Mediating Iranian EFL Learners: Private Speech and Scaffolding in Reading Comprehension

Ali Rahimi, Soheila Tahmasebi


In Sociocultural Theory (SCT), mediations in second language learning include (1) mediation by others (2) mediation by self (3) mediation by artifacts, which incorporates brilliant insights for EFL contexts (Lantolf, 2000a).
