The Khan Academy already has a million users learning everything from basic math to trigonometry and beyond, it can serve a few million more. Imagine a world where you child does homework in class and watches lectures at home, at their own pace whenever they want. They can rewatch old lectures to relearn things and they can pause it whenever they need to. Now, all the time in class is spend with individual students. Welcome to the future of education.
As a professor I think this is a great twist in the classroom paradigm. This allows more time to be spent with each student helping them individually. There are tools and dashboards that allow a teacher or mentor to see what exercises a student has done, what they struggled with, and what they know. Using this you can even ask a student who gets it to help a struggling student as the first to respond and assist.
Best of all, it’s FREE and on the internet so anyone in the world can be a student. Your kids can be helping tutor children in Africa. You can be a mentor to others in your field and you too can learn from literally thousands of topics. With groups Khan Academy and Wikipedia we can get one step closer to making quality education available to everyone.
