Due to the frequent occurrence of drug abuse, homicide and adolescent suicide cases, people pay more and more attention to life education, but there is still a great deviation in their understanding of life education.
1. 1 ignores the existence of other life and its rights and interests.
The focus of life education is only limited to human life, which seems to be a patent of human beings. It completely isolates human life from the lives of other creatures, and even "materializes" other lives to satisfy temporary curiosity and selfish desires, while ignoring the role of other biological life activities in maintaining biodiversity and ecosystem stability.
1.2 take life education as an organic part of political and ideological education.
In reality, life education is confused with political and ideological education, and moral education is overemphasized. The basic moral principles advocated by Confucianism have influenced generation after generation, and "the greatness of life and the glory of death" are also watering young hearts. In history, many people with lofty ideals gave their lives for their ideals and beliefs. Look at the highest state of moral evaluation again: giving up one's life and forgetting death, despairing about life and dying, while effectively protecting oneself in the face of danger is regarded as fear of death. Fan Meizhong, nicknamed "Fan Paopao", is a typical and pathetic one! For thousands of years, it has been praised as filial piety and ridiculous to "bury the child and report the mother, cut the stock and report the relatives"! Isn't this contempt for life and self-abuse?
1.3 There is still no consensus on whether life is equal.
There are two completely different views on life, one is to "materialize" life outside human beings and completely separate from human life; Second, life is completely equal. Therefore, people are puzzled: how can people be equal to other animals? While people are eating animal food, they are advocating and shouting the equality between people and animals. Funny! What rights and interests should life other than human beings have? The current life education does not give a reasonable explanation and answer.
2 the infiltration of life education
2. 1 Understand the magic of life
How is the life of a new individual born? Different creatures often reproduce new individuals in different ways. For example, the reproduction of angiosperms usually goes through the process of flowering, pollination and double fertilization, and then fruits and seeds are developed, and then offspring are propagated through seeds. In this process, if the pistil of the flower is damaged or not copied, the seed will not be formed. However, full seeds are only the internal conditions for angiosperms to reproduce. In order to germinate smoothly, seeds must also have suitable external conditions such as temperature, moisture and air. For another example, for humans, men produce hundreds of millions of sperm at a time, but only one can really enter the fallopian tube and combine with the egg, and eventually develop into an embryo. Embryos need to develop in the mother's womb for as long as 10 months before new life can be born. These examples make students realize the magic and hardship of life and how difficult it is for a new life to come into this world! Cherish life and love life.
2.2 Feel the preciousness of life
In the teaching materials, there are rich materials that can make students feel the preciousness of life. For example, "cell proliferation, aging and apoptosis" can educate students about life in time, so that students can understand that all living things have to go through a life course of birth, growth, maturity, aging and even death. People are born and die, and after death, like other creatures, they will eventually decompose into inorganic substances and return to nature. This is a law and an inevitable and important link in the course of life. "Falling flowers are not heartless things, but turning into spring mud will protect flowers more". It is in this constant alternation of life and death that the world presents a vibrant scene. Through the study of these knowledge, let students know that life and death are not mysterious. It is precisely because of the inevitability of death that it highlights the preciousness of life and urges us to seriously think about life, cherish and actively create the value of our own life, and strive to achieve our own life with a positive attitude. For another example, in the process of introducing the ecological functions of bacteria and microorganisms, let students know that although they are small, they have amazing adaptability, can survive and reproduce tenaciously in the harsh environment where human beings can't survive, and play an important role as decomposers in the ecosystem: decompose organic matter in animal and plant carcasses into inorganic matter, and then return to the inorganic environment for reuse by producers. Without the decomposition of these tiny creatures, the bodies of animals and plants will pile up like mountains, the ecosystem will collapse, and other life, including human beings, will not survive. It can be seen that any living individual, regardless of size, is a member of nature, has its right and value of survival, and any life is precious.
In addition, frustration education can also be carried out. Nine times out of ten, life is unsatisfactory, and setbacks are inevitable. Failure is the mother of success. Edison said: "failure is also what we need. It is as valuable to us as success." "Jiangdong children are versatile, and it is not known that they will make a comeback." With this mentality, we should enjoy failure and thank it. Mental health education and frustration education come down in one continuous line. In today's fierce social competition, parents' expectations, the pressure of study and the relationship between classmates may bring pressure to students. Without proper guidance and timely solution, they may feel depressed and depressed, which may lead to suicide or murder. We should educate students to correctly understand difficulties and setbacks and educate them to be optimistic. For example, compulsory biology course 2 in senior high school has a section on gene pedigree analysis and probability calculation. Students often make mistakes, and some have psychological fears. They are worried that they will encounter such related problems in the exam. In teaching, it is necessary to ease students' emotions in time, help students analyze the causes of failure, find appropriate methods, establish students' confidence and meet success.
2.3 Experience the harmony of life
Long-term evolution has created the harmony of life. This harmony is reflected in the relationship between biology and biology, and also in the relationship between biology and environment. Teaching should be good at infiltrating the harmonious beauty of life and cultivating students' feelings of appreciating and loving life. For example, the relationship between organisms is both intraspecific and interspecific. Mutual assistance among individuals within a species is not uncommon. Through the typical examples of ants, bees and wolves helping each other, let students understand the value of individuals and the significance of division of labor and cooperation, guide students to correctly handle the relationship between individuals and others, and cultivate the consciousness of harmonious coexistence with others. When learning the interspecific relationship, give examples of mutually beneficial symbiosis between different organisms, such as fungi and algae in lichens, leguminous plants and rhizobia. Through this harmonious relationship between creatures, students realize that all kinds of life are closely related, and human beings should respect the diversity of life, cherish and treat life well. When studying "internal environment and homeostasis in human body", we can relate the functions of each system, such as the respiratory system and digestive system absorbing oxygen and nutrients respectively, the urinary system discharging metabolic wastes, the circulatory system taking the responsibility of transportation, and the nervous system and endocrine system playing a regulatory role. It is the coordination of various systems that ensures the smooth progress of human life activities. Let students experience the beauty of harmony, unity and order in all the life activities.
2.4 Perceive the value of life
Engels' definition of life is: "Life is the way of existence of protein Group, and the basic factor of this way of existence lies in the constant metabolism with its surrounding external environment. Once this metabolism stops, life will stop, and the result is the decomposition of protein." From the biological point of view, it is defined as "life is a multi-molecular system composed of protein and nucleic acid, which has the ability of self-renewal, reproduction and reaction to the outside world". From the definition of life, we can see that human life is no different from the life of other creatures, and it is the existence of matter and the change of movement. Just because people are rational, we can't think that the dignity of human life is higher than other lives. For example, when talking about the value of biodiversity, it is mentioned that: firstly, it has direct utilization value, such as medicinal value (yew, honeysuckle, cicada slough, etc. ), industrial raw materials (reed for papermaking), scientific research value (research of gene bank), aesthetic value (cultivating sentiment, beautifying life, etc. ), etc. Secondly, it has indirect use value, such as ecological function, and finally it has potential use value that has not been defined by human beings. There are also compulsory 3 contents related to steady state and environment, which can make students understand the close relationship between different organisms and human daily life and their unique functions and values in nature, and guide and educate students to respect and cherish them.
In addition, the history of science has also entered our biology textbooks, which is also an opportunity for our teachers to carry out life education. The history of science combines the process and method of scientific conclusions with the learning process of biology, which can make students feel a heavy sense of history when learning knowledge, which is far more important than just understanding scientific conclusions and technological achievements. This teaching method can make students be influenced and guided by scientific thinking methods. Use the stories of scientists to reflect the process of scientific development and help students understand the history and development of science. Psychological research shows that successful role models can enhance students' sense of self-efficacy (the core component of motivation model), thus promoting students' progress; The life pursuit of scientists who are brave in pursuing truth and determined to benefit mankind is a very precious example material, which has obvious incentive and demonstration effect on the growth of students. For example, Schleiden and Wang Shi's cell theory, Swiss biologist Meshel's nucleic acid discovery, Linnaeus and binomial method.
Life education is an important part of quality education. Examples of great achievements in China's ancient and modern biological undertakings inspire students' patriotic enthusiasm and ambition to serve the country. For example, 1965, China has synthesized crystalline bovine insulin with biological activity for the first time in the world, which indicates that China is at the forefront in biomacromolecule synthesis. Yuan Longping, the "father of hybrid rice", has made great contributions to solving the problem of world food shortage. This series of facts shows that the Chinese nation has a long history, and the people of China are smart people who can make great contributions to mankind, thus inspiring students' national pride and self-confidence.
2.5 Imagine gratitude and learn to be grateful.
There is a song called "Grateful Heart", and the lyrics say: "Although the world is wide, it is hard to go. I have seen all the ups and downs in this world, and how many tears there are. I want God to know that I don't admit defeat. Grateful heart thanks you and gives me the courage to be myself all my life. A grateful heart thanks fate, and I will cherish it when flowers bloom and fall. " Whether it is a person's natural life, social life or spiritual life, it should not be completely personal. As the undertaker of life system, human body has no right to dispose of life. Let students know how hard it is for parents to raise you from the aspects of reproductive development, food, clothing, housing and transportation, and how many people in society serve you. We should know how to be grateful and learn to be grateful. Your mother was pregnant in October to protect you from coming into this world. Parents, relatives, friends, teachers and classmates are all concerned about your growth, and the society provides a good environment and conditions for your growth as much as possible. How many people devoted their efforts and labor to the gestation, birth and growth of human life, and how many people suffered when you lost your life. Crows can feed back, sheep can kneel and milk, and human beings should know how to be grateful. Be kind to yourself, cultivate a good interest in life and maintain a good mental state. A healthy life is not only the direction of my life's efforts, but also the social responsibility of giving back to my parents and their society.
The course of life is difficult, so we should learn and experience constantly and learn to feel the preciousness of life. Life is also lonely, so we should develop love and help each other and learn to be grateful. In biology teaching, students should learn life knowledge from the perspective of life education, which is the basis of life education and irreplaceable by moral education and any other education. As long as we teachers pay more attention to our students in classroom teaching and care for our students, instead of just staying at the level of knowledge classroom and implementing life education, I think our classroom will be full of vitality and life will always be there!
