陶行知先生说过:“行是知之路,学非问不明。”问题是数学的心脏,是学生思维的引擎。数学课堂少不了提问,数学课堂提问的优劣不仅表现在提问者的语气、问题呈现的方式等方面,更重要的体现在问题思维含量的高低。优质高效的问题应当饱含一定的思维深度,具有高附加值的思维含金量,对学生有着较高的启发性与挑战性。有些教师在课堂教学中提问的频率也不少,可是多数问题毫无价值,原因在于问题过于机械简单,缺乏一定的思维含量,对学生的学习并无 Mr. Tao Xingzhi said: “The line is the way of knowing, learning is not clear.” The problem is the heart of mathematics, the engine of student thinking. Mathematical classroom indispensable questions, the pros and cons of mathematical questions in the classroom not only in the tone of the questioner, the way the problem is presented, but also more importantly reflected in the level of question thinking. High quality and efficiency of the problem should be full of a certain depth of thinking, with high value-added thinking of the gold, the students have a higher heuristic and challenging. Some teachers in the classroom teaching a lot of questions, but most of the problems worthless, because the problem is too mechanical, lack of a certain amount of thinking, the students did not learn
