Resumen de What’s in a ZPD?: A case study of a young ESL student and teacher interacting through dialogue journals

Hossein Nassaji, Alister Cumming

• Aiming to provide a case-study account of features of the ZPD (zone of proximal development) in language teaching and learning, we analysed 95 exchanges in interactive dialogue journals written over 10 months between a 6-year-old Farsi speaker beginning to learn English and his Canadian teacher. Using a scheme of language functions developed by Shuy (1993), we show how the teacher and student constructed and sustained a long-term written conversation involving intricate patterns of complementary, asymmetrical scaffolding. We interpret the findings to suggest the value of analysing language learning and teaching as integrally unified, interactive phenomena. We suggest questions worthy of future research into features of the ZPD in language teaching and learning.
