集合是数学和现代思维学中的一个重要概念,它与各学科有着广泛的联系,中学生在高一代数学中已系统学过集合的基本概念及其运用,在化学中引用集合概念描述物质的属性、概念的内涵和外延具有生动、严密、直观等优点,有利于培养学生逻辑思维能力和抽象思维能力,有利于激发和保持学生学习化学的兴趣。以下就谈谈集合在化学教学中的一些运用。 Collections are an important concept in mathematics and modern thinking. They have extensive connections with various disciplines. Middle school students have systematically studied the basic concepts of collections and their applications in higher generation mathematics. They use set concepts to describe the properties of substances in chemistry. The connotation and denotation of the concept are vivid, rigorous, and intuitive, which is conducive to the cultivation of students’ logical thinking ability and abstract thinking ability, and is conducive to stimulating and keeping students’ interest in learning chemistry. Let’s talk about some of the uses of the collection in chemistry teaching.
