In this paper, error analysis in the paper-and-pencil Mental Rotations Test (MRT) was conducted. In the previous study, direct monitor of eye fixation and protocol analysis have shown the difference of problem solving process between experts and novices. The purpose of this study is to examine whether such differences of problem solving process are reflected in the statistic property of the errors made by a large number of subjects.
Following results were obtained: 1) Solving process by mental rotation was reflected in error made by both experts and novices. 2) Solving process by detecting structural features was reflected in error made by novices.
The error analysis also revealed the unequal difficulty of each two part in the MRT. From the viewpoint of item order, the reconstruction of the MRT will be an interesting topic in the future work.

Compute aided design (CAD) has been playing a growing role in design and drawing education. Today, CAD education is regularly conducted as a supplement to conventional education based on drafting by hand. The ultimate goal of design and drawing education is to cultivate both overall ability and problem-solving skills (to nurture creativity) in students. To achieve this goal, it is necessary to evaluate methods for integrating CAD and conventional hand-drawing educational systems.
In this paper we examined an educational method whereby students use CAD to consider the relationship between a drawing and an actual object. Students learn to transform a drawing into an actual object and vice versa (i. e., visualizing a final product) .
Group design was conducted using a product on the market as the subject matter. The lectures and exercises were given to a limited group of students. They learned to use CAD effectively, given the specific instruction that it was important to have a clear goal and a distinct idea of the design process.
