Abstract
In previous research on subject area in mathematics, a model plan was created. Regarding linear algebra, the lecture content items listed are mandatory for all students who aspire to become mathematics teachers. In the Educational Personnel Licensing Act, the establishment of ``subject content composition subjects'' that would realize the fusion of ``subject area'' and ``subject teaching methods'' has been proposed and is being revised. Recently, our society has placed emphasis on inquiry activities in the curriculum content structure of mathematics. The purpose of the research is to deepen and expand the understanding of the content of subject-specific subjects through presentations by students, and to construct subject-specific subjects that foster skills and perspectives related to subject teaching methods. The research method is to practice and consider Linear Algebra II for first-year students. In the lectures, we try to represent matrices graphically, apply them to everyday phenomena, and cover topics related to high school mathematics to serve as seeds for the content of the presentations. As a result, students were able to present a wide variety of content.
