Synthesis essays ask students to build their own argument by drawing on several sources, and a unit centered on Hunger of Memory offers rich material for them. Teachers commonly pair excerpts from the memoir with essays by Amy Tan, Gloria Anzaldúa, or James Baldwin on language, so that students can explore how different writers think about the connection between speech and identity. The grading challenge is separating the student's own argument from the sources they use.

The defining feature of synthesis is that the student's claim is not found in any single source. A student who writes that Rodriguez believes public language is necessary and Tan believes home language is valuable has summarized two positions but has not synthesized them. A student who argues that both authors reveal that language choices are shaped by audience has made a claim that depends on bringing the sources together.

Because of this, the rubric for synthesis should place the greatest weight on the thesis and the integration of sources. It should also include a criterion for source use that distinguishes between sources that are merely mentioned and sources that are put into conversation with each other.

Rubric Criteria for Synthesis

A good synthesis rubric describes what each score level looks like in terms of the student's relationship to the sources. At the top level, the student controls the conversation and uses sources to support an original position. At the lower levels, the sources control the essay, and the student acts mostly as a reporter of what each author says.

• Thesis: presents an original position that depends on more than one source
• Source integration: places sources in conversation, noting agreement, tension, or qualification
• Evidence: uses accurate, specific references and avoids overquoting
• Organization: structures paragraphs around the student's ideas rather than around each source
• Attribution: identifies sources clearly and uses the required citation format

Detecting Summary Disguised as Synthesis

The most common error is summary dressed up with transitions. Phrases such as "On the other hand" and "Similarly" give an essay the look of synthesis while the paragraphs still treat each source in isolation. To check, look for sentences where two authors appear together, and ask whether the student explains why their relationship matters.

Feedback for this problem should be concrete. A comment that asks the student to name the shared question both authors are answering, and then to state where they diverge, usually moves the draft toward real synthesis. Without that kind of prompt, students often keep adding sources instead of improving the connection between the ones they have.

Grading at Scale

Synthesis essays are long and source-heavy, which makes them among the most time-intensive to grade. You need to recall each source, check the accuracy of each reference, and evaluate the connections between them. In a department that gives the same synthesis assignment across several sections, shared scoring guides and calibration sessions help keep scores consistent.

AI-assisted tools can support calibration by applying the same rubric to every essay and surfacing places where scoring differs from teacher to teacher. That makes it easier to have productive conversations about borderline papers during department meetings.
