Middle-School Chemistry Education In The Perspective Of Primitive Nature And Man-made Nature

By atoms and molecules, Chemistry discloses the mystery of primitive nature. And on the basis, Chemistry creates and develops a lot of man-made nature for people, thus greatly satisfying people's material demands in social production and living. However, with a lot of severe problems such as environmental pollution, lack of energy, and abusing of additives arising, the public hold many misunderstandings and anxiety. In view of the critical reality, I come up with the topic that middle-school Chemistry teaching should be conducted from the angle of primitive nature and man-made nature. I hope the thesis can help the students form a proper understanding about the relation between man and nature. Then they will realize the great role of Chemistry in society. Thus, I believe the students can understand and love science better.Based on the introduction of primitive nature and man-made nature, the thesis makes an analysis of the theory of primitive nature and man-made nature as well as the content in teaching structure. In this course, the thesis points that the students should form the basic knowledge on Chemistry. By strengthening the practice of experiments, the students make explorations on primitive nature; by mastering the transforming rules of materials, students try to create man-made nature. By carrying out green Chemical activities, we can deepen the students'understanding about man-made nature. In the highly speedy era for scientific development, it is especially important that Chemistry could combine with social productive technology. In the middle-school Chemistry, it is necessary to conduct the teaching on relations between primitive nature and man-made nature. In this way they could have an objective view on scientific technology and make the reasonable use of Chemical substances . Besides, applying the activity of exploring study, we can convert the students from their conventionally passive habit in study. Thus we can guide the students actively understand the relation between primitive nature and man-made nature. Then they can better know about Chemistry and form scientific values and views of materials.
