So here I am reading the newest issue of Educational Leadership - pretty standard fare for a rainy/snowy Sunday morning. This issue focuses on the (non/mis)use of data. Please turn to page 20 and read the first sentence of the first full paragraph.
I'll wait for those of you who need to get a subscription first.
It reads "Research has emphasized that data disaggregation is essential to effective data use (Johnson, 2002; Lachat&Williams, 2003)."
So (and I hate to have to be the one to point this out), it took 2 studies to show that data needs to be diaaggregated for it to make sense. Are you hearing me? Two NON-DISAGGREGATED studies provided the data showing the need for disaggregation! Why aren't people up in arms about this? My thumbs hurt. I should only become indignant near a full-sized keyboard.
