As I pointed ou...I enjoyed your bog post very much! As I pointed out for years to my students, and to the public... always look at cohorts, since looking only at grade level changes year to year can often be explained by demographic shifts, while the "diagonals" (moving from one grade to the next each year in a chart) can give us much more valuable and realistic insights. One other thing that would be useful, if you don't mind a suggestion, would be to com are gains over time (as you do) with the average gains over time for the state as a whole, for example. I remember sharing with my University students some "marketing" data that suggested that certain commercial products" were extremely successful in creating student improvement... when they compared the data provided with state-level growth my students discovered that the schools using the products (regardless of how much credit or blame you give to them" actually showed fewer and less substantial gains that schools that had NOT used the products. Thanks for sharing. i am gong to retweet this! :)Noel Hammatthttps://www.blogger.com/profile/01027807400033489793noreply@blogger.com
