This research was conducted by applying experimental method with 24 students as the sample and they were taken by using total sample technique. Test and observation were used in collecting the data. Based on descriptive analysis, it was found (a) the average of students’ mathematical problem solving ability before using AIR learning model was 44.39 (fair category) and after using AIR learning model was 82.95 (very good category) and (b) 29.2% students got effective category, 62.5% students got effective category, and 8.3% students got enough effective category.
