No one can remember random factoids.
To remember knowledge and information, we need a schema.
from the Brookings report Barry linked to:
"There is strong evidence that the choice of instructional materials has large effects on student learning—effects that rival in size those that are associated with differences in teacher effectiveness. But whereas improving teacher quality through changes in the preparation and professional development of teachers and the human resources policies surrounding their employment is challenging, expensive, and time-consuming, making better choices among available instructional materials should be relatively easy, inexpensive, and quick."
