And Then There Were None turns up in college courses on detective fiction, twentieth-century British literature, popular genre, and first-year composition. It is accessible, but it also supports serious analysis of morality, narration, and genre conventions. Professors who use it often assign short analytical papers.

The challenge is scale. A lecture course with a hundred or more students can produce a mountain of papers, and teaching assistants may grade with different standards. Students then receive uneven feedback.

College-level grading also has to balance depth and efficiency. Students expect meaningful comments, but no instructor can write a page for each paper. The trick is to focus effort where it matters most.

A few strategies help keep quality high as numbers grow. They work for a solo instructor and for a team with several graders. Start with shared standards.

Set Shared Standards Early

If several graders are involved, hold a norming session before the first paper. Everyone scores the same three essays and discusses differences. This takes an hour and prevents weeks of inconsistency.

• Provide a rubric with descriptive levels, not just point values
• Share anchor papers that show what each level looks like
• Meet with graders midway to compare borderline cases
• Record common comments in a shared bank
• Tell students how the rubric maps to the course grade

Focus Comments on Higher-Order Concerns

In a college paper, the most useful comments address argument and use of sources, not comma placement. Pick two or three priorities and leave the rest. Students revise better when they are not overwhelmed.

End with a note that names the single biggest step toward a stronger next paper. It gives students something concrete to carry into the next assignment. Many students say this closing note is the only comment they truly read.

Use Technology to Extend Instructor Time

AI grading tools can produce first-pass feedback against an instructor's own rubric, which is then reviewed and adjusted. GraideMind is built for this sort of workflow. Instructors and TAs spend their time on judgment and personal notes rather than repeating the same comments.

Policies matter here. Be transparent with students about how feedback is generated and reviewed, and follow your institution's guidelines on technology in assessment. Clear communication builds trust and avoids confusion later.

Encourage Independent Argument

Christie's novel is well known, so students will find plenty of online summaries and analysis. Design prompts that require an original position, and grade for the quality of the argument's development. A specific, debatable question is your best defense against generic papers.

Add a short reflection or planning step to the assignment. It gives you more insight into each student's process and encourages ownership. It also makes the final paper easier to evaluate.
