Setting The Content And Evolution Research Of The Pythagorean Theorem On PEP Middle School Mathematics Textbooks Teaching

The Pythagorean theorem is one of the classic content in the middle school mathematics textbook,so the emphasis on writing the Pythagorean theorem in mathematical textbooks gradually increased,content arrangement is gradually optimized,through the knowledge of mathematical history,let students better grasp of mathematics thinking method,arouse students' interest in learning,cultivate the spirit of exploration,strengthen the influence of history.Written in the textbook is the main teaching syllabus(curriculum standards)for reference.On the basis of middle school mathematics teaching syllabus(curriculum standards)changes,the middle school mathematics textbook in People's Republic of China since the founding of the people's education publishing house,is divided into four stages to explain(not including the cultural Revolution),the middle school mathematics textbook people's Education Press published since 1949 to dibon,changes of the Pythagorean theorem set,the main research contents are as follows:First of all,the research purpose,significance,research status at home and abroad,research methods and innovationSecondly,the structure and arrangement of four stages introduced people to teach content version of the Pythagorean theorem in the middle school mathematics textbook,and analysis of the characteristics.At the same time also to the Pythagorean theorem and its historical contents arrangement changes,are analyzed in detail.Again,the Pythagorean theorem in textbook examples,exercises and exercises set were studied.Mainly from the overall structure,general requirements,quantity,type,compare the thought method,expounds the characteristics of its change.Finally,the changes of contents of the Pythagorean theorem are summed up,analyzed the advantages and disadvantages of arrangement of middle school mathematics textbook since 1949 and suggestions.
