Teaching Design And Practice Of High School Chemistry Review Course Under Reverse Teaching Idea

With the progress of society,there is an increasing demand for chemistry teachers to carry out efficient chemistry classroom teaching.As one of the important classes,review class is of great significance for students to consolidate old knowledge and develop new knowledge,and realize the transfer and application of subject knowledge.Through consulting a large number of literatures and materials,the author found that the reverse teaching design is similar to the suggestion of "student-oriented" situational teaching and focusing on the implementation of process evaluation for students put forward in the "Chemistry Curriculum Standards for General Senior High School(2017)Edition".Passes to the backward teaching design fully understand it is concluded that the concept is a kind of pursuit of understanding and evaluation of the teaching idea of priority,this paper proposes a design with conventional teaching to buck the teaching of logic,starting from the teaching goal to guide the design of the teaching evaluation and activity,design evaluation before the activity,both tightly around teaching target,Advocate the combination of various evaluation methods and the evaluation throughout the teaching to measure whether the teaching activities reach the teaching standards.It is suggested that teachers should fully analyze students’ learning situation,choose different teaching strategies and ways to carry out teaching activities according to the actual situation,and realize students’ understanding and transfer of knowledge in the real situation.This kind of teaching mode and chemical recitation teaching objectives as a whole together,found between the two there is a certain role in promoting,so the main research content of this paper is how to use the reverse teaching idea guiding chemistry teaching design and practice of recitation,promote students’ understanding of subject knowledge and the migration application,achieve high efficiency of chemistry review classroom teaching.The specific content of the research mainly includes the following points:1.Through the literature,the backward teaching design theory basis,elaborates the connotation and features,summarize and analyze the domestic and foreign chemical recitation,reverse research present situation and the trend of teaching design,it is concluded that the idea in the application of recitation teaching research is relatively small,applied to chemical recitation where there is little guidance in the teaching design and practice of research.2.Chemical recitation by teachers and students teaching and learning situation questionnaire,understand the current chemical recitation teaching present situation,find out the shortage of the application of reverse design in the chemistry teaching recitation put forward the corresponding teaching strategies,and design for chemical review wingsley type reverse teaching design pattern.3.Selecting the teaching material content,selecting the reverse teaching content of the chemistry review course,comprehensively analyzing the teaching material,course standard,exam outline and students’ learning situation,strictly following the reverse teaching process to carry out the teaching design of the Periodic Law of the Elements and improve it and carry out teaching practice.4.After the practice teaching practice of data collection,interviews with teachers and students,receives the feedback of teaching information,sorting and summary the practice as a result,through the analysis found that the reverse teaching idea guiding chemical recitation teaching to improve students’ learning initiative has a promoting effect,can help students to realize the real understanding of knowledge and skills of skilled,Effectively cultivate students’ comprehensive thinking and ability.5.This paper summarizes and analyzes the problems existing in the practice of reverse teaching design in the chemistry review class,and through personal reflection and summarizing the suggestions of front-line teachers,puts forward constructive suggestions to promote the reverse teaching concept and better guide the chemistry review class,in order to provide reference for the front-line high school teachers to carry out the chemistry review class teaching.
