Informational text--resources whose purpose is to inform--is essential to daily life and fundamental to literacy. Unfortunately, young children typically have limited exposure to informational text. Two 9-week randomized controlled trials with 263 first-grade children from low-income communities examined whether free educational videos and digital games supported children's ability to use informational text to answer real-world questions. Participants received Internet-enabled tablets and were randomly assigned to condition. Study 1 found significant positive intervention impacts on child outcomes; Study 2 replicated these findings. Combined analyses demonstrated primary impact on children's ability to identify and use structural and graphical features of informational text. Results are discussed in the context of the scalability of educational media to support informational text learning.
