In this study, we examined the relevant parts of technical instruments for all grades in middle school mathematics textbooks that based on 2011 revised curriculum. Then we analyzed them by grade level, content areas, technical instruments types, types of teaching and learning, degree reflects the content of the curriculum. As a result, the goal of this study is to suggest a direction for how to take advantage of the technical instruments in middle school mathematics textbooks. The results of this study are as follows. First, the relevant parts of technical instruments in middle school mathematics textbooks had been concentrated in certain area, this area is a geometric area and a function area. Second, the technical instruments that is used in most of textbook were equal in each content area. Third, the teaching and learning types for the use of technical instruments were concentrated in the "inductive intended to explore", and the technical instruments were only used to guide to follow the simple steps. Fourth, it was found that in the relevant parts of technical instruments which reflects the information presented in the 2011 revised curriculum. It had been concentrated in "Understanding the principles of mathematics" and "Understanding the concepts of mathematics", but "understanding the laws of mathematics" and "problem solving ability improvement" were rare.
