I remember discussions of the California experience that blamed the lack of an improvement in schools when class-sizes were reduced to that problem.<BR/><BR/>Dewey's own figures show that an experienced teacher (3-5 years of teacher experience) is worth about a 7.2% - 9.1% of a standard deviation impact on math achievement (though there may be an endogeneity problem - teachers may be more likely to stick around for at least 3-5 years if they're naturally good at the job anyway). <BR/><BR/>Engelmann's results from DI experience implies that to some extent Dewey's suggestions are a side-show, you can get great improvements by teaching average teachers the tools to do their job well.Tracy Whttps://www.blogger.com/profile/08999246551652981965noreply@blogger.comtag:blogger.com,1999:blog-7691251033406320222.post-67146457247397177772007-03-27T17:16:00.000-07:002007-03-27T17:16:00.000-07:00The merits of class size reduction cannot be discu...The merits of class size reduction cannot be discussed without taking into account the quality of the student body. With well-behaved and motivated kids, it's less of an issue. With a room full of the behavior disordered -- a common occurrence in big city schools -- it's a huge issue.<BR/><BR/>A cheaper alternative to class size reduction would be to segregate the dysfunctional. It's unconscionable to allow a handful of miscreants to prevent those who want to learn from learning. But entrenched egalitarian ideology throws roadblocks in the way of this sensible solution.<BR/><BR/>++++++<BR/><BR/>Help desk:<BR/><BR/>When I upgraded my blogger I wiped out my blogroll and related info (e.g. sitemeter).
