This study is a qualitative study designed to investigate the artistic development processes of undergraduate art education students a/r/tographically and to determine the role of portfolio preparation in this process. The present research was conducted in the workshop course of the 4th-grade students of the Department of Art and Art Education of a medium-sized university in the academic year 2022-2023 with the participation of 10 volunteer workshop students. The study group of this research was selected through criterion (purposive) sampling. The collection of the data of the research consisted of student educational development files (portfolio) prepared during the inquiry process, the question pool created, a/r/tograph opinions collected through a semi-structured interview form prepared by taking the opinions of field experts, peer opinions, expert opinions and student artistic products that emerged at the end of the process. Qualitative data analysis was used to analyse the data related to the a/r/tographic process, which is an art-based research method. Accordingly, content analysis was used in student, peer and expert evaluations of educational development files (portfolio). Students' artistic processes and a/r/tographic questioning processes were analysed using descriptive analysis. It was seen that the students were satisfied with the educational development files (portfolio) that they examined by making self-evaluation. Peers and experts who examined the educational development files (portfolio) stated that the files could generally be improved. It was observed that the students were involved in the a/r/tographic process in a determined or accidental way and that they continued the process by making inquiries. It was observed that students developed different perspectives with their artist identities and expressed themselves with process-oriented products that they reflected themselves.
