q2 i? Correlations between LNIRT ability and speed estimates, person-level WCPM scores, and DMT/AVI categories varied between 0.32 and 0.88, all significant at α = 0.001. → van der Velde 2025 q2 i? For predicting DMT and AVI classifications, the speed estimates and WCPM metrics outperformed the ability estimates. → van der Velde 2025 (2)

Evidence¶

van der Velde 2025¶

van der Velde, M., Harmsen, W., Veldkamp, B. P., Feskens, R., Keuning, J., & Swart, N. (2025). Speech Enabled Reading Fluency Assessment: a Validation Study. International Journal of Artificial Intelligence in Education. https://doi.org/10.1007/s40593-025-00480-y

q2 · i? · associational · r2

Extrapolation inference analysis: Pearson and Spearman correlations (Table 5) between LNIRT ability and speed estimates, person-level WCPM measures, and DMT and AVI categories for 653 Grade 2–3 children. The article reports all correlations significant at α = 0.001.

"Correlations varied between 0.32 and 0.88, showing weak to very strong correspondences between the oral reading metrics."

The authors' interpretation in the Discussion of the extrapolation evidence: automaticity-related metrics (speed, WCPM) related more strongly to the DMT and AVI than LNIRT ability estimates, which the authors link to lower variability of accuracy across primary education.

"With regard to the DMT and AVI, the speed estimates and WCPM metrics outperformed the ability estimates."

Discussion¶

Related Claims¶

• SERDA-derived scores classify children into DMT and AVI proficiency classes with moderate to good accuracy and items discriminate moderately well or better — related
• Equated WCPM scores are more highly correlated across passages read by the same student than raw WCPM scores, suggesting greater reliability — related
