Learners placed at the same CEFR level by DIALANG differ in their ZPDs, which DIALANG's non-dynamic feedback does not capture¶

Subclaims¶

q2 i? Two learners at the same CEFR A2 level for English structure showed different reciprocity levels and mediation needs, revealing ZPD differences that DIALANG's psychometric results did not pinpoint. → Ebadi 2016

q2 · i? · qualitative · r2

Qualitative microgenetic case study of two Iranian university students, both placed at CEFR A2 by DIALANG's structure section. The author reports that "their reciprocity levels and required me diation revealed important information" about actual differences in their ZPDs for modals, which the non-dynamic test missed.

"a lthough both Sarah and Dena were at the CEFR’s A2 level for English structure and both coul d not produce modals correctly before mediation, their reciprocity levels and required me diation revealed important information"

Discussion¶

Related Claims¶

• Dynamic assessment reflects young children's learning potential more accurately than static tests, especially with minority and learning disabled children — the general claim this finding bears on, with the studies behind it
• Interactionist DA mediation in SCMC reveals learners' microgenetic movement through internalization levels within the ZPD — related
• Learners at the same proficiency level differ in responsiveness to mediation, with Sarah needing less explicit help than Dena — possibly the same claim (merge candidate)
• The mediational strategy is reported as more effective than other intervention approaches such as the graduated prompt — related
• Static individual assessment misses developing functions; ZPD-based assessment reveals potential competencies — a broader claim this one bears on
