Promoting the education of quality engineering at the university, the teaching method for the S/N ratio using a familiar material easy to understand for students has been proposed. The material is a card made of several sheets of paper with different surface condition and appearance, and is scoring depending on the smoothness of the surface with the fingertips. A lecture of quality engineering using the proposed material for the students of the faculty of engineering was conducted, and its effect was examined qualitatively. In order to give the students to understand how to express the S/N ratio by measuring the variation,we made the students to be compared with the S/N ratio of other students. As the results of the experiments using the materials proposed, it was cleared that S/N ratio calculated in these experiments was included not only the variation of the senses but also variations of the method for quantifying the sense. Increasing the level of work proficiency by repeating the scoring tasks, the variation of the S/N ratio was reduced. In addition, the effect of education using this materials was examined qualitatively from the results of the questionnaire conducted after the lecture. As a result, many students made remarks that they were able to understand the importance of quality engineering. Experiments by scoring the smoothness of the paper led to the improvement of the motivation for the study of quality engineering.
