Since the reform and opening up,the education cause of our country has been advancing by leaps and bounds.Besides enjoying the satisfaction brought by the national good education policy,the demand for education is also getting higher and higher.The teaching material is the knowledge source of the students' knowledge.It is the most effective tool for systematic knowledge in the past.Therefore,in the new round of curriculum reform,higher requirements have been put forward for the compilation and content selection of teaching materials.The teaching materials in the market are full of Lin Lang and have their own characteristics.Among them,there are four versions of geography textbooks for senior high schools.A reasonable comparison of the difficulty of teaching materials is helpful to the selection of suitable teaching materials in various regions.The arrangement of the textbook conforms to the principle of the unity of science and ideology.It includes not only the basic knowledge of the subject but also columns of different depth,which not only serves as a tool for knowledge imparting,but also pays more attention to the cultivation of students' ability.We must follow the rules of textbook arrangement,not only analyze the difficulty of text knowledge,but also pay attention to the research of the difficulty of the inquiry activity of teaching material column and the difficulty of developing reading material.This paper evaluates the difficulty of teaching material from these three dimensions: the difficulty of knowledge content,the difficulty of inquiry learning and the difficulty of case study.Using the difficulty evaluation model of different dimensions constructed,the following conclusions are drawn:1.The difficulty of knowledge content is higher than that of Lujiao version.In terms of knowledge breadth,there is little difference between human education edition and Lu education edition,and the difference of knowledge depth is very great.The combination of pictures and texts is often used to guide learning induction,and the Lu edition is more straightforward in this respect.From the comparable depth of both,it can be seen that the depth of knowledge that students can excavate in unit time is higher than that in human education edition.2.The difficulty of inquiry learning is higher than that of human education.However,the proportion of different levels of inquiry learning content between the two versions is far different.There are 6 inquiry learning contents in the "material conversion" level,and only one knowledge point is involved in the "classified information storage" level.The depth of knowledge points in the inquiry learning content of the education version is mostly at the first two lower levels.This is why the Lu education edition spends a lot of time setting up the activity columns.The overallpursuit of the difficulty of the textbook balance.3.The case study difficulty of PEP is higher than that of Shandong version.The PEP "reading" "case" column for the argument of this argument,expand student knowledge.Shandong version only "knowledge window" to enrich the students' horizons.The dimensions of the difficulty gap is in three dimensions is the most obvious.Renjiaoban expansion material relates to a hidden depth,reasoning,Shandong version of most of the direct narrative,reasoning the content of inquiry learning part of a larger proportion.
