A Comparative Research Of The Circle Content In Third Phase Of Compulsory Education

For the development of basic education and curriculum reform,revision of compulsory education curriculum standards is an important task.In 2001,the Ministry of Education issued the "Mathematics Curriculum Standard(Experimental Draft)",after three revisions,then the Mathemati-cs Curriculum Standard(2011)was issued in 2011 finally,Based on it,mathematics textbooks are bound to be changed.Therefore,the article focus on the reform of circle in the curriculum standards,and compare of two different edition`s junior high school textbooks about the content of Circle,the People's Education Press and Beijing Normal University Press.From the perspective of "mathematics curriculum standards",on the hand,it is a comparative study of the "curriculum standard(2011 edition)" and "curriculum standard(experimental draft)".The curriculum concept of two "mathematics curriculum standards(2011 edition)" emphasis on the cultivation of mathematical thinking,while the course content is mainly not "graphics and geometry" as the mian content of the study,but also on the two "mathematics curriculum standards" in the "curriculumstandards".Besides,The number of behavioral verbs in the third semester is analyzed statistically.On the other hand,itisacomparativestudyofthe contentsofthetwomathcurriculumstandardsandthedifficulty of the round course: the circle content is divided into two parts,theelective and must learn.And in this article,the circle and the circle position relationisdeleted,as well as thedifficultyoftheroundcourse is increased.From the perspective of mathematics textbooks,the study analyzes and contrasts the presentation style,the arrangement order,the example exercisesof the two versions of the textbook and the edition of the two volumes of the Beijing Normal University Edition.The content of the in the teaching version is better than that of the Beijing Normal University edition,and the layout of the contents of the book reflects the continuity of the knowledge system and integrity.But the Beijing division version is more focused on hands-on operation and independent thinking of the training,the North Normal Edition spends a lot of time on the theorem of exploration to train the students ability on exploration and knowledge acquiring.
