The core concept behind effective instruction is differentiation and adaptation particularly now that technology and digital media is taking over every facet of our life.

Adaptation requires thinking analytically about what goes on when students are engaged in learning. Some get the point so rapidly without the need for exhaustive explanations but others are slow learners and call for longer time.
