Design Of High School Chemistry Teaching Activities Based On Knowledge Visual Resource

With the continuous deepening of educational informatization and the continuous development of educational technology field,the emergence of knowledge visualization resources provides a new idea for chemistry teaching.Nowadays,most of the knowledge in high school chemistry textbooks is presented in the form of two-dimensional plane,which is abstract and obscure.Only through the traditional chemistry teaching tools,students can not clearly understand it.In the long run,the development of their cognitive ability will be affected.Therefore,this study tries to explore whether the design of high school chemistry teaching activities based on knowledge visual resources can affect students' performance and cognitive ability,and can help students with chemistry learning.This study on the relevant literature at home and abroad,understand the shortcomings in the teaching situation based on knowledge visualization resources,in the existing teaching practice research,the use of knowledge visualization resources is single,most of the mind mapping,concept diagram,using mobile devices visual teaching research case is not rich,and the researchers of students' thinking and ability changes,only in the analysis of students performance changes,most of the practice results are only classroom observation method,no quantitative data analysis,its scientific is questionable.follow,This study is based on the theoretical basis of learning pyramid theory,visual learning of STILE model,and activity theory,Combining knowledge visuthe characteristics of the resource,The process of high school chemistry teaching activities based on knowledge visualization resources is constructed,In the case of specific teaching activities,Relevant teaching practice was conducted,To confirm whether the design of high school chemistry teaching activities based on knowledge visualization resources can be recognized by teachers and students and improve students' chemistry performance and cognitive ability,Using the methods of questionnaire survey and interview,The results show the feasibility of the high school chemistry teaching activities design based on knowledge visualization resources,Can change or even improve students' chemistry performance and cognitive abilities,Front-line teachers and learners are highly satisfied with the implementation of the activities,With a positive attitude,The popularity of the process is just around the corner.Finally,the author summarized and reflected on the whole research process,and hoped to add teacher exchange and study activities in various places,to truly promote the application of knowledge visualization resources in teaching activities.At the same time,we call on them to pay attention to the cultivation of students 'ability and the changes in students' thinking.At the same time,further prospects on the future research direction.
