Sourcing a 1936 Photograph Without Killing the Evidence
Mr. Delgado's fifth graders are analyzing a 1936 Farm Security Administration photograph of a migrant mother and three children. In small groups, students list what they see and then write a caption. Of 24 exit tickets, 19 describe the family as 'sad' or 'desperate' and conclude that 'this is what the Great Depression was like for everyone.' Only 3 mention who took the photograph or why it might have been taken. Mr. Delgado has one 45-minute period before the unit assessment, which asks students to explain how New Deal programs affected different groups of Americans. He wants students to keep using the photograph as evidence without treating it as a neutral window onto the past. Available to him: the original caption and date, the photographer's field notes, and a 1939 letter from a Dust Bowl family that stayed in Oklahoma and eventually bought a small farm.
1. Diagnose the misconception in the exit tickets and explain why the planned 45-minute response should not be more 'what do you see' practice.

This is not primarily a comprehension failure. Students have read the image's emotional content accurately and then used that content as a claim about an entire decade. They are treating a photograph as a transparent record rather than as a constructed source with a maker, a purpose, and an audience. The fact that only 3 of 24 mention the photographer is the tell: sourcing is available to them but not habitual.
That diagnosis matters for the response. If the problem is that the image is being treated as a window, then more observation practice deepens the error, because observation is exactly the move they have already over-learned. The lesson should instead put pressure on three questions: who made this, when, and for what purpose; what is inside the frame and what is necessarily outside it; and what other evidence would confirm or complicate the caption.
There is a real risk in overcorrecting - students who conclude that photographs are 'biased' and therefore useless. The goal is disciplined use of evidence, not dismissal: this photograph is excellent evidence of what the photographer chose to show and of how a federal agency wanted poverty portrayed in 1936. Shifting the evidentiary claim, rather than rejecting the source, is the instructional target.
2. Outline the 45-minute sequence using the caption, field notes, and the 1939 letter, and identify the specific judgment students should be able to make by the end.

Minutes 1–8: reveal the caption and date. Students answer in writing, individually: who made this, when, and who paid for it. Brief share-out establishes that a government agency hired the photographer, which does not make the image false but does make it purposive.
Minutes 8–20: field notes. Students compare the photographer's notes to what they inferred from the image, listing one place the notes match their inference and one place the notes add something they could not see. This teaches that the image is a selection: the notes contain context the frame excludes.
Minutes 20–35: the 1939 letter. In pairs, students write two claims the photograph supports and one claim it cannot support alone, then revise the original caption so it is defensible. The letter does not overturn the photograph; it widens the sample, showing a family who stayed, which challenges 'for everyone.'
Minutes 35–45: whole-class chart with three columns - what the photo shows, what it can be used to prove, what it cannot. The exit ticket should ask for one sentence of the form 'This photograph is evidence that ___, but it does not show ___.'
The judgment students should reach is not that the image is untrustworthy but that its evidentiary weight is narrower than their first caption assumed.
3. The unit assessment asks how New Deal programs affected different groups. Critique a proposed assessment item that says 'Use the photograph to describe the experience of Americans during the Great Depression,' and propose a better item.

The proposed item is misaligned in exactly the way the lesson tried to correct. It asks students to generalize from a single purposive source to a national experience, which rewards the original misconception. A student who writes 'Americans were desperate' would score well, and a student who writes 'this shows how one agency chose to represent migrant poverty in 1936' would look evasive. The item also gives no opportunity to use the letter or the field notes, so the comparison work of the lesson is not assessed at all.
A better item keeps the source but changes the verb and adds a second source. For example: 'Using the photograph and the 1939 letter, explain one way New Deal programs affected migrant families. In your answer, identify one thing the photograph shows clearly and one thing it cannot tell you without the letter.' That item requires contextualization, evidence selection, and recognition of limits - the three moves the lesson taught.
A scoring guide should make the reasoning visible: credit is given for naming the source's origin or purpose, for using specific details from both documents, and for stating a limit on the photograph's testimony; a response that asserts a national mood from the image alone should not earn full credit even if the writing is strong. If the item cannot be rewritten before the assessment, the photograph should be paired in the prompt with the letter so that generalization is at least anchored in more than one source.
