Research On The Cohesion Of Mathematics Teaching In Junior And Senior High Schools

With the development of the new curriculum reform of elementary education,the problem of improper cohesion between junior and senior high schools in teaching is particularly prominent.There are great differences between junior and senior high school mathematics from the aspects of curriculum standards,teaching materials,teaching methods,learning methods and thinking ability.The unreasonable or even lack of teaching arrangements of the cohesive knowledge of mathematics in senior high schools is not conducive to the smooth transition of students,and directly affects the growth of students in senior high schools.For the first time,"Mathematics Curriculum Standards for Ordinary Senior High Schools(2017 Edition)" puts forward the preparatory knowledge of the curriculum as a theme,which reflects the importance attached to cohesive knowledge under the background of curriculum reform.This paper mainly studies the cohesion of mathematics teaching in junior and senior high schools from five parts.The first part briefly describes the background of the topic selection,analyzes the goal and significance of this topic,determines research ideas and new ideas,consults the literature and related theoretical knowledge needed by the research topic,sorts out the research status of cohesive knowledge,and formulates the directions and priorities of the research.The second part studies the current situation of the cohesion of mathematics teaching in junior and senior high schools,which is divided into three parts:(1)to survey students' cohesive knowledge between junior and senior high schools by questionnaires and explore their mathematics learning status in different periods from six dimensions: interest in mathematics learning,learning situation of junior high school cohesion knowledge,differences in mathematics learning between junior and senior high school,classroom cognition of senior high school mathematics,expectation of teachers' cohesive knowledge teaching and confusion in senior high school learning;(2)to design related mathematical exercises for eight cohesive knowledge points,and analyze senior one students' present mastery level of cohesive knowledge through the correct rate;(3)to get teachers' teaching process on cohesion problems by interviews.The third part explores the internal causes of improper convergence of mathematics knowledge in junior and senior high schools,and makes a differentiated research in four aspects: curriculum standards,teaching materials processing,teachers' teaching methods and students' academic conditions.The fourth part is to expand and extend,and design two typical connecting lessons,which reflect the transition and extension from junior high school knowledge to senior high school guided by the problem trend.Then,it expounds three changes in the textbook of A version of senior high school mathematics new curriculum standard: paying attention to core literacy,adjusting the order of knowledge chapters,optimizing the teaching content,and paying attention to the connecting content of junior high school mathematics under the new textbook.The fifth part puts forward teaching suggestions to teachers from three angles:(1)studying the curriculum standard,and closely following the teaching materials;(2)setting up bridging courses based on the specific circumstances;(3)implementing effective teaching: aiming at learning well,paying attention to students' development,selecting appropriate teaching strategies and forming teaching synergy.It is hoped that through this research,it can provide some reference for teachers in the optimization of cohesion between junior and senior high schools.
