When you learn to read and write, it opens up opportunities for you to learn so many other things. When you learn to read, you can then read to learn. And it's the same thing with coding. If you learn to code, you can code to learn. Now some of the things you can learn are sort of obvious. You learn more about how computers work.

I started my career as a journalist, writing about science and technology for 'Business Week' magazine. Then I decided to make a career shift. I went to graduate school in computer science, and I began developing educational technologies - in particular, technologies to engage children in creative learning experiences.

As I see it, whoever's doing the inventing is also doing most of the learning - and probably having most of the fun.

I became interested in educational technologies because I believe that they have the potential to transform how we practice and think about education and learning.
