To Promote The Design And Teaching Of "Sulfur Transformation" Experimental Activities For The Core Accomplishment Of Chemistry

The education policy of "lide shuren" issued by the ministry of education aims to cultivate all-round development people with core qualities.Chemistry discipline core quality is put forward from the Angle of chemical subject core literacy,to promote the development of students' chemistry education ultimate goal is to enable students to master knowledge,develop ability,cultivate moral character,and can focus on social issues,participate in solving social problems,social awareness,enhance the social sense of responsibility,can effectively carry out the "setting up virtuous persons"" the education policy of the demands for minors.It is of positive practical significance to study the application of core accomplishment of chemistry in middle school chemistry teaching,especially in chemistry experiment teaching.This paper takes the experimental teaching of "transformation of sulfur" as the main research object.On the one hand,it provides teaching ideas for implementing the core accomplishment of chemistry in the experimental teaching of "transformation of sulfur" by combing the research on the teaching of core accomplishment of chemistry.On the other hand,by summarizing the present situation of "transformation of sulfur" experimental teaching,it provides the foundation for carrying out "transformation of sulfur" experimental teaching.The purpose of this research is to solve the practical problem of how to implement the core accomplishment of the subject in experimental teaching.Taking the core accomplishment of chemistry as the theoretical basis for the research,the experimental teaching design idea based on the core accomplishment of chemistry was firstly established,which was mainly divided into five parts :(1)the subject content was analyzed to clarify the core accomplishment of chemistry.(2)reasonably arrange teaching contents around core knowledge;(3)combining with the theme,choose real situation materials with growing points;(4)set inquiry activities to cultivate the consciousness of scientific inquiry and innovation;Among them,inquiry activities are divided into five parts: raising questions,forming hypotheses,making plans,collecting evidence and drawing conclusions;(5)apply scientific methods to master knowledge and improve ability.According to the experimental teaching design idea,the experimental teaching design of "sulfur transformation" is designed.The research mainly adopts the quasi-experimental research method to carry out the "sulfur transformation" experimental teaching based on the core accomplishment of the chemistry discipline in the experimental group,and the students in the control group learn according tothe teaching of the natural state of the school.After the teaching,the students in the experimental group and the control group were tested with a self-designed questionnaire,and the students in the experimental group and the chemistry teachers in the school were interviewed to understand the implementation of the discipline core literacy in the experimental teaching.Through the analysis of the results,the following conclusions are drawn: the students believe that the experimental teaching based on the core accomplishment of chemistry is helpful for their learning,and most of them like the experimental teaching of this class very much.This experimental teaching effectively promoted the cultivation of students' core qualities in chemistry,especially in the three aspects of "changing concepts and balancing thoughts","scientific inquiry and innovation consciousness","scientific attitude and social responsibility".Although students fully participate in all aspects of experimental teaching,which is more effective for training their thinking ability and operational ability,students' ability to flexibly use knowledge to solve practical problems is not very strong.It is suggested that teachers should clarify and apply the concepts and ideas in teaching,which will be more helpful for students to understand.Teachers should consciously connect knowledge with actual production and life to guide students to pay attention to social problems.
