What is classroom questioning? What are the functions of classroom questioning? Give examples to illustrate what is a good classroom question.

Questioning is the main way of classroom teaching, which is often used at the beginning, during or at the end of teaching activities. For students, it can stimulate learning motivation, stimulate thinking and examine understanding ability. For teachers, it can play a role in checking teaching objectives and reorganizing teaching. In order to use questions correctly and appropriately, teachers should first have a clear understanding of the types of questions they ask, so as to make judgments and choices.
