由于初、高中教材之间的跨度大,因此搞好高中数学起始部分即集合知识的学习就显得至关重要.高一同学因学习方法的不适应,对集合的概念缺乏深刻的理解,解题时考虑不周的现象屡见不鲜.他们往往不能把给出的集合表达式转化成相关的数学知识,致使解题半途而废.针对这个薄弱环节,本文提出以下注意点. Because the span between primary and high school textbooks is large, it is of utmost importance to do well in the initial part of high school mathematics, that is, the collection of knowledge. The students in Grade One lack of a deep understanding of the concept of the collection due to the incompatibility of learning methods. It is not uncommon for problems to be considered at the time of the question. They often cannot convert the given set of expressions into related mathematical knowledge, resulting in the solution of the problem halfway. In response to this weak link, this article proposes the following points of attention.
