Investigation And Practical Research On The Life-Based Teaching Of Biology In Senior High School

"General High School Biology Curriculum Standards(2017 Edition)" advocates the core literacy as the purpose,focusing on students adapting to the needs of future social development and personal life,fully reflecting the characteristics of biological disciplines and educating values,which puts forward the teaching of biology Higher requirements.Only when teaching really returns to life,can core literacy take root.Living teaching conforms to the needs of curriculum reform,based on the knowledge of biology and students' life logic,inspires students' interest in learning,and cultivates students' ability to participate in public affairs in the future,which is of great significance in practical teaching.Based on a large amount of literature research on life-oriented teaching,this paper investigates the current situation of life-oriented teaching of first-line biology teachers and high school students using survey methods and interviews.The setting is not in place;(2)The design of the content of the living teaching is unreasonable;(3)The material resources of the living teaching are insufficient;(4)The evaluation of the living teaching is unbalanced.Combined with interviews with some teachers,and then summarize the problems existing in life-oriented teaching,and analyze the causes of the problems from the internal and external factors,and finally put forward suggestions for life-oriented teaching according to the problems and reasons:(1)Reasonably set up life-oriented teaching Objectives;(2)Design life-oriented teaching content attentively;(3)Establish life-oriented teaching material library;(4)Improve lifeoriented teaching evaluation system;Then use your own teaching experience to carry out life-oriented teaching design on part of high school biology to The main undertakerprotein "is taken as an example of daily classroom teaching;the case of" detecting sugars,fats,and proteins in biological tissues "is taken as an example of improved experimental teaching of daily life,and it is put into practice by using educational internship opportunities Going by comparing the results of the pre-test and post-test of the experimental class and the control class,it is concluded that the life-oriented teaching has a significant improvement effect on students' learning interest,enthusiasm and self-confidence.This paper summarizes the high school biology life teaching from theory to practice,and has certain reference significance for the development of first-line high school biology teaching,improvement of life teaching and development of biology school-based curriculum.
