Without the models I cannot be sure what, precisely and specifically, each of the key criteria – well-developed, strong ideas, clearly-evident organizational plan, engages the reader, etc. – really mean. I may now know the criteria, but without the models I don’t really know the performance standard; I don’t know how “strong” is strong enough, nor do I know if my ideas are “inappropriate.: There is no way I can know without examples of strong vs. not strong and appropriate vs. inappropriate (with similar contrasts needed for each key criterion.)
