This project provided a means for parents—particularly mothers—to support their children’s literacy acquisition through the use of content delivered via mobile phone. In 2013, the implementing organization, Urban Planet, Inc., developed and delivered audio-enabled Short Message Service (SMS) messages to mobile phones of participants in the pilot program. The messages were designed to enable parents to engage in simple literacy-promoting activities with their children, such as practicing letter sounds, building words, and listening to stories. RTI measured the effects of the program by comparing pre- and post-test scores on a simple reading diagnostic with those of a control group (parents were only given verbal instructions once regarding actions they could take to help their child) and a group receiving the same content but in a printed booklet.
