课堂教学中如何培养学生化学学科的核心素养——以霞浦七中为例

AbstractThe purpose of this study is to improve the quality of teaching,to improve thestudents'chemical core literacy,on the basis of explaining the concept of chemicalcore literacy in detail,taking the "direction,limit and rate of chemical reaction"as anexample,the paper investigates the satisfaction of students and front-line teacherswith chemical core literacy through interviews and questionnaires,so as to make sidereactions Whether the policy is valid.By analyzing the problems in teaching materialsand students'learning in the past,this paper puts forward four strategies:modelintuitive teaching strategy,thought map teaching strategy,practical teaching strategyand learning motivation teaching strategy,and integrates these teaching strategies intothe teaching design of "the direction,limit and rate of chemical reaction",and carriesout classroom practice after class After reflection,some suggestions are put forward.By comparing the unit test results of the experimental class and the control class,thepaper concludes that the strategy of cultivating chemical core literacy proposed by theauthor can effectively help students master the knowledge points of this chapter andimprove their scores.Through the questionnaire data,it is obvious that most of thestudents are satisfied with this new and dynamic strategy of cultivating chemistry coreliteracy.The results of the instructor interview show that the strategies proposed bythe author can make up for the shortcomings of the traditional old classroom to acertain extent.The results of the interview show that the strategy can have a positiveimpact on students'interest in learning and is conducive to the overall development ofstudents.Generally speaking,students'learning difficulties have been solved,andthey have the ability of independent learning,the interest of learning and the corequality of chemistry.Key words:Chemistry;classroom teaching;core literacy
