A research paper assignment on The Screwtape Letters differs substantially from a standard close reading or thematic analysis essay, since it asks students to bring outside sources into conversation with the primary text rather than relying solely on their own independent interpretation. This kind of assignment works particularly well for advanced high school or college students who have already demonstrated solid foundational analytical skills with the novel and are ready to situate their reading within a broader scholarly, historical, or theological context. Choosing the right research topic, and communicating clear expectations for how outside sources should be integrated, makes the difference between a genuinely rigorous research paper and a padded essay with citations attached.

Strong research topics for this novel tend to fall into a few productive categories: historical context research examining the book's 1942 wartime publication and its relationship to Lewis's own experiences and the broader cultural moment, theological research situating the book's arguments within the specific Christian tradition Lewis drew upon, and literary-critical research engaging with published scholarship on Lewis's use of satire and allegory. Each of these categories asks students to develop genuinely different research skills, and teachers should be clear about which category a given assignment expects, since the appropriate sources and citation practices differ considerably between historical, theological, and literary-critical research.

A well-scoped research topic within any of these categories should be narrow enough for a student to genuinely master the relevant sources within the assignment's time frame, rather than so broad that any research paper on the subject would necessarily remain superficial. A topic like "how Lewis's own wartime experiences in England shaped the specific fears and anxieties reflected in the later letters" gives students a focused, researchable question, while a topic like "C.S. Lewis and Christianity" is far too broad to support genuine depth within a typical student research paper's scope and length.

Sample Research Topics Across Different Categories

Historical research topics might examine how the specific details of wartime London, including air raids and rationing, appear in the later letters and what this reveals about Lewis's intentions for reaching a contemporary wartime audience with his theological argument. Theological research topics could explore how Screwtape's specific errors about human psychology and virtue relate to particular strands of Christian thought Lewis was familiar with, whether drawing on medieval theology, his own Anglican tradition, or contemporaries he was in direct conversation with, such as fellow Inklings member J.R.R. Tolkien.

• How Lewis's own wartime experiences in England shaped specific details and anxieties in the later letters
• The relationship between Screwtape's flawed theology and specific strands of Christian thought Lewis engaged with directly
• How the novel's initial publication as a serialized column shaped its structure and pacing across individual letters
• Critical reception of the novel upon publication and how that reception has shifted across subsequent decades
• Comparing Lewis's use of satire in this novel to his use of allegory in the later Chronicles of Narnia series

Grading Criteria Specific to Research-Based Writing

Grading a research paper requires attention to criteria that a standard literary analysis essay rubric typically does not address, including the quality and credibility of chosen sources, accurate integration and citation of those sources, and genuine synthesis between outside research and the student's own original analysis of the primary text. A common weakness in student research papers involves sources that simply sit alongside the student's own analysis without genuine integration, producing an essay that reads as two separate, loosely connected pieces rather than a single coherent argument informed by research. A rubric line specifically assessing this integration catches a genuine and common weakness in student research writing.

Source quality also deserves explicit rubric attention, since students researching a topic like this one may encounter a wide range of source credibility, from rigorous academic scholarship on Lewis's work to more casual, less reliable online commentary that happens to appear prominently in a basic search. Teaching students specifically how to evaluate source credibility for this particular topic, perhaps by providing a curated starting list of reputable Lewis scholarship, helps ensure the research paper assignment builds genuine research literacy skills rather than simply testing a student's ability to locate any source that seems relevant to their chosen topic.

Balancing Primary Text Analysis With Secondary Research

One risk specific to this kind of assignment is that students become so focused on synthesizing outside research that their own direct engagement with the primary text, the actual letters themselves, becomes thin or secondary within the final paper. A strong research paper on this novel should still demonstrate the same close reading and irony recognition skills expected in a standard literary analysis essay, with research serving to deepen and contextualize that primary analysis rather than replacing it entirely. A rubric that explicitly requires a minimum number of direct citations from the primary text itself, alongside outside research sources, helps maintain this necessary balance.

Feedback on research papers should address both dimensions explicitly, noting separately how well a student handled their research sources and how well they maintained genuine primary text analysis throughout the paper, since these represent genuinely distinct skills that a single holistic grade tends to obscure. A student who excels at primary text analysis but struggles with source integration needs very different guidance than a student who handles research skillfully but loses touch with genuine close reading of the novel itself, and specific, separated feedback helps each student understand exactly where to focus their revision efforts.
