✍️ DBQ / LEQ / SAQ Writing Shortcuts
| Component | Quick Tip |
|---|---|
| Thesis (all 3) | One defensible claim + line of reasoning. Must go beyond restating the prompt. "Although X, ultimately Y because [reason 1], [reason 2], and [reason 3]." Put it in the intro AND restate in conclusion. |
| Contextualization | Broader historical context from a DIFFERENT time period or place that connects to your argument. Must be a full paragraph (not just a sentence). "In the decades before the Civil War..." or "The legacy of Reconstruction shaped..." |
| DBQ: Use the docs | Cite docs by number [Doc 1] or by author/title. Must use at least 3 docs for any credit; at least 6 for evidence points. Use docs to support your argument — don't just summarize them. |
| HAPP analysis (DBQ) | For each document: identify Historical Context, Audience, Purpose, or Point of View — AND explain how it affects the document's argument or reliability. "The author's position as a factory owner (POV) means he likely downplays labor conditions." |
| Outside evidence (DBQ) | Include specific historical evidence NOT from the provided documents. One solid outside example with an explanation earns this point. |
| Complexity | Qualify, corroborate across time/geography, or explain cause and effect. "While economic factors drove expansion, ideological arguments like Manifest Destiny legitimized what was fundamentally economic..." One complexity example with explanation earns the point. |
