Purpose: Literacy 3D is an enhancement of Tier 1 literacy instruction for the purpose of increasing and sustaining teacher’s literacy focus through Professional Development combined with ongoing Practice-Based Coaching (PBC), data-based feedback, and 10 evidence-based teaching strategies. Literacy 3D is a fully developed supplemental and enhanced instructional intervention consisting of 5 two-hour literacy focused (i.e., comprehension, vocabulary, etc.) workshops for teachers held at their school. Our purpose is to evaluate the efficacy of Literacy 3D intervention relative to “business as usual”.

Project Activities: 120 teachers and 2,160 children with/without Individual Education Programs and who are Dual Language Learners will participate. A waitlist randomized control trial with four waves of data collection per year and then a year of follow-up data collection (4 times) will be used. Teachers will be randomized. The experimental group will receive Literacy 3D in year 1 and be assessed for sustainability in year 2. After BAU in year 1, the waitlist group will receive Literacy 3D in year 2. Teacher and child outcomes are both published and researcher developed measures including: sociodemographic and descriptive surveys, GRTR screener (English, Spanish), classroom instructional quality, implementation fidelity, dosage measures, proximal change in teacher literacy focus and child engagement (CIRCLE), formative growth in early literacy skills (PELI), summative language and literacy test outcomes (TOPEL, Pre IPT Oral Language [English, Spanish]), teacher satisfaction, and program costs. The primary analytic method will use Multilevel Modeling Models will include students at level 1 and classrooms/teachers at level 2. The analysis will test primary experimental and secondary moderation effects to confirm the integrity of treatments implemented, among other moderating influences of interest (e.g., child characteristics, IEP, DLL, etc.). Literacy 3D, findings, and the study database will disseminated broadly via peer-reviewed publications, a website, professional publications, and social media.
