Research On The Predicament And Countermeasures Of The Connection Between Junior And Senior High School Chemistry Concept Teaching Under The Background Of The New College Entrance Examination

A new round of reform of college entrance examination,high class of 2021 students in Chong qing will adopt a “3+1+2”model of college entrance examination.Under the vision of new college entrance examination and new curriculum standard,new requirements have been put forward to teachers' teaching,and the training objectives of students have also been changed.Chemistry teaching pays more attention to the concept of chemistry which is the key and difficult point in junior and senior high school chemistry teaching.The author hopes to find out the dilemma of chemistry concept teaching cohesion in junior and senior high schools and put forward relevant countermeasures.Therefore,it is hoped to enhance teachers' awareness of cohesion and make chemistry teachers pay more attention to the cohesion of chemistry concept teaching.To improve the teaching effect,teaching quality,but also further promote the professional development of teachers.It has some help to the study of biochemistry in junior and senior high school,improve its learning effect,enhance its interest and confidence in chemistry learning,overcome difficulties,and promote the cultivation of students' ability and the development of students.The author through a large number of literature,on the basis of predecessors' research,the concept of high school chemistry teaching material analysis,to implement the questionnaire survey and interviews,according to the result of investigation and interviews,analysis of the concept of high school chemistry teaching in chemistry course is more difficult,students' own learning habit is bad,backward teacher education teaching idea,teacher cohesion consciousness is not enough these difficulties.Based on this,the following countermeasures are proposed:(1)High school textbooks and junior high school textbooks should be structural,systematic and integrated,and present the concept of chemistry in detail.Middle and senior high school textbooks should be more closely linked and better connected.(2)Junior and senior high school chemistry teachers should constantly update their ideas.(3)Junior and senior high school chemistry teachers should adopt appropriate teaching methods.(4)Teachers should guide students to learn chemical concepts correctly.(5)Teachers should pay more attention to the cohesive teaching of chemistry concepts in junior and senior high schools.(6)Students should master good methods of learning chemical concepts.(7)Students should form a good habit of learning chemical concepts.(8)Students should increase their interest in chemistry.Through case implementation and result feedback,the learning habits and methods of chemical concept learning of more students in the implementation class have been improved to a large extent,and students' interest and confidence in learning chemistry have been enhanced as well as the learning effect,which also has some positive effects on students' choice of chemistry subject.It is of some help to the connection of chemistry concept teaching in junior and senior high schools.Teachers have a deeper understanding of the concepts of the new curriculum standard and textbooks,and set up a sense of connection to some extent.Besides,they have more experience in chemistry concept teaching,and their professional level and teachers' education and teaching level have also been greatly improved.
