Abstract
I conducted OPPA(One Page Portfolio Assessment)for consumer education in the first year of university. The first step of my research method was conducting a bibliographic survey on the theory of OPPA, after which OPP learning sheets were utilized in classes from April to July 2018. Class improvements were made based on the students’ answers on OPP learning sheets, and further analysis through text mining of the answers before and after learning was made. The number of consumer citizen society-related keywords increased after the class and their relevance also became higher. The OPPA enables us to grasp changes in students’ learning, so I consider it effective for class improvement.
