After grading enough essays on "Second Variety," patterns begin to repeat. Students love the twist, in which the machines turn out to resemble humans, and many essays spend most of their length retelling it. Others offer sweeping claims about war or technology without grounding them in the story. Recognizing these patterns lets you respond efficiently and design instruction that prevents them.

The most common mistake is summary in place of analysis. A student recounts how Hendricks travels to meet the enemy and discovers the truth about the claws, but never explains what the sequence suggests. The fix is to ask what the events reveal about trust, fear, or the nature of enemies. A single question like this can redirect a whole paragraph.

Another frequent problem is the unsupported generalization. Statements such as "war makes people paranoid" may be true, but they need to be connected to specific moments in the story. Ask the student which scene shows paranoia most clearly and what details make it convincing. This teaches them to treat the text as the source of their claims.

Mistakes in Structure and Reasoning

Structural problems also appear often. Some essays present each paragraph as a separate observation with no connection to a central argument. Others bury the thesis in the final paragraph, so the reader is left guessing until the end. Teaching students to state a clear claim early and to link every paragraph back to it can greatly improve coherence.

• Summarizing the plot instead of analyzing its meaning
• Making sweeping claims about war or technology without evidence
• Using quotations without explaining their significance
• Presenting paragraphs that do not connect to a central thesis
• Ignoring the story's ending when discussing its message

Fixes You Can Teach Directly

Many of these problems can be addressed with short, targeted exercises. To fight summary, have students rewrite a summary sentence as an interpretive sentence, adding a phrase that explains what the event means. To address unsupported claims, ask them to attach a specific example to every general statement. Practicing these moves in small doses is more effective than lecturing about them.

Use real examples, with names removed, to show the difference between a weak and a strong paragraph. Students can compare them and describe what makes the stronger one work. This builds their ability to evaluate writing, which in turn improves their own. It also makes the abstract language of the rubric more concrete.

Using Patterns to Plan Instruction

As you grade, keep a tally of the issues you see. If most students struggle with the same thing, address it with the whole class before the next assignment. If only a few have a problem, handle it individually. This keeps your instruction responsive and prevents you from reteaching what students already know.

Share the tally with students in general terms so they know what to watch for in their own writing. A short list of the three most common problems, along with quick strategies for fixing them, can serve as a checklist for revision. Students often find it reassuring to learn that their mistakes are common. That awareness makes them more willing to revise.
