First, the meaning and characteristics of life education
There are two kinds of life education: broad sense and narrow sense: narrow sense refers to the concern for all natural life (including the lives of individuals and others); Broadly speaking, it is a kind of holistic education, which includes not only paying attention to life, but also cultivating survival ability and improving the value of life. Therefore, the so-called "life education" means paying attention to both science education and humanities education in the process of implementing education, so that teachers and students can grasp the meaning of the world and life in life activities, improve the quality of life, emancipate the spirit and cultivate life consciousness, so as to achieve success and enjoy the happiness of life.
Life education should have the following characteristics: ① Construct wisdom education, which includes moral wisdom, rational wisdom and emotional wisdom. Life education should first be full of "moral wisdom", which is the basic value of human nature. Life education is to let students experience and feel something. Rational wisdom means that teachers guide students to correctly think about various conflicts, contradictions and obstacles in an open way of thinking, and learn to live with others in conflicts. Emotional wisdom is a kind of aesthetic wisdom, and the life education we teachers should think about is not to transfer book knowledge to students' minds. ② Education that points to the growth of life. Professor Ye Lan proposed that classroom teaching should be full of vitality, and the classroom should truly reflect students' activities as a real person. Life education should be a situation and a teaching process, so that students can have an epiphany and understand their own understanding of life. Life education requires teachers to bend down humbly and patiently and listen to students' stories. ③ Effective education. Life education must be the reorganization of students' original experience and arouse students' new understanding of life experience.
Second, the practice of life education in biology classroom
1. The starting point of life is not easy.
In reality, it is not uncommon for teenagers to be inconsiderate of their parents, fail to support their elderly parents, abuse their parents and even kill them. Such a scene is sad and worth thinking about: what caused it? The reason is very complicated, but I think it has something to do with teenagers' ignorance of life and life. Combined with the knowledge of biology textbooks, I will let students know about the development and delivery of human embryos and let them experience the starting point of life, which is hard-won.
In senior high school biology textbooks, the chapter "Embryo Engineering" briefly introduces the process of embryo development. I mainly educate students through science and education short films and movies. For example, in "Human Reproduction", men can produce hundreds of millions of sperm at a time, and they scramble to swim across the uterus in women's vaginas to reach the fallopian tubes. When they reach the fallopian tube, there are only a few thousand left, and finally only one sperm can combine with the 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.
In order to let students know the pain of their mother's childbirth and the hardships their parents have paid for their arrival, I let them watch the film Sunflower by the sixth generation director JASON ZHANG, which begins with the birth of the protagonist Zhang Xiangyang and ends with the birth of his son. Especially the bloody and real delivery scene at the end, which really shocked everyone. I noticed that many girls even closed their eyes and dared not look. But everyone, including them, came into this world in this way. How difficult and difficult it is to conceive and be born of life!
After this baptism of life again and again, many students' attitudes towards their parents have changed after returning home, and many parents have told me that their children have grown up a lot, as if they had grown up overnight. These changes are very gratifying.
2. The growth of life, the value of life
Man is the soul of the universe. People live not only to live, but also to make limited life meaningful and valuable. The new curriculum standard clearly puts forward that students should "gradually develop good living and hygiene habits and establish a positive and healthy attitude towards life", especially teenagers, who are in a period of rapid physical growth and development. It is necessary to combine biology teaching with related contents to carry out health education for students.
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. Biology teaching can explain teenagers' physiological and psychological knowledge in combination with the characteristics of the subject, let students know themselves and solve the mystery of human physiological phenomena, so as to successfully spend adolescence.
For example, in the teaching of Individual Development, I try to make the following comparative analysis: ① Compared with primary schools, what are the differences in your learning methods, learning efficiency, memory and understanding (for example)? Why? ② When was your menarche (or first nocturnal emission), what was your psychology at that time, and how to deal with it? (3) In the process of growing up, what are the psychological changes, what puzzles have you encountered, how to solve them, and are there any problems that you can't solve yourself? Through their own analysis and comparison, group discussion, the whole class summed up this kind of self-help learning, so that everyone can basically correctly understand and calmly deal with various changes and problems in adolescence, thus establishing a positive and optimistic attitude towards life, studying scientific and cultural knowledge hard and enhancing the meaning of life.
Adolescence, during which students are in a period of heavy learning tasks. For example, combined with neuromodulation study, make a reasonable schedule and study plan, arrange time reasonably, and combine work and rest. Only by studying hard and constantly improving their comprehensive quality and ability can we pursue a high-quality life.
3. The end of life, the treasure of life
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. Some teenagers give up survival from time to time and choose to die. 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.
For example, in autumn, fallen leaves will go through a separation 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.
4. Continuation of life, harmony of life
At the beginning of the ecological chapter of the biology textbook, it reads: "There are many lives on this planet besides us, which also need us to cherish. We are not the only inhabitants on the earth, nor are we the earliest inhabitants. There are many lives living with us, and their existence is very important to us and our planet. We also need our care. " Environmental pollution is serious, wild animals are endangered, docile animals attack villages, and so on. These images that shock us but turn a blind eye often happen. Why do we ignore them? Because we despise and don't care about other lives. Therefore, we should also infiltrate the attention education to other natural life in biology class.
For example, in the chapter on ecology, I will find some materials for students and arrange to show some clips of the Hollywood movie Birds. The horror scene of birds killing people because they violated their living space will make students unforgettable all their lives, and they will pay more and more attention to and cherish other lives. I remember watching the clip that night, a cicada flew into the classroom. After being caught by the students, the other students immediately said, "Let go." This is a very good effect.
Third, the reflection of life education in biology classroom practice.
1. Create a situation full of conflicts.
Classroom situations should be conducive to students' experience and epiphany, but also full of conflicts. The situation of classroom teaching is not only discussion and communication, but also vivid activities. It is also a good epiphany to calm down and meditate. It is also a good way to release soft light music in class and let students feel an aesthetic experience.
2. Introduce icing on the cake cases
The teacher reads some stories and tells some real stories in class, which gives students emotional shock. Through the discussion among the students, the teacher made the students realize that what was behind the case was more important.
3. Life education is closely related to biology teaching.
Biology education without life education is an incomplete science education. As biology teaching in basic education, we should shoulder the heavy responsibility of life education, combine biological knowledge with life education, carry out correct education on world outlook, outlook on life and values, and pay attention to cultivating students' humanistic spirit, so that every student can respect, love and cherish life and make flower of life bloom harmoniously.
