What Is Smart Kidz Club?
Smart Kidz Club is a digital library of original, exclusive books developed by Smart Kidz Club itself. Most of the books are knowledge based, covering science, history, biographies, space, nature, and the world around us, across more than 40 categories. Every book is narrated in a real, expressive human voice and paired with activities and quizzes. The whole library is ad-free and private, and downloaded books work offline. There is no autoplay and no infinite scroll. After a story the child pauses, does a comprehension activity, then decides what comes next.
The Problem We Solve
More than 250 million children worldwide cannot read. In the United States, 66 percent of children cannot read proficiently by fourth grade. Children who are read to at home hear about a million more words before kindergarten than children who are never read to. Smart Kidz Club exists to close that gap, by making high quality books easy to reach at home, in school, and anywhere a child can listen and read along.
The "Just Right" Method
Not every screen helps a child read. In a 2018 study, Dr. John Hutton, a pediatrician who studies early literacy, showed four year olds the same story in three forms and watched their brains in an fMRI machine. He called what he found the Goldilocks Effect.
"Just Right": Narrated Picture Books
A real human voice with still pictures gave the highest comprehension. Children were challenged the right amount and learned the most.
Too Hot: Animation
Moving cartoons overstimulated young minds. The brain worked hardest, yet understanding of the story was lowest.
Smart Kidz Club books follow the "Just Right" method: a real human voice, still pictures, and no animation, video, or games to pull a child away from the story.
The Research Behind It
- The Goldilocks Effect. Hutton and colleagues, 2018 and 2019: narrated picture books are the "Just Right" form of digital reading.
- The four pillars of learning. Hirsh-Pasek and colleagues, 2015: deep learning needs active, engaged, meaningful, and socially interactive design.
- The million word gap. Logan and colleagues, 2019: children who are read five books a day enter kindergarten having heard about a million more words.
- Expressive versus robotic narration. Westlund and colleagues, 2017: children pay more attention, remember more, and use more new words with an expressive human voice than with a flat robotic voice.
- Shared reading. Mendelsohn and colleagues, 2018: reading aloud together builds language, listening, and attention, and helps behaviour.
- Picture books and vocabulary. Massaro, 2015: picture books are two or three times more likely than everyday talk to use words outside the 5,000 most common words.
How We Are Different
Our books are original and exclusive to Smart Kidz Club, and most are knowledge based. Every book is narrated in a real, expressive human voice, never a robotic voice. There are no ads, no autoplay, and no infinite scroll. Children choose their own books, earn rewards, and read with a parent or teacher, so reading stays active, engaged, meaningful, and socially interactive.
