Comparative Study On The Extension Of The Mathematics Exercises In Junior High School

Exercise is an important part of the textbook, the pros and cons of the quality of exercises will directly affect the teachers to teach students the level of quality. Therefore, the research on textbooks is an exercise of great significance and value of the work. The research is exploratory exercises from a type of junior high school exercises comparative study In addition to the quantitative comparisons of the number of exercises, type the text level, from the perspective of the development of students, teachers agree on exercises and use made a number of suggestions and comments, in order to achieve a better comparison study effect.In this research,"Beijing Normal University Edition" contact extension exercises and "PEP" extension to explore exercises seventh textbooks, comparative analysis of four aspects of the number, type, the use of the exercises and the cause of the error from exercises, obtained the following conclusions:(1) the number of exercises, the new "PEP" large number of exercises (58), Beijing Normal University exercises the small number (19). Extension class for each chapter exercises, Beijing Normal University, the number of exercises are less than the corresponding content in the new "PEP".(2) In the exercises type, select, judge exercises in two different versions of the new "PEP" and "Beijing Normal University" textbooks Extension class exercises does not appear; more concerned about is the short answer and calculation problems; pay more attention to design questionnaires, exercises and hands-on exercises; but the new "PEP" containing proofs listed questions and interpret blueprints application questions, Beijing Normal University,"but these four types exercises; fill in the blank, Beijing Normal University, the amount of questions far greater than the new "PEP" Overall, the divergence of the two different versions of textbooks open questions In comparison, the new teach version of richer, the surface of the problem is also relatively high, wider, but reflect on the concept of the new mathematics curriculum standards" have their own characteristics, and attach great importance to improve students’abilities and interest in learning mathematics, but relatively the focus is different.(4) Analysis Extension exercises wrong, from the knowledge level, the logic level and ability level error exercises divided.Finally, to provide some reference to the number of junior high school mathematics textbooks Extension class exercises, type, selection of design, divergent class exercises teaching junior high school mathematics teachers and students how to use the exercises to provide some constructive suggestions to improve learning, reference and help.
