Biology is a basic subject in natural science, and it is a science that studies life phenomena and laws of life activities. It is the foundation of agricultural science, medical science, environmental science and other related science and technology. The research of biology has experienced the development process from phenomenon to essence and from qualitative to quantitative. Nowadays, it has developed very rapidly in both micro and macro directions, and is more and more closely integrated with information technology and engineering technology, which has a greater impact on society, economy and human life.

Biology course in senior high school (hereinafter referred to as this course) is one of the important subject courses in the field of science, and it is the continuation and expansion of related courses in compulsory education. Its essence is to show the basic content of biology and reflect the essence of natural science. It can not only enable students to acquire basic biological knowledge, but also enable students to understand the views held by biologists in the research process and the ideas and methods to solve problems. Biology curriculum requires students to actively participate in learning, acquire biological knowledge, form the habit of scientific thinking, form a positive scientific attitude, and develop lifelong learning and innovative practical ability in the process of asking questions, obtaining information, looking for evidence, testing hypotheses and discovering laws.

For the interpretation of "Biology Curriculum Standard for Ordinary Senior High Schools (20 17 Edition)", we will start from the following four aspects:

1. Senior high school biology core literacy;

2. High school biology curriculum content standard;

3. High school biology academic quality standards;

4. Suggestions on the implementation and evaluation of senior high school biology curriculum.

What this issue brings to teachers is an excerpt from the course "Interpretation of the New Curriculum Standards of Biology in Senior High School-Core Literacy of Biology in Senior High School".

Subject core literacy is the concentrated expression of the value of subject education, and it is the correct value concept, necessary character and key ability that students gradually form through subject learning. The core literacy of biology discipline includes outlook on life, scientific thinking, scientific inquiry and social responsibility.

1. Life concept

The concept of "life" refers to the abstraction after explaining the observed life phenomenon and its relationship or characteristics. It is people's view after argumentation, and it is the consciousness, concept and thinking method that can understand or explain biological related events and phenomena. Students should form life concepts based on a better understanding of biological concepts, such as structure and function, evolution and adaptation, steady state and balance, matter and energy. We can use the concept of life to understand the diversity, unity, uniqueness and complexity of biology, form a scientific view of nature and world, and use this as a guide to explore the laws of life activities and solve practical problems.

2. Scientific thinking

"Scientific thinking" refers to the thinking habit and ability of respecting facts and evidence, advocating rigorous and pragmatic knowledge attitude, and using scientific thinking methods to understand things and solve practical problems. Students should gradually develop scientific thinking in the learning process, such as being able to explore and explain life phenomena and laws by using induction and generalization, deduction and reasoning, model and modeling, critical thinking and creative thinking, and investigate or demonstrate biological social problems based on biological facts and evidence.

3. Scientific inquiry

"Scientific inquiry" refers to the ability to find biological problems in the real world, observe, ask questions, design experiments, implement plans and exchange and discuss results for specific biological phenomena. In the process of inquiry, students should gradually enhance their curiosity and thirst for knowledge about natural phenomena, master the basic ideas and methods of scientific inquiry, and improve their practical ability; In the process of inquiry, I am willing and good at teamwork and innovation.

4. Social responsibility

"Social responsibility" refers to the responsibility and ability to participate in the discussion of personal and social affairs, make rational explanations and judgments, and solve production and life problems based on biological understanding. Students should be able to actively use biological knowledge and methods, pay attention to social problems, participate in discussions and make rational explanations, so as to distinguish superstition from pseudoscience with attitudes and values that benefit mankind; Combine local resources to carry out scientific practice and try to solve real life problems; Establish and practice the concept of "clear water and green mountains are priceless treasures", form ecological awareness and participate in environmental protection practice; Actively publicize the concept and knowledge of caring for life to others, advocate a healthy and civilized lifestyle, and become a promoter and practitioner of a healthy China.

The core quality of biology is gradually developed by students in the process of learning biology courses. The values, necessary character and key ability shown in solving practical problems in real situations are the comprehensive embodiment of students' knowledge, ability, emotional attitude and values. The cultivation of core literacy in biology should run through the compilation of teaching materials, classroom teaching and examination evaluation.
