Construction And Practice Of Biology "3+3" Teaching Mode

In 2018,the Ministry of Education promulgated the "General High School Biology Curriculum Standards(2017 Edition)",which clearly pointed out that the biology curriculum should be aimed at improving the core literacy of students’ biology[1],and also pointed out that "pay attention to students’ background in real life Understand biology.Biology courses in our country are developing in a new direction,which not only makes the content of the course closely related to life and the times,but also "emphasizes practice" in the teaching process.The author systematically analyzed the current research status in the field of biological life-oriented teaching through the literature research method,guided by Dewey’s life education theory,OBE education philosophy,and constructivist learning theory,and proposed biology that is suitable for the high school biology textbook of the People’s Education Edition.+3" teaching mode,discussing the formulation of teaching objectives,overall teaching procedures and operating procedures,implementation principles,evaluation content and methods,etc.The author applies the "3+3" life-oriented teaching model to practice,designing the content of Chapters 2,4,5,and 6 of Compulsory Biology 1,and setting up experimental classes and control classes for teaching practice research.In testing the teaching effect,the author adopts the questionnaire survey method,the performance analysis method and the interview method.The survey results show that the "3+3" teaching model of biology uses the life-oriented problem situations and practical tasks in the tutorial case to point out the learning path for students,let students generate life experience,conduct cooperative exploration,and be oriented to solve real life problems.,Make reasonable inferences and deductions,obtain scientific knowledge through the instruction of classroom teachers,and further apply what they have learned under the guidance of teachers after class,thus improving the core literacy of students to a certain extent.In terms of academic performance,it improves students’ cognitive drive for learning,and the teaching process conforms to students’ cognitive laws,which is enlightening and staged,so it also has a certain positive impact.This study has shortcomings,short practice time,and does not show significant results in terms of academic performance.The "3+3" teaching model of biology is intended to change students’ learning styles and affect students’ daily behaviors,and requires long-term training.Therefore,at the end of the article,the author puts forward suggestions for the implementation of the existing problems in the research.In general,this teaching mode can give full play to the subjective initiative of students,and allow students to explore learning through cooperative organizational forms driven by interest,effectively implement the cultivation of biological core literacy,and complete academic tasks.This research can It provides reference for the life-oriented teaching of frontline teachers,and also provides direction for the future life-oriented teaching research.
