Abstract
This study is conducted to analyze in depth the reasoning of students' mathematics in solving story tasks. The approach is qualitative with case study-type. The subjects are 6 students of senior high school grade XI; 2 students of high classification, 2 students of medium classification and 2 students of low classification. Data collection methods are in the form of story and interview questions. The results show: 1) Students belonging to a high classification if they can meet the six reasoning indicators; present mathematical statements of both what was known and asked either in the first or second question; propose a guess by estimating the answers and the process of given solution; do mathematical manipulation; make a conclusion; provide a logical reason when not meeting several indicators; and always check every settlement step; 2) Students belonging to the middle classification also meet the six indicators, just do not meet some indicators such as incomplete writing down what is known and not writing down what is asked primarily in the first question, having error in solving the problem for lack of understanding of the problem and not making conclusions, but can provide a logical reason when interviewed; 3) Students belonging to the lower classification do not meet some indicators, which are incomplete presenting what is known and do not present what is asked either in the first and second questions; may propose by estimating the answers and the process of the given solution but the solution process and its completion step wrong; can perform mathematical manipulations but there are errors in the process of completion, can not provide logical reasons when interviewed.
