Your professor wants to see you work through complex ideas and deepen your knowledge through the process of producing the paper.
Each assignment—be it an argumentative paper, reaction paper, reflective paper, lab report, discussion question, blog post, essay exam, project proposal, or what have you—is ultimately about your learning.
The reader experiences no interruption to the flow and understands how each concept or topic connects to the previous one.
Most of the writing uses transition statements well so the writing flows from section to section and paragraph to paragraph.
Wikipedia, Dictionary.com, and mainstream news articles have not been used in the references and citations.
Nearly all referenced works are peer-reviewed, authoritative sources which have an author(s).
Academic papers, in which scholars report the results of their research and thinking to one another, are the lifeblood of the scholarly world, carrying useful ideas and information to all parts of the academic corpus.
Unless there is a particular audience specified in the assignment, you would do well to imagine yourself writing for a group of peers who have some introductory knowledge of the field but are unfamiliar with the specific topic you’re discussing.
But college papers aren’t written like letters; they’re written like articles for a hypothetical group of readers that you don’t actually know much about.
There’s a fundamental mismatch between the real-life audience and the form your writing takes. It helps to remember the key tenet of the university model: you’re a junior scholar joining the academic community.
