The Research On Teaching Strategies Of Original Chemistry Problems Based On The New Curriculum Standards

The cultivation of students' chemical discipline literacy is emphasized in the promulgation of the new curriculum standards(2017 edition),and teachers' in-depth thinking on teaching methods and teaching strategies are triggered.Among them,the original chemical problems play a good role in improving students' problem-solving ability,divergent thinking ability,abstract modeling ability and sense of social responsibility,which is in good agreement with the requirements of core quality of chemistry.However,the research on the teaching strategy of the original chemistry problem is seldom paid attention to and applied in the teaching practice.In this paper the concept and characteristics of the original chemical problems are analyzed,by questionnaire and personal interview,the questionnaires are distributed to students at different levels in internship school,evaluation criterion is made.According to the results of data analysis,and then through personal interview,it is concluded that high school students to solve the original chemical levels,combined with cognitive characteristics of students to propose the feasible teaching strategy,a reference for teachers' teaching is provided in the future.This paper is based on the basis of summarizing the research background,research purpose and significance,and the research status of original chemical problems at home and abroad,the research content and methods are put forward.The theoretical core of the original chemical problems,which includes the definition and theoretical basis of the original chemical problems are studied,like the requirements of constructivism theory,situational cognition theory,pragmatism theory and new curriculum standards.The characteristics of the original chemical problems,design principles and solutions as well as the advantages of the introduction of teaching are described.In the fourth part,by collecting and sorting out the data of the original test paper of chemical problems,the students' current level of problem solving are understood.The suitable teaching strategy is put forward.and the practice research is carried onaccording to the student present situation level,the teaching effect is analyzed.Through investigation and teaching practice,it is of practical value to introduce the original chemical problems into teaching based on core literacy,and it is helpful to explore appropriate teaching strategies for both teachers' teaching and students' learning.
