Abstract
At the College of Arts and Sciences of the University of Tokyo,students that had enrolled up until 2014 learned descriptive geometry based on hand drawings in the second semester and graphic presentation through the use of 3D-CAD/CG in the third semester. For students who had enrolled from 2015 onwards the contents in each semester was switched.To gain some insight into whether the modified curriculum influences the improvement of students' spatial ability,the Mental Cutting Tes （t MCT） was given prior to and after each of the two graphic science courses. The trend of significance on the difference between mean scores in the MCT prior to and after each course is inconsistent between fiscal years 2016 and 2017.Continuous investigation is required to examine the influences of the modified graphic science curriculum. The results of our investigation suggest that students who attend the class of descriptive geometry based on hand drawings have a higher spatial ability when evaluated by the MCT.
