| In this study,the combination of experimental safety and chemistry teaching is used to explore the existing safety education theory of chemical experiment,and to explain the meanings of chemical experiment safety and osmotic teaching.It also analyzes the hidden dangers and avoidance methods of experimental teaching in high school(compulsory).Selecting the typical experiment as the teaching content,according to the principles of penetration of experimental safety awareness,it designs the teaching activities about penetration of experimental safety awareness and in the classroom teaching using "5E learning circle" as a teaching model for practical research.After the feedback and evaluation of the effectiveness of practice,it provides the ways and strategies of penetrating experimental safety awareness when teachers teach chemistry in high school.Through the chemistry education of penetrating experimental safety awareness in high school,this paper aims to gradually develop and strengthen the students’ experimental safety awareness and enhance students’ experimental safety literacy,so that students have a certain degree of self-protection,and the middle school chemistry teachers can be given a reference when teaching for penetrating the experimental safety awareness.This paper is divided into five parts:Part I:Introduction.Through the analysis of the contents of experimental safety awareness in high school chemistry curriculum standard,the contents of experimental safety awareness in high school chemistry textbook and the present situation of safety teaching in high school chemistry experiment,the research question is put forward.And the research significance,method and ideas are expounded.Part II:Research summary and related theory.This part mainly elaborates the research situation and the theoretical basis of the safety education of chemistry experiment in senior high school at home and abroad,and defines the core concepts.Part III:Construction of teaching activities of safety awareness in high school chemistry penetration experiment.This paper analyzes the hidden dangers and avoidance methods of experimental teaching in high school(compulsory)teaching,and systematically constructs the principles,teaching model and implementation process of infiltrating experiment safety awareness in high school chemistry teaching.Part IV:The instructions and practice of teaching activities of penetrating chemical safety awareness in senior high school.the investigation are determined and this part analyzes the present situation of experimental safety awareness of the objects of study through the research,designs teaching activities of penetration of experimental safety awareness for practical research and puts forward the ways and strategies of infiltrating the safety awareness of chemistry in high school chemistry teaching based on the evaluation of the implementation effect.Part V:Findings and prospects.Summarize the research results and make recommendations on the shortcomings. |
