目前,许多地区正如火如荼地打造高效的小学数学课堂教学。高效课堂的关注点大多放在如何尽可能地减少教师的讲授时间,把时间还给学生,发挥学生的自主性,挖掘学生自身的潜力,达到高效学习之目的。有的地区明确规定“教师连续讲授时间不得超过一定的分钟数”、“先让学生尝试,教师不得先讲”等等。笔者在从事教学管理中发现,有的教师为了不超 At present, many areas are in full swing to create efficient primary mathematics classroom teaching. Efficient classroom focus mostly on how to minimize teacher teaching time, the time back to students, give play to the autonomy of students, tap the potential of students themselves, to achieve the purpose of efficient learning. In some areas, it is explicitly stipulated that teachers should not spend more than a certain number of minutes in a row for consecutive lectures, let students try first, teachers should not speak first, and so on. I was engaged in teaching management found that some teachers in order not to exceed
