Research On The Selection Of Teaching Content For Chinese Popular Science Expository Writing In Junior High School Based On The Study Of Famous Teachers’ Lesson Examples

Expository style is one of the important styles selected for junior middle school chines teaching materials,and expository style teaching for popular science plays an important role in junior middle school teaching.With the advancement of the Chinese curriculum reform,the Chinese circle has paid more and more attention to the reform of teaching content.Previous researchers have studied and found some problems in expository writing teaching,For example,"the generalization,one-sided and repetition of teaching content,the difficulty of teaching teachers and students’ weariness of learning lead to low teaching efficiency.In response to these problems,researchers have actively explored the teaching strategies of expository writing,and achieved many theoretical achievements.Among them,the research results on the teaching content of popular science expository writing are relatively small,and more concentrated in the primary school stage.Even so,on how to choose appropriate teaching content,The view of "studying and judging the learning situation,based on the style,and based on the curriculum standard" has been recognized by most people,which has important theoretical significance for the teaching practice of first-line science expository text.However,there is still a big gap between theory and practice,and there is still a large space for research.Based on the study of the new Chinese curriculum standard(2022 edition),this paper studies the selection of appropriate teaching content for popular science expository writing,focusing on Unit 5 of the eighth grade Chinese textbook for junior high school students.Starting with the selection basis,this paper obtains experience and inspiration from studying the classroom records of famous teachers,attempts to determine the teaching content of this expository writing unit,and summarizes some feasible practical strategies.The paper mainly includes the following parts:The introduction part briefly summarizes the origin of the research,relevant research reviews and research issues.After defining relevant concepts,it briefly explains the research ideas and methods.The first chapter,starting from the theoretical level,studies the basis for the selection of teaching content of popular science expository texts,mainly including three aspects.First,the analysis of the selected expository texts in textbooks;Second,the guiding role of the new curriculum standard in the selection of expository writing teaching content;The third is the stylistic features of the expository texts of popular science.The second chapter is the practical research part,mainly through the analysis and comparison of the classroom teaching records of famous teachers,to study the classroom teaching content of famous teachers in Unit 5 of the first volume of the eighth grade Chinese textbook,so as to obtain some inspiration in the selection of teaching content,and to reflect and summarize this,to lay the groundwork for the next chapter to study the teaching content selection strategy of popular science expository text.The third chapter combines theory with practice,starting from the strategy,from the "unit teaching content selection of the overall strategy","single text teaching content selection strategy","students’ perspective of teaching content selection strategy" three aspects of analysis and explanation.Taking the fifth unit of the first volume of the eighth grade Chinese textbook as an example,from the theory to the practice,from the selection of ideas and methods,summed up some content points,in order to provide some valuable practical reference for the choice of teaching content of popular science narration.
