Open a stack of student DBQ essays and you'll find a common pattern: each paragraph introduces a document, summarizes its content, and moves to the next. The result reads like a encyclopedia entry, not an argument. The student has collected information without analyzing it or using it to support a claim.

Summary Thinking vs. Argument Thinking

Summary thinking asks: What does this document say? Argument thinking asks: Why does this matter to my claim? How does this source support my thesis? These are fundamentally different intellectual moves. Summary is often the first step, but it's not historical argument.

A student writing summatively might say: 'Document A is a letter from a farmer who complains about taxes.' A student thinking argumentatively might say: 'The farmer's complaint about taxes—expressed in deeply personal language about the hardship his family faces—reveals how abstract economic policy translated into concrete suffering for ordinary colonists, helping explain why economic resentment fueled revolutionary commitment.'

• Summary reports information from sources. Argument uses sources to develop understanding.
• Summary organizes around documents. Argument organizes around ideas.
• Summary answers 'What happened?' Argument answers 'Why does this matter?' or 'What does this show us?'
• Summary can stand alone. Argument requires a thesis to unite it.

Teaching the Argument-Centered Approach

Have students develop their thesis before reading documents. This ensures they're organizing around an idea, not around sources. Then, have them choose which documents support their thesis best and explain why those sources matter to their argument.

Use revision prompts that push toward argument: 'You've explained what this document says. Now explain why it matters to your thesis.' 'This paragraph summarizes multiple sources. What insight do they together support? Make that explicit.' These questions guide students toward genuine argumentation.

Once students understand the difference, their DBQ essays shift fundamentally. They stop collecting documents and start using them. That shift marks real historical thinking.
