Task repetition (TR) is a valuable tool to direct learners' attention from meaning to language form. The first time learners perform a task their focus is on conveying meaning, whereas during the second enactment they tend to focus on the form of their message. Collaborative writing also promotes learners' focus on form, allowing extra time to pay attention to language use, and providing multiple opportunities for learners to pool their linguistic resources and co-construct meaning. Despite the increasing body of research on young learners' (YLs) second language acquisition process, few studies have addressed the effect of the repetition of collaborative writing tasks on this population's output. The present study aims to fill this gap by analysing the impact of TR on YLs' (age 11-12) attention to form, operationalized as language-related episodes (LREs). Forty (n = 40) beginner learners of English as a foreign language (EFL) worked with two types of TR: exact TR (ETR), where the participants repeated exactly the same task, and procedural TR (PTR), where the participants repeated task type but with different content. Contrary to most previous research, most LREs were form-focused, and resolved target-like in both groups. The results also revealed a statistically significant decrease in the number of LREs at time 3 in the ETR group, whereas the LREs in the PTR group remained stable. Pedagogical implications of these findings will be discussed.
