A Comparative Study Of Textbooks Based On The Nature Of Science

The essence of chemical science is one of the core concepts of chemistry in middle school.Chemistry,as one of the most important science courses in senior high school,plays an indispensable role in cultivating students' view of nature of science.As the direct carrier of teaching between teachers and students in school education,textbooks play a role as a bridge between educators and students,and need to be further revised with the emergence of problems in the process of use.As the support of the basic concepts and theories of chemistry,the knowledge of elemental compounds plays a transitional role in the teaching of chemistry in senior high school,and is a powerful carrier to cultivate students' view of the essence of science.It is the foundation of students' further study of chemistry and the common sense of life for each of us.In this study,the "elements in seawater" is selected in the teaching and learning methods,the idea is representative,always running through the study of high school chemistry,which plays a vital role in cultivating students' view of scientific essence.Based on the fact that the textbook should improve the students' scientific literacy and cultivate the concept of the essence of science,The main application of literature analysis,comparative research and practical research as a supplement to the text of the people's edition and Luke edition of the textbook "elements in the sea" theme of this part of the content from the content selection of the curriculum standard consistency,layout design,column setting,content,subject characteristics,STSE education perspective of in-depth comparative analysis.The study found that the two versions of the textbook "elements in the sea",in varying degrees,reflect the scientific nature.What's different is the typical representative element--chlorine,for example.focusing on the teaching of chemistry knowledge to construct the students' scientific essence concept,And LuKe version of this class content,multi-angle view about the textbook for chemical disciplines basic knowledge and ideas and social living environment is closely linked,from the perspective of the generation of knowledge and application to construct the scientific view of nature.In contrast to previous studies,this paper starts with the conclusion of the problems found in the research and the comparative analysis.On how to better optimize the textbooks reflects the nature of science content,by o 'clock chlorine chemistry teaching,after-school topic changes,chlorine bleaching condition inquiry experiment,LuKe version of the text word length,add chemistry history and fun is taken as an example to improve the implementation suggestion for your reference,Makes every effort to serve teaching between teachers and students,making the front-line teachers in again at the same time to improve the quality of teaching level and cultivating the students' concept of nature of science,hope in the new era textbooks compiled and revised with ordinary high school curriculum reform contribute little of their own power.
