How to infiltrate moral education in biology teaching is a purposeful activity for teachers to cultivate students' moral character. Today's middle school students are the generation of the new century, shouldering the heavy responsibility of building socialist modernization, and their healthy growth will directly affect their future lives. Moral education for students is an important task for middle school biology teachers. Biology is a science that reflects the occurrence, development, phenomena and laws of life activities. Of course, we must also attach importance to moral education. Infiltrating moral education into subject teaching is the main channel to improve students' ideological and moral quality. I think moral education should be infiltrated into biology from three aspects.

First, study the teaching materials carefully and combine the teaching contents to carry out moral education infiltration.

Teachers' responsibility is to teach and educate people. Moral education is an important part of subject teaching, but there is no ready-made written material for moral education in senior high school biology textbooks, which is easy to cause teachers to ignore the infiltration of moral education in teaching. At this time, teachers need to study the textbooks carefully, fully tap the potential moral education factors in the textbooks, and put moral education throughout the whole teaching process at ordinary times.

1, exploring the dialectical and unified viewpoint in the textbook.

(1) Dialectical Unity of Biology and Biology

Through the study of cell elements, students understand that all cells have a common material basis, which is composed of C, H, O, N and other chemical elements. These chemical elements can be found in the inorganic world, which embodies the unity of the biological world and the abiotic world. At the same time, the content of the same elements is quite different, which reflects the difference between the biological world and the abiotic world.

2. Patriotism education

Through the book Stability of Ecosystem, we know that China has a vast territory and a complex natural environment, which breeds extremely rich species and diverse ecosystems, but at the same time, China's biodiversity is also facing threats from different aspects. Through the explanation of these knowledge, students are not only proud of China's rich animal and plant resources, but also enhance their awareness of caring for the environment, protecting and rationally developing and utilizing natural resources, thus cultivating their sense of patriotism. Yuan Longping, the world's "father of hybrid rice" mentioned in the textbook, cultivated two-line hybrid rice, which is called the "green revolution" of grain production. Faced with great achievements, he once said: "What foreigners can do, we can do it, and what foreigners can't do, we will do it!" These achievements show the wisdom of China scientists and their great contribution to world science, and inspire students' patriotic enthusiasm.

3. Ideological and moral education

Some laws and regulations promulgated by the state are closely related to the content of biology teaching. For example, some provisions of grassland law, forest law, wildlife protection law, environmental protection law and marriage law can be explained in combination with relevant biological knowledge, so as to cultivate students' love for nature and establish the concept of obeying the law. Combine the teaching of adolescent sexual physiology and psychological knowledge, and carry out the education of treating friendship and love correctly. In the practice of biology teaching, we can carry out the education of cooperative spirit.

4. Education of scientific spirit, methods and attitudes.

Combine the teaching of the history of biological science with the teaching of infiltrating scientists' stories, and educate students to devote themselves to science. Through the example of transforming science and technology into productive forces, we should educate the scientific values. Establishing an ecological view and enhancing environmental awareness play an important role in improving citizens' quality. Tell the process of scientists' understanding of truth and educate them in scientific methods. Biology contains the viewpoint of system theory, permeates the systematic viewpoint in teaching, and is also the education of scientific understanding methods.

Second, guide inquiry and pay attention to students' initiative.

With the growth of students' age and IQ, individual self-education ability plays an increasingly important role in the development and improvement of their own moral character. Only by paying attention to cultivating and improving students' ability can teachers transform the internal contradictions of students' morality and make moral education work more smoothly and effectively. There are many students' experiments in high school biology, most of which are exploratory experiments. The so-called inquiry is to face practical problems first, then seek truth from facts, make bold assumptions in accordance with the established direction, and conduct exploration and research. This process is conducive to students to develop good thinking habits and enterprising scientific spirit. Teachers should make full use of these moral education materials in teaching, cultivate students' rigorous and realistic scientific attitude, and not be afraid of setbacks and difficulties.

Biology has a variety of teaching practice activities, and teachers should make full use of these opportunities to stimulate students' initiative and fully carry out moral education.

1, field practice and investigation: education of hard struggle, unity and friendship and safety should be carried out. Educate students to care for crops, flowers and trees, and cultivate the sentiment of loving nature. Use natural beauty to beautify students' minds and carry out aesthetic education.

2. Visit: We should educate students to establish a mass viewpoint, learn from the practical experience of local people with an open mind, learn from their advanced ideas and excellent qualities, and guide students to devote themselves to the economic development of their hometown.

3. Cultivation and feeding: practical education and labor education should be carried out. Guide students to find and solve problems, and cultivate tenacious will and indomitable spirit.

4. It is also an effective way of self-education to organize students to participate in social practice and carry out afforestation and environmental protection publicity activities on anniversaries such as "World Environment Day" and "Arbor Day".

The ancients said: "A year's plan is nothing like a tree valley; The ten-year plan is nothing more than a tree; A lifelong plan is nothing more than a tree. "Rome was not built in a day, and neither was teaching and educating people. In the process of biology teaching, we should adhere to the principles of from the superficial to the deep, from the surface to the inside, step by step, and gradually penetrate, so that students can acquire biological knowledge, establish a correct outlook on life and world, and form good moral quality, thus achieving the dual purposes of intellectual education and moral education.
