Again , as a public urban high school Social Studies teacher I have an opportunity to see what you describe firsthand only it is actually worse. As much as classical literature is short shrifted , grammar is slighted even more. When many of these children attempt to write the result often indicate that they are uneducated. I teach 11th and 12th graders. Kids should know how to spell basic words at this level yet I have to spend precious time in remedial effort at the expense of content, just so they can understand the most rudimentary points. It's frustrating my friends.
