"We have a wealth of studies demonstrating the power of active teaching, especially for children who struggle to learn to read and write. But expert teaching requires knowing not only how to teach strategies explicitly but also how to foster transfer of the strategies from the structured practice activities to students' independent use of them while engaged in reading. A real concern is that, when instruction becomes too explicit, children never learn when and how to use the strategies profitably and successfully in their independent reading."
