有效教学的基本状态是对话式、互动式的,而教学是否出现和维持某种对话式、互动式的状态取决于教师是否能够有效地“提问”。只有在问题设计时以教学目标为导向,以问题情景为手段,并以学生实际为依托,面向全体,考虑问题的启发性、适度性、层次性、开放性等原则,教师的提问才能引导学生学得更轻松、高效,课堂效益才能得到真正的提高。 The basic state of effective teaching is dialogue and interactive, and whether or not teaching occurs and maintains a dialogue or interactive state depends on whether the teacher can effectively “question”. Only when the problem is designed with the teaching goal as the guide and the problem scenario as the means and based on the actual situation of the students and the whole, considering the principles of enlightenment, appropriateness, level, and openness, teachers’ questions can guide students. It is easier and more effective to learn, and classroom efficiency can be truly improved.
