Research On The Application Of Stratified Teaching In Chemistry Teaching Of Rural Junior High School Under The Background Of Double Reduction

In 2021,the "double reduction" policy issued by the state pointed out: "To implement the fundamental task of cultivating virtues and cultivating people,focus on building a high-quality education system,and strengthen the role of school education as the main front." Its spirit essence is to improve quality and reduce burden.Therefore,the traditional give-and-receive teaching method,unified assignment design,summarized teaching evaluation and other problems make the teaching at an important node of transformation.The new chemistry curriculum standard for compulsory education in 2022 clearly points out that teachers should comprehensively use a variety of teaching methods to promote students’ active participation,hands-on practice and cooperative exploration.The promulgation of the new curriculum standard makes the teaching target to cultivate students’ independent learning ability and innovation ability.With the implementation of the double reduction policy and the promulgation of the new curriculum standards,the rural junior middle school education has ushered in new challenges and opportunities.Under the new situation,the current situation of chemistry teaching in rural junior middle schools is generally not optimistic,mainly due to the insufficient investment in rural compulsory education,weak teachers,some teachers’ traditional backward teaching methods,which have seriously affected students’ interest in chemistry learning.Stratified teaching can organize teaching according to students’ different needs,interests and abilities to realize personalized teaching.This teaching method can not only improve students’ grades,lay a good foundation for cultivating students’ scientific literacy and practical ability,but also help teachers change teaching concepts and better adapt to the requirements of the new curriculum standards.Therefore,on the basis of reading papers related to stratified teaching,this paper combines stratified teaching with the current situation of rural chemistry teaching,and carries out a research on the application of stratified teaching in rural junior middle school chemistry teaching under the background of double reduction.There are seven chapters in this paper.The first chapter expounds the research background,significance,methods and contents.The second chapter combs the reference literature and finds that there are few researches on the application of stratified teaching in the chemistry teaching of rural junior middle schools under the background of double reduction.The third chapter is based on the core concepts,from the theoretical knowledge,to provide theoretical support for the implementation of hierarchical teaching mode;The fourth chapter investigates and analyzes the present situation of chemistry teaching in rural middle schools and concludes that the present situation of chemistry teaching in rural middle schools is not optimistic.The fifth chapter introduces the principle and process of the implementation of stratified teaching,and illustrates the concrete implementation process of "stratified teaching" with two teaching examples.In Chapter 6,after the completion of the experiment,questionnaire survey was conducted again to collect and sort out the obtained data,and the influence of stratified teaching mode on chemistry teaching was analyzed from the two aspects of questionnaire survey results and students’ performance before and after the experiment implementation.Chapter 7 is the conclusion and prospect of this research.After applying stratified teaching mode to chemistry teaching,the following conclusions are drawn through comparative analysis of data:(1)Stratified teaching can stimulate students’ interest in learning,correct students’ learning attitude,optimize students’ learning strategies,improve the academic performance of all students,narrow the achievement differences among students,improve the problem of student polarization,and promote students’ personalized learning to a certain extent.(2)Stratified teaching can improve teachers’ teaching efficiency.The application of stratified teaching mode is conducive to the implementation of the double-reduction policy and the "maximization" of students’ learning efficiency,thus ensuring students’ learning efficiency and alleviating students’ heavy homework after class,which is conducive to the implementation of the double-reduction policy.At the end of the paper,the author reflects on this research and suggests the direction of future research.
