A Study Of Design Of Structured Teaching Unit Based On Core Literacy Of Chemistry In Senior High School

With the promulgation of the new curriculum standards for ordinary senior high schools in 2017,a new round of curriculum reform has begun.Cultivation of students' core literacy has become the focus of teaching in various disciplines.How to cultivate students' core quality and innovative ability through classroom teaching has become a hot topic in the research of curriculum reform.The structured teaching unit design is an important carrier to implement the core literacy of the subject.After a lot of theoretical research and analysis,this study has explored the research on the structured teaching unit design based on the core literacy of the senior high school chemistry subject.It is of great significance to enrich the theory and practical curriculum reform and at the same time,it can provide reference models and teaching cases of design unit teaching for unit-line teachers.First of all,through a large number of literature surveys to understand the current research status of the relevant content of the subject,the concept of structured teaching unit design was defined based on the core literacy of chemistry as an entry point.Then the questionnaire about the situation of the unit teaching based on the subject core literacy was investigated and analyzed for 121 the chemistry teachers in the Zhangjiakou senior Middle School.By studying the construction method and design ideas of the structured teaching unit of the references based on the core literacy of the chemistry subject,and the specific design steps were work out.Based on this,some content of the chemical basic concepts and the element compounds are selected for the two case design.the unit teaching for the theme of "quantity of matter" was designed and practiced.In the process,it was implemented in the classroom,and comprehensive evaluation was performed,with good results.This topic main research results are: 1.Through the analysis and summary of online and offline questionnaire survey,to understand The proportion of key teachers from various schools participating in the survey who have a clear understanding of unit teaching is not very high,used less frequently,lack of effective operation guidance and reference examples in teaching design.2.Through preliminary theoretical research and the results of questionnaire analysis,the specific operational steps of the structural teaching unit design based on the coreaccomplishment of chemistry discipline were explored,unit teaching design that can be used for various teaching contents.3.Design case implementation works well,high student participation in the classroom,knowledge acquisition has been tested well,promotional value and feasibility.
