A Comparative Study On The Difficulty Of Junior High School Physical Textbooks In China And South Korea

Science education as an important part of education,plays a vital role in improving the scientific literacy of all citizens. Therefore science curriculum reform has been widespread concern around the world, China also places an emphasis on basic science education reform, important part of the curriculum reform is the reform of teaching materials. Preparation of materials of concern at the same time, China’s "Education Plan" put forward to "rebalance teaching materials, scientific design course difficulty. Textbook as teaching the most basic information, front-line teachers to understand the textbook difficulty in order to based on textbooks adjust to teaching content, so that a more reasonable and effective teaching. Therefore, the analysis of the degree of difficulty of the textbooks can further improve the theory of textbook writing, rich physics curriculum and teaching theory; provide the impetus for our textbook reform, improve teachers’curriculum secondary development, optimize the physical classroom teaching.This article as a starting point in the textbook literature on the basis of reading and combing, selecting the junior middle school physics textbooks and Korean version of Venus science textbooks (the part of physical) as the research object, constructed by the Task Force textbooks comparison of ease of index system, knowledge points in the two sets of textbooks, experiments, examples, exercises, expanding the material of the depth distribution of the breadth of the distribution and knowledge, experiments, examples, exercises a comparative study of quantitative draw two the sets of textbooks difficulty, as well as the three cognitive levels breadth and depth of the distribution. In the same time, in order to have a better understand of the textbook set, I also compared the knowledge of a topic distribution. I combine the characteristics of the relevant literature and two sets of textbooks in the preparation of, the difference between the two sets of textbooks on the difficulty and difficulty gradient, and analysis behind the design intent and teaching philosophy.Through research, the author draws, PEP textbooks difficulty, the difficulty of experimental examples difficult, and exercises difficulty than the Korean version of Venus is high, and PEP textbooks breadth of experimental breadth, breadth and examples and exercises breadth. PEP textbooks knowledge, experimental average depth is small, that the PEP pay more attention to the wide and shallow learning. The average depth of the people of the examples and exercises, and the subject of the calculation of class compared to the Korean version of Venus to prove that the PEP textbooks pay more attention to the student computing power and the use of formula ability. In addition, the creation mode Korea Venus textbooks, Exploring expangding experimental exercises set, expand the material has obvious characteristics, is also an important reason of the to affect Korea Venus textbooks difficulty.Propose the following:the knowledge teaching the basics, appropriate enrich and expand; according to the author draws the relevant conclusions of the difficulty of textbooks based textbook improve investigations to form appropriate to reduce the difficulty of the inquiry experiment, to increase the enthusiasm of students to participate in; presents a more interesting and situational exercises.
