Abstract
At National Institute of Technology, Kisarazu College, the elective subject “Optional or Voluntary Activities” was introduced in academic year 2001, and has been practiced for 22 years. The subject covers three fields of students’ activities, including volunteer activities, and there are so many kinds of courses now. On the other hand, the legislation on education is sometimes amended, and it is necessary for us teachers to follow the revision. At the same time, we need to continue to check the situation of students. This paper discusses the effects of the field ‘credit approval based on the official certification examinations’ in English course.
