Science, Technology, Engineering, and Mathematics (STEM) has received widespread attention worldwide and technology companies designed educational applications (apps) focusing on STEM. Young children have access to tablets and smartphones and they engage with a variety of apps every day. Prior research showed that young children learn from…

Over half of educational apps on mobile-app markets are for preschoolers, but little research has examined whether the designs of preschool apps are truly educational.
