Researchers at the University of California at Irvine have found that some mobile apps claiming to help young children learn may not be designed to teach them in the ways they need, according to a study that reviewed 171 math and literacy apps. Josh Golin, executive director of the nonprofit Campaign for a Commercial-Free Childhood, says many apps are marketed as educational even though their claims lack evidence. This is a reminder to research apps before downloading or purchasing for your young kids.
