Research On The Teaching Design Of Junior High School Biology Unit Based On The View Of Structure And Functio

In the 2020 Revision of General High School Biology Curriculum Standards(2017 edition)2020 Revision,it is proposed to develop students 'core literacy of biology.Junior high school biology is in the same line,and the development of students' core literacy should also be taken as the fundamental task of the curriculum.Through the joint verification of practice and theoretical research,the unit teaching design is a sharp blade to conform to the "literacy era" of education and teaching,which can effectively improve the cultivation of students' core literacy in teaching practice.To sum up,considering the rich connotation of "life concept",the author selected the "structure and function concept" in "life concept" as the research object,design the unit teaching design mode and case based on "structure and function concept",and provide methods and paths for the teaching practice based on core literacy.First of all,the author uses the literature research method to summarize and analyze the research status of the teaching design,structure and functional view of the unit teaching at home and abroad,and determines the relevant concepts and connotations.Then,the author through the interview method based on the structure and function of junior middle school biology unit teaching design situation of the investigation,found that the lack of junior middle school biology teaching of structure and function of the core literacy systematic culture,frontline teachers lack of understanding of unit teaching design,the application is more obstacles,Suggestions to solve the problems found.And combined with the analysis of excellent unit teaching design case and "ADDIE" teaching mode,summarizes the excellent unit teaching design characteristics and unit teaching design elements,build to determine the unit theme and content,determine the learning objectives,unit learning plan,evaluation of the main line based on the structure and function of junior high school biology unit teaching design mode.Finally,this model was applied to the biology textbook of Jiangsu School,and the unit teaching case design with the theme of "structure level of organisms" was completed.This research is dedicated to the unit teaching design in the core literacy of junior middle school biology teaching practice application,build the "structure and function" of junior middle school biology unit teaching design mode,based on the pattern of a detailed unit teaching case design,hope to provide reference case for frontline teachers teaching practice,help frontline teachers improve systematic cultivation of students structure and function in practice.
