The times call for middle school biology teaching to attach importance to life education.
From a global perspective, the current lack of human life consciousness is manifested in two aspects: First, the living environment of human beings has been seriously damaged. In the process of transforming nature, human beings often do not respect and care for the lives of animals and plants for immediate interests. A series of problems such as ozone layer destruction, biodiversity imbalance, domestic garbage, energy crisis and nuclear war threaten human life. The rare flood disaster in China from 65438 to 0999, and the sandstorm in the north in recent two years, are the serious consequences of vegetation destruction. Second, the phenomenon of homicide and suicide among teenagers is serious. In recent years, the phenomenon of youth violence, suicide and homicide is very serious all over the world, and China is no exception. Zhang is a college student in Beijing. Because of his failure in the exam, he is under great psychological pressure. He killed his father and grandmother with a hammer. A student named Xiao Dan 14 years old was considered as a poor student by the teacher because of his poor grades. He felt that he had failed his parents' expectations, that living was worthless, and committed suicide. Zhou, a sophomore in a school, committed suicide by taking more than 40 sleeping pills because she found her pet dog was given away. This shocking fact reflects that some students are becoming more and more indifferent and even cold to life.
The above facts show that it is very important and urgent to strengthen human life education. Teenagers are the hope of the future, and paying attention to their life education can fundamentally solve the above problems. Biology has unique advantages in life education for students. On the one hand, biology is a science that studies the law of occurrence and development of life. Only by knowing and mastering the laws of life can we better respect and care for life. On the other hand, in the 20th century, a series of epoch-making research achievements appeared in life sciences, and their scientific theories and methods had a great influence on other disciplines. The development of life science plays a key role in human development. The "Biology Curriculum Standard" promulgated by the state clearly puts forward "to cultivate students to love nature, cherish life, understand the significance of harmonious development between man and nature, and raise awareness of environmental protection". Therefore, we should attach importance to life education in biology teaching and cultivate students' respect and love for life.
Second, the connotation of life education in middle school biology teaching
Life education is to let students know life, guide them to appreciate life, respect life, cherish life and establish correct life values.
1. Helping students understand life biology is a science that studies life phenomena and their laws. Teachers should teach students the gestation, development and activities of life, and at the same time let students fully understand and understand life. First of all, let students realize the difficulty of life in nature, life is only once for a biological individual, so as to realize the preciousness of life; Secondly, let students look at the phenomenon of life correctly and realize the greatness and sublimity of life and the smallness and fragility of life; Thirdly, let students correctly understand and grasp the connotation of life, which is both common and full of uniqueness and difference, and also let students realize the existence value of every life in nature, so as to help students know themselves, guide them to appreciate their uniqueness, discover their potential and give full play to their life accumulation.
2. Guide students to appreciate the types, shapes and colors of life in nature. When teaching biological morphology and structure, let students feel the beauty of morphology and structure: through the study of the unity of biological structure and function and the adaptation of biology to the environment, let students feel the beauty of harmony between biology and biology and nature, and finally let students feel or experience the beauty of life, so as to appreciate life.
3. Expect students to respect life. When students know life, understand its mystery and feel its beauty, they will appreciate and praise life, and then gradually form a belief of respecting life. Through the study of biology and environment, students can understand and pay attention to the environment on which all life depends, respect life and keep its safety and naturalness. As teachers, we should set an example and respect students' personality and individuality, so that students will feel that their lives are valuable, respect their own lives, and at the same time respect and care about others' lives.
4. The ultimate goal of encouraging students to cherish life education is to cherish life. To really put it into action, we should start with cherishing life, educate students not to climb flowers and trees, trample on grass, dig nests, bully small animals, eat rare animals and plants, waste animals and plants as experimental materials, waste resources and consume excessively, so that they can form the habit of cherishing life and truly reflect the significance and value of human existence in life.
Thirdly, make use of the advantages of biology to infiltrate life education into classroom teaching.
In classroom teaching, we should give full play to the advantages of biology, guide students to understand that life is the most wonderful and fascinating natural phenomenon, that people must live in harmony with other lives, and that human life is precious, so as to cultivate students to respect and care for their own and others' lives.
1, guide students to know that life is great and cultivate students to respect life. Life has evolved naturally through countless years, and this process is difficult. After the emergence of life, single-celled life has undergone a long evolution, and more complex life forms have emerged. Finally, people with high intelligence and high emotions have emerged-this further embodies the greatness of mankind. When I was teaching "Biodiversity", I introduced the bat's "echolocation system" and "animal language" and other life phenomena to students, which made them feel the wonder of life. So as to cultivate students' feelings of respecting and loving life.
2. Guide students to understand the relationship between man and nature, and cultivate students to love life. Before this century, people were still immersed in the excitement of digging more and more wealth in another place, but when they woke up overnight, they suddenly found that the earth was not an inexhaustible treasure house of resources, and many non-renewable resources were gone forever. Therefore, we must know and protect nature. We must clearly realize that man is a part of nature, and nature is always the mother who nurtures human beings and the last boundary of human development. When I teach biology and environment and people in the biosphere, I guide students to investigate the surrounding ecological environment, understand the relationship between biology and environment, and cultivate students' feelings of loving nature and caring for biology.
3. Guide students to understand the shortness of human life and cherish the lives of themselves and others. Every life is unique and irreplaceable to an individual and deserves everyone's love. When I taught the section "Reproduction, Development and Inheritance of Organisms", I made the students realize that life came into this world as a very accidental opportunity. Every life always includes the process of birth, growth and death. This life course is short and precious. I design such a question for students to discuss: Life is short, how can a person exert his life potential, make his life meaningful and realize the value of life? Through heated discussion, we all realize that life is meaningful and valuable only if we care about others, cherish our time, succeed in our studies and do something for our country.
Fourth, combine inside and outside class to cultivate students' respect and love for life.
Only by renewing the concept and reforming the teaching mode can biology teaching effectively educate students and better cultivate their ability to respect and love life. I made the following attempts in biology teaching.
1, implement open classroom teaching. The first is the openness of teaching content. In biology teaching, I not only rely on textbooks to guide students to learn the textbook content well, but also pay more attention to students' existing life experience, closely combine the textbook content with the actual ecological environment around students, stimulate students' interest in learning biology and deepen their understanding of biology and environment. The second is the opening of teaching form. When teaching the section "Green Plants in the Biosphere", I led the students into the yellow-green space. The students walked into the endless green space, with clear birds singing in their ears and flowers and leafy plants in front of them. They feel the tranquility and loveliness of nature. Through field observation and appreciation, students can realize that green plants are the most important creatures in the biosphere, which play a decisive role in the existence and development of the biosphere and are closely related to human life, thus cultivating students' strong consciousness of loving life and protecting the environment.
2. Guide students to carry out research-based learning activities. I instruct students to learn the contents of biology after class and during holidays, and carry out independent inquiry learning activities according to the surrounding ecological environment and their own interests. First of all, research projects can be chosen independently. The topics chosen by students are varied and colorful. Such as "the growth conditions of bean sprouts" and "the living habits of earthworms" and so on. Second, independently design research activities and independently arrange research processes; The third is to exchange and display research results. Through personal observation and investigation, students write papers, closely combine biological knowledge with the surrounding ecological environment, deeply understand the significance of harmonious development between man and nature, improve environmental awareness, and cultivate feelings of loving life.
3. Organize students to actively participate in all kinds of activities that care for life. First, seize the events that are widely concerned by the society and inspire students to love life. The newspaper published "A bear wounded a student in Tsinghua University" and "A college student put a dog in the microwave oven to observe the incident", which became the focus of media attention and the central topic of discussion. I seize this kind of animal injury, organize students to read relevant newspapers first, and then discuss this kind of incident. Many students said that once my hand was scalded by boiling water, and the pain was unbearable. How can this bear tolerate food soaked in sulfuric acid? How cruel! Some students say that bears are also life, so we should treat them well. Through reading newspapers and discussing, we can awaken students' life conscience and arouse their care and love for life. The second is to organize students to participate in relevant festival activities and cultivate students' habits of caring for the environment and loving life. "3. 12" Arbor Day, "4.22" Earth Day, "6.5" World Environment Day and "Bird-loving Week" are all good opportunities for students to carry out ecological education. I organize students to take an active part in such Sunday activities.
Life education is an indispensable part of modern education, an important content of quality education, and the need to cultivate future citizens with sound personality. Therefore, every biology teacher should constantly enrich the theoretical knowledge related to life education, establish a correct outlook on life, values and life and death, and combine life education with his own teaching practice. Share your feelings and experiences about life with students, so that students can fully feel the vitality and happiness of life.
