Application Of Knowledge Visualization In Senior One Chemistry Teaching

Under the background of the new curriculum standard,the quality-based teaching was the basic requirement of the new curriculum standard.Among them,it paid attention to the structuralization and dominance of ideas,and required more systematic and comprehensive knowledge learning and understanding.To study the dialectical means of knowledge and the new classroom teaching mode,in a sense,it can help students form the logical combing of conceptual knowledge,the structure of chapter knowledge network,and the cultivation of students' autonomous learning,which was an urgent subject to be studied.In this study,the first compulsory course of chemistry in Senior One was chosen as the research content,and the application of knowledge visualization in the second chapter of compulsory course 1,the classification of substances,the redox reaction and the application of several important metal compounds in the third chapter were mainly discussed.This paper mainly used mind mapping and concept mapping to represent knowledge visually.By selecting two classes,one experimental class and one comparing class,the knowledge visualization teaching was adopted in the experimental class,which mainly includes the new teaching of knowledge visualization by teachers and the learning of students applying knowledge visualization tools independently after class.The routine teaching was adopted in the experimental class,through the questionnaire investigation,the interview notes and the academic achievement analysis,which explored the knowledge visualization tool in the high school chemistry application process to optimizes the student knowledge structure pattern,and helped students to establish chemical knowledge network and knowledge visualization tools,and improved students' autonomous learning ability.The results showed that knowledge visualization is helpful for students to construct knowledge and improve their autonomous learning ability.
