On the Cultivation of Students' Core Literacy in Biology Teaching The core literacy of students' development refers to the necessary character and key ability that students should have to meet the needs of lifelong development and social development. It is comprehensively manifested in nine qualities: social responsibility, national identity and international understanding (social participation); Humanistic background, scientific spirit and aesthetic taste (cultural accomplishment); Physical and mental health, learn to learn and practice innovation (independent development). Put the core literacy system in the basic position of deepening curriculum reform and implementing the goal of moral education. "Core literacy" refers to the essential character and key ability that students should have to meet the needs of lifelong development and social development. It emphasizes personal cultivation, social care and feelings for home and country, and pays more attention to independent development, cooperative participation and innovative practice. Subject core literacy is the concretization of core literacy in a specific subject (or research field), which is formed after students study a subject (or research field) and is the concentrated embodiment of the educational value of the subject. Specific to biology, the expert discussion draft of the Ministry of Education has formulated four key expressions, namely, outlook on life, rational thinking, scientific inquiry and social responsibility, or it can be understood as four contents: understanding and respect for life, cherishing and awe of nature, cognition and practice of science and technology, and responsibility and responsibility for society. The concept of life generally refers to people's overall understanding or views on life, including not only people's fundamental views and attitudes towards life and death, but also people's judgments on the value of life. Students' knowledge of life outlook mainly comes from social media, followed by self-study and school education. Biology teaching is the main way for students to acquire the concept of life in school education. It enables students to develop a good life orientation and guide them to actively and vividly discuss life, so as to realize the value and significance of life and find the true meaning of life. Guiding students to cherish life and pursue the meaning of life through teaching materials is the main way of life view education. Philosophers and logicians regard reason as a process based on logic and reasoning, that is, reason is thinking under the guidance of logic. Rationality is a unique advanced cognitive processing mode of human beings. It can even affect the results of all aspects of people's lives more than intelligence or other cognitive abilities, including academic performance, decision-making satisfaction, mental health, and even violations or moral behavior. It is the basic task of biological science to promote the development of students' rational thinking through the study of biological science. Set some controversial questions in the textbook to let students develop their "rational thinking" in the debate; Conduct experimental design and analysis under the guidance of logic, so that students can exercise "rational thinking" in practice; Open-ended questions are set in after-class exercises, so that students can cultivate their "rational thinking" in practice. Scientific inquiry refers to various activities carried out by students to acquire knowledge and understand scientists' scientific ideas and methods of studying nature. In high school textbooks, teachers should guide students to carry out scientific inquiry in a planned way, so that students can think like scientists and explore like scientists. Only in this way can we stimulate and improve students' interest in learning biology, improve their enthusiasm and thirst for knowledge, and stimulate their innovative consciousness. For example, the senior high school biology textbook published by PEP attaches great importance to the introduction of the history of science. For example, before describing the content of fluid mosaic model of biofilm, the exploration process of biofilm structure by scientists such as Irvington, Sanger and Nixon is described, so that students can appreciate the hardships of scientific exploration and the tireless enthusiasm and efforts of scientists. So as to cultivate middle school students' interest in scientific inquiry and lay the foundation for future learning innovation. Social responsibility specifically refers to the tasks, responsibilities and missions that individuals or organizations should undertake to others and society, and it is the responsibility that individuals or organizations should do for the happiness of others and the development and progress of society. Moral education has become the fundamental task and premise of education. Teachers should improve the scientific literacy of the whole people through biology education, make students pay more attention to social reality and social problems, form correct scientific values, cultivate students' sense of responsibility for the natural environment and become qualified modern citizens. For example, in the high school biology textbook published by People's Education Publishing House, the chapter "Immune System" introduces, investigates and discusses the prevention and treatment of infectious diseases, the emergence of antibiotics and drug resistance, AIDS knowledge, smallpox virus, biological weapons, etc., so that students can form noble moral sentiments such as caring for society, caring for the environment and caring for mankind, and establish a correct outlook on life and values.
