Left: Raw Score-Scaled Score. Center: point differential vs raw-score. Right: Percent increase of scaled score over raw score vs the raw score. In other words, (scaled-raw)/raw * 100%



I believe that mathematics should be taught, not collaboratively explored; algebra and geometry are better than a vague course of Integrated Math; spiraling doesn't work nearly as well as learning it properly the first time; "I don't DO math" should be an incentive rather than an excuse. "I don't DO English" should be treated the same way.
