Teaching Research On Chemical Safety Education

Safety education is an important part of chemistry teaching.Combining safety education with chemistry teaching and carrying out chemical safety education in teaching is the requirement of "General High School Chemistry Curriculum Standard(2017 Edition)".On the basis of domestic and foreign research,according to the requirement of cultivating students' safety consciousness put forward in "General Senior High School Chemistry Curriculum Standards(2017 Edition)",this research aims at carrying out safety knowledge and safety consciousness education in Chemistry Teaching in combination with specific teaching contents,and exploring the teaching strategies of chemical safety education.In order to strengthen students' safety consciousness and improve their ability to deal with safety problems in chemical experiments and social life.In this study,before teaching practice,we interviewed chemistry teachers at different levels in X Middle School of Tianjin Binhai New Area,and found that there was less safety education in chemistry teaching.A safety knowledge test was conducted among the students in Class X of Senior One.It was found that the students in this class had insufficient safety knowledge reserves,low level of safety awareness,and their ability to deal with unexpected safety problems needed to be improved.Based on the current situation and the analysis of curriculum standards and textbooks,the instructional design of chemical safety education for "Elements Concentrated in Seawater-Chlorine" and,Sulfur Dioxide" has been formulated.In order to make the teaching of safety education interesting,the teaching design integrates the real situation and safety problems skillfully on the basis of the safety education materials provided by the teaching materials,and organizes students to conduct simulation experiments with VMC simulation software during the class,so that students can experience the standardization of experiment operation.After the teaching practice,the safety knowledge of the class was tested again,and the teaching strategies of chemical safety education were summarized according to the teaching design and teaching practice.The results show that the teaching of safety education strategically in chemistry teaching is helpful to enlarge students'safety knowledge reserves,and to strengthen students' safety awareness and improve their ability to deal with safety problems.
