From Dan Meyer:
But the very technology that lets Khan Academy assess hundreds of concepts at global scale — random number generators, string splices, and algorithmically generated hints — has downgraded, perhaps unavoidably, what it means to know math.
I hope Dan realized the full weight of his words. Technology (all technologies) give and take away. While it’s easy to be critical of the Khan Academy technologies, I hope we learn to be critical of all the technologies we use in education.
