A Comparative Study Of The Old And New Textbooks Of High School Geography "Planet Earth"

In 2017,the Ministry of Education promulgated the "General High School Geography Curriculum Standards(2017 Edition)",and under the guidance of this standard,new versions of textbooks have been published one after another.In order to understand the characteristics of the new textbook,the corresponding teaching suggestions are put forward,and the text system,image system and activity system of the new textbook are analyzed under the guidance of the course standard,and the following conclusions are drawn.Compared with the "General High School Geography Curriculum Standards(Experimental Edition)",the 2017 version of the course standard has changed greatly in the curriculum concept,which is mainly reflected in the fact that the 2017 version of the course standard focuses on geographical core literacy.In the content standards,action verbs are mainly associated with the above evaluations,and the 2017 version of the course standard has relatively single requirements for students,but the overall difficulty requirements have not been reduced.Behavioral conditions are mainly related to teaching methods,and the 2017 version of the course standard focuses on the constraints of behavioral conditions,and each content standard has corresponding behavioral conditions.The cognitive content is mainly related to the course content,and the cognitive content of the 2017 version of the course standard is reduced compared with the2003 version of the course standard.After comparing the text system,it is found that the biggest feature in the teaching guidance part is the increase of teaching guidance,in addition,the expression of teaching guidance is more discipline-integrated,and teaching guidance is closely related to difficult knowledge.The titles of the new textbooks are more detail-oriented and graded more granularly;The geographical concept in the main text part is more precise,and the basic knowledge of geography is reasonably divided from the basic principles of geography;The selection of teaching auxiliary materials in the new teaching materials has the characteristics of the times and the combination with China’s excellent traditional culture,and the setting of corner markers in teaching auxiliary materials is more reasonable.On the image system,the new textbook has a greater number of image types and more types,but the image density of the compulsory one is higher,while the image system density of the optional compulsory one is slightly lower.Among the changed images,most of the new images in the new textbook appear in the teaching guide and are closely related to difficult knowledge,the changed images pay more attention to their wholeness,and pay more attention to the communication of regional cognition,and most of the deleted images are landscape maps.In the activity system,the number and type of activity system of the new textbook change less,but there is a large change in the design of the activity.The activity system design of the new textbook has the characteristics of focusing on the cultivation of students’ core literacy,the scenario design is more detailed,the problem design is gradual and more life-oriented,and the activity investigation method is mainly short answers,supplemented by drawing,filling in the blank(filling in the form)and carrying out communication.Combined with the characteristics of the above systems,it can be concluded that the compulsory one of the new textbook is more biased towards the basic knowledge of geography,while the optional compulsory one pays more attention to geographical principles.In addition,teaching suggestions are put forward for the two new textbooks,and in the teaching of compulsory one,we should pay attention to the cultivation of students’ "geographical practical ability",pay attention to the selection of teaching materials,reasonably determine the key and difficult points of teaching,appropriately reduce the difficulty of teaching,and attach importance to creating situations in teaching;Optional compulsory high school should focus on cultivating students’ "regional cognition" literacy in teaching,rationally handling teaching material activities,paying attention to teaching in combination with China’s excellent traditional culture,and linking the design of problems with students’ lives.
