Empirical Research On Problem System Design Of Chemistry Teaching In Senior Grade One

Under the background of the new curriculum reform,the author combed the relevant research results of chemistry teaching problems both at home and abroad.In this study,the author takes the theory of teaching strategy and constructivism as the theoretical basis.According to the cognitive level of the students,the characteristics of the chemistry and the principle of problem design,the author combines the theory of systematic design of teaching problems with the high school chemistry teaching,and constructs a model for the design of teaching problems suitable for high school chemistry class.After that,the author wrote relevant teaching cases on the basis of this teaching model.Taking advantage of the opportunity of teaching practice at the stage of postgraduate education,we carry out a practical research on the design model of classroom teaching problems.Through the two tests in the experimental class and the control class,and by using the self compiled questionnaire,the author studied the effect of the system design on the students’ academic achievement,the interest of chemistry and the ability of thinking.This article can be divided into six parts:The first part is the introduction.Including the research background,domestic and foreign research status,research significance and research methods;The second part is the theoretical overview of the system design of chemistry teaching problems in senior grade one,including the definition of core concepts and the support of basic theory;The third part constructs the design model of chemistry teaching problem in senior grade one from the aspects of chemistry subject characteristics,teaching problem evaluation,teaching strategy and teaching process design,which lays a foundation for teaching practice;The fourth part takes the two parallel classes as the control class and the experimental class,and implements the design model of chemistry teaching problems in the experimental class.A questionnaire survey was conducted and the results were compared before and after.SPSS software was used to carry out statistical analysis;The fifth part analyzes the application effect,innovation and deficiency of the system design of chemistry teaching problem in senior grade one;The sixth part is the author’s suggestions and prospects for further research on the system design of chemistry teaching problems in senior grade one.
