| The view of the nature of science is an important part of scientific literacy.The teaching of the nature of science is not only an important link to improve teenagers’scientific literacy,but also a relatively weak part in current science education.The research on the teaching of nature of science in high quality ministerial class can provide excellent reference for the teaching of nature of science in ordinary class.History of science is an important carrier of teaching.Textbooks are the basic basis and materials for teaching.Therefore,the author takes the "One Teacher,One Excellent Course"ministerial-level high quality course on the history of science on the National Education Resources Public Service Platform as the research object,and takes "how about the teaching of the nature of science based on the history of science in the high quality course at the ministerial level?what are the merits or demerits?" and "how to improve the teaching of the nature of science based on the history of science?" as the research questions,and carries out the following two basic research contents:(1)select or develop an appropriate analytical framework to conduct qualitative and quantitative analysis on the teaching content,teaching behavior and teaching methods of the nature of science of high-quality courses,and present the redeems and improvement suggestions of high-quality courses;(2)based on the analysis results of lesson examples,this paper puts forward effective suggestions on the selection of teaching content,application of teaching methods and development of teaching behavior of the nature of science,and makes instructive suggestions on the nature of science teaching based on textbooks.The conclusions of this study are as follows:1.The conclusion of the analysis of the teaching content of the nature of science:most of the high quality courses have explicit teaching contents of the nature of science,indicating that the high quality courses of the history of science pay attention to the teaching of the nature of science;the lack of comprehensiveness and balance in the teaching content of the nature of science,which is manifested as more emphasis on the nature of scientific inquiry,especially the observation and inference and the empirical dimension.2.The conclusion of the analysis of teachers’ scientific essence teaching behavior:most of the teachers can reach a medium level in terms of production,but they are mostly at a low level in terms of teaching objective construction,teaching theme design,distinguishing observation from inference,reflective activities and homework design.3.The analysis conclusion of teaching method of the nature of science:about half of the high quality courses can use the dominant teaching method,which is one of the effective teaching methods,but less of the courses can use the most effective"dominantreflection" teaching method.In general,the teaching of science essence in the high quality course of history of science is not ideal enough.Therefore,it is necessary to guide and help high school biology teachers in the teaching of science essence.In view of the common problems of quality courses in this study,suggestions for improving the teaching of nature of science based on the history of science are put forward as follows:1.Suggestions on the teaching content of nature of science:learn the teaching content of nature of science from high-quality courses,learn the teaching content of nature of scientific inquiry,and pay attention to the content of observation,inference and empirical aspects;According to the principle of "explicit utilization and recessive improvement",the teaching content of science essence in textbooks of history of science should be rationally adopted.2.Suggestions for the development of teachers’ teaching behavior of the nature of science are as follows:deepen the understanding of the teaching value of the nature of science,reasonably set the teaching objective of the nature of science,strengthen the application of WWHW thinking model and introduce the self-monitoring system of the nature of science teaching behavior.3.Suggestions on the use of teaching methods of the nature of science:comprehensive use of overt and reflective teaching methods of the nature of science and careful use of role-playing methods to present history.The innovation of this study lies in:Keep close to reality and highlight the usability of research results:This paper deeply analyzes how to teach the essence of science in high quality courses,and gives detailed teaching guidance for 8 subjects of the history of science.This paper deeply analyzes the teaching contents of the nature of science in the new textbooks of the history of science,and gives detailed guidance for the use of 16 topics in the history of science. |
