Abstract
The reasoning abilities of Vocational students are still low. This qualitative study describes student’s mathematical reasoning in solving problems based on Polya's steps. The subjects were three students, high (ST), medium (SS), and low (SR). Research was conducted by analyzing the work results subjects and interviews. Research shows that Understanding problems, subjects analysed problem:ST, SS, SR revealed problem information; ST was relevant in representing triangles, SS, SR; ST identified tangen, SS, SR sine rule. Planning, subjects connected the trigonometric comparison. Implementing plans, subjects applied strategies:ST used procedure by setting the solution step and the correct calculation, SS, SR incorrect; ST, SS reviewed strategies by checking the calculation/formulas, SR not. Looking back, subjects reflected the solution:ST, SS did not write the conclusion and considered the fairness of the solution, SR not.
