When I was growing up, my parents despaired about my refusal to open a book. They sought out doctors and teachers, convinced I had some kind of learning disability. Finally, someone worked out that the problem was not reading, but rather what they were giving me to read: I was bored with the picture books. Taking a personalized approach to teaching kids to read has long been a challenge for traditional educators, but is now within reach with new technologies like LightSail Education, an award winning literacy platform for K-12. I spoke with its founder and CEO, Gideon Stein, about how data and adaptive learning is changing the classroom, and why literacy, even in this digital age, remains a foundational skill.
