Research On The Teaching Strategies Of The Knowledge Of Element Compounds Integrating The Nature Of Science In Senior High School

At present,countries all over the world attach great importance to the understanding of the nature of science when they reform the curriculum,and regard it as the key content of students’ scientific literacy cultivation.China also attaches importance to the cultivation of students’ concept of scientific essence.In 2006,the Chinese government specially focused on the cultivation of the scientific quality of the whole people(2006-2010-2020).After that,in 2011 and 2017,the "understanding of the nature of science" was conducted respectively The meaning of the paper is explained.However,the status quo of education on the nature of Science in China is not optimistic.Through reading a large number of literature,the author combs the research status of the nature of science,and finds that the knowledge of elements and compounds is an important part of high school chemistry,but no researcher has systematically studied it with the nature of science Teaching strategies of compound knowledge.What is the connotation of the essence of science?Can the teaching strategies proposed in this study help students to understand the nature of science effectively?And can the teaching of element compound knowledge with the essence of science help students better learn the knowledge of element compounds?In this paper,we found that after the teaching of element compound knowledge,the understanding level of students in experimental class and control class were improved,but the improvement of experimental class was more obvious,and the mastery degree of element compound knowledge in experimental class was obviously better than that in control class,so the teaching strategies of "integrating chemical history","scientific inquiry+reflection" and "dominance" teaching can be used The study also found that the learning of element and compound knowledge can not significantly improve students’ understanding of "the difference between theory and law".This paper mainly includes the following five aspects:the first chapter analyzes the current education policy,summarizes the teaching situation of element compound knowledge and the research situation of the nature of science,and clarifies the purpose,significance,research methods and ideas of this study.The second chapter is literature review,which mainly combs and summarizes the interpretation of the essence of science.The connotation of the essence of science defined in this study and the teaching strategy of element and compound knowledge integrating the essence of science are put forward.The third chapter is the research design of this study.Two parallel classes of senior one are selected as samples,and comparative teaching is carried out for the students of these two classes.Before and after teaching,the questionnaire of scientific essence view of senior high school students is distributed and the special test of element compounds is carried out.In the fourth chapter,SPSS 23.0 is used to analyze the results.The fifth chapter is the conclusion,enlightenment,innovation and deficiency of this study.
