Nearly 1/3 of kids in the US have access to a tablet, and usage is increasing rapidly. Kids are using tablets frequently, with 60% using them 4 or more times per week. The most common activities are games, reading or listening to stories, looking at pictures, and watching videos. Parents view educational apps as those that promote problem solving, creativity, and 21st century skills over traditional educational factors. They want apps to assess reading progress and provide reading level information. Effective e-book design incorporates interactivity, customization, and navigation features optimized for kids.
