Research On Improvements Of High School Chemistry Demonstration Experiments In PEP Edition Compulsory Textbooks

The current social and economic development of our country is entering a critical "deep water" and "hard time". How to break the troubles, realize the adjustment of industrial structure and major shift in the way of economic growth, and realize the dream of the great powers, there must be reform and innovation spirit, which attaches great importance to science and technology and education, relying on science and technology and innovation to promote the sustainable and healthy development of the society. While the development of science and technology cannot leave the talents, especially how to cultivate creative ability, and who can lead the social development of all kinds of talents is particularly urgent and important.Under the background of the current education reform, as an important basic subject, chemistry has always played an important role in training high-quality and innovative personnel. While chemical experiment, especially classroom demonstration experiment is the important tool of teachers’ teaching and students’ learning, which can greatly improve the efficiency of classroom teaching, promote the cultivation of students’ innovative thinking ability and innovation ability.This paper mainly use two methods of questionnaire and interview to investigate the chemistry classroom demonstration experiment condition in current high school, analyze the results of the questionnaire and teacher interview to obtain information, and find out the problems existing in the classroom demonstration experiment in current high school chemistry experiment teaching, optimize and improve the teaching demonstration experiment to solve these problems; in that paper we select high school chemistry compulsory teaching demonstration experiment improvement typical case from the open literature, to analyze research and summing up the basic idea of experimental improvement, methods and skills, and gradually built up for different types of experiment to improve the research of the basic patterns, so as to provide the study and reference guide experience; according to the experiment basic principle and the constructivism learning theory, theory of subjectivity education and innovation education theory as the main guiding ideology, aim at the problem exists in the compulsory textbook for classroom demonstration experiment itself, intend to improve the success rate of experiments through simplification and life improvement, simplified operation, easy to observe and the purpose of improving the efficiency of experiment teaching. In addition, through the experiment improvement process also can prompt the chemistry teacher to deep understanding research, integration and innovation of chemical knowledge and related chemical experiment, so as to promote the teachers from the knowledge-base to research type.This paper is divided into five parts to discuss the new curriculum under the background of high school chemistry demonstration experiment research. The first part: the research background, purpose, significance and methods. The second part: the theoretical basis. The third part: the questionnaires and interviews. The fourth part: demonstration experiment improvement exact case. The fifth part: the results and prospect.
