Investigating the Effects of Using Dynamic Assessment Procedures on the EFL Learners’ Vocabulary Knowledge Development

This study seeks to provide insights into the process of vocabulary learning and promoting vocabulary knowledge by tracking its development in dynamic assessment (DA) procedures through thematic and microgenetic analysis. In order to meet the aim of this study, three male and three female EFL learners were chosen nonrandomly based on their availability. All the participants were beginners with regard to their vocabulary knowledge. The participants voluntarily attended 15 DA sessions throughout each session a few new vocabulary items were presented using different techniques of teaching vocabulary. The participants received corrective feedback within their zone of proximal development (ZPD). They were provided with appropriate levels of help by moving gradually and using prompts through the regulatory scale from the most implicit to the most explicit assistance which emerged from the individualized mediation between the mediator and the learners. The results of the study indicated that using DA procedure can enhance the development of vocabulary knowledge among EFL learners.
