The present study compares two types of written corrective feedback (WCF), reformulations and models, and their effect on the output by thirty-nine English as a foreign language primary school children (age 11-12; A2 level) working individually and collaboratively. Additionally, the effect of collaborative writing (CW) on learners’ motivation was measured. Learners’ noticing of problematic features and their subsequent incorporation in their revised drafts after being provided with the two types of WCF were analysed, comparing the children’ production after being provided with the two types of WCF and comparing CW vs individual writing as to noticing and incorporation of features as well as motivation. Few statistically significant differences between the two WCF groups were found but, rather, tendencies in the following sense: the children using models noticed and incorporated more lexical items, whereas noticing and incorporation of learners in the reformulation group was generally related to grammatical and spelling features. As for the comparison between the pairs and the individuals, some statistical differences were found, pointing to an advantage of CW over individual. These findings are discussed in light of the potential benefits of CW for young learners, and pedagogical implications are considered.
