A Comparative Study Of The Old And New Textbooks Based On The 2017 Version Of The Curriculum Standard Of The People's Education A Version

With the continuous development and change of the society,the reform of mathematics curriculum in China has been in full swing.Since the publication of the mathematics curriculum standards(experiment)in ordinary senior high schools(experiment edition)in 2003,it has guided the education and teaching work for decades.During this period,there are also teaching guidelines,such as the revision of curriculum standards,but all of them are specified based on the current curriculum standards and educational concepts.The 2017 edition of mathematics curriculum standards for ordinary senior high schools(2017 edition for short)is a program teaching document that conforms to China's actual situation and has an international perspective,which lasted for four years after the ministry of education started the revision of ordinary senior high school curriculum in 2013 New curriculum standard after release,new textbooks published in 2019,in order to timely grasp the high school mathematics textbook of new changes,this paper to the people's education teaching club "the ordinary high school curriculum standard experiment textbook mathematics compulsory 3 A version,and the second volume of ordinary high school mathematics textbook required A version of the two versions,this paper compares and analyzes the experimental class standard and 2017 edition standard probability contents in the corresponding teaching materials under the compulsory part has carried on the comparative study.The first chapter of this paper mainly introduces the research background and significance;the second chapter literature review introduces the domestic and foreign research status of textbook comparison;the third chapter is the main research process and research methods of this question,including research object,research questions,research tools and related concept definition;the fourth chapter is about the general high school mathematics curriculum standard(Experiment)and general high school mathematics curriculum standard(Experiment)The compulsory part of probability in senior high school mathematics curriculum standard(2017 Edition)is compared from five aspects,and the changes of the two editions of curriculum standard in probability part are analyzed;the fifth chapter and the sixth chapter are the comparison of the probability part of experiment textbook mathematics compulsory 3 and the second volume of compulsory Mathematics in senior high school;the seventh chapter is the research conclusion and conclusion of this paper Suggestion.The main problems of this paper are as follows:1.What changes have been made to the compulsory contents of probability in the 2017 version of course standard?And try to analyze the reasons for the changes.2.What are the changes in the content of the two editions from a macro perspective?Based on the change of curriculum standards,the consistency is analyzed.3.From A microscopic perspective,this paper compares the examples and exercises in the new and old version of personal education A,systematically analyzes and summarizes the reasons for the changes,and attempts to put forward the problems that teachers should pay attention to when teaching.Through the research,it is found that the changes of curriculum standard in probability part are as follows:1.There are changes in curriculum breadth,curriculum depth and credit setting,but little change;2.The content requirements have changed a lot,and knowledge points have been added or deleted;3.The teaching tips of the 2017 curriculum standard are more specific,and clear guidance methods are proposed.At the same time,new academic requirements are added to guide teaching;Based on the requirements of curriculum standards,the following conclusions are drawn from the study of teaching materials:1.The changes of the new textbook column are mainly in the content,the type and quantity are basically the same as the old textbook,a new induction column is added,and there are many changes in the summary at the end of the chapter;2.The setting of examples has both inheritance and innovation.The change is reflected in the quantity and difficulty,the quantity is almost twice as much as the old textbook,and the comprehensive difficulty is more balanced.The design of example questions is more human-oriented,more in line with social life,and appropriately increase the knowledge content of the questions to make the investigation points of each question more comprehensive.3.The change proportion of exercises should be more.Firstly,the types of exercises are more abundant,and judgment questions and proof questions are set in the probability part.Secondly,in terms of comprehensive difficulty,except that the operation level is lower than the old textbook,the other four levels are higher than the old textbook.The distribution of mathematical cognition level is more balanced.Finally,the setting of exercises is more focused on the investigation direction of key exercises,which has a comparison Strong pertinence.
