Ways And Methods Of Cultivating The Concept Of Evolution And Adaptation In High School Biology Teaching

The Ministry of Education's 2018 document “General Senior High School Biology Curriculum Standard(2017 Edition)” points out that the basic concepts of biology teaching in senior high school are: core accomplishment as the purpose,content focusing on the big concept,teaching process emphasizing practice,teaching evaluation promoting development,and points out that the subject core accomplishment of biology is life concept,scientific thinking,scientific inquiry and social responsibility.Among them,the concept of life is the most able to reflect the characteristics of biology and educational value,the core of the concept of life is the concept of evolution and adaptation.The view of evolution and adaptation is the meridian and weft that run through all the biology contents of middle school and is the core idea of unifying biological knowledge system.by This shows the importance of cultivating students' view of evolution and adaptation.Based on the existing teaching research results,this research uses literature analysis,questionnaire survey,case analysis,on the basis of further analysis of the connotation of evolution and adaptation view,to investigate and analyze the current situation of biology teachers training students' evolution and adaptation view,find out the problems and propose countermeasures.In this study,the connotation of the concept of evolution and adaptation is further understood as follows: to promote students to form cognitive thoughts,consciousness and ideas of life with biological evolution and adaptation as the core through biology teaching.At present,biology teachers in senior high school are faced with the following problems: insufficient study on the contents of Curriculum Standard,further understanding of evolutionary theory,low attention to the progress of evolutionary theory research,and tight teaching time.The countermeasures are as follows: to strengthen the continuous learning of post-service teachers,to strengthen the development of sharing platform of teaching resources,and to promote theexploration of teaching evaluation system.In this study,the teaching approaches and methods to cultivate the concept of evolution and adaptation of high school students mainly include: excavating teaching materials,formulating reasonable teaching objectives and choosing targeted teaching strategies.When analyzing the contents of teaching materials,teachers should not only make clear and utilize the “explicit” knowledge that cultivates students' view of evolution and adaptation,but also excavate the available “tacit” knowledge.In the formulation of teaching objectives,teachers should combine the requirements of the Curriculum Standard,the content of teaching materials and the situation of students to formulate specific,achievable and measurable teaching objectives of evolution and adaptation.In terms of teaching strategies,the main strategies proposed in this study include: passing through the history of science,general Reading pictures,carrying out the second class,etc.,to help students form ideas of evolution and adaptation.In practical teaching,teachers can flexibly adopt various teaching strategies to achieve better results.
