Aiming at the development of our math textbook, the present study compares the revised 2007 and 2009 national curricula and makes a comparative analysis into the middle school math textbooks under the revised 2007 and 2009 National Curricula. Moreover, the study verifies whether those two curricula with different objectives have the same content in the textbooks. The results of this study are as follows:
Unlike the revised 2007 national curriculum, the 2009 one has changed the basic direction to a 20% reduction in the content of the mathematics subject matters with the application of the non-graded system reflecting on the “grade cluster” system, which is in accordance with the content of the 2009 national curriculum: the medium unit of linear equation showed an integration of two small units, linear equations and the use of linear equations. In case of the revised 2009 textbooks, it is a new attempt to compose stories arousing students'' interests at the introduction part and also to contain stories, illustrations and mathematician sections to help students better understand mathematics from various perspectives.
And also, the revised 2007 textbooks deal with the problems concerning mathematical creativity considered a developmental type for thinking-ability problem. However, the 2009 textbooks, enforcing mathematical processes with an emphasis on mathematical creativity, more diversely treat the types of communications, inferences, and problem solving abilities than the 2007 ones.
Furthermore, it should be investigate whether or not the results of the study will contribute to the development of mathematical creativity in relation to competence improvement of mathematical processes and additionally whether or not three or four line additional explanations, in terms of story telling, about mathematical subject matters aid in students'' understanding of mathematical content. In conclusion, problems of mathematical processes and composition of storytelling should be dealt with consistently in a compilation of math textbooks.
