Abstract
This paper aims to outline the course design for Japanese as a Second Language (JSL) education as a designated subject in high schools in Japan. The revision of Curriculum Guideline requires high schools to clarify the relationship between each subject studies and schools’ goal and to renew the value of evaluation by introducing an evaluation system. The author provides practical examples and suggests two points, 1) it is important to ensure the role of JSL education in a high school to clearly integrate the school’s curriculum, 2) to evaluate Japanese ability, we should focus on not only language knowledge but also the general ability to solve problems in subject studies.
