| "Numbers and algebra" is one of the important components of junior high school mathematics curriculum.Rational numbers are the important basis for the content of "numbers and algebra" and also provide guarantees for the effective learning of subsequent knowledge,such as inequalities,equations and functions.However,the rational number learning effect of many students is not ideal,mainly because there are some common mistakes in rational number learning that are not taken seriously.If these mistakes are not corrected in time,they will inevitably cause difficulties in the study of rational numbers and even subsequent knowledge.This thesis mainly studies the typical mistakes and teaching countermeasures in the learning process of rational number for the middle school students.The first chapter mainly introduces the research background,significance,research ideas and technical route.The second chapter briefly describes the domestic and foreign research on rational number error analysis and teaching countermeasures.The third chapter explains the research design and research methods.The fourth chapter focuses on the analysis of the research results and attributes the mistakes.The fifth chapter puts forward the effective teaching countermeasure of rational number according to the typical error analysis.The results of this study can not only help math teachers better understand the typical mistakes and reasons of students in the learning process of rational number,but also provide certain teaching suggestions for the teaching of rational numbers,so as to improve the learning effect of students. |
