This article provides an argument for the recognition of complementary alternative literacy learning spaces (CALLS) as a strategy for operationalising the notion of multi-literacies in classroom practice. The paper draws empirical evidence from a small-case project to support the claim that scratch, functioning as a CALLS is a viable tool for ESOL/literacy teaching and learning. Empirical data were collected from students from two ESOL classes in London and their tutor over a ten-week project. In addition to defining the bounds of CALLS, the paper identifies four components as desirable for a pedagogy of CALLS and concludes that CALLS is a viable avenue for operationalising the notion of multi-literacies in classroom practice.
