其他摘要:In April 2020, when the COVID-19 infection spread, 283 people made 500 cloth masks in a home economics class at a junior high school. In order to develop the ability to take a countermeasure to the crisis, the educational effect of the mask-making class by taking advantage of already learned knowledge was examined. Many students realized that they had achieved their goals in a short period of time by making use of the skills had already learned and the assembly line production. Using knowledge and skills to allocate roles in order to sew in a short period of time and cooperating with each other was effective in responding to unexpected situations such as COVID-19. In addition, collaboration with teachers of other subjects with specialized knowledge beyond the framework of the subject was very effective in this practice. The practice also revealed the necessity of maintaining sewing machines that failed due to metal fatigue, and deploying computerized sewing machines to repair fabrics at schools.
