Research On Characterization And Application Of The Effectiveness Of Primitive System In Chemical Classroom Teaching

Since the implementation of new curriculum reform in basic education,effective classroom became the most important pursue of landing the idea and target of new curriculum reform.Various chemistry educators and practitioners took high attention on how to teach effectively.The issue of effective classroom essentially belongs to the effectiveness of classroom teaching,such as what is effectiveness? How to represent effectiveness? How to evaluate the effectiveness of classroom teaching? Thus,those research topics are urgently need to be solved.Different perspectives can be held for studying the effectiveness of classroom teaching,such as student perspective,teacher perspective,the perspective of teaching cognition and the perspective of teaching content.Those perspectives can uncover the characteristics and roles of the effectiveness of classroom teaching through different reasonable ways,and thus,it is so important that taking a holistic perspective to know the effectiveness of classroom teaching.Underpin previous studies of other researchers and our own previous works,this paper mainly discloses the nature and features of the effectiveness of classroom teaching using a microcosmic perspective,and further to represent and evaluate the effectiveness of classroom teaching.The main structure and chapters are listed as follow:The qualitative representation of the effectiveness of primitive system.Through reviewing previous articles and focus group interview(include expert teachers and education researchers),I employed item analysis to develop a reliable and valid evaluate scale to assess the effectiveness of primitive system,and further used EFA and CFA to extract 5 main factors affecting the effectiveness of primitive system,there are the rationality of using time,the quality of instructional behavior chain,matching degree,the quality of using resources and technology,and the rationality of primitive content.The quantitative representation of the effectiveness of primitive system.Using regression analysis,this study found that the quality of instructional behavior chain is the most important factor affecting the effectiveness of primitive system.Thus,the quantitative representation model of effectiveness of primitive system was constructed.The level representation of the effectiveness of primitive system.Through cluster analysis and discriminant analysis,this paper found the high,mediate and low effective levels of primitive systems,and analyzed the features and the reasons of level variations.The comparative evaluation of the effectiveness of primitive system.Using above instruments,from the perspective of the effectiveness of primitive system,this paper compared the differences between teacher gender,teacher PD stage,lesson category and content themes,and discussed the reasons why these differences exist.
