Grading Literary Research Papers That Use Secondary Sources on C.S. Lewis
Published on September 30th, 2026 by the GraideMind team
A research paper on Till We Have Faces asks students to do something different from a standard literary essay. They must read what critics have said about Orual, Psyche, or Lewis's use of myth, and then enter that conversation with an argument of their own. The challenge for graders is separating papers that engage with sources from papers that simply decorate an opinion with borrowed quotations.

The most common weakness is source stacking, where each paragraph introduces a new critic and summarizes their view without connecting it to the others. The paper reads like an annotated bibliography, and the student's own voice almost disappears. Strong papers use sources selectively, placing them in conversation with each other and with the student's reading of the novel. Pointing this out early, ideally at the annotated bibliography stage, gives students time to restructure instead of just trimming.
A rubric for research papers should therefore separate the use of sources from the quality of the argument. A student might find excellent sources and still fail to build a claim, or make an original argument supported by only one weak source. Distinguishing these problems lets the feedback point to the right fix instead of delivering a vague complaint about depth.
What Good Source Integration Looks Like
Strong papers treat critics as voices to respond to rather than authorities to defer to. A student might summarize a critic's view of Orual as a tragic figure, explain what that reading gets right, and then argue that it overlooks the second part of the novel. That move, agreeing in part and then pushing further, is the heart of scholarly writing and deserves clear recognition in the rubric.
- Sources are introduced with a clear sense of who the critic is and what they argue
- The student's own claim remains the organizing idea of the paper
- Critics are used to support, complicate, or challenge the student's reading
- Quotations from sources are brief and explained, not dropped in without comment
- Citations follow the assigned style consistently and accurately
A good research paper uses sources to sharpen the writer's argument, not to replace it.

Students often rely on whichever sources appear first in an online search, which can include study guides and unsigned summaries. The assignment should specify what kinds of sources count, such as peer-reviewed articles, scholarly books, and edited collections, and the rubric should check this requirement. Giving students a short list of recommended databases or a librarian visit saves everyone frustration later.
Checking sources takes time, but a quick scan of the bibliography usually reveals the pattern. If a paper cites only websites with no authors, a short comment about source quality is warranted, and the student should be given a chance to replace them. Teachers who do this early in the process, at the proposal or annotated bibliography stage, avoid discovering the problem on the final draft.
Scaffolding the Process to Make Grading Easier
Breaking the project into stages makes both the writing and the grading more manageable. A proposal, an annotated bibliography, an outline, and a draft each give you a chance to catch problems when they are still small. Each stage can be graded lightly, with focused feedback, so that the final paper is a refinement and not a surprise. Staged grading also discourages last-minute writing, which is where most citation and source problems begin.
Students also benefit from seeing the rubric before they begin and from having a model paper to study. A strong example, even a short one, shows how a writer introduces a critic and responds to the argument. That model does more to improve source use than any number of comments on a finished paper. Even a published student paper from a past semester, with your annotations, can serve the purpose.
Making Research Paper Grading Sustainable
Research papers are long, and a professor with seventy of them faces a real time challenge. Using the rubric rows to structure the reading, checking the thesis and sources first and then the argument and style, keeps the process organized. Many graders find that they can place a paper in a band within the first few pages and spend the remaining time confirming and writing comments.
AI-assisted grading can support this by checking that citations are present, that each source is used in the body, and that the claim is supported throughout. The tool's output is a starting point for the teacher's own judgment about the quality of the argument. It frees the grader to focus on the intellectual substance of the paper, which is the part students most need an experienced reader to evaluate.
