初一学生运算中的错误很多。学生运算上出错,要从思维上找原因。我在教学中坚持两点:一是尽量降低教学的起点,使多数学生的思维能适应;二是延长思维发展的过程,使学生有一个比较充分的认识过程。从这两点出发,努力提高讲练的效率,培养学生的运算能力。教学中的起点是针对学生的基础而言的。有些差生常常反映听不懂,其原因多数是基础跟不上。例如单项式的乘除法没有学好,学习多项式的乘除法 There are a lot of mistakes in the first-year student operations. Students make mistakes, from the thinking to find the reason. I insisted in teaching two things: First, try to reduce the starting point for teaching, so that most students can adapt to the thinking; the second is to extend the process of thinking and development, so that students have a more adequate understanding of the process. Starting from these two points, we should strive to improve the efficiency of training and cultivate students' computing power. The starting point in teaching is for the student's foundation. Some poor students often do not understand, most of the reasons are not keep up. For example, the monomial multiplication and division did not learn well, learning polynomial multiplication and division
