This article discussed the development of hypothetical learning trajectory for integral topic which based on realistic mathematics education for class XI Senior High School (SMA). The study focused on the phase of one to one evaluation by using observation. In this phase, we try it out to three students which divided into low, medium and high mathematics ability. Based on the observation, it can be concluded that the designed Hypothetical Learning Trajectory (HLT) can guide the students to achieve the expected purpose, that is the students can construct and discover the concept of integral by themselves based on their experience. Students use their reasoning ability to solve the given real problem so that their mathematical reasoning ability is improved. © 2020 Published under licence by IOP Publishing Ltd.
