What a curriculum contains has historically had far less impact on instructional practice than is widely thought. But curriculum's modest influence on instruction has been dramatically transformed in the past few years, especially with respect to state-sanctioned curricula.

In standardized testing, the paradox crops up when you try to calculate national average scores for both the SAT and NAEP.
