It’s not the amount of data, it’s if the data is useful in teaching.

1)      More data is not necessarily a good thing.

  1. Useful data is given to teachers about their students in a time frame that allows them to do something with it to help students learn.
  2. Navel-gazing about SOL data from last year is not very much help in a school with a 25 percent student mobility rate and the fact that the 75 percent of the student who actually stay change so much in 6 months the data is almost useless.
  3. Useful data comes to the teachers during the window the stuff is still being taught, and the data should reflect what the kid is supposed to know, and should be delivered in a manner that doesn’t take a lot of effort to analyze.
