| Teaching material as the important tool of teaching activities, its reform becomes a key link in the process of new curriculum reform. With the advancement of new cu-rriculum reform, for the analysis of the teaching material to cause the attention of many education workers, among them the analysis of the teaching material the difficulty is an important and farreaching significance. The analysis of the teaching material the difficulty generally refers to indepth analysis the essence of the teaching material from the microscopic view. At this stage Chinese scholars research of the teaching material the difficulty to stay on the analysis and evaluation the domestic some teaching materials, there are few researchers choose foreign textbooks which choose rate is high with major domestic teaching materials to analysis and research, there are some shortage by contrast with other subjects such as math, chemistry. So, considering the lack of this type of research, the author chooses physics textbook published by PEP and Physics:Principles and Problems, choice of textbook’s content with the mechanics and electromagnetism to comparison and research.There are two main innovations in:first, at present the analysis of the teaching material analysis of experiments to explore the difficulty, the author from the seven dimensions of the difficulty of the two sets of teaching experiments to explore the detailed analysis and comparison; Second, aiming at the present stage physics text-book exercises and experimental analysis to explore the difficulty of no specific ana-lysis model, draw lessons from professor Jiansheng Bao building math model in the form of a difficulty, to build a comprehensive physical exercises difficult model with physical experiment and explore the difficulty.Research the mechanical part is divided into "movement" and "curve, gravity" two themes, the electromagnetism parts are divided into "static" and "electromagnetic phenomenon" two themes, according to the difficulty of building the model of the four theme respectively by comparing the content difficulty and problem sets, in order to get the two sets of more comprehensive textbook exercises difficult differences, the author also added a part of the research level of the college entrance examination physics questions the two countries. Through research, get the following conclusion:(1) The teaching material content, in our country the difficulty of the teaching materials in four theme content are less than the principle and the problem, schools teaching materials in breadth has obvious advantages, pay attention to the compre-hensiveness of knowledge, the problem of principle, the depth of the content, is fewer but better.(2) Textbook exercises, the overall difficulty of schools teaching materials in our country is lower than the principle and the problems, the problem sets teaching mater-ial not only quantity, but overall, especially in the operational level, analysis level and the difficulty of knowledge levels were significantly difficult to compare.(3) By analyzing the test of the two countries, We found that the difficulty of the questions in our country is higher than the test questions in US, We need further anal-ysis about the writing of the test questions sets in our country is whether reasonable.(4) About experiment to explore aspects, the experiment of teaching material arr-angement in China to explore the overall than the principle and the problem is simple, especially in the experiment and the experimental steps of application of the principle and the problem of the difficulty is significantly larger, but in the preparation of expe-riment equipment, our country is slightly difficult to some materials. |
