Reporting on the relationship between homework, foreign language learning and self-regulated learning, this paper examines how a teacher used homework to promote Japanese language learning in a Year 4 class at an Australian primary school. The study drew on naturally occurring data including classroom observations and student-produced video of themselves completing homework as well as interviews and a collection of documents and artefacts. Using a sociocultural analytical lens, the study found that homework can be a vehicle for the development and practice of self-regulation strategies as enablers of successful language learning, but only within certain conditions established by teachers, parents and the students themselves. The study found that in some instances teachers may not recognise or adopt opportunities for student self-regulated learning. The paper concludes with a pedagogical homework cycle to assist teachers to mobilise the potential of homework as a means of scaffolding foreign language learning beyond the classroom.
