The examination of teacher educators' own practices through self-study research has been well established and self-study aligns with the growing interest in open educational resources (OER) and open pedagogy. This research used a self-study method of a Science, Technology, Engineering, Art, and Mathematics (STEAM) OER project, Form and Function(s): Sustainable Design meets Computational Thinking. Two research questions were pursued: How do open pedagogy attributes contribute to a transdisciplinary STEAM OER pedagogical stance? And how can one apply visual artifact self-study as intentional critical friends to examine professional value and to enhance pedagogical self-understanding? The researcher analyzed visual artifacts of created and documented images that supported the process of her interrogations of transdisciplinary curriculum development and open pedagogy. The sites and modalities of the artifacts were questioned and answers recorded using a critical visual methodology. Klein's (2008, 2018) transdisciplinary thinking and the eight attributes of Hegarty's (2015) open pedagogy frame the interrogation of the images and the connections made to curriculum theorizing. The self-study provides conclusions to the role of visual artifacts when conceptualizing the gestalt of complex ideas and relations. The self-study provides warranted assertions for open educators and researchers interested in the practices of transdisciplinary, open curricular and pedagogical processes alongside the eight attributes of open pedagogy, and the role of critical self-reflection.
