This paper evaluates the affordability of Quipper as an online platform for teaching and learning English as a foreign language (EFL). It focuses on the extent to which features available in Quipper may correspond to fundamental components of Computer-Assisted Language Learning (CALL) pedagogy, as suggested by Chapelle (2003), including L2-input exposure, interaction and linguistic production. The evaluation results indicate that Quipper is affordable for use as an online teaching and learning EFL platform. More importantly, it corresponds to the three conditions of CALL pedagogy, thus making it a potential aid for activities used in teaching and learning foreign language.
