Construction Of The Democratic Outlook Of High School Chemistry Classroom Teaching Research

Traditional teaching ideas considered knowledge to be affirmative truth and regarded study as the infusion of knowledge from outside. However, these ideas underestimated learners' ability of cognition, knowledge, experience and differences. They also intended to show the over-simplicity in teaching. These traditional misleading ideas resulted in negativity. Therefore, the key point in reforming the traditional teaching is to refresh traditional teaching ideas and propel initiative, opening and effectiveness of teaching. Constructivism shows three important diversions, and emphasizes the construction, sociality and situations of leaning. It is of important significance to the reform of traditional ideas, the realization of initiative and effective teaching.,This article is divided into six parts. The first part refers to philosophic source of constructivism, physiology, basal biology and the development and diversion of contemporary constructivism, and elaborate the theory of constructivism. In the end, the author puts forward some own cognition of constructivism.The second part emphasizes the necessity and importance of the subject through questionnaires and analyses the results of them.The third part and the fourth part are the key parts of this article. The third part explains several key points which should be taken notice of under the instruction of constructivism in the design of teaching : effective teaching should stimulate student' initiative in learning and should keep interaction with students between teachers and students or students themselves; effective teaching should provide students with learning materials and the safeguard of time and space and should aim to make students understand their knowledge completely, and should pay attention to learners' and other's recollection; it should let students gain active experience and emotion as to this subject. The fourth part refers to how to use constructivism to instruct the teaching of chemistry combined with the real examples of teaching in chemistry classes. There are four examples: the properties of aluminum, the hydrolyzed of salt, the properties of cellulose, and the properties of ammonia.The fifth part is the recollection and conclusions to teaching examples.The last part is an appendix, including questionnaires and teaching materials.
