调查研究显示,变量代换方法在中职数学解题中的应用频率较高,对学生灵活解题、培养学生思维能力、提高教学质量等都具有积极的意义。在中职数学教学中,变量代换解题法的影响主要体现在两个方面:一是已学习知识对另一种知识的影响;二是现有的思维方式、学习能力对其他知识学习的影响。笔者根据教学经验,并结合相关文献资料对变量代换解题 Survey and research shows that the variable substitution method has a high frequency of application in solving mathematical problems in secondary vocational schools, which has positive significance for students to solve problems flexibly, train their thinking ability and improve their teaching quality. In the teaching of mathematics in secondary vocational schools, the influence of the variable substitution problem-solving method is mainly reflected in two aspects: one is the influence of learned knowledge on another; the other is the existing way of thinking and learning ability to other knowledge learning influences. According to the author’s teaching experience, combined with relevant literature on the variable substitution problem-solving
