经过几十年的教学实践,我们发现有相当一部分学生计算的正确率低,速度慢,特别是到了高年级,由于计算能力差对这些学生的数学学习造成了一定的影响。是什么原因造成的这种现象?我认为主要有以下几方面原因:第一,教师在教学中不注重引导学生归纳计算方法。苏教版课程标准数学实验教材变换了法则的呈现方式,注重让学生在探索计算方法的过程中,自主形成对计算方法的感悟,并能通过交流加以明确。在实际教学中,教师往往注意让学生自主探索算法,
After several decades of teaching practice, we found that a considerable proportion of students calculated the correct rate is low, slow, especially to the upper grades, due to poor computing power of these students have a certain impact on math learning. What causes this phenomenon? I think the main reasons for the following aspects: First, teachers do not pay attention to guide students in inducing calculation methods. The curriculum standard mathematics experiment teaching material of Sujiao Edition changes the way of presenting the law, and focuses on allowing students to comprehend the calculation method autonomously in the process of exploring the calculation method and can make it clear through the exchange. In the actual teaching, teachers often pay attention to let students explore algorithms independently,
