My AP English teacher, who is also the English Department Chair for the school district, often talks about how we're not being taught proper grammar. She says that the problem is that most teachers find grammar utterly boring, but she really enjoys it. She frequently lambastes us about grammatical errors. The problems that she finds aren't usually spelling (that's fixed by computer spell checks now) but errors like comma splicing, quoting, sit/set, lay/lie type things. I agree it's a major problem and is quite annoying, but I think, as with other educational problems, parental involvement is needed.
