After grading essays on The Big Wave across multiple classes and school years, most teachers begin to notice a recurring set of mistakes that show up far more often than any others, and recognizing these patterns in advance can make grading considerably faster and feedback considerably more targeted. Because this novella is relatively short and frequently assigned, these common mistakes are well documented enough that new teachers can benefit from a heads-up before they encounter their first stack of essays on this particular text. Understanding not just what these mistakes are but why they happen, and what specific feedback most effectively addresses each one, turns grading from a purely reactive process into one where a teacher can anticipate and efficiently address the most likely issues in any given batch of essays.

The single most common mistake is plot summary disguised as analysis, where a student essay accurately recounts the sequence of events, the eruption, the wave, Jiya's rescue, and his eventual recovery, without ever actually making an interpretive claim about what those events mean or reveal about a larger theme. This mistake typically stems from students not yet having a clear enough distinction in their minds between describing what happens and explaining why it matters, which is a foundational analytical skill still developing throughout middle school. The most effective feedback for this mistake asks a direct, pointed question, such as asking the student what this event shows about the character or theme they are discussing, rather than simply noting that the paragraph is too summary-heavy, since the question format pushes students toward the actual interpretive move they need to make in revision.

A second extremely common mistake is confusing Kino and Jiya's perspectives or experiences, particularly in essays discussing fear or grief, since both boys are present through much of the story and their emotional arcs can genuinely blur together in a student's memory, especially for students who read the text somewhat quickly or a while before writing the essay. This mistake often produces essays that attribute Jiya's direct experience of loss to Kino, or vice versa, undermining the essay's central argument even when the underlying interpretive idea might otherwise be reasonably sound. Catching this specific error requires careful, attentive reading on the teacher's part, since the mistake can be easy to miss if a grader is reading quickly for overall argument quality rather than checking factual accuracy of character attribution sentence by sentence.

Structural and Organizational Mistakes Worth Flagging Early

A common structural mistake involves essays that state a clear thesis in the introduction but then drift into a different, related but distinct argument by the final body paragraph, often because the student discovered a more interesting idea partway through drafting but did not go back to revise the original thesis to match. This mistake is worth catching specifically because it often indicates genuine, developing thinking on the student's part, meaning the feedback should acknowledge the interesting idea that emerged while still explaining clearly that the thesis needs to be revised to match where the essay actually ends up. Treating this mistake as evidence of a student actively thinking through the material, rather than simply as a structural error, tends to produce feedback that encourages rather than discourages this kind of exploratory drafting process.

• Plot summary disguised as analysis: events described without any interpretive claim about meaning
• Confusing Kino and Jiya: attributing one character's experience or emotion to the other
• Thesis drift: the essay's actual argument shifts from what the introduction originally claimed
• Single-source evidence: the entire essay relies on just one scene, usually the old gentleman's dialogue
• Unexplained quotations: textual evidence is included but never actually explained or connected

Evidence-Related Mistakes That Slow Down Grading

Another frequent mistake is relying almost entirely on a single scene, most often the old gentleman's dialogue about mountain and sea life, as the sole piece of evidence throughout an entire essay, even when the assignment or the student's own thesis would genuinely benefit from drawing on multiple different moments in the story. This pattern often occurs because the old gentleman's dialogue is the most quotable, thematically explicit passage in the novella, making it an easy and tempting default for students who have not yet developed the habit of searching more broadly across the text for supporting evidence. Feedback addressing this mistake should point students toward at least one or two specific alternative scenes that would also support their argument, since simply telling a student to use more evidence without pointing toward specific alternatives often leaves them unsure where else in the text to look.

A related mistake involves including a relevant quotation but never actually explaining its connection to the essay's argument, leaving the quotation to function almost as decoration rather than as genuine support for a claim. This mistake is sometimes harder to catch quickly during grading than the previous ones, since the quotation itself is often perfectly well chosen and relevant, and the gap only becomes apparent when a grader specifically checks whether the sentence following the quotation actually explains its significance rather than simply moving on to a new point. Teaching students the specific habit of always including an explanation sentence immediately after any quotation, as a simple, consistent structural rule, tends to significantly reduce how often this particular mistake appears in future essays.

Using Pattern Recognition to Speed Up Grading and Feedback

Once a teacher has graded this assignment enough times to recognize these common patterns, grading itself becomes noticeably faster, since the teacher can quickly scan for these specific, well-known issues rather than approaching each essay as an entirely unknown quantity requiring extensive discovery of what might be wrong. Building a personal or department-shared bank of prepared feedback language for each of these common mistakes, ready to be quickly adapted to the specific details of an individual essay, can further speed up the writing of feedback comments without sacrificing their specificity or usefulness to the student receiving them. This kind of pattern-based efficiency is one of the genuine advantages experienced teachers of this text develop over time, and it is worth deliberately building rather than leaving to accumulate only through years of incidental experience.

AI-assisted grading tools are particularly well suited to catching several of these specific, well-documented common mistakes quickly and consistently, such as flagging quotations that appear without a following explanation sentence, or identifying essays where the concluding paragraph's argument does not clearly match the thesis stated in the introduction. Because these mistakes are so well known and predictable for this particular text, a tool calibrated to watch for them specifically can provide genuinely useful first-pass feedback, flagging exactly the issues a teacher would otherwise need to hunt for manually across a full stack of essays. This targeted, pattern-aware use of grading technology, built around the actual documented common mistakes for a specific, frequently assigned text, represents one of the more practical and immediately useful applications of AI-assisted grading in a literature classroom.
