1. Plagiarism (Not giving credit where credit is due)
2. Leaving the assignment to the last minute (they can tell!)
3. Inadequate – or non-existent – editing: misspellings,
repetitions, obvious errors
4. Not answering the question
5. Lack of critical thinking
6. Lack of organization: can't put a paragraph together, incomplete
sentence, logical leaps from one paragraph to the next (transitions),
inability to create an outline and follow it
7. Introductions that attempt to shock or use a journalistic style
with shocking emotional quotes or statements or overdramatic claims
8. "Highfalutin" diction: when the words chosen don't mean
exactly what the writer thinks they do, or when a simpler word would
do the job better
9. Blatant generalizations and exaggerations
10. "Research" done entirely on the web without any attempt
to be judicious or critical of the source.
11. Improperly introduced quotations. This almost always breaks the
flow of the sentence, and thus the concentration of the reader.
