A Comparative Study Of The New And Old Textbook "Preliminary Solid Geometry" In The B Edition Of The People's Education

With the development of The Times and the progress of science and technology,a large number of scientific and technological talents are needed,and in order to cultivate these new generation of scientific and technological talents,mathematics curriculum has been constantly reformed.In mathematics teaching material of 2017 years ago have been to the "ordinary high school mathematics curriculum standard(experiment" as a benchmark for editing,launched the "ordinary high school mathematics curriculum standard(2017 edition",has carried on the various changes to the previous experimental draft,have also become more human mathematics curriculum of basic idea,pay more attention to strengthen moral education and cultivate people and other issues,at the same time pay more attention to course content and the fusion of science literacy accomplishment,in order to more comprehensive understanding of the teaching material "style geometric changes in what aspects has carried on the preliminary",in this paper,the broken and old study is carried out by comparing the two versions.This paper takes the preliminary contents of solid geometry in the new and 1-day version B textbooks as the research object,mainly USES the comparative analysis method to carry out the comparative analysis on the column day setting,writing style and knowledge points of the two editions of textbooks,so as to reflect the differences between the two editions of textbooks and discover the intention of textbook changes.Through comparison,it is found that the logic of the new edition of textbooks is more rigorous and more consistent with the law of students' cognition and more systematic.In terms of column setting,there are differences between the old and the new editions of the textbooks.The new textbooks pay more attention to the development of students' core literacy and combine core literacy with mathematical knowledge more closely.The newtextbooks pay more attention to the introduction of knowledge,and it is easier to improve the participation of students by asking various questions to create mathematical scenarios.The old textbooks lay more stress on the imparting of knowledge points,while the new textbooks lay more emphasis on letting students discover and summarize independently,pay more attention to the accumulation of students' experience in mathematical activities,and pay more attention to the integration of information technology and mathematics.It is found that the difficulty of the new edition is obviously higher than that of the old edition.Through the summary of the textbook changes,on the one hand,I hope to help the future textbook writing,on the other hand,I hope to better use of the textbook for teachers to play a certain role of Suggestions.
