The Handwritten Letter and the Octopus Cartoon
An 11th grade U.S. History class of 30 students is in the fourth week of a Progressive Era unit. The teacher has planned a 45-minute document analysis lesson around two sources: a 1904 magazine cartoon showing a giant octopus labeled "The Trusts" wrapping its tentacles around a factory, a farm, and a railroad; and a 1904 letter from a textile mill owner to his state senator arguing that a proposed child-labor law would "ruin honest families." Students work in groups of four for 20 minutes on the question "Did most Americans support federal regulation of business in 1904?" In the final 12 minutes the teacher circulates and hears three groups say the letter is "more reliable" because it is handwritten, signed, and addressed to a public official, while the cartoon is "just a drawing." One student adds that both sources are biased, so the question cannot really be answered.
1. Identify the two sourcing prompts you would pose to move groups past the reliability ranking, and explain why each prompt does the work you need.

Prompt 1: "Who created this, for what audience, and what did the creator want that audience to think or do?" This redirects attention from authenticity to purpose. The cartoon was made for a mass magazine audience and argues visually that monopolies reach into every sector; the letter was written by one mill owner to one legislator and argues that regulation threatens family wage earners. Prompt 2: "What can this source tell us that the other cannot?" This forces corroboration rather than a winner-take-all reliability contest. The cartoon is evidence of a public argument circulating widely; the letter is evidence of organized elite opposition and of the specific语言 employers used. Together they support a claim about contested public opinion, not a headcount. Ranking sources by handwriting style is a category error: neatness and signatures speak to provenance, not to representativeness. The prompts convert "Is it biased?" into "What is it evidence of?"
2. How would you respond to the student who says both sources are biased so the question cannot be answered?

I would agree with the observation and then change its implication. Yes, both are biased, because both were made by people with purposes; that is exactly why they are useful. Bias is data about position and argument, not a disqualification. I would model one sentence: "The cartoon tells me that critics of trusts wanted ordinary readers to see monopolies as a nationwide threat, while the letter tells me that at least some employers organized against child-labor laws." Then I would ask what third source would help test the claim about most Americans, such as a sample of newspaper editorials or election results. The reasoning move is from "biased therefore unusable" to "perspectival therefore usable for a specific question," which is the sourcing skill the lesson is actually teaching.
3. Design a two-minute exit ticket that would show whether students can use both documents as evidence rather than rank them.

I would use one sentence frame: "Using both documents, one thing I can conclude about public opinion on regulating business in 1904 is ______, because the cartoon shows ______ and the letter shows ______." This requires synthesis instead of recall. A strong response names a contested climate and cites each source for a different claim, for example that regulation had vocal mass support and vocal elite opposition. A weak response says the letter is more trustworthy or repeats cartoon content only. I would sort the tickets into three piles the next day: synthesis, one-source use, and reliability ranking. The piles determine whether the next lesson is a full corroboration activity or a five-minute reteach, so the exit ticket changes instruction rather than merely documenting it.
