Research On The Teaching Of Four Representations Of Chemistry Based On SOLO Classification Theory

Due to the demand for education in the new era and the increasing maturity of modern digital handheld technology,in chemistry teaching,we should pay attention to cultivating students' quantitative thinking ability and promoting students' thinking development.The teaching mode based on solo classification theory can help students build chemical knowledge from macro,micro,symbol and curve angles,help teachers realize the integration of teaching evaluation and analyze the development degree of students' thinking.At present,there are few teaching cases that combine the quadruple representation with solo classification evaluation theory.Therefore,this thesis puts forward the teaching research of combining the quadruple representation teaching mode with solo classification evaluation theory,and discusses whether the students' thinking level has been developed through practical cases.Firstly,the current situation of teachers and students is investigated through questionnaires and interviews,and then the corresponding teaching methods are put forward according to the result analysis,the design ideas of teaching mode are constructed,and the teaching design of related topics of aluminum and its compounds and electrolytic cell is provided.At the same time,the practical research is carried out in two senior two classes of a senior middle school in Yingkou City,Liaoning Province.The test thesis compiled by solo classification theory are used for pre-test and post-test.Combined with the pre-test data and post-test data of the experimental class and the control class,the research conclusion is obtained and the existing shortcomings are analyzed by spssau software.Under the guidance of solo classification theory,the practical analysis is carried out by using the four representation teaching mode.It is found that the thinking level of the research object has been developed,especially at the two levels of relevance and expansion abstraction.At the same time,it also constructs the teaching design idea of the teaching mode to provide teachers with reference cases of the integration of teaching evaluation.However,there are still some defects in practice,and we hope to further explore its value in the future development.
