Study On The Modeling Ability Of High School Students'chemistry Knowledge Based Based On Problem Form

Chemical modeling is an important method to study the law of chemistry and explore the scientific world,and it is also an important research object of chemistry.As an important scientific method,modeling is very important for chemistry study,and there are some requirements for students' ability to study chemistry modeling in the current outline of chemistry examination in China.The improvement of modeling ability in chemistry problem solving of senior high school students is an important content of implementing the new curriculum chemistry course goal to cultivate students' ability to solve practical problems related to chemistry.Teaching students about chemical modeling in chemistry teaching can not only enhance their understanding and understanding of chemistry knowledge,but also help them to learn Students understand and apply scientific methods to improve students' chemical science literacy.Based on literature research,this paper makes a descriptive analysis of chemical modeling ability and problem form,and constructs a psychological model of students' chemical modeling ability based on problem form.Based on theoretical research,the evaluation criteria of chemical modeling ability based on problem form model are constructed,and the original battery problem form is selected as the test evaluation model,investigates and analyzes the practice of chemistry modeling ability of senior three students in a middle school,and puts forward the corresponding teaching strategy according to the conclusion of the investigation.It can be seen from literature research that although the cognitive models of chemical modeling and chemical models in recent years And study and teaching related research is a hot topic in academic circles,but the research on modeling ability of high school students' chemical knowledge based on problem form is rarely reported in literature.This paper evaluates the chemistry modeling ability of high school students through the problem form model,and puts forward the corresponding teaching strategies through practical investigation and analysis,which is a useful attempt and extended work to effectively cultivate students' chemistry modeling ability and improve students' problem-solving ability.
