Telecollaboration is a type of online learning arrangement between geographically distant participants for the development of language and intercultural competence. After two decades of research, it is an apt time to engage in a systematic review of previous studies in the form of a scoping review in order to illuminate the pedagogical practices commonly used in telecollaboration. The study synthesized 55 distinct telecollaboration projects that took place in university foreign-language classes and utilized synchronous computer-mediated communication (SCMC) tools to answer (1) What are the typical arrangements of SCMC-based telecollaboration (e.g., participants, project set-ups, and interaction set-ups)? and (2) How have SCMC-based telecollaboration projects changed over the last two decades? We identified six commonly adopted arrangements of SCMC-based telecollaboration. We also found that, while certain pedagogical practices in telecollaboration have matured, the field is undergoing reconceptualization and expansion with the advancement of technology and diversification of participants. We conclude the article with suggestions regarding reporting practices in telecollaboration research, thereby enabling more rigorous synthesis in the future.
