Abstract
The aim of this paper is to investigate the effectiveness of teachers' instructional prompts when students are doing yukata sewing. This was done by analyzing 28 students' descriptions of their interpretations of prompts and what they learned in each of 12 lessons. A lot of students understood the teacher's intention and interpreted the prompt individually, and in detail. They acquired not only practical sewing skills and knowledge of the materials used, but also abilities which are necessary for daily life, for instance, the procedure for sewing and how to avoid dangerous situations. In repeating dull work as well as in doing difficult independent work, a lot of students reported awareness of their internal transformation and showed insights into the relationship between what they learnt about sewing, and themselves.
