NEW YORK: Using mobile apps in preschool classrooms may help improve early literacy skills and boost school readiness for children, according to new research.

"Guided use of an educational app may be a source of motivation and engagement for children in their early years," said Susan B Neuman, professor at New York University and the study's author.

"The purpose of our study was to examine if a motivating app could accelerate children's learning, which it did," said Neuman.

The average time young children spend using electronic devices has more than tripled in the last five years.

Nevertheless, there remains a disparity in access to mobile devices and other technology for low-income children.

In a recent study, 49 per cent of middle class children reported downloading an app, 80 per cent of which were educational, while only 30 per cent of low-income children downloaded an app, 57 per cent of which were educational.

This "app gap" was the focus of Neuman and co-author Carolyn Strom's study.

Recognising that the preschool years are formative in developing children's use of media, the researchers designed a study to examine the effectiveness of an educational app called Learn with Homer on low-income preschoolers' school readiness skills.

The app engages children in a systematic program that integrates word sounds and storybook reading.

The study was conducted in 10 Head Start classrooms with a total of 148 preschoolers.

Children were randomly selected to use either Learn with Homer or an art and activity app. The preschoolers engaged with the apps for 10 to 12 minutes daily, guided by moderators during the 10-week study.

Using several tests of early literacy, the researchers measured changes in children's phonological awareness as a result of daily uses of Learn with Homer, compared with the control group using the other app.

Phonological awareness is the ability to detect sounds that make up words, and is an important predictor of later reading ability.

The researchers found measurable growth in phonological awareness and understanding the connections between speech and printed letters for the group using the Learn with Homer app, compared with the group using the art and activity app. They also observed significant differences in print concepts.

"Given the importance of phonological awareness and how it contributes to school readiness, using digital resources in a highly controlled setting, like a classroom, may substantially help to close the 'app gap,'" Neuman added.
