Project Description: This is a small randomized controlled trial of LENA Grow, a language-based coaching program for early childhood teachers designed to improve communication skills. The study randomly assigned 20 early childhood teachers to receive the coaching program or to a usual services control group. This reports on teacher perceptions of language development, job satisfaction, and self-efficacy, and a range of outcomes related to interactive language between teacher and child for the children in the respective teachers’ classrooms across a 10-week follow-up period.
Key Findings: The current study aimed to evaluate the efficacy of LENA Grow. Results indicated that there were three main findings. First, Grow teachers increased their conversational turns after participating in the LENA Grow program that included individualized coaching. Second, Grow teachers increased their job satisfaction compared to non-Grow teachers. Third, children who participated in LENA Grow significantly increased their language and literacy skills compared to children in non-Grow classrooms.
