著名教育家陶行知说:“发明千千万,起点是一问……智者问得巧,愚者问得笨。”提问是课堂教学的重要手段之一。如果教师在课堂向学生提出有价值的、能激起学生思维剧烈活动的问题,往往比引导学生解决问题更重要。数学课堂教学的效果在很大程度上也就取决于教师的有效引问。关注数学课堂教师引问的有效性,应该是每位数学老师必须重视的问题。
Famous educator Tao Xingzhi said: “invented tens of millions, the starting point is a question ... ... smarter asked dexterity, fool asked stupid. ” Questions are one of the important means of classroom teaching. If teachers in the classroom put forward to students valuable, can stimulate students to think violent activities of the problem, often than guide students to solve the problem is more important. To a large extent, the effect of math classroom teaching also depends on the effective citation of teachers. Paying attention to the validity of the math class teacher’s quotation should be a problem that every math teacher must pay attention to.
