A Comparative Study Of "corners" In Primary School Mathematics Textbooks Published By People's Education Edition, Jiangsu Education Edition, And Shanghai Education Edition

Textbooks,which are compiled by mathematics curriculum standard,are important resources of achieving curriculum targets and actualizing classroom teaching.Study effect is directly dependent on rationality of textbook.Currently,there are more than six textbooks of primary textbooks which are compiled and identified by mathematics curriculum standard in 2011.Among them,the textbooks published by the People’s Education Press have the most users.Textbooks published by Jiangsu phoenix Education Press are mainly used in Jiangsu Province,and widely used in whole country.The Shanghai Municipal Education Commission independently issued the Shanghai curriculum standards in 2004 and prepared relevant materials.Elementary schools in the UK are learning the advanced concepts of Shanghai mathematics textbooks from 2017.It can be inferred that Textbooks published by Shanghai Education Press have much international influence,The study selects textbooks materials of angle as a object of study,using document analysis and interview,connecting research approaches qualitatively and quantitatively.It is aimed at making comparative studies on these three textbooks from four parts including compiling system,substance,stimuli-presenting mode and exercises.Apart from this,it will try concluding similarities and differences about three editions of textbooks and find characteristics of different textbooks.The study will play an important roe in compiling primary school mathematics textbooks and practical school teaching.It is included that three editions of textbooks are all divided into two terms so as to learn angle separately.Relative mathematical thinking methods are all being utilized.Textbook published by Jiangsu phoenix Education Press has the second substance depth,interesting layouts with different presentations.It is inclined to using moving angles.It emphasizes practical application of angles,and angle cultural study.However,exercises don’t have high levels.Textbooks published by he People’s Education Press are able to connect with student’s life with the most difficult content and exercises.They also respect students in the main-body teaching and attach importance to student’s self-summary.Exercises are comprehensive with highly situation creations.Textbooks published by Shanghai Education Press have a tidy content,a simple layout and new materials with a sense of times.Examples focus on details a lot,but there is less exercises.The writer finds a few suggestions from comparative analysis and interviews:textbooks focus on multiple representation of mathematics knowledge to meet the needs of different students;material is both straight and easy to understand,but also pay attention to the scientific nature of the concept of expression;take note of exercises with different backgrounds and types,and reasonably control the difficulty of exercises;teaching substance absorb the latest scientific and technological achievements in time.Change in stability;textbooks should focus on operation and guide students to learn.
