[quote=Anonymous]The memo that came out discussing the test cheating says that "the raw erasure data for the Erasure study was supplied by CTB and the actual analysis was conducted by the American Institute of Research (AIR). The study concentrated on Wrong-to-Right (WTR) erasures on the 2008 CAS answer sheets. The AIR analysis used two statistical test to determine if the number of WTRs was significantly greater than what would have been observed if there was no teacher manipulation. The study covered both reading and math. There are 191 teachers representing 70 schools that are implicated in possible testing infractions by the study." While Councilman Catania says he doesn't want to investigate further, I just want to see the Study. Which were the 70 schools? How many classrooms in these schools had wrong-to-right erasures? It looks like that work has already been done.[/quote]
