In this statement, the author should set out their topic so the reader knows exactly what they are going to be reading about.
In a research paper, a thesis statement should clearly outline what the topic of the essay is and the broad category of facts that will be included.
If you were writing a paper about a war, you wouldn't first start with a major battle, jump back to the causes of the war, jump forward to the outcome of the war, and jump back to explain who was fighting. Any topic you could write about can be clearly organized into a natural progression of ideas and facts.
The example mentioned above would earn a zero in this category on the rubric.
When you are writing a research paper, it is incredibly important that everything you state can be backed up with a source.
For example, if you claimed that the Titanic was painted pink with purple stripes, you would need a source to support that assertion, so readers know you are not just making things up.
The convention of a rubric is often the easiest to grade, as it is merely looking at how many spelling, formatting, and grammatical errors the author made in the paper.
Usually, this section of the rubric will have a clearly defined number of errors for each level of scoring.
This makes the total score for the paper 15 points. These will be: Thesis Statement, Organization of Ideas, Use of Sources, Bibliography, and Conventions.
Any good essay should begin with a clearly written thesis statement.
