Russian scientific writers understand this necessity too; however, evidence suggests that these particular researchers are under-performing relative to similar non-native English speakers. The considerable challenge Russians…

Despite previous research suggesting that first language (L1) use fulfills important functions in collaborative writing (CW) tasks, research has yet to examine whether L1 or second language (L2) use may lead to variation in the lexico-grammatical aspects of learners' collaborative texts and the pair talk. Using a corpus-based approach, this study…
