在小学数学教学中,由于种种原因,学生常常会犯很多始料未及的错误。然而,由于教师怕学生出错而影响教学节奏,所以针对这些错误,常常采取忽略、回避的态度。个别教师认为,对于学生的错误,如果用课堂上宝贵的35分钟来处理,对学生而言简直是浪费。结果,这些错误未能得到妥善处理,导致学生无法吸取教训。其实,对于这些错误,如果能进一步分析一下原因,并透过错误发现症结所在,利用错误这一资源为教学服务,可能会变“废”为“宝”。 In elementary mathematics teaching, students often commit many unexpected mistakes for various reasons. However, because teachers are afraid of students’ mistakes and affect the teaching rhythm, so these mistakes are often ignored and avoided. Individual teachers think that if students’ mistakes are handled in class for 35 minutes, it is actually a waste for students. As a result, these mistakes have not been properly handled, leaving students unable to learn the lesson. In fact, for these mistakes, if we can further analyze the reasons and find the crux of the problem by mistake, using the resources of mistakes for teaching services may change “waste” to “treasure.”
