Several manifestations of life education in life

What are the problems in life and education? The connotation of education is extremely rich, and the important goal of today's education is to cultivate people with comprehensive quality and sound personality. The important content of "all-round quality" is the intersection, superposition and integration of scientific literacy and cultural literacy-humanistic literacy. However, China's traditional education, especially the exam-oriented education, pays too much attention to the teaching of logical and systematic scientific knowledge and theory, ignores the cultivation of students' humanistic quality, and lacks the people-oriented concept, which leads to the abandonment of humanistic spirit in education and the loss of educational humanistic significance and value. Biology is a natural science. How to combine biological knowledge with humanistic education in biology teaching, guide students to form a correct world outlook, outlook on life and values, and create a social environment in which man and nature live in harmony has attracted the attention of education circles. This is also an important issue that I have been thinking about and trying to explore and practice for a long time.

We are often deeply troubled by the abuse of life in society. Why do some people get tired of life and commit suicide because their wishes are not met or they encounter setbacks? Why do people kill people because others are in their way? Why does cruelty to all kinds of animals happen from time to time? The reason is that these people don't know the preciousness of life, and they don't know how to cherish themselves, others and others' lives. Nowadays, most only children only know how to enjoy the material wealth created by the previous generation and the care of their parents, but they seldom care about others and society, and don't understand that the survival of all kinds of creatures is a right endowed by nature. Although biology is a science that studies life, the traditional biology teaching ignores the life education of students and pays too much attention to the teaching of biological knowledge and basic skills. In preparing lessons, teachers aim at whether students can master book knowledge and pass various exams, and rarely explore the humanistic education content contained in these contents, and rarely consider the combination of biology teaching with students' real life and health and social reality. The new curriculum standard clearly requires that biology teaching should not only enable students to acquire relevant knowledge, but also promote their physical and mental health development; Pay attention to life and society; Understand the significance of harmonious development between man and nature, and establish a positive and healthy attitude towards life; Wait a minute. In other words, the new curriculum standard puts forward clear requirements for humanistic education in biology teaching. In fact, each chapter contains a lot of materials for humanities education. As long as we analyze and understand the requirements of the new curriculum standards from the background of big education, we can organically combine the teaching of biological science knowledge with the cultivation of humanistic spirit in biology teaching, so as to educate students in life.

1. Precious life-biological reproduction

There are a lot of biological reproduction contents in junior high school biology textbooks. We can use this knowledge to make students realize that life is hard-won, and then cultivate students' humanistic feelings of loving, cherishing and caring for life. For example, the reproduction of angiosperms usually goes through the processes of flowering, pollination (self-pollination or cross-pollination) and double fertilization, and then gradually develops fruits, produces seeds and reproduces offspring. In this process, if the pistils of flowers are damaged or not pollinated, fruits will not develop normally and seeds will not be formed, and full seeds are the basis for angiosperms to reproduce their offspring. Another example is the breeding of birds, which has to go through the process of selecting nesting areas, selecting materials to build nests, mating and laying eggs, and then brooding and incubating eggs. No matter which link goes wrong, it is difficult for future generations to survive Another example is human reproduction. Men can produce hundreds of millions of sperm at a time. They scrambled to swim from the uterus to the fallopian tubes of women's vaginas. When they reached the fallopian tubes, there were only a few thousand left. Finally, only one sperm can bind to an egg cell. The fertilized egg develops in uterus 10 month. It can be seen that everyone is unique and the best individual in the world. How hard-won and precious life is! Any life is a member of nature and has the right to exist. Only when we fear life can we cherish life. Whether it is plants, animals or people, we should cherish life.

2. The decline of life-return to nature

The birth of life is joyful, and the decline of life is inevitable.

For a long time, due to the influence of traditional culture, people avoid discussing the issue of death and expect good luck and peace. However, the frequent self-destructive behaviors such as campus suicide reveal that many teenagers are extremely fragile, unable to cherish their lives, and do not really understand the meaning of "death". Some young students give up life and choose to die when they are under great pressure (such as study pressure, psychological pressure and high expectations of parents and teachers). This kind of escapism and contempt for life is irresponsible to oneself, family and society, and it is also a manifestation of not facing up to "death". "Death" is not only a problem of biological category, but also a problem of sociology, philosophy, ethics and humanities. In this regard, we can educate students about life and death from the perspective of biology in biology teaching, so that students can cherish life more and enhance the value of life. Any living thing has to go through the process of birth, growth, illness, old age and death. For example, in autumn, fallen leaves will go through a delamination process at the base of a petiole-blown off by the wind, while in spring, trees will still give birth to new leaves and reproduce vitality; Single-celled animals can split into two new lives when they grow to a certain time, and the original individual no longer exists; People will also be born and die. After death, people, like other creatures, 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. No life, no death, no death, no life. "falling red is not a heartless thing, but turning into spring mud protects flowers more"! Only by knowing death correctly can we look at life positively, understand the meaning of life, assume the responsibility of survival, and then create and integrate the meaning and value of life.

3. Harmony of life-biological adaptability

Why are the psychological problems among young students getting more and more serious? In addition to the influence of social environment, teenagers lack self-regulation ability and poor adaptability are also important factors. In view of this, emphasizing the adaptability of biology in junior high school biology teaching will also inspire and educate students. Here, two adaptations are particularly emphasized-the adaptation of biological structure and function, and the adaptation of biological morphological structure and living habits. For example, the epidermal cells of leaves are transparent so that sunlight can penetrate, and mesophyll cells contain a large number of chloroplasts suitable for photosynthesis; Small intestinal villi contain capillaries and lymphatic capillaries suitable for absorbing nutrients. No living thing can live independently from the environment, but must have a relationship with the environment. The survival of living things will affect the environment. Similarly, the environment will also affect the survival of living things. For example, plants living in desert areas for a long time have short plants and small or even needle-shaped leaves, which reduces the loss of water; Frogs living in grass are grass green, while frogs living in sand are tan; Carnivorous mammals have sharp canine teeth; Wait a minute. It is conceivable how harmonious and wonderful this mutual adaptation is! If this harmony is destroyed, diseases will appear in organisms, health will be threatened and the quality of life will decline. It is precisely because of biological adaptability that colorful nature and all kinds of life have emerged. From low to high, from simple to complex, from ocean to air, from tropical jungle to snow-capped mountains, there are no traces of life and no colors of life everywhere. Therefore, in biology teaching, on the one hand, we should stimulate students' interest in exploring scientific mysteries, make them learn and understand the characteristics of biological adaptability, apply what they have learned, and pay attention to the harmony of nature and the harmony and health of life; On the other hand, students are required to learn and understand the adaptability of biology, and think about why some students have strong adaptability, while others find it difficult to adapt to the new environment, resulting in lack of interest in learning, decline in grades and even psychological obstacles. Specifically, biology teaching should be suitable for students' reality, teach students in accordance with their aptitude, enable students to enhance their adaptability to complex environment, learn to respect and care for others, and cultivate a sense of social responsibility, so as to lay a good foundation for going to society and serving the society in the future.

4. The greatness of maternal love-the changes of mothers during pregnancy and childbirth.

Mothers not only gave birth to new life, but also cultivated latecomers for human development and future creation. However, in reality, it is not uncommon to fail to support elderly parents, abuse their parents or even kill their parents. The reason lies in the expansion of some teenagers' selfish desires, thinking that they are considering their own needs and have not really understood their parents' upbringing, parents' hearts and parents' love. A person who doesn't even love his parents can't love others, let alone his motherland. Needless to say, the traditional junior high school biology teaching also has some disadvantages. For example, for the content of human embryo development and nutrition, teachers and students just regard it as knowledge to learn. In order to cope with the exam, it seems that it is enough to remember the place of embryo development-uterus, the structure of material exchange-placenta, and the development time in the mother-280 days. In fact, if we teach this part of knowledge and carry out maternal education at the same time, we can realize the organic combination of scientific knowledge and humanistic spirit. Before the lecture, the author assigned the students an investigation assignment: go home and visit their parents (mainly their mothers, and discuss the interview in groups). The contents of the interview include the changes of mother's psychological and physiological changes and dietary preferences during pregnancy preparation and early, middle and late pregnancy, as well as the changes in the production process and postpartum period, and so on. Everyone writes an interview or investigation report, which will be part of the final grade. Two weeks later, the students handed in their homework: some wrote "My Birth", some wrote "Mom and Me", and some wrote "Mother's Pregnancy Investigation Report". In these assignments, some focus on the psychological changes of the mother during pregnancy, describing the daily verbal dialogue and touching actions of the mother to the fetus in the womb and the process of welcoming the new life with hope; Some focus on consulting the weight gain data of various organs of the mother's body after pregnancy and describing the changes of the mother's body; Some people are concerned about the complicated feelings of pain and joy of mothers during childbirth. Throughout these articles, no matter where the focus is, they all reveal the children's reverence for their mothers, sigh their greatness and say sincerely: I love my mother!

5. The meaning of life-physiological and psychological characteristics in the process of growing up

Man is the soul of all things. People live not only to live, but also to make limited life meaningful and valuable. What is the value of life? There is an advertisement on TV, interviewing the shepherd boy-the reporter asked: Why do you herd sheep? A: Gai Lou. Q: What is Gai Lou doing? A: Get married. Q: Why get married? A: Give birth to a baby. Q: Why do you want to have children? A: herding sheep. This advertising dialogue only illustrates people's viability. In fact, people's viability is not much different from that of animals. How to make life more valuable? The author believes that a person should have a healthy body and tenacious vitality. The new curriculum standard clearly points out that if students "gradually develop good living and health habits and establish a positive and healthy attitude towards life", especially teenagers, are in a period of rapid physical growth and development, it is necessary to combine biology teaching with related content to carry out health education for students. For example, combined with the study of "sports", we can understand the common diseases and prevention of sports system, make our own physical exercise plan, and actively participate in sports activities; Combined with the study of digestion and absorption, my family and I made a meal plan and designed scientific and reasonable daily recipes. Combined with neuromodulation study, make your own reasonable work and rest plan and study plan, arrange time reasonably, combine work and rest, and so on. The second is to have rich knowledge, wisdom and ability. Only by studying hard and constantly improving their comprehensive quality and ability can we pursue a high-quality life. Adolescence is not only the fastest period for a person to grow and develop, but also the key period for learning knowledge, opening wisdom, enhancing ability and forming world outlook, outlook on life and values. At the same time, it is also the most prone to psychological problems and psychological obstacles. According to relevant data, there are 1 person in every 8 primary and middle school students with sub-health. Therefore, it has become an important task for middle school education to help students pass adolescence smoothly and form a correct outlook on life and values. In this case, biology teaching should shoulder its own responsibility. Specifically, biology teaching can combine the actual situation of adolescent students' physiological development and psychological changes, explain the knowledge about the human body, let them know and understand themselves, and solve the mystery of human physiological phenomena, so as to successfully spend adolescence. For example, when teaching "Human Development", the author did not let students know the development process and changes, the characteristics of sexual development, the physical hygiene of adolescence and the knowledge points of memory like traditional teaching, but made the following comparative analysis: ① When I was in the fourth and fifth grade of primary school (about 9- 10) and now (about 12-65438) ② Yours. (3) What are the psychological changes during growing up? How did you solve these problems? Is there any problem that you can't solve by yourself? Students summarize this participatory learning through their own analysis, comparison and group discussion. Everyone can correctly understand all kinds of changes in adolescence and calmly deal with all kinds of problems in adolescence, so as to establish a positive and optimistic attitude towards life, study hard scientific and cultural knowledge and enhance the meaning of life.

Science education without humanities education is incomplete. Especially with the development of biotechnology, humanistic education with life education as the core has become more and more important. In the book "Education for Life", J.Donald Walters clearly stated at the beginning: "Education is not only to train students to get a career or pursue knowledge, but to guide people to fully understand the meaning of life; Life is just a process of life. Since you are alive, it is better to live well and let the attitude of life with both body, mind and spirit become a new element of future education. " Education should be people-oriented and emphasize the value and dignity of people. As biology teaching in basic education, we should shoulder the heavy responsibility of life education, combine biological knowledge with humanistic education, carry out correct world outlook, outlook on life and values education, and pay attention to cultivating students' humanistic spirit. Every student should respect, love and cherish life.
