Research On The Construction Of The Core Concepts Of High School Chemistry Under The Theory Of Learning Progression

At present,the best way for basic education to achieve results is to comprehensively pro mote quality education under the premise of combining with the new curriculum standards.Th rough the continuous practice and accumulation of the Ministry of Education,on May 13,2020,《the Chemistry Curriculum Standards for Ordinary Senior High Schools》(2017 Edition re vised in 2020)will be issued.The reform of the new curriculum standard means that the disad vantages of traditional teaching have been revealed,and the inculcated education is no longer in fashion.The new curriculum standard is proposed on the basis of the traditional threedimen sional objectives,requiring students to form the corresponding subject core quality while lear ning the knowledge of chemistry.The knowledge of chemistry is rather complicated and scatt ered.Therefore,teachers’ education focus is not only to let students understand the knowledge,but also to cultivate the ability of selfconstruction of students.Based on the background of learning progression theory,this paper studies the construction of chemistry core concepts of senior high school students by literature analysis,questionnaire survey,interview,experimental research and other experimental methods.In the preliminary preparation stage,the relevant literature was sorted and analyzed,and the research status of "advanced learning","core concepts" and other related contents was understood.Then the research literature on the core concepts of chemistry was sorted out,the research direction with "chemical balance" as the main body was determined,and its research status,learning value,knowledge structure and other aspects were further analyzed.Based on certain theoretical foundation,separately from the students’ interest in chemistry discipline,the degree of understanding of core concepts of high school chemistry,the chemistry of the construction of the core concepts of the degree of understanding,learn the advanced application in construction process of four aspects to design the questionnaire,the result analysis for chemistry students advanced understanding and application of the concept of the core is not very ideal;through the interview survey of teachers,the existing problems and applications in the actual teaching process are understood.Finally,using the experimental research method,two parallel classes with similar levels are selected to compare the advanced teaching around the core concept with the traditional teaching methods,so as to understand the practical application effect of the advanced teaching around the core concept of chemistry.Through the analysis of the results,the targeted training strategies are put forward from the perspectives of schools,teachers and students,and the teaching cases based on the advanced learning theory are designed accordingly.The conclusion of this study is: carrying out advanced learning research around the core concepts of chemistry can help teachers reasonably design advanced level,effectively complete teaching objectives,and play a good auxiliary role for students to learn important and difficult knowledge and master basic knowledge,so as to improve their academic performance and form corresponding subject literacy.
