The purpose of this design case was to document rigorously the process and decisions made during the development of a five-day, pre-semester virtual orientation for International Graduation Teaching Assistants (IGTAs) and their domestic counterparts, teaching in an English as a Second Language Composition (ESLC) Program of a large land-grant university. The design was grounded in a front-end analysis as well as a theoretical framework comprising Crenshaw's (1989) Intersectionality and Wenger's (1998) Virtual Community of Practice (VCoP) theory. These theories were leveraged to focus the design on IGTAs' educator identity development and their linguistic and cultural marginalization. VCoP theory provided a practical architecture for the virtual learning environment with its three modes of belonging (i.e., "engagement," "imagination," and "alignment") as well as several enabling structures (i.e., "support," "sponsorship," and "recognition"). The design intended to purposefully engage IGTAs in social practices and dialogue that would support their sense of belonging and educator identity. While significance can be extracted from the pre-planned, explicit alignment of certain design elements with the modes of belonging, precedent can also be derived from elements that emerged during the design process.
