Research On The Application Of Thinking Visualization In Junior High School Chemistry Teaching

Since the 21st century,with the rapid development of the world and the continuous progress of science and technology,the social requirements for talents are not only satisfied with the mastery of knowledge and skills,but also pay more attention to the needs of personal thinking and quality.Visualization of thinking refers to the method and process of using a series of graphic techniques to clearly and visibly present the originally invisible thinking.According to 2022 our country compulsory education chemistry curriculum standard ",to the requirement of teaching junior high school chemistry class status and the role of visual thinking,design thinking visual teaching in junior middle school chemistry teaching,teaching strategies and application model,to promote the chemistry thinking teaching and improve students’ thinking ability to provide new ideas,realize the literacy class landing.The content of this paper is divided into three parts,respectively for the background and research status of thinking visualization review,thinking visualization applied in junior high school chemistry teaching strategy analysis,thinking visualization applied in junior high school chemistry teaching practice and evaluation feedback.The contents of each part are summarized as follows:The first part is the background and current situation of the subject.Through literature review,it is concluded that the research on visualization of thinking has been carried out earlier in foreign countries with a wide range of applications,while the research on visualization of thinking started late in China but the number has gradually increased in recent years,and most of the research simply interspersed with conventional teaching design,while only a few authors have paid attention to the inspiration and gradual cultivation of thinking.The second part through the analysis of the middle school students in the learning process of difficult knowledge,abstract concepts,thinking obstacles,put forward the thinking visualization in teaching application strategy :(1)thinking visualization applied to the construction of concept model;(2)Thinking visualization is applied to the formation of inquiry methods;(3)Visualization of thinking is applied to the sorting of problem solving ideas;(4)Visualization of thinking applied to the construction of knowledge network;(5)Visualization of thinking applied to the design of teachers’ teaching programs.Combined with the strategies,relevant models are designed to provide reference materials for visual teaching of thinking.Third part design the application of visualization in the teaching of thinking model,and according to the model design of the new teaching junior high school chemistry(atomic structure)and recitation(haining)and recitation(mixed solution integrated computation)three type of teaching design,teaching design and will be applied to the practice of teaching,learning assessment and teaching reflection,It provides a case reference for teachers to apply the thinking visualization teaching strategy.Based on theoretical and practical research,this paper draws the following conclusions :(1)visualization of thinking applied in concept and principle teaching can help students establish the connection between macroscopic phenomena and microscopic nature,understand and represent chemical changes,and improve the ability of model building and innovative thinking.(2)Visualization of thinking is applied in experimental inquiry class to help students establish clear and complete cognitive thinking,gradually form rigorous and scientific inquiry spirit and scientific attitude,and cultivate students’ evidential logical reasoning ability,scientific inquiry ability,scientific spirit and social responsibility.(3)Visualization of thinking is applied to exercise training classes to help students clarify their thinking,cultivate visual thinking,remove thinking obstacles,and enhance their confidence in the formation of ideas for difficult problems.
