课堂教学离不开“问”，但目前课堂提问存在着不少“徒劳的提问”。提问可以分为教师课堂提问和学生提问两部分。常见有些教师不会提问或提问不能恰到好处，缺乏启发性，容易阻碍学生扩散思维的发展，挫伤学生学习的积极性，这就需要教师认真研究提问的目的、作用和方法，研究 Classroom teaching is inseparable from the “question”, but there are many “fun questions” in the classroom. Questions can be divided into two parts: teacher questioning and student questioning. Some common teachers who do not ask questions or ask questions cannot be justified or instructive. They tend to hinder the development of students' diffusion thinking and dampen students' enthusiasm for learning. This requires teachers to seriously study the purpose, role, and methods of asking questions.
