In a traditional classroom, a teacher can hope to reach (at best) half of his or her student’s specific educational needs during a given lesson.
There are bound to be students who are above and below the academic level of the content. For me, that was math. Algebra was a miserable experience, as I was woefully behind my peers and didn’t get the support I needed.
Today, there’s a movement to individualize learning. Intentionally using computers and other technology empowers teachers to bring students exactly what they need, when they need it. This is revolutionary compared to the past few hundred years of public education – a “factory” model where teachers aren’t given much room to differentiate for each learner.
