Difficulty Ordinary High School Physics Textbook

Along with the further development of curriculum reform of basic education," one stand several textbooks" has realized in China.However, how to choose the suitable textbook for the realities of this region? when the local education administrative departments, schools and teachers face multiple versions of textbooks, they must solve this problem.I think:if we want to make the right choice,we must know the similarities and differences and characteristics of the various versions of senior school physics textbook. To grasp the similarities and differences and characteristics, it is compulsory to make an objective and realistic evaluation. The difficulty of textbook is an important aspect to reflect the materials characteristics. At present, under the background of diverse physics textbook, we must consider the difficulty of teaching materials to select textbook suitable for a group of students. The main purpose of this reasearch is to analyse and study the present situation of the difficulty of textbook, and then, design scientific evaluation model.last,I study the difficulty of physics textbook.Therefore, this evaluation of the senior school physics textbooks, which is based on the difficulty, not only can provide the advices and help for the writers and designers of the high school physics textbooks, but also can make up the blank of the textbooks evaluation research. At the same time, this study can also help the schools, teachers and related departments to identify and choose high school physics textbooks.This paper is about the evaluation of the difficulty of senior school physics textbooks, the main work about this paper includes the following aspects:1.1analyzed and summarized the research theory and the results at home and abroad by studying the literature, which are about the difficulty of textbook and textbook evaluation.2.According to the existing research at home and abroad and the new physics curriculum standard, I established the evaluation model of the difficulty of textbook combining the characteristics of senior school physics textbooks; Evaluation model is divided into the evaluation model of the difficulty of knowledge and the evaluation model of the difficulty of scientific inquiry and the evaluation model of the difficulty of exercises and the evaluation model of the difficulty of extra-curricular content.3.According to the evaluation model of the difficulty of textbook,I assign numerical value for textbook content from various dimensions in physics textbook1&2published by PEP and shanghai science and technology press.4.According to the assignment results,I evaluate and compare the difficulty of knowledge and the difficulty of scientific inquiry and the difficulty of exercises and the difficulty of extra-curricular content in physics textbook1&2published by PEP and shanghai science and technology Press.Based on the above research, I mainly get the following some aspects of conclusion:l.In the width of knowledge,concerning the subject of the interaction and the law of motion,it is the largest in two editions of textbooks. On the whole, the edition of shanghai scientific and technological education press ranks first, the edition of PEP is in the second.2.1n the depth of knowledge, the demand of knowledge is focused on the level of acquaintance and understanding. In general,the depth of the knowledge ranks first in physics book1published by PEP,the edition of shanghai scientific and technological education press is in the second.for physics book2,the edition of shanghai scientific and technological education press ranks first, the edition of PEP is in the second.3.In the area of the difficulty of knowledge, concerning the subject of the interaction and the law of motion,the average degree of difficulty of knowledge is the largest in the editions of PEP,but the difficulty of knowledge is the largest in the subject of mechanical energy and energy resources. In general, the difficulty of the knowledge ranks first in physics book1published by PEP.the edition of shanghai scientific and technological education press is in the second.for physics book2,the edition of shanghai scientific and technological education press ranks first, the edition of PEP is in the second.4.In the width of scientific inquiry, for the physics book l,the edition of shanghai scientific and technological education press ranks first, the edition of PEP is in the second, for the physics book2,the edition of PEP ranks first, the edition of shanghai scientific and technological education press is in the second.5.In the depth of scientific inquiry,the demand of scientific inquiry is focused on the level one. for the physics textbook1,the edition of shanghai scientific and technological education press ranks first,the edition of PEP is in the second. for the physics book2,the edition of PEP ranks first, the edition of shanghai scientific and technological education press is in the second. In the difficulty of scientific inquiry,for compulsory textbook, the edition of shanghai scientific and technological education press ranks first, the edition of PEP is in the second.6.1n the difficulty of exercises, for the level of scientific inquiry and the goal of exercises and calculated amount, the physics book1published by PEP ranks first, the edition of shanghai scientific and technological education press is in the second. For the level of scientific inquiry and the knowledge and calculated amount, the physics book2published by shanghai scientific and technological education press ranks first,the edition of PEP is in the second.7.In the width of extra-curricular content,first,the number of extra-curricular content is moderate in two editions of textbook.In general, for the physics textbook1&2,the edition of shanghai scientific and technological education press ranks first, the edition of PEP is in the second.8.In the depth of extra-curricular content,the demand of extra-curricular content is focused on the level one and two. In general,for the physics textbook1&2,the edition of shanghai scientific and technological education press ranks first, the edition of PEP is in the second.9.In the difficulty of extra-curricular content, for the physics textbook published by PEP, the extra-curricular content is presented by a way,which the width of extra-curricular content is small and the difficulty of extra-curricular content is large. For the physics textbook published by shanghai scientific and technological education press, the extra-curricular content is presented by a way,which the width of extra-curricular content is large and the difficulty of extra-curricular content is small. For the physics textbook1&2, the edition of PEP ranks first, the edition of shanghai scientific and technological education press is in the second.
