Establishment And Practice Of Life Teaching Situation In High School Biology Teaching

The biology curriculum standards for senior high school(2017 Edition)advocating the core literacy oriented biological education and the biology curriculum concept of focusing on students' biological core literacy and paying attention to the connection with real life.But for a long time,the mechanical classroom that teachers speak and students listen to exists widely.This kind of teaching method cuts off the connection between knowledge and life,making the biology classroom teaching lack of vitality,and students' curiosity can't be fully satisfied.It is not only the requirement of the curriculum standard,but also in line with the concept of biology course to create life teaching situation and integrate life experience with book knowledge.In view of this,this study takes the high school biology "heredity and evolution" as an example to carry out the research and teaching practice of the creation of high school biology life teaching situation,in order to promote the high school biology teaching level and students' core literacy of biology.First of all,this paper introduces the research status of the creation of life situation at home and abroad in detail,and carries out questionnaire survey and interview on 149 students and 28 front-line biology teachers of Shawan No.1 Middle School in Xinjiang.The results show that 30% of the students think that the biology classroom is boring and out of touch with life.92% of the students welcome the creation of life situation class.They hope that teachers can adjust measures to local conditions and teach students in accordance with their aptitude in the design and implementation of creating life situation classroom.In biology class,we should pay more attention to the reality of life,create life situation,and make full use of teachers and students interaction;all the interviewed teachers think it is necessary to create a life-based teaching situation,but there aredifficulties and obstacles in the creation and practice of life-based teaching situation,and the application of the creation of life-based teaching situation in the actual teaching process is not ideal.Then,based on the theories of constructivism learning,situational cognition and learning,on the basis of carefully studying the curriculum standards and specific teaching materials,combined with the students' learning situation and their own teaching experience,this paper puts forward five basic principles that should be followed in the creation of high school biology life teaching situation,namely,the principle of goal,the principle of coherence,the principle of problem,the principle of science and the principle of openness.Furthermore,four ways of creating life-based teaching situation are proposed,namely,using modern technology to create life-based virtual teaching situation,using social life hot spots to create life-based exploration situation,paying attention to students' experience to create life-based cooperation and communication situation,and using life reality to create living practice situation(experiment and production).On this basis,this paper combs the knowledge points in high school biology compulsory II "genetics and evolution" which are in line with the creation of life teaching situation,and at the same time,it shows three life situation teaching cases and expounds its implementation strategies,which can provide reference for the follow-up teaching practice research.Finally,taking the students of top class(4)and strengthening class(12)as experimental group and top class(5)and strengthening class(18)as control group,a60-day practical research on high school biology life oriented situational teaching was carried out,and the results of teaching practice were compared by comparing the changes of students' learning performance,learning interest and subject core literacy analysis.The results show that the implementation of Life-based situational teaching can improve students' learning performance to a certain extent;it can effectively improve students' interest in learning,the classroom atmosphere is more active,and the students' participation in the classroom has been significantly improved;in the learning process,students not only grasp the essence,principles and research methods of biological science,but also improve their hands-on ability Finally,it develops the students' core quality of biology.In a word,this study preliminarily discusses the principles and methods of creating high school biological life teaching situation,and takes "Genetics and evolution" module as an example to carry out teaching practice research,and summarizes and reflects on theteaching practice effect,hoping to provide reference for senior high school teachers to carry out student activation situational teaching.
