【摘要】：当今社会,工业企业竞争激烈,发展迅速,越来越严重的环境污染问题对人类的生存产生了威胁,人们开始重视环境污染问题。如何从根本上消除环境污染呢?这个问题迫在眉睫。作为社会的成员,我们都应该保护环境。这是我们的责任,也是我们的义务。中学阶段是人的思想意识成熟的关键阶段。初中化学与环境问题联系紧密,在初中化学中对学生进行环境教育,可以让学生了解环境污染产生的原因、危害和治理措施,使学生将理论知识和日常生活相联系,从点滴小事做起,树立可持续发展观和环保意识。在教学中,通过多种途径进行环境保护教育,使学生在学习的过程中形成环保意识。本研究选取天津市佟楼中学2015级初三(3)班和(5)班的学生为研究对象,(3)班作为对照班,(5)班作为实验班。根据本校学生的实际情况,结合人教版九年级化学教材,通过研究义务教育课程标准和教材,寻找教材中与环境教育有关的知识点,以此作为切入点进行相应的教学设计,对在课堂教学中、化学实验中、综合活动中进行环境教育的实践研究。通过研究表明,在本校化学教学中适当进行环境教育获得了较好的成效。本校学生习惯较差,随地乱扔废物、破坏环境的现象普遍。通过在实验班进行环境教育,学生的不良行为习惯有所改善,例如看到垃圾学生能主动去捡,在教室中能做到随手关灯节约用电。经过六个多月的教学实践,学生学习化学的兴趣浓厚、热情高涨,已初步形成了环保意识,能在生活中关注环保知识并会运用所学知识解决一些简单的问题,动手和沟通能力也得到了提高。
[Abstract]:Nowadays, with the fierce competition and rapid development of industrial enterprises, more and more serious environmental pollution problems threaten the survival of human beings. People begin to attach importance to environmental pollution problems. How can we fundamentally eliminate environmental pollution? The problem is imminent. As members of society, we should all protect the environment. This is our responsibility and our duty. The middle school stage is the key stage of people's ideological maturity. Junior high school chemistry is closely related to environmental problems. In junior high school chemistry, the students can be taught about the causes of environmental pollution, hazards and management measures, so that students can connect their theoretical knowledge with their daily life. From little things, set up the concept of sustainable development and awareness of environmental protection. In the course of teaching, environmental protection education is carried out through various ways so that students can form environmental protection consciousness in the course of study. Class 3 (3) and Class 5 (5) of Grade 2015 of Tonglou Middle School in Tianjin were selected as the research objects, class 3 as control class and class 5 as experimental class. According to the actual situation of the students in our school, combined with the chemistry textbook of Grade 9, by studying the curriculum standard and teaching material of compulsory education, we can find out the knowledge points related to the environmental education in the teaching material, and take this as the starting point to carry on the corresponding teaching design. This paper studies the practice of environmental education in classroom teaching, chemistry experiment and comprehensive activities. The results show that proper environmental education in chemistry teaching in our school has achieved good results. This school student habit is poor, littering everywhere, the phenomenon that damages the environment is common. Through environmental education in the experimental class, students' bad behavior habits have been improved, such as seeing that garbage students can take the initiative to pick up, and to save electricity by turning off lights casually in the classroom. After more than six months of teaching practice, students have a strong interest and enthusiasm in learning chemistry. They have initially formed a sense of environmental protection. They can pay attention to environmental protection knowledge in their daily lives and will use what they have learned to solve some simple problems. Hands-on and communication skills have also been improved.
