A Study On The Improvement Of Freeman Scale For Chemistry Classroom

Study on the chemistry teachers’ classroom teaching behavior can be conducive to optimizing the classroom teaching of Chemistry,and promote chemistry teachers’ professional development.Quantitative research has the advantages of strong objectivity, good intuition, good scientific,etc,so,it has great significance for the development of ideal tool on classroom teaching behavior of quantitative research.This paper is divided into the following sections:The first part, introduce the research aim and meaning.The second part, summarize the research contents and methods of classroom teaching behavior at home and abroad.The third part, introduce the Flanders Interaction Analysis System (FIAS).The fourth part, combine with the current situation of the application of FIAS in the research of chemical teaching in our country,and find the original FIAS deficiency of the current chemistry classroom teaching behavior research in our country;Integrate domestic existing improvements,and analysis their advantages and disadvantages one by one;Find a breakthrough to improve the research,and present the analysis system--3C-FIAS based on contemporary chemistry classroom.The fifth part, through the application of normal chemistry classroom teaching video analysis and the teachers’ interview,investigate the applicability of the 3C-FIAS system, the practicability and scientific of the 3C-FIAS system.The sixth part, form the conclusions of the research.The research found:1.The original FIAS originated in twentieth Century sixty or seventy years in the United States, for a certain lack of chemistry classroom teaching behavior research in present China.2.Existing improvements has the problems of classification of chemical classroom teaching behavior is not comprehensive and far more code numbers.3.In this paper, the improved 3C-FIAS system as a quantitative tool in our country current chemistry classroom teaching behavior research, has certain reliability and rationality.
