教学中,面对课本中“你是怎样想的?你喜欢哪种方法”的表述,面对教师用书中“不管学生用的是哪一种方法,只要有道理,教师就应该尊重学生的方法,给予充分的肯定”的说法,我总感到有些难以把握。是否真随学生选择一种喜欢的就可以了呢?哪些方法又是学生必须要掌握的?这些方法的地位和功能一样吗?带着这些问题,我对人教版教材的各种多样化算法进行了分析,试图看清纷繁背后的数学本质,让学生扎实地学好数学。一、思维水平的差异教材中有些例题显现的多种解题方法隐含着从 Teaching, the face of the textbook “How do you think? Which way do you like?”, Facing the teacher’s book “Regardless of the student is using what method, as long as the truth, teachers should respect Student approach, give full affirmation ”, I always feel a bit difficult to grasp. With the students really choose a favorite on it? What methods are students have to master? The status and function of these methods the same? With these questions, I teach people a variety of teaching materials, algorithms Analyzed in an attempt to see the math behind the complex, let students learn mathematics solidly. First, the difference between the level of thinking Some examples of teaching materials appear in a variety of problem-solving methods implied from
