Pilot test of the Hablemos Juntos Tier 2 academic language curriculum for Spanish-speaking preschoolers

Abstract This randomized control trial evaluated the feasibility and promise of a Spanish supplemental curriculum when delivered in small-group settings to pre-kindergarten (pre-k) children who qualified for Tier 2 support. The program focused on Spanish academic language development using shared book reading and extension activities. All 30 classrooms served Spanish-speaking students within a dual language Spanish/English model. The 167 participating students were eligible for Tier 2 support based on scores below benchmark on their district’s screening and progress monitoring measures. Classroom teachers provided about 15 h of Tier 2 intervention across an 11-week period. Results showed effects on proximal outcomes, but not distal, standardized measures. Specifically, children in Tier 2 intervention groups learned explicitly taught academic vocabulary words (d = .50), but there were no group differences for untaught words exposed within the shared reading texts. Classroom teachers were able to implement the Tier 2 intervention with fidelity and reported high satisfaction with the approach. These findings suggest the promise of small-group instruction for targeting higher level, academic language with pre-k children demonstrating risk.
