Research On The Teaching Design Of Junior High School Biology Unit Based On Ecological Perspectiv

With the rapid development of society,environmental pollution,resource depletion and other problems are increasingly serious.In order to solve the current environmental problems,the Third Plenary Session of the 18 th CPC Central Committee clearly proposed to build an ecological civilization society,which is an effective measure to realize the harmonious coexistence between man and nature.The middle school students are the future builders of our country and the bearers of the future environment.It is an important task and an obligation for every teacher to educate the middle school students about ecological civilization and make them develop good habits of ecological civilization.The Biology Curriculum Standards for Compulsory Education(2022 Edition)(hereinafter referred to as "Curriculum Standards")points out that it is necessary to focus on the development of core qualities of Chinese students and cultivate the correct values,essential qualities and key abilities of students to adapt to future development.The curriculum concept also emphasizes the purpose of core qualities.As a sharp edge of education and teaching conforming to the "era of core literacy",unit instructional design can just effectively implement the cultivation of students’ core literacy in teaching practice.Ecological civilization education for students can organically combine unit teaching design with ecological concept of life concept,which can not only help front-line teachers to better implement the cultivation of students’ core quality of biology,but also guide junior high school students to form good awareness and behavior habits of ecological civilization.It is of great significance to ecological progress,building a moderately prosperous society in all respects and building a beautiful China.Based on the research background and significance of ecological concept,this paper expounds the research background,defines related concepts and analyzes the research status of ecological concept and unit instructional design at home and abroad through literature research.Through a questionnaire survey of teachers in some areas of Liaoning Province,this paper aims to understand junior high school biology teachers’ understanding of core literacy,life concept and ecological concept of biology,and to understand the implementation of ecological concept education and unit teaching design and the obstacles in the implementation process.Combining with the analysis of high-quality unit teaching design cases and the existing "ADDIE" teaching model,this paper summarizes the elements and characteristics of excellent unit teaching design,and constructs a junior high school biology unit teaching design model based on ecological view.This model is applied to the unit teaching design of "Biology and environment" in the current junior high school biology textbook.This study is committed to building a teaching design model of junior high school biology unit based on ecological view,hoping to bring some inspiration to front-line teachers and better implement and develop students’ core biological literacy.
