“数学是训练思维的体操”.题型变式往往指题目变式(多题一解)与方法变式(一题多解)的综合.在初中数学学习过程中,同学们应当根据合理的问题变式来体会蕴藏在数学问题中的“生命”价值,把知识学活,举一反三、触类旁通,产生学习的“最佳动机”和激发自己的灵感.题型变式能升华同学们的思维,为后续学习创造更好的条件、打 “Maths are training gymnastics thinking ” .Type of the questions often refers to the combination of the topic variant (multiple questions and answers) and method variants (one question and multiple solutions) .In junior high school mathematics learning process, students should be based on Reasonable problem variants to understand the value of “life” hidden in mathematical problems, the knowledge of learning from one case to another, by analogy, resulting in learning “best motivation ” and stimulate their own inspiration.
