In order to form a graph to probe into the structure of students’ conceptualization of fraction , a test was design, and to analyze the outcome through the item Relation Structure Analysis (IRS) , thus the formation of structure, to explore the sixth grade students’ fraction concept structure. 　In this study , Feng Yuan Taichung Area with sixth grade students in three classes for the study, sampling after the IRSP questions related computer programs and structure analysis (IRS) to analyze and discuss the measurement data, from access to this group fraction concept showed students in the conceptual structure information, and the results are as follows: 1. the concept of fractional size of the comparison: subjects students "than a large one unit fractions" concept than "than a small fraction of 1 unit"concept clearly. 2. the concept of fractional multiplication of the size of the comparison: the multiplicand multiplied by the proper fractions, improper fractions, mixed fractions of their value after the larger or smaller need to strengthen the ability to think. 3. the concept of fractional division of the size of the comparison: the dividend multiplied by the proper fractions, improper fractions, mixed fractions of their value after the larger or smaller need to strengthen the ability to think. 　Finally, the result of this this study offered some suggestions and reference for teachers, teaching materials and future.
