A Written Language Intervention for At-Risk Second Grade Students: A Randomized Controlled Trial of the Process Assessment of the Learner Lesson Plans in a Tier 2 Response-to-Intervention (RtI) Model

Hooper, S. R., Costa, L. C., McBee, M., Anderson, K. L., Yerby, D. C., Childress, A., & Knuth, S. B. (2013). A written language intervention for at-risk second grade students: A randomized controlled trial of the process assessment of the learner lesson plans in a tier 2 response-to-intervention (RtI) model. Annals of Dyslexia, 66(1), 44–64.

The study examined the effects of Process Assessment of the Learner (PAL), a writing expression curriculum. The program was tested with second grade students in a suburban–rural school district in the southeastern United States. Three sections of PAL lessons were implemented in the district as a small-group curriculum supplement — Talking Letters, Spelling, and Handwriting and Composition. The study found that the average written expression skills of the PAL intervention group were higher than those of the comparison group at the beginning of third grade. However, a review of the findings by What Works Clearinghouse did not confirm that the observed effect of the PAL intervention on growth in written expression skills was statistically significant.
