عنوان مقاله [English]
3D Spatial ability is an important and vital ability for engineering disciplines in the fields such as designing, modeling, reverse engineering, production and manufacturing and etc. Furthermore, this ability plays an important role even for basic disciplines such as physics, mathematics, chemistry in the fields such as idea, perception of mathematics complex relations, structure of molecule and etc. There are several instances which can be presented that high spatial ability has a major impact on students’ scientific improvements. Recent research has demonstrated some strong links between spatial ability and educational success with different disciplines. Although the spatial ability of each person is unique, it can be improved by correct and classified education. In this paper, the effectiveness of Engineering Drawing course on improvement of students' 3D spatial abilities in Sharif University of Technology is evaluated by tests being taken and it is found good enough evidence that this course improves students' 3D spatial abilities remarkably.
