新《课程标准》中指出:“有效的学习活动不能单纯地依靠模仿与记忆,教师应引导学生主动地从事观察、实验、猜测、验证、推理与交流等数学活动,从而使学生形成自己对数学知识的理解和有效的学习策略”.应用题的教学往往由于题目本身相对独立、内容枯燥、信息量大而成为教师教学 The new “Course Standard” states: “Effective learning activities cannot rely solely on imitation and memory. Teachers should guide students to actively engage in mathematical activities such as observation, experimentation, guessing, verification, reasoning and communication, so that students can form their own mathematics. The understanding of knowledge and effective learning strategies”. The teaching of application problems is often due to the relatively independent title of the subject, the content is boring and the amount of information is large.
