Research On The Evaluation And Promotion Strategy Of High School Students' Chemical Thinking Modeling Ability

Thinking modeling is an important cognitive tool and scientific thinking method.It can not only help students better understand how to acquire knowledge,abstract concepts,and how to clarify the origin and context of laws and principles,explore the essence of phenomena from the outside to the inside in the exploration experiment,and finally come to a conclusion.It can also help students' attitude,interest,thinking mode and habit,knowledge mastery degree,chemical achievement,chemical knowledge development and transfer ability The improvement and promotion of the ability of ability,thinking ability and problem solving ability has an important impact.In a word,thinking modeling is of great significance to chemistry teaching.In the current chemistry teaching,there are still many teachers who only pay attention to imparting knowledge and lack of guidance and emphasis on thinking methods,and the related chemical research is not perfect.Middle school students are in an important period of thinking ability development.If they can't use scientific thinking methods and just passively absorb knowledge,they will not be able to learn and use flexibly and really improve their comprehensive quality.This study takes the important thinking method of thinking modeling as the research object,takes constructivism learning theory,cognitive learning theory,problem-solving theory as the theoretical basis,defines the concepts of thinking,model and thinking model,thinking modeling,chemical thinking modeling ability.The questionnaire method was used to investigate students' cognition and application of thinking modeling in chemistry teaching,and then a scale was constructed to evaluate the ability of senior high school students' chemical thinking modeling,and the existing problems were analyzed.Combined with the characteristics of the new curriculum standard,core literacy,discipline characteristics and college entrance examination proposition of chemistry,with the help of the research conclusion and experience of thinking modeling at home and abroad,the paper puts forward some suggestions Corresponding teaching suggestions and thinking modeling ability promotion strategy.The details are as follows:We found that:? the results of the questionnaire survey show that most students have little understanding and application of thinking modeling,and lack of systematic guidance.However,many students still hold a positive attitude towards the role and significance of thinking modeling,and express that they are looking forward to the teaching method of integrating thinking modeling.?the survey results of thinking modeling ability show that although some students can skillfully use the form of schema,frame diagram and mind map to sort out conceptual knowledge,most students think independently for chemical knowledge points At the same time,most students lack the ability of analysis and re cognition for some situations with cognitive conflict,and their thinking is not clear enough and lack of reflection and regulation.? to improve students' thinking modeling ability,teachers and students need to work together to create a positive and active classroom atmosphere,provide necessary scientific guidance and necessary cognitive framework to guide students to build The strategy of "wrong question book" can improve the enthusiasm of students' participation,and finally improve their thinking modeling ability.
