Awareness Of High School Chemistry Applications

Since the mid-20th century, the rapid development of the human society has made applied chemistry and the application of chemistry unprecedented highly developed. With Chemicals into each subject and almost every corner of life, more and more people have clearly realized that society will not develop without chemicals. As a natural science, and an important tool for promoting scientific development, chemistry plays an irreplaceable role in the history of human development, and will in the future play a greater role in social development. When studying chemistry, students should not merely grasp it theoretically, and they should learn to put it into use. In recent years, because of the influence of"examination-oriented education","The sea tactics",for many years ,has made chemistry a tool for students to meet the college entrance examination, and also for a high score in the examination. However, once the chemical knowledge is involved in practical issues, students are at a loss, which reflects the negative influence brought by students'study of pure chemistry knowledge: they study it merely theoretically without awareness of application. Students do not even know how to solve practical problems with chemical knowledge they learned, let alone the use of chemical ideas and methods in the collection of information, analysis of issues and solution of issues. Students are weak in the application of chemistry, which has become the biggest failure in the chemistry teaching in high school nowadays.The thesis is divided into six parts, including the proposal of the problem, the theoretical basis of research, the study of theoretical concepts, the contents of cultivating awareness of application, teaching practice, research results and reflection. On the basis of STS education theory, Tao Kingship's combination of Teaching perspective, Dewey's pragmatism theory, the author aims to construct a conception of cultivating awareness of application in senior High Chemistry Teaching, involving principles and ways of cultivating awareness of application, based on practical principle, scene principle, the principle of openness and adaptability, through the classroom teaching method, reading guidance law, media-based applications, network quiry lectures law, research learning and other ways to cultivate the five kinds of awareness of application:(1) The world is material; (2) chemistry is useful;(3) the development and rational use of energy; (4) Green Chemistry awareness; (5) chemistry can create new...
