APP Guideline: Screen time for children
The new guidelines, especially for very young children, shift the focus from WHAT is on the screen to WHO else is in the room. And in doing so, they raise some intriguing points about the future of learning from media.
For infants and toddlers, age 15 months to 2 years, there is limited evidence from a couple of very small studies that they can learn new words from educational media, if and only if parents are watching alongside them, repeating what the video says and/or drawing attention to what is on the screen. In other words, treating a video or an app like a picture book is the best bet.
The flip side of this is that many studies, including this one, have actually shown poorer language skills correlated with earlier solo viewing of "educational" videos. There is also research that shows language delays in children who watch more TV and start watching earlier. In both cases, the problem seems to be media replacing interaction with people. For this reason, the new AAP guideline has changed from "avoid all screens under age 2" to "avoid solo media use in this age group."
For preschoolers age 2 to 5, there is more evidence that they have the ability to transfer knowledge from screens to the real world, including early literacy and math, and positive social and emotional skills and behaviors.
But the AAP has a strong brand preference here. It names Sesame Workshop and PBS as two trusted makers of evidence-based children's educational media, whereas of an estimated hundred-thousand "education"-branded apps in the iPad store, very few have been found to satisfy high standards for learning.
For this age group, AAP recommends no more than an hour a day of screen use. And, just as with younger children, it wants caregivers to take part in screen time:"Co-view with your children, help children understand what they are seeing, and help them apply what they learn to the world around them."
