Ken Macrorie has for years been campaigning for the prohibition of instructors' "blood in the margins" of their students' freshman themes.! His admonition that marking all the weak points can easily discourage a student came immediately to mind when I was reading my first set of freshman papers this fall. One paper was so marred with fundamental stylistic errors that had I bloodied it with chicken scratches the paper would have been almost completely red. There would have been at least fifty marks and the paper totalled only about 500 words.
