From the concept of “mode of information”, It was Mark Poster, an American historian and media researcher, who considered communication in the electronic media environment. Through the concept of “mode of information”, when considering the changes in physical education brought about by “Covid-19”, it is necessary to consider it not only as an object requiring solutions to clinically unprecedented social issues, but also from the perspective of historical and social transformation as a change in the media environment. In this paper, I considered the process by which the learner himself or herself informatizes the performance recorded on a tablet PC using keywords such as self-instruction, “body as an image”, database, and subjectivity. As a result, I explain how Covid-19 pandemic brought about a transformation in the learning space and the way physical education is taught as it helped disseminate and normalize the use of tablet PCs in schools. Specifically, I conclude how this radically transformed the politics of the boby that was previously hidden from view.
