The Relative Impact of Aligning Tier 2 Intervention Materials with Classroom Core Reading Materials in Grades K-2
Foorman, Barbara R.; Herrera, Sarah; Dombek, Jennifer
Elementary School Journal, v118 n3 p477-504 Mar 2018
This randomized controlled trial in 55 low-performing schools across Florida compared 2 early literacy interventions--1 using stand-alone materials and 1 using materials embedded in the existing core reading/language arts program. A total of 3,447 students who were below the 30th percentile in vocabulary and reading-related skills participated in the study. Both interventions were implemented with fidelity for 45 minutes daily for 27 weeks in small groups of 4 students (or 5 in grade 2). The stand-alone intervention significantly improved grade 2 spelling outcomes relative to the embedded intervention; there were some differential impacts due to cohort and baseline and, in kindergarten, to English-learner status. On average, students in schools in both interventions showed similar improvement in reading and language outcomes and similar percentile gains to those in recent systematic reviews. Results are discussed with respect to alignment of Tier 2 instruction with Tier 1 instruction.
