数学学习是一个循序渐进的过程,随着学习的不断深入,我们所学到的知识也越来越多,因此就要经常对这些知识进行梳理。这样不但能全面检查自己所掌握的知识是否有缺漏,还可以在“查缺补漏”的基础上弄清知识之间的演变和发展,以及各知识之间的联系和区别。如果我们边学边梳理,就会发现新旧知识之间存在以下几个特点:一、新知识扩充并丰富了旧知识,旧知识的一些特性依然会适用于新知识。但新 Mathematics learning is a gradual process. With the continuous deepening of learning, we have learned more and more knowledge, so we must sort out the knowledge constantly. In this way, not only can we fully check whether there is any omission in the knowledge we hold, we can also clarify the evolution and development of knowledge and the connection and difference between the knowledge on the basis of “lack of inspection”. If we learn while studying, we find that there are some characteristics between old and new knowledge: First, new knowledge expands and enriches old knowledge. Some features of old knowledge will still apply to new knowledge. But new
