Research On Teaching Design Of 'Electrolyte' Based On Thinking Modeling

"Electrolyte" is an important concept in middle school chemistry,with the role of connecting the preceding and the following,but the concept is abstract,and there are many related concepts,students have some difficulties in understanding,easy to confuse.Thinking modeling is an effective theoretical method of teaching and evaluation in teaching.It helps students to form a systematic knowledge system by constructing thinking model,so as to help students grasp the connection between concepts,deepen their understanding of concepts,improve their thinking ability and problem-solving ability,and is applicable to the teaching of "electrolyte".Therefore,this study carried out teaching research on electrolytes based on thinking modeling.Based on the literature review of thinking modeling theory and "electrolyte" teaching design research,this paper defines the core concepts,analyzes the relevant theoretical basis,and puts forward the general thinking of chemical teaching design based on thinking modeling.In this study,thinking modeling is to establish a thinking model of internal thinking through thinking mapping and other thinking modeling tools,so as to make the complex and implicit thinking explicit and simple,,which is conducive to students' construction of scientific and systematic knowledge.The general idea of chemistry teaching design based on thinking modeling is: "constructing ideal thinking model-guiding thinking model-applying thinking model-perfecting thinking model".On this basis,the teaching design of "electrolyte" section is made and the teaching practice is studied.Through the implementation of different teaching cases in the experimental class and the control class,and then the same post-test survey,the use of SPSS software quantitative comparative analysis of the experimental class and control class teaching effect.According to the result of theory research and practice research,found that thinking model can not only enhance the students' understanding of concepts,to help students overcome the isomerization of thought,to improve students' score in chemistry,can also help students to master the methods of thinking model,and established a complete system of knowledge and scientific and efficient way of thinking,so as to enhance the capacity and the ability of problem solving and thinking in chemistry teaching for thinking model construct the method is effective.This paper is mainly divided into the following eight parts:The first part: from the importance of the content of "electrolyte" and the effectiveness of thinking modeling explained the reason to choose this topic.Part two: the literature of thinking modeling theory and research on "electrolyte" instructional design is reviewed.On the basis of clarifying their views and research status,the direction of this research is found through analysis and summary.The third part: explains the purpose,task and method of the research.Part four: theoretical basis.The core concepts are defined,the relevant theoretical basis is expounded,and the theoretical basis of this research is explained.The fifth part: expounds the general idea of chemical teaching design based on thinking modeling.Part six: according to the above ideas,this paper analyzes the curriculum standards,textbooks and students related to "electrolyte" content,puts forward the teaching objectives,designs the thinking model expected students to construct,and designs the specific teaching links based on this,completes the teaching design of the electrolytes class.The seventh part: teaching practice research.The control class and the experimental class were set up for different teaching,and the teaching effect was tested with post-test questions,and the data was analyzed with SPSS software.The eighth part: summarizes the conclusion of this study,and puts forward the shortcomings of this study.
