一、问题的提出(一)课堂现状引发的思考2012年12月,笔者在学校进行了一项有关传统课堂中教师提问数量的调查研究,结果如下:图1七一小学四节数学研究课提问数量统计图从上述调查统计图中可以发现,教师提问最多的一节课是提出了166个问题,平均每分钟4个问题,四节课平均提问也高达90余次,平均每分钟提出2.3个问题。这是典型的师问生答的课堂!学生在课堂上没有问题、没有质疑、没有争论,缺乏激烈的思辨,回答问题成为学生主要的学习方式。
First, the issue raised (a) the current situation triggered by the classroom in December 2012, the author conducted a school in the traditional classroom teachers questioned the number of questions, the results are as follows: Figure 1 July 4 primary four mathematics research questions Quantitative Statistics From the above survey, we can see that the most frequently asked class of teachers is asking 166 questions, with an average of 4 questions per minute. The average number of questions in each of the four lessons is as high as 90, and the average number of questions per second is 2.3 problem. This is a typical teacher’s question and answer class! Students in the classroom no problem, no question, no argument, lack of fierce speculation, answering questions become the main way of learning students.
