"Environmental protection, education-oriented." Organic infiltration of environmental education in mathematics teaching can transform environmental materials in textbooks into primary school students' environmental quality, which is conducive to primary school students to establish a good environmental concept, arouse potential environmental awareness, and cultivate primary school students' good environmental behavior, so that each of us can truly become an excellent environmental guardian and creator of a harmonious environment.
Below I combine my own teaching practice and talk about some superficial ideas on how to give full play to the advantages of mathematics textbooks and effectively infiltrate environmental education:
First, the existing teaching materials are processed, and the contents of the teaching materials are fully tapped for environmental education.
Although the primary school mathematics syllabus does not clearly stipulate the requirements of environmental education for primary school students, we will find that there are still many mathematics contents in mathematics textbooks that are related to the environment and closely related to people's production and life. We should make full use of the ready-made materials in mathematics textbooks, process them properly, seize the good opportunity and organically infiltrate environmental education. In particular, the new mathematics textbooks for primary schools are illustrated with pictures and texts, and more than 80% of the illustrations contain rich environmental education contents. For example, the following figure
Illustration 1: Understanding of "15" on pages 14 and15 in the first volume of Senior One, the picture shows animals taking a leisurely walk in the zoo. Students can learn about the animal world in nature by counting, and make them realize that they should cherish and care for wild animals. Illustration 2: "8" and "9" on page 53 of the first volume of senior one, in which a slogan "Love nature and protect the environment" is clearly written. Under the guidance of the teacher, the children are fertilizing and weeding the young trees and watering and loosening the soil for the flowers. Through counting teaching, students can love nature and cultivate their awareness of protecting biology.
Example 3: The second volume of Senior Two 109 page "Statistics" allows students to analyze the traffic of urban vehicles through statistics, so as to understand the exhaust pollution of vehicles, stimulate students' desire to protect the environment, and cultivate students' awareness of reducing pollution [this article is transferred from Feifei Curriculum Park. Net].
Illustration 4: Exercise on page 99 of the second volume of the second day of junior high school: The picture shows children planting trees and purposefully infiltrating the awareness of environmental greening through practice.
Due to the low level of understanding and limited knowledge of junior students, the content of environmental education in textbooks is mainly perceptual and intuitive. For example, in the fourth volume of the new textbook, there is an exercise: there are 1 166 species of birds found in China. With exquisite illustrations. This is a good opportunity to infiltrate and take care of birds. I asked the students to write down the numbers first, and then let them read. I realized that there are so many kinds of birds in China, and then I asked, "What birds do you already know? Who can tell me? " The students are very enthusiastic, and I praised them in time for caring about birds. But when I projected a report about killing birds, the children were excited and angry. They all condemned the hunters and complained about the birds. In this way, children not only consolidate reading and writing, but also have a strong sense of caring for birds.
By reasonably infiltrating environmental education into existing textbooks, students can not only learn to answer such questions, but also consciously help them understand the laws of nature, know that the environment has an extremely important relationship with human survival and development, and know that human beings have made unremitting efforts in the process of utilizing, protecting and transforming nature. In this way, students' awareness of environmental protection will be improved imperceptibly. It can also improve students' correct scientific understanding of the relationship between man and the surrounding environment, and realize that man is the son of nature and can't just regard man as the conqueror of nature. There is a fate and interdependence between man and the environment, so we should establish a new viewpoint of protecting the environment while making rational use of it, especially the consciousness of "sustainable development".
Second, broaden the mathematics classroom, connect with real life, and let students get environmental education in mathematics practice.
Environmental education can't just stay at the superficial level of understanding and publicity, but should be implemented in real life. It's not enough to take math class for 35 minutes to truly root environmental education in children's hearts. Therefore, we must also use other means, such as investigation, research-based learning and other mathematical practice activities, to infiltrate environmental education in the activities.
(A) to carry out "how green is my hometown" mathematical practice activities to cultivate students' awareness of caring for green [this article was transferred from FFKJ.Net, Feifei Curriculum Park] (3. 12).
In order to naturally and moderately infiltrate environmental education into teaching, I mainly dig out the permeable content from the application questions and find a suitable combination point to integrate into the teaching design. Carry out mathematical practice activities in combination with 3. 12 Arbor Day to let students know how green my hometown is. When doing activities, combined with some specific data of Shanghai's environmental greening area (including campus greening) in recent ten years, show corresponding videos and pictures, so that students can understand the harmonious relationship between people and the surrounding environment and the role of environmental protection while enjoying. So as to arouse students' awareness of "loving and protecting green". Find the right time to carry out "Why do you want to plant a lot of trees?" What are the benefits of it? "Research activities allow students to find relevant information and understand the benefits of afforestation: making oxygen, conserving water and soil, eliminating noise, purifying air and regulating climate.
Through practical activities, let students know that mathematics is closely related to scientific knowledge of environmental protection, and cultivate students to form a good habit of "loving and protecting green". So as to cultivate students' good habit of caring for flowers and trees from childhood and not picking flowers and plants, and cultivate students' good environmental morality of living in harmony with the environment.
(B) to carry out "water is the source of life" mathematical practice activities to cultivate students' awareness of water conservation (3.22)
Combined with China Water Week activities, carry out mathematical practice activities, let students find water resources information in China and write math diary. Educate students to start with small things around them and combine with the community to create a boutique community: after installing water-saving valves in a residential building, each household saves 2.5 tons of water on average every month. According to this calculation, how many tons of water can 54 households save in three months? Teaching combines with students' reality, and leads students to visit waterworks and sewage treatment plants before class, so that students can understand the hard-won water and the cost of wastewater treatment. Let the students discuss again: Why should this residential building be equipped with water-saving valves? Arouse students' thinking, a faucet that is not tightly turned off will drain several tons of water a month. These figures written around us should arouse our sufficient attention. Educate students to save water consciously in life. Don't turn on the tap too much when using water, and turn it off after using it. Learn to use more water, such as washing vegetables with rice washing water and watering flowers with vegetable washing water; Wipe the floor with laundry water, flush the toilet, etc. And form the habit of saving water.
(3) Carry out the mathematical practice of "I give a strategy for environmental protection" to cultivate students' awareness of pollution control and cleanliness.
Students deeply understand the importance and arduousness of environmental protection through practical actions that can be seen, heard and seen. At the same time, for some potential students who are willing to engage in environmental protection work in the future, they have created preliminary environmental protection cognitive conditions, so that they can organically combine knowledge, practice and responsibility, and encourage and guide them to join the environmental protection cause.
During the activity, in the campus, parks, streets and communities, let the students consciously carry out various "clean, tidy and beautiful" activities of "starting from me, starting from now, starting from the side and starting from small things" to publicize the significance of environmental protection to the surrounding classmates and parents. Everyone will support and actively participate in urban greening construction, so that everyone can become an "environmental citizen", strive to be an environmental guardian, and use their own.
Cultivating students' consciousness and ability to consciously participate in environmental protection activities can not be formed by one or two publicity and education or simply preaching and putting forward some environmental protection requirements. However, through various educational methods and repeated participation in practical activities, we can internalize our own environmental awareness and externalize it into environmental protection actions. So we try to combine environmental protection with mathematics in math class, so that environmental awareness can be injected into every child's mind.
