Toward a sociocultural approach to computerized dynamic assessment of the TOEFL iBT listening comprehension test.

The current study addressed the impact of computerized dynamic assessment (C-DA) on the TOEFL BT listening comprehension test administered to Iranian EFL learners ( = 185) who took part in preparation courses on the TOEFL exam in some language centres in Iran. To mediate the test-takers with hints to process the listening questions, a computer software program was developed, and it was meant to produce the following: Actual, mediated, and learning potential scores. Findings of the study indicated that the actual and mediated scores led to significant different mean scores in various listening ability levels in almost all question types. Generally, results highlighted the significant positive impact of C-DA on improving EFL test-takers' performances in the monologue and dialogue tasks. Teachers were recommended to implement C-DA since the information gained from this sociocultural assessment mode empowers them to provide learners with more individualized and accordingly more effective teaching and assessment strategies.
