Abstract
Reflection is an effective learning activity in subjective learning. However, when a self-evaluation rubric is used as a means for reflection, learners are burdened with reading sentences. In this research, by developing a system for coloring descriptive rubric words, we aimed to improve the evaluation efficiency by making it easier to compare the phrases. As a result of the introduction into classes of basic information subjects, the response time was reduced by approximately 14.7% by using the self-evaluation rubric system using coloring, and the evaluation efficiency was improved.
