| Social scientific issue is SSI,that is to say,in the process of its development,science and technology bring us some controversial social reality problems.The purpose of this paper is to explore the attitude of high school students towards the safety of genetically modified food,and introduce SSI education model in high school biology classroom teaching,so as to improve high school students' critical thinking ability,and lay a good foundation for their long-term learning and development of biology knowledge.Therefore,I choose two parallel classes of physical students,class 4 and class 5 of senior two,which I teach,as the research object,class 5as the control class,teaching according to the traditional mode,class 4 introduces SSI teaching mode,and successively carries out the same questionnaire survey of A and B,and explores the influence of SSI teaching on senior high school students' critical thinking ability through the comparison of pre-test data and post test data.In this paper,literature research,experiment and questionnaire are used to carry out the following work:Firstly,The research on the definition of SSI teaching is based on the mature and authoritative research conclusions on SSI teaching at home and abroad,integrated the way of combining SSI with biology teaching in senior high school,and obtained the significance of SSI teaching mode in senior high school biology teaching system,so as to make the teaching of curriculum structure better.The content of the course has been optimized to enhance the senior high school students' specific understanding and development of the application of biological knowledge in sociology.Secondly,starting from the existing teaching mode of high school biology,this paper analyses how to introduce SSI teaching content into the classroom,break the traditional classroom teaching form,trigger students' thinking contradictions,stimulate students' critical thinking ability,and update the teaching stage of high school biology classroom from the perspective of thinking solidification and breaking.Finally,starting from the status quo of senior high school students' understanding of genetically modified food,this paper explores how to stimulate students' interest in learning genetically modified knowledge,and puts forward corresponding measures for classroom construction and improvement,so that senior high school students can better adapt to SSI teaching mode,link classroom knowledge learning with the status quo of life,and improve the cultivation of students.Nurture and promote.Adopted the above analysis,the paper comes to the following conclusions: First,throughthe questionnaire survey data in volume A,it shows that most students have not formed their own cognitive system for genetically modified food,and they have not paid enough attention to this content in the high school teaching system;Second,through the research on different teaching strategies of two parallel classes,according to the questionnaire survey data,statistical analysis shows that the introduction of SSI teaching mode can improve the critical thinking of high school students to a certain extent Dimension ability.Based on the current situation,the following suggestions are put forward: 1.Under the impetus of the new curriculum reform,we should further improve the teaching mode,integrate knowledge imparting more with life reality,encourage students to actively understand the latest biotechnology trends after class,and strive for basic biological knowledge,social problems education and scientific side.The unification of law education and individual education needs.2.Under the guidance of the new curriculum standards,teachers introduce SSI education mode selectively from four dimensions: teaching objectives,teaching contents,teaching strategies and teaching evaluation standards,combining with the characteristics of the chapters,to help students further enhance their own criticism.Thinking ability,so that knowledge can be better internalized. |
