In this research, it is aimed to examine the schemes that emerged during the documentation formation process and the factors affecting the process in the context of a lecturer's "Documentational Approach to Didactics" theoretical framework. For this purpose, a case study, one of the qualitative research methods, was preferred in the study. Linear algebra courses teaching plan, course video recordings, clinical interviews and schematic representation of the resource system were used as data collection tools. The research participant is a lecturer who teaches linear algebra at the Faculty of Education of a state university in the Marmara Region. Content analysis was used to analyze the data. Elements related to the schemes that emerged in the process of creating documents as a result of the study have been determined as the fact that the achievements of the linear algebra curriculum are applied in a different order, the language of the selected resources is simple, the lessons are in the form of definition-theorem-example solution-quiz, the lecturer creates his/her own examples on the subject, the digital media resource is Google Meet, the resources and videos are shared in the classroom. In addition, it was concluded that the factors affecting the documentation creation process of the lecturer were grouped under four themes: student-based, faculty-based, mathematical concepts, and teaching environment.
