Promoting low-income preschoolers’ school readiness through a text messaging intervention

ABSTRACT The aim of the study is to evaluate the effects of a language-rich math content text message intervention as a way to promote child literacy outcomes for children enrolled in 15 Head Start centers participating in Jumpstart. Two-hundred and fifty-eight families were randomly assigned to treatment (language-rich math text) or control (information about kindergarten enrollment) conditions. Families received text messages in English, Spanish, or written Chinese. Parents reported on children’s fall entry skills and family demography. Teachers reported on children’s interest in math and literacy. Children were directly assessed on literacy skills to determine if the language-rich math content increased literacy skills. Structural equation models reveal no main effects for the sample of 258, but subgroup analyses by language show intervention effectiveness. For families receiving text messages in English, effectiveness depended on children’s fall letter and shape knowledge for increasing phonological awareness (English). The intervention appears most effective for Spanish-speaking families by increasing children’s math and literacy interest, definitional vocabulary, and print knowledge. Limitations and finding implications are discussed.
