This article adds to the existing literature on nonformal learning in education in general and the role played by written feedback in providing the space for such learning in particular. The study was conducted in an English as a Foreign Language context in which the participating students received written feedback on their English writings. Employing qualitative interviews and stimulated recall methodology, we explored interstudent interactions, cross-cultural understanding, and initiation into communities of practice, and categorized these as reactive and deliberative types of nonformal learning. Drawing upon Eraut's typology of nonformal learning, we would argue that formative written feedback provided on students' writings could lead to nonformal learning because it encourages them to act upon it.
