The Application Research Of Model—Construction Teaching Of Biology In Senior High School

"Lifelong learning,innovative thinking" is the demand for talents in the development of modern society.The curriculum standard of biology for senior high school(2017 Edition)has condensed the core quality of the discipline,and the "scientific thinking" in the core quality contains the content of innovative thinking,which requires us to pay attention to the cultivating of students' scientific thinking and innovative spirit in the teaching process.However,in the practical teaching,the way of learning biology is single and rigid,the ability of students' independent learning is weak,and the learning method is unscientific,so it is difficult for students to really improve their scientific thinking and innovation spirit.Especially when learning the content of the "Heredity and evolution" module of the human education edition,the ability requirements of students are relatively high.And the model-construction can help students to build a concept system on the basis of understanding,to make abstract knowledge specific,and to present the micro and difficult principle with models,which makes students can better understand the nature of biology and how to learn this part scientifically.And to a certain extent,it can cultivate students' innovative thinking,improve students' learning ability,and improve students' interest in learning.After consulting a large number of literature,this paper summarizes the theory and method of model-construction,the application of model-construction in teaching and the application in biology teaching.Through the students' questionnaire survey and teachers' interview to understand the current situation,find out the problems,put forward strategies,and apply the model-construction to their own teaching.In the process of application,Firstly,excavate the content of model-construction in the course standard and teaching materials,consult the relevant teaching design and teaching video,consult the experienced old teachers,carry out the teaching design and constantly improve it.Secondly,it explains the content of the model-construction method to the students and makes them fully understand it.Finally,in the process of teaching,the teaching concept of model-construction is permeated,and the teaching method of model-construction is applied.The specific operation is divided into building model in the new teaching and applying the model to teaching;building concept model after classto consolidate relevant content and knowledge;rebuilding relevant model in review class to summarize relevant knowledge and rules.It aims at the content of "the first two chapters of people education compulsory 2".After the application research,the individual students were interviewed.Through sorting out of the interviews,the observation of the students and the analysis of the case studies.Through the effect analysis,the author found that the model-construction could not only improve the students' interest in learning biology,enhance their ability to learn,to express and to communicate,exercise their practical operation ability and develop their scientific thinking,but also effectively promote the progress of students' achievement,change students' learning attitude,improve students' learning enthusiasm and enhance students' self-confidence.It can also enhance the communication between students and promote the establishment of friendship.It can also promote the development of teachers' professional growth,improve teachers' modeling thinking and modeling ability.
