Personalized learning is a big education buzzword these days, and most of the time it means using technology is some sort of magical way so that students can have their own individual learning path.

Pernille Ripp has written an excellent description of what personalized learning can mean in a non-technology way in her post, 6 Changes Toward Personalized Learning.
I’d suggest it really looks like just plain good differentiated instruction in the classroom (see The Best Resources On Differentiating Instruction).
If you want to learn what personalized learning means in the context of all the high-tech, big money, applications, you probably want to check out Education Week’s new big feature, Taking Stock of Personalized Learning.
