Replication research in L2 collaborative writing: Replications of Fernández Dobao (2012) and Bikowski and Vithanage (2016)

Over the past two decades in the applied linguistics subfield of second language (L2) writing, there has been considerable interest in the topic of collaborative writing (CW). Studies in this domain have investigated different phenomena such as the nature of learner-to-learner interactions, the learning outcomes of CW, and students' perceptions of these activities when implemented in the classroom. Despite the large number of studies that have been published to date, replication research has been scarce. As such, the current article opens by making a case for replication work in the area of L2 CW, arguing why such research is both important and necessary. Following this, the article turns to a discussion of two key CW studies that have been highly influential in the L2 writing sphere. These studies are described in detail, and suggestions are provided as to how and why these studies might be replicated in the future.
