The one I abhorred: Taught correct usage by insisting we learn all the skills of diagramming sentences, and memorize rules like "The predicate nominative (uh, what?) requires the transitive case" (or something like that. She also insisted we make a "poetry scrapbook" of a poet we liked, with a poem or two. We were graded partly on the artistry of said scrapbook. The one I adored: Had us write something, anything: an essay, a poem, a short story--whatever every week. She explained that in cases of "I" did whatever along with someone else ("Joe" perhaps,) you simply remove "Joe" and use that. Example: Joe and (I or me) like RPGs: you wouldn't say "me like, you'd say "I like." So "Joe and I like." She would return the papers with comments in the margins.
