A Research On The Instructional Strategy Of Infiltrating Environmental Education In The Teaching Of Chemistry For Normal School

Mankind society has gained brilliant civilization through a history of thousands of years and meanwhile it is also facing the threaten of the world population, health, grain, energy sources, natural resources and so on. Under such circumstance, infiltration of environmental education may let students understand these circumstances and probably brings about serious consequence. It makes them produce the feeling of impending crisis and the sense of urgency, moreover it fosters studentsto concern about the responsibility of mankind's existence and development, and makes them become the citizens which possess good mentality and behavior of environmental protection. Thus, it promotes the sustainable development of mankind's existence and society.Through the deep study of the theories of constructivism, green chemistry and sustainable development ,we find that these three theories are intimately related .Constructivism learning theory considered "context", "cooperation", "conversation", and "meaning construction" as the four basic factors of leaning environment. Constructivism emphasized that students gain knowledge, mastery of skill, manners and method by means of students' subjective learning and initiative construction of the meaning of a thing on the base of subjectivity and investigation. And the goal of green chemistry is that we develop the behavior and consciousness which students spontaneously prevent pollution. In essence, the theory of sustainable development is to promote the harmoniousness of mankind and nature. Green chemistry is an important way to realize sustainable development. In order to attain the aim of the mentality of environmental protection and the ability of environmental protection, we carry out the meaning construction on the knowledge of infiltrating environmental education through the design of the context on environmental problem, students' subjective and learning throughpractice on the base of subjective investigation and cooperative-learning. In this way, it is beneficial not only to attain of students' knowledge, but also to the improvement of their mentality of environmental protection and their behavior of environmental protection, and this will set up the ideas of sustainable development. But in the former studies theory and practice in infiltrating environmental education in chemistry teaching for normal school, the studies on how to comprehensively apply constructivism theory, theory on green chemistry and the theory of sustainable development to the chemistry teaching of infiltrating education are seldom concerned. With this purpose, we construct the teaching principles and teaching strategies of infiltrating environmental education on the base of these three theories, so as to improve the mentality of environmental protection and the ability of the experimental design on green chemistry by following the teaching principles of infiltrating environmental education and utilization of good teaching strategy of infiltrating environmental education .Having carefully studied theories of constructivism theory, theory on green chemistry and theory of sustainable development, we propose the teaching principles and teaching strategies of infiltrating environmental education in chemistry teaching for normal school. With class 8, Grade 2,HuPu normal school as the experimental class, weconstructed experimental study, and the same grade 's class 9 as the correlation class. In chemistry teaching of the experimental class, we utilized the teaching principles and teaching of infiltrating environmental education .For example: Principle of Experiment on Green Chemistry; Principle of Subjective Feeling and Learning Through Practice; Principle of Combining Structure of Environmental Protection (Surroundings) with Cognition Structure (Experience); Principle of Combining School-based Curriculum on Environmental Education with National Curriculum; Principle of Combining Teacher-training with Demonstration; Practice Principle; Strategy of Infiltrating Environm...
