A Quantitative Comparative Study On The Difficulty Of Geography Teaching Materials In Senior High School

Along with reforming of the basic education curriculum, textbook compilation system transition from "one" to "more than a standard", For how to select the appropriate throughout the actual local materials there is disagreement. In the au-thor’s opinion, To make the right choice, one of the key problem is to grasp the characteristics of each version of high school geography teaching material, which is an important aspect of teaching difficulty must be considered. The purpose of this study is to take the "earth in the universe" as an example, through the analysis and comparison of four versions of the difficulty of high school geography textbooks in order to provide a reference for the preparation of high school geography textbooks and designers to select suitable and to provide help for the related departments and teachers to choose suitable for students in the area of geography textbook.So far, Chinese scholars Fuquan Huang, Jiansheng Bao, Ningzhong Shi, Boqin Liao and other scholars established curriculum difficulty quantify the corresponding evaluation model,which provides a solid theoretical foundation for the quantitative analysis of curriculum difficulty. In this paper, course difficulty model Professor Ningzhong Shi established is N=aS/T+(1-a)G/T, Under the new curriculum, The difficulty of knowledge is analysised for the "earth in the universe" of curriculum standardsand and four versions of high school geography textbooks,and Compared the goodness of fit of each edition of the textbooks and curriculum standard,Calculated the actual difficulty levels that four versions textbook. I reference the model that the difficulty of inquiry and the difficulty of expand maked by Boqin Liao, and construct the final model combined with the characteristics of geography itself, The model is:difficulty=depth/breadth, The contents of the"earth in the universe" to the difficulty of inquiry and expand is analyzed for static quantitative evaluation,and draw the corresponding conclusion.The main research work is as follows:1. Through access to a large number of the domestic and foreign research literature related with the teaching difficulty, this paper has summarized the researchresults of various disciplines Curriculum difficulty, and focus on the geography teaching difficulty literature collected and analyzed in detail.Compared with the structure of the PEP, Hunan Education Publishing, Sinomap Press and Shandong Education Press, the structure, and the structure of "earth in the universe"is horizontal Compared, quantitative research on the follow-up materials difficult to do a good bedding.2. Influence factors of three dimensions on difficult of knowledge content,inquiry and expand is analysised of high school geography teaching, and drewedup of the the evaluation standard in various dimensions, Initially formulated the knowledge difficulty evaluation, inquiry difficulty evaluation model and the expanded difficulty evaluation model of high school geography teaching, every dimension of depth of curriculum standard and four editions of geography textbooks for senior high school is assigned firstly by experts and teachers, According to the quantitative evaluation model of the preliminary formulation and evaluation standard, Combining the opinions of experts to modify the evaluation standard to get the final relative perfect assignment criteria and models.3. According to the final static evaluation data about the knowledge difficulty, inquiry difficulty and the expanded difficulty, analyze and compare the difficulty of the various versions of the differences in geography textbooks for each dimension, combing with quantitative evaluation model.Conclusions of this study are as follows:1. The results of knowledge difficulty about "earth in the universe" in edition of geography textbooks for senior high school and curriculum standard:In breadth, the PEP and Sinomap Press are equal and the maximum breadth,Secondly, respectively is Hunan Education Publishing and Shandong Education Press, the breadth of curriculum standard is the smallest; In depth,The depth of curriculum standard is the largest,followed by that of Sinomap Press, Hunan Education Publishing, Shandong Education Press and PEP; In the course time,The largest class is Shandong Education Press, followed by curriculum standards and Sinomap Press in the same class plates, then PEP, Hunan Education Edition least;In the difficult, The most difficult is Hunan Education Publishing,Then, PEP, Sinomap Press, curriculum standard and Shandong Education Press.2. The goodness of fit of each edition of the textbooks in"earth in the universe" and curriculum standard:The goodness of fit of comparable depth, Shandong Education Press is the largest maximum, and the maximum deviation with curriculum standard, Then, Hunan Education Publishing, Sinomap Press and the PEP, Comparable depth of PEP is the most consistentand with curriculum standards;The goodness of fit of comparable breadth, The goodness of fit of comparable breadth sort are:Hunan Education Publishin, the PEP, Sinomap Pressand Shandong Education Press, So, Comparable breadth of Shandong Education Press is the most consistentand with curriculum standards; The goodness of fit of difficulty, Hunan education press fit value of the largest, followed by the PEP, Sinomap Press and Shandong Education Press, Shandong Education Press is closest to the curriculum standards, and the degree of deviation from the minimum.3. The results of inquiry difficulty about "earth in the universe" in editions of geography textbooks for senior high school and curriculum standard: In breadth,Hunan Education Publishing is largest, Then, the PEP, Shandong Education Pressand Sinomap Press; In depth, the order is Hunan Education Publishing, ShandongEducation Press, the PEP and Sinomap Press, Hunan Education Publishing is largest, Sinomap Press is lowest. In the difficult, Shandong Education Pressis the largest, followed by, the PEP and Sinomap Press are the same, Hunan Education Publishing is the smallest.4. The results of expanded difficulty about "earth in the universe" in editions of geography textbooks for senior high school and curriculum standard: In breadth,Hunan Education Publishing is largest, followed by the same version of the PEPand Shandong Education Press, Sinomap Press is lowest. In depth, Shandong Education Press is largest, then, The PEP and Sinomap Press, the last is Hunan Education Publishing, In the difficult, the most difficult is Sinomap Press, then, Shandong Education Press, the PEP and Hunan Education Publishing, Hunan Education Publishing is lowest.
