Abstract
This study aims to describe the mathematical spatial ability of students in solving mathematical problems. The research method used is the descriptive qualitative research method. Data collection techniques were carried out by tests, interviews, and documentation. The research instrument used was a spatial ability test and interview items. The data sources of this research consist of (1) The subjects in this study are students who take field and space geometry courses in the mathematics department, one of the universities in North Sumatra, and (2) this research activity is all activities during the execution of test instruments up to the results of the test and the interview took place. Data analysis techniques include data reduction, data presentation, and concluding. The results of this study indicate that (1) students with a high level of mathematical spatial ability category can meet all the indicators of spatial ability that researchers use in this study (2) students with a category of moderate level of mathematical spatial ability can meet two of the four spatial ability indicators that researchers use. in this study (3) students with the low level of mathematical spatial ability, the category had difficulty fulfilling several indicators of spatial ability that the researchers used in this study.
