Research On Developing Senior High School Students' Biological Key Competency Based On Dialectical Materialism Philosophy

The outline of basic education curriculum reform and the outline of the national medium and long term education reform and development plan all mention that moral education should be infiltrated into all links of teaching to form a correct world outlook,outlook on life and values.With the promulgation of the biology curriculum standard for senior high schools(2017 Edition),the development of students' biological key competency has become the top priority of biology teaching.Dialectical materialism philosophy is a scientific world outlook that combines materialism and dialectics.The use of dialectical materialism to look at and analyze biological problems is conducive to the development of biological key competency.In this paper,a senior high school biology teacher in Wuhai City is taken as the research object by using the method of questionnaire to investigate and analyze the situation of integrating dialectical materialism philosophy into senior high school biology teaching;Using the textbook analysis method,taking the compulsory 1 molecules and cells,compulsory 2 genetics and evolution,selective compulsory 1 steady state and regulation,selective compulsory 2 biology and environment,and selective compulsory 3biotechnology and engineering of Biology(2019 Edition)published by the people's education press as examples,this paper combs the contents of dialectical materialism philosophy contained in the textbook,The relationship between dialectical materialism philosophy and senior high school students' biological key competency is analyzed;According to the requirements of the biology curriculum standard for senior high schools(2017 Edition),the teaching design of developing senior high school students' biological key competency based on the philosophy of dialectical materialism is carried out,and the teaching principles are put forward.The results are as follows:(1)the teachers' survey results show that the vast majority of senior high school biology teachers do not know much about the philosophy of dialectical materialism,which is on the surface,without systematic learning,and do not have a deep understanding of the relationship between dialectical materialism and biology.(2)Combing the contents of dialectical materialism philosophy and high school biology textbooks shows that both high school biology compulsory textbooks and selective compulsory textbooks contain rich dialectical materialism thoughts,which is the content basis for developing senior high school students' biological key competency based on dialectical materialism philosophy.(3)Through the relationship between dialectical materialism philosophy and senior high school students' biological key competency,we can see that materialism can help students to establish the concept of material,stability and balance;The view of universal connection can help students to establish the view of structure and function,the view of steady state and balance,and enhance their social responsibility;The law of unity of opposites can effectively help students grasp contradictions,analyze problems,strengthen the understanding of core concepts,establish corresponding life concepts,and enhance scientific thinking;The law of quality alternation helps students design experimental gradients,analyze the use of dose,improve scientific inquiry ability,form good living habits,and establish a sense of social responsibility to protect the environment;Epistemology can better help students understand the history of biological science,cultivate the scientific spirit of continuous practice and research,develop critical and creative scientific thinking,and improve their scientific inquiry ability.(4)Through the teaching design of dialectical materialism philosophy to develop senior high school students' biological key competency,we carry out theme teaching based on materialism,analyze the materials and movement modes in cells,and help students establish the material concept;The knowledge system of internal environment and steady state is established by using the concept of connection,the concept of steady state and balance is established,and inductive scientific thinking is formed;Using the universality and particularity of contradiction to carry out debate teaching,establish the concept of structure and function,and form critical thinking;Looking at the relationship between people and environment from the law of quality alternation,helping students enhance their sense of social responsibility;Study the history of biological science from the perspective of epistemology,promote students to realize that biological research is inseparable from scientific practice,and enhance their awareness of scientific inquiry.The principle of permeability,selectivity and interest should be followed in the development of senior high school students' biological key competency with the philosophy of dialectical materialism.
