Source evaluation essays ask students to judge whether a news story deserves their trust, and the quality of the judgment depends heavily on the feedback they receive. Generic comments such as "consider the credibility of this source" tell students nothing about how to do that. In a unit shaped by The Influencing Machine, where the book shows how reporting has been shaped by commerce, technology, and politics, feedback needs to be much more specific.

The most helpful comments identify exactly which part of the evaluation is missing. A student might check whether a source has an author byline but never ask who funds the outlet, or might trust a story because it cites an expert without checking whether that expert has relevant credentials. Pointing to the gap, rather than simply saying the evaluation is shallow, gives the student a clear next step.

It also helps to separate comments about the evaluation process from comments about the writing. A student can run a sophisticated analysis and present it poorly, or write smoothly about a superficial judgment. Marking those two dimensions separately prevents your feedback from blending into a single vague impression and makes your scoring more defensible.

Comments that prompt better questions

Questions in the margin often work better than corrections because they model the thinking you want. Asking who benefits if readers believe this framing teaches students to look at incentives. Asking what the story leaves out invites them to think about omission, which is one of the most common ways that coverage shapes perception without containing a single false statement.

• Who produced this story, and what do they gain if readers trust it?
• What kinds of sources does the story rely on, and whose voices are missing?
• Does the headline match what the body of the article actually shows?
• Can the main claim be checked against a second, independent report?
• What would a reader with the opposite assumption notice that you did not?

Balancing praise and challenge

Feedback that only points out weaknesses can discourage students who are already unsure about their judgment. Beginning with one specific strength, such as a sharp observation about word choice in a headline, shows that you read carefully. It also tells the student which skills to keep using while they work on the areas you flagged.

Challenge matters just as much, particularly for strong students who tend to plateau when comments are all positive. A short note asking a confident writer to consider whether their trusted source might also have blind spots can produce the most growth of any comment in the paper. Calibrating the level of challenge to each writer is where teacher judgment is hardest to replace.

Building a comment bank you can reuse

Teachers who grade source evaluation essays every term tend to write the same dozen comments repeatedly. Collecting them into a bank organized by rubric criterion saves time and improves consistency, since the wording has already been refined through use. Each comment should still be adapted with a reference to the student's own example so it does not read as boilerplate.

AI feedback tools can speed this up by suggesting comments aligned to your rubric and drawing on the actual text of each essay. The teacher then reviews, trims, and personalizes them. Used this way, the technology handles the mechanical work of finding where a comment applies, while the teacher decides whether the comment is accurate and kind.

Closing the loop with a revision

Comments only pay off when students act on them, so build in a short revision step for at least one source evaluation essay per unit. Ask students to highlight the sentence they changed in response to your feedback and explain why. That small reflection reveals whether the comment was understood, and it often exposes confusion that you can address with the whole class.

Over time, students begin to anticipate the questions you ask and answer them in their first drafts. That shift is the clearest sign that feedback is working, because it means the habits behind the comments have become part of the student's own process. At that point, you can reduce the volume of margin notes and focus on the highest-value issues.
