Research On After-class Exercises Of The New High School Biology Textbook Based On Core Literacy

In 2018,the Ministry of Education promulgated the "General High School Biology Curriculum Standards(2017 edition)",setting "cultivating students' core literacy in biology" as the focus of high school biology courses.Subsequently,the compilation of the new version of the biology textbook began gradually.The writers not only improved the structure,columns and content of the textbook,but also upgraded the after-school exercises of the textbook.Therefore,it is necessary to analyze the characteristics of the after-school exercises in the new textbook from the perspective of the core literacy of biology.There are three reasons: First,it can provide first-line teachers with suggestions and references for using the exercises of the new textbook;second,it can provide teaching ideas for teachers to develop exercises based on the core literacy of biology;third,it can provide students with a large number of real and novel problem situations,so that they can test their own core literacy level,so as to effectively implement the requirements of high school biology curriculum standards.By sorting out and comparing related literature materials at home and abroad about exercises,exercises teaching,core literacy,and core literacy of biology,the theoretical basis and conceptual connotation of this research have been analyzed.In addition,based on the combination of the new textbook and the core literacy of the biology subject,through studying a large number of documents related to the textbook exercises,the teaching strategy based on the new textbook exercises as a foothold was analyzed and summarized,and some cases were selected for teaching.Design and analysis to help front-line teachers make better use of new textbooks and exercises.This research mainly conducts research from the following three aspects: First,select the Biology Compulsory Part 1: "Molecules and Cells" in the 2019 People's Education Edition General High School Textbook as the research object.From the perspective of the core literacy of the biology subject,the after-classes in the new textbook the column of exercises has been analyzed and sorted out to help teachers become familiar with a large number of exercises in the new textbook as soon as possible.Second,based on the characteristics of exercises,it analyzes the teaching strategies of implementing core literacy in teaching,and provides teaching ideas for teachers to develop exercises based on the core literacy of biology.The third is to help teachers choose appropriate teaching strategies based on the actual situation.Chose the "Exercise and Application" column in chapter 5,section 4,"Photosynthesis and Energy Conversion" in the new textbook compulsory 1,and the "Exercise and Application" column in chapter 5 " The "Review and Improvement" column in "Cell Energy Supply and Utilization" is a case of exercises teaching,hoping to put forward practical teaching suggestions for frontline teachers?The research results of this research can not only provide a certain theoretical reference for the after-school exercises of the new biology textbooks in our country,but also provide guidance for frontline teachers to use the exercises columns of the new textbooks,and have certain theoretical and practical significance.
