The Research On Visualization Teaching Strategy Of Declarative Knowledge In Grade Nine

Based on the new curriculum requirements and the rapid development of information media technology,this study organically combines declarative knowledge with visualization.On the basis of explaining the corresponding theoretical basis and analyzing the characteristics and functions of the chemical declarative knowledge and visualization methods,the chemical declarative knowledge and visualization methods are subdivided,and the visual teaching strategies adapted to different types of chemical declarative knowledge are proposed.By selecting and designing typical cases of various kinds of knowledge,the proposed visual teaching strategy is applied to the practical teaching process,which aims to help students to understand and apply knowledge easily and efficiently,and to build a knowledge system independently.In addition,the teachers not only widen the students' ideas and horizons by means of diversified information technology,but also develop students' innovative ability,cultivate students' scientific literacy,and realize the all-round development of students' morality,intelligence,body and beauty.This paper will be divided into five parts:The first part:introduction.By interpreting the requirements of the new curriculum standard for the classified teaching of chemistry knowledge in grade nine,combined with the influence of knowledge visualization theory on teaching activities,the research background,research purpose and significance,research methods and research ideas are expounded.The second part:Research Review and related theories.This paper mainly expounds the research status of "knowledge visualization" at home and abroad,defines the relevant core concepts,and gives a brief overview of the theoretical basis for guiding this study.The third part:the theoretical construction of visual teaching strategy of declarative knowledge in grade nine.The types,characteristics and functions of declarative knowledge and visualization methods are analyzed and summarized,and a visualization teaching strategy for each type of knowledge is proposed.The fourth part:the practice research of nine year chemistry declarative knowledge visualization teaching strategy.The representative content of three types of knowledge contained in chemical declarative knowledge is selected.And teaching design and practice are also carried out according to the corresponding visualization teaching strategies proposed in this paper.Through the design of after-school knowledge test and questionnaire survey,the implementation effect is analyzed.The fifth part:the research summary and the suggestion.A summary of the research is made,the problems in practice teaching are reconsidered and some suggestions are put forward.
