增长率是百分比应用中较难解决的问题。笔者在教学过程中发现,关于增长率的列方程和解应用题的内容是介于中小学相关知识链中既有联系又有区别的内容。若能将关于此知识点的中小学教学在教学内容和培养能力上进行有效衔接和整合,将有利于学生构建完整清晰的数学知识体系。一内容上的衔接与疏通俗话说:“知己知彼,百战不殆。”教师只有深入了解不同学段的不同要求,比较中小学数学的异同,注重相同领域的教学内容在不同学段的教学目标和要求,把握各学段之间联系的紧密性、合理性,才能更好地完成教学任务。
The growth rate is a problem that is more difficult to solve in percentage applications. The author found in the teaching process that the contents of the application of the column equation for solving the growth rate on the growth rate are related and differentiated content in the related knowledge chain of primary and secondary schools. If the primary and secondary teaching on this point of knowledge can be effectively connected and integrated in teaching content and training ability, it will help students to build a complete and clear mathematical knowledge system. A content on the convergence and dredge the saying goes: “Know thyself, know yourself. ” Teachers only have a deep understanding of the different requirements of different sections, compare the similarities and differences between primary and secondary mathematics, pay attention to the same field of teaching content in different sections of the teaching objectives and Requirements, grasp the closeness between the various sections, the rationality, in order to better complete the teaching task.
