If used effectively, rubrics can help improve students' writing.
Each cell of the rubric describes a specific aspect of writing at a specific level. Transitions are mature and graceful. Sufficient background information is provided.
Writing is confusing, hard to follow. There is a clear distinction between general observations and specifics.
How can you identify an error if you commit the error? Do readers have to re-read a sentence multiple times to understand it? Introduction creates interest. Now you have a sense of your writing score. The writer shares some information, facts and experiences, but may show problems going from general observations to specifics.
Taking a break between writing your essay and evaluating it will help to give you a more objective eye. Thesis states the position or belief.
