Cui bono?

The biggest fad in public education is called "inclusion." It means that stupid kids, immature kids, mean kids, and criminals should all be in the same classes as your kids. This (supposedly) preserves the self-esteem of the defective ones and teaches "tolerance" to the normal ones. What it really does is force teachers to water down the curriculum so that all are working on the same (low) level. These classes are ostensibly "regular" classes but if they are "co-taught" classes, then one of the teachers is the special ed teacher and the other is the regular teacher. These co-teachers are supposed to plan together, teach together, assess together, etc. It's a myth. It is impossible for two teachers to create effective plans for 30 or more kids who range in IQ from 125 to 72. Used to be that there were separate classes for "low" kids, but thanks to the shrill voices of PC and spineless politicians, teachers are forced to rob normal kids of precious time while they try to tame the wild ones or try to remediate the infantile skills of the low ones.
There is NO science to support this "collaborative teaching" effort (retch). Putting like-talented kids together used to be called "tracking" and it ensured that teachers could do the most with the group they had, without worrying about losing the dummies or boring the einsteins. "Teach to the middle," teachers are told. This makes sense in a 20 point IQ spread. It's totally impossible in a 50 point spread.

Parents, beware. If your kid has anything on the ball, keep them out of "co-taught" or "mainstreamed" classes.
