Study On The Connection Of Junior High School Teaching Under The 2017 Edition Of Chemistry Curriculum Standards

The Ordinary High School Chemistry Curriculum Standard(2017 Edition)describes the general high school chemistry course as a basic education course in which compulsory education chemistry or science courses are linked.Prior to this,the 2013 edition of the "General High School Chemistry Curriculum Standards(Experimental Edition)" also emphasized that the chemistry teachers in the high school stage should pay attention to the connection with the junior high school chemistry curriculum content in the process of starting the classroom teaching.The chemistry teaching in the junior high school and high school constitutes the whole chemistry teaching in middle school.Therefore,the two are always the main body that can not be ignored in the middle school chemistry teaching.Due to the continuous advancement of the curriculum reform process and the change of the subject textbook,the two are teaching.Contradictions in convergence are gradually being highlighted.In the content of the new curriculum standard,the requirements for chemical knowledge were updated,and the boundaries of some chemical concepts were also newly delineated.For students who have just entered the high school stage,due to their own knowledge accumulation and limitations of thinking characteristics,it is generally difficult to master the concept of chemistry.The redox reaction is one of the most basic concepts and is infiltrated into the high school chemistry curriculum,so it is critical to have a clear understanding of it.Students must produce an accurate,clear,and complete impression of their ability to establish a prerequisite for follow-up learning and improve their ability to handle chemical problems.In the first-grade chemistry teaching work in the high school stage,the redox reaction is a key content with greater difficulty.In the new curriculum standard,higher academic requirements standards are proposed for the content,which further increases the difficulty of teaching.After conducting a practical survey,the authors found that a large proportion of the students who have just entered the high school stage have a tendency to reduce their chemistry scores,and it is difficult to adapt to the high school life.Some of them even lost their chemistry.confidence.The main reason for this situation is the difference in teaching and learning in the junior high school and high school chemistry.Therefore,how to achieve the connection between the chemical concepts in the junior high school and high school is a very urgent and difficult problem.The successful completion of the teaching linkage study of the redox reaction in the junior high school and high school stage not only has a positive effect on students' mastery of chemical knowledge in the later stage,but also has a positive significance for the smooth transition from the enlightenment education to the basic science education.This thesis uses research methods such as interviews and questionnaires based on the theory of recent development zones.The research found that the problems leading to poor teaching in middle and high schools have the following points:First,the junior high school curriculum is inconsistent with the objectives of the course and the academic requirements for redox reactions;Second,the junior high school textbook has the problem of the fault of the knowledge point and the blind spot of the connection;Third,students are aware of structural defects,limitations in physical and mental development,and incorrect learning methods;Fourth,the problem of teachers' backward teaching concepts and single teaching methods.In view of the above problems,the author believes that to solve the problem of the teaching connection of redox reaction in the middle and high schools,the chemistry teachers in the third grade should change their minds to establish the previous teaching concept,and help students develop good learning habits while learning the basic knowledge;According to the theory of learning transfer,teachers should pay attention to guiding students to understand the connotation and extension of the concept of redox reaction from the perspective of logic.It can help students to understand the relationship between the concepts of self-learning and help students build knowledge networks and improve the structure of knowledge.Degree;high school chemistry teachers prepare for convergence in advance and choose a reasonable way to teach.
