| With the deepening of educational reform,the core literacy of history has attracted widespread attention,and the unified edition of the high school history textbook has also emerged in time.The unit introduction is on the cover of each unit,which not only has the role of connecting the outline and leading,but also has a very important value for cultivating students’ core literacy in history disciplines such as materialist historical view and time and space concept,and the full and reasonable use of the unit introduction can also improve the quality of teaching and learning.The unit lead in the unified edition of high school history compulsory textbook has certain characteristics.The two-paragraph setting not only clearly summarizes the main content of the unit,but also clarifies the teaching guidelines.At the same time,on the basis of inheriting and innovating the previous textbooks,The compulsory textbook of high school history shows the characteristics of conciseness,science,guidance and illustration.The compulsory high school history textbook is based on teaching concepts such as cognitive discovery theory,recent development area and free learning concept,which not only shows its own guiding value,but also has great significance for cultivating the core literacy of history and different educators.By comparing the unit lead of senior high school history compulsory textbooks in the old People’s Edition,People’s Edition,Yuelu Edition and Beijing Normal University edition,the characteristics of the unit introductions in the unified edition of high school history compulsory textbooks are explored,such as delineating the overall appearance of the unit and closely linking it with the curriculum standards through concise expression.In order to better understand the teaching application of unit lead,the questionnaire and interview are used to carry out field research,and it is found that there are some problems in the application of unit lead in classroom teaching,such as the lack of understanding of the role of unit lead and the singleness of the way of unit lead teaching.Furthermore,it is analyzed that the value of the unit lead cannot be fully explored due to the teaching pressure brought by the traditional teaching method to solidify teaching thinking and the increase of teaching content.As for the application strategy of the unified edition of the compulsory high school history textbook,through the exploration and design of teaching cases,the unit lead is combined with the teaching of high school history,and it is concretely implemented in the teaching of the compulsory high school history course"Two Opium Wars".In teaching practice,teachers and students can control teaching and learning from the three perspectives of pre-class preparation,classroom utilization and after-class reflection.In addition,textbook writers can improve their writing from the aspects of content,structure and form,so as to give full play to the value of unit leads. |
