教师要善于挖掘教材,不要总是以标准答案束缚学生的思维,而应多采用恰当方法训练学生思维,让其形成多元视角,才能有利于求异思维的培养,渐渐形成求异的能力,从而使学生感受到数学的严谨和灵活。求异思维是指大脑在思维时呈现的一种扩散状态的思维模式,它表现为思维视野广阔,思维呈现出多维发散状。如,“一题多解”、“一事多写”、“一物多用”等方式,培养发散思维能力。像我们所熟知的晏子使楚、曹冲称象等故事就是摆脱定式思维采用求异思维 Teachers should be good at mining textbooks, do not always use the standard answer to strangle the thinking of students, and should use more appropriate methods of training students thinking, allowing them to form a multi-perspective in order to facilitate the cultivation of different thinking, and gradually form the ability to seek differences Make students feel math rigorous and flexible. Difference thinking refers to the brain in the thinking of a state of diffusion mode of thinking, which showed a wide range of thinking, thinking, showing a multidimensional divergence. For example, “a problem more solution”, “more than one thing to write ”, “a multi-purpose ” and other ways to cultivate divergent thinking ability. As we know Yanzi Chu, Cao Chong said the story is to get rid of the stereotyped thinking using different thinking
