The Application Research Of Socioscientific Issues In High School Chemistry Teaching

The implementation of the socioscientific issues is a powerful way to carry out the fundamental tasks of "moral education and people cultivation" and cultivate the citizens' decision-making ability and awareness of social participation.Through applying socioscientific issues to chemistry teaching in senior high school and taking the socioscientific issues caused by chemical technology as the carrier,a real situation is set up to guide students to carry out scientific argumentation and rational decision-making.The above measures are of great significance to the implementation of the core literacy of chemistry and the cultivation of students' sense of social responsibility.Under the guidance of constructivism theory and theory of moral development,the concepts of socioscientific issues and informal reasoning are defined,and the teaching research on socioscientific issues at home and abroad is summarized.By using the method of questionnaire,the author conducted a questionnaire survey on chemistry candidates and chemistry teachers in the first year of senior high school,and made a statistical analysis of the survey results.It was found that students usually knew socioscientific issues through the Internet and were actively interested in issues learning,and liked open and autonomous learning methods.Due to the influence of academic pressure,limited access to materials,few examinations and other factors,the current socioscientific issues has not been paid enough attention by teachers and students.At the same time,due to the tight arrangement of class hours,the limited ability of teachers and other factors,some teachers said it is difficult to carry out the teaching of socioscientific issues,and they hope to obtain training and guidance on teaching activity design.The method of case analysis is introduced into this thesis,it analyzes the excellent examples of "element and compound review based on socioscientific issues" on both teachers and students.On the basis of the valuable teaching experience in the excellent lessons and the questionnaire survey results,the ideas and strategies of socioscientific issues are put forward to provide guidance and help for front-line chemistry teachers.The design and implementation of the "nitrogen element and its compounds" and "electroplating" are carried out on the idea of teaching design,and the application of teaching strategies is reflected through teaching reflection.Shown in the analysis of the implementation effect of teaching,it can be found that students have higher classroom participation in socioscientific issues.They can better complete analysis,demonstration and scientific decision-making,reflecting a higher sense of social responsibility.But still,the ability of knowledge application and rebuttal remains to be strengthened.Some teaching suggestions in view of some problems existing in the teaching process are put forward,which can be used as a reference for teachers in teaching and promote the better implementation of the core literacy of chemistry.
