“错”其实是小学数学课堂学习必然的产物,甚至我们可以说没有错误的课堂教学是一种无效的教学。在学生的错误中,往往蕴含着高价值的教学资源,往往暗藏着学生不同的思考、学生的学习习惯,闪烁着学生智慧的火花。那么,作为数学教师如何进行有效的智慧调控,利用好学生错误资源中有价值的因素,达到错误中开出智慧之花的神奇效果呢?下面笔者将通过几个案例进行具体的阐述。一、“预”见错误,精心预设,错误在 “False ” is actually an inevitable product of primary school mathematics learning, and even we can say that there is no mistake in classroom teaching is an invalid teaching. In the mistakes of students, often contains high value teaching resources, often hidden in different thinking students, students’ learning habits, flashing the spark of student wisdom. So, as mathematics teachers how to carry out effective regulation of intelligence, make good use of the valuable factors in the wrong students resources to achieve the miraculous effect of the flower of wisdom out of error? The author will be elaborated in several cases through the following. First, “Pre ” see the error, carefully preset, the error in
