the balanced is collapsed, it is hard for the teachers to teach, so we need to know how to keep balance effectively.
In this chapter, the author mentions about what we teacher can not controll. For example, the class size. In Japan we ordinary have 40 students in one class. Besides this, we have to take care deeply.
