Content Analysis And Case Design Of Environmental Education In Biology Textbooks Of Senior High School

With the advancement of science and technology,various human economic have developed rapidly,which has greatly improved the living standard of human beings,but it also brought a series of environmental problems,such as pollution of water and land resources,smog,desertification,sharp decline in biodiversity,and virus outbreaks,which exacerbated the contradiction between people and the natural environment.The party and the country attach great importance to the increasingly severe environmental problems.The 15 th National Congress of the Party put forward the "sustainable development strategy" for the first time;the 18 th National Congress regards "beautiful China" as the grand goal of ecological civilization construction,from the realization of the great rejuvenation and sustainability of the Chinese nation Starting from the overall situation of development,the construction of ecological civilization is included in the strategic height of the overall layout of a five-pronged approach to building socialism with Chinese characteristics.The high school stage is a critical period for the development of youth's outlook on life,world outlook and values.Students have strong plasticity and teacher-oriented,therefore,one of the effective ways to strengthen students' environmental education and develop environmental protection concepts is to implement environmental education for students.Biology course is one of the courses most closely related to environmental education,is the expansion and extension of compulsory education courses,plays an important role in improving students 'environmental literacy and cultivating students' sense of social responsibility.This article starts from the current research situation of environmental education and textbooks at home and abroad,uses STSE education theory and sustainable development theory,based on "Elementary and Middle School Environmental Education Implementation Guide(Trial)" and "General High School Biology Curriculum Standards(2017 Edition)",The relevant content of environmental education in the compulsory textbooks of high school biology is sorted out,analyzedand summarized,and the strategy of environmental education using exploratory learning and biological experiments is proposed.Five teaching cases related to environmental education including cell canceration,community succession,ecosystem stability,the impact of population growth on the ecological environment,and protection of our common home are designed.Infiltrating environmental education while teaching biology courses,enriching the theory and practice of environmental education,aiming to educate students from the perspective of educating the party and the country,educating students to pay attention to national and global ecological and environmental issues,and correctly understand the interaction between man and nature Dependency;help students acquire the knowledge and skills needed for harmonious coexistence between man and nature,cultivate emotions,attitudes and values that protect the environment,and lay the foundation for cultivating builders and successors of socialist causes with social responsibility and environmental literacy.
