Research On Middle School Biology Teaching Model Based On System Theory

In recent years,as "biological science","biomedicine","gene editing" and other words frequently appear in People's Daily study and life,people's cognition of the field of biological science is gradually deepened.As an important channel for young people to acquire biological knowledge and master the necessary biological skills,biology course plays a more and more important role in middle school teaching system.Biology is both theoretical and practical.The promulgation and implementation of the "General Senior Middle School Biology Curriculum Standard(2017 Edition)" put forward higher requirements for implementing the core literacy training goals of middle school biology teaching.How to innovate the biology teaching model has become the focus of experts and teachers.At present,there are still some outstanding problems in the teaching of biology in middle schools,which restrict the progress of the new curriculum reform.The main manifestations are: First,the conservative teaching ideas of teachers,"hegemonism" and "arbitrariness" classroom teaching are still everywhere;Second,the ability of students to find and solve problems is seriously lacking,and the ability of autonomous learning,collaborative learning and knowledge integration is quite lacking;Thirdly,with the widespread application of digital technology in teaching,the tendency of "fragmentation" of knowledge becomes more and more serious,and students cannot get good systematic knowledge learning and thinking training.In response to the above outstanding issues,this article is guided by system theory,applies the research methods of literature research,investigation research,comparative research and case analysis to study the construction of the biology teaching mode in middle schools based on system theory.This paper comprehensively sorts out the origin,generation and development process of system theory,has a deep understanding of the ideological connotation of system theory,and defines the concept of system teaching mode by combining the teaching mode with the analysis of the application status of biology teaching mode in middle schools.Then,based on an in-depth analysis of the teaching attributes of biology courses in middle schools,this paper studies the applicability of the teaching model of system theory in biology teaching in middle schools,explores and constructs the teaching model of biology system in middle schools,and carries out teaching case design and teaching practice,so as to provide reference for the innovation of biology teaching model in middle schools.Through analysis,the system theory teaching mode in biology teaching in middle school has strong suitability,in the process of new curriculum reform unceasingly thorough propulsion,based on the theory of middle school biology teaching mode on teaching subsystem to rearrange the portfolio in order to maximize the teaching task goal,its application to break through the bottleneck of new curriculum reform in our country has the certain enlightenment function.System theory was formed based on the theoretical status of mechanization and control of scientific research at that time.With the change of the times,the connotation of system theory is becoming richer and richer.When applying the system theory,biology teachers in middle schools must combine the current educational practice and apply it critically.Must not copy,mechanical application of relevant theories.
