Comparative Study On Safety Education Materials In High School Chemistry Textbook

The Guidelines for National Safety Education in Primary and Secondary Schools and the Guidelines for Teaching Materials of Life Safety and Health Education in Primary and Secondary Schools put forward clear requirements for national safety education,life safety and health education in chemistry curriculum,which have guiding significance for the implementation of chemical safety education and are also the evaluation basis for chemistry curriculum,textbooks and teaching.As the carrier of chemistry curriculum,the presentation of safety education materials in textbooks has an important impact on chemical safety education.Summarize the knowledge of chemical safety education in domestic and foreign literature and documents,and construct the textbook analysis framework.In this paper,the compulsory high school chemistry textbooks are selected as the research object,and the safety education materials are sorted out.Thirdly,the paper carries out quantitative analysis and comparison from two aspects of knowledge coverage and material characteristics,and takes "acid rain and its control" as an example for qualitative analysis and comparison.Based on the research results,the following conclusions are drawn:(1)High school chemistry courses mainly involve six fields of national security education and three fields of life safety and health education,and are mainly distributed in science and technology,nuclear,ecology and resource security in the field of national security,among which science and technology security and nuclear security are the most widely involved,36.19% and27.62%,respectively.(2)The third edition of the textbook does not fully cover the key points of safety education knowledge,and the material types are concentrated in the two major fields of ecology and resource security,science and technology security is involved,and other fields are missing to varying degrees.(3)The characteristics of the materials reflect the consistency: they all reflect the teaching function of developing the quality of "scientific attitude and social responsibility",and the dimension of "scientific attitude" is more prominent;Columns and text of the material distribution is more obvious;The material content is mainly presented in the form of plain text and graphic combination.Focus on integrating interdisciplinary knowledge into safety education materials,focusing on the integration of natural science and engineering technology knowledge;The proportion of practical activities and context Settings is low,but context Settings pay attention to authenticity.
