Allen's account of the big bull market and the crash of 1929 is among the most memorable parts of Only Yesterday, full of ordinary people buying stocks on margin and brokers' offices crowded with hopeful customers. Student essays on the topic frequently reduce the whole episode to a single cause, such as greed or speculation. Grading these essays requires a rubric that rewards economic reasoning rather than moral judgment. The best papers explain how the boom worked before explaining how it ended.

A common weakness is vague explanation of buying on margin. Students write that people borrowed money to buy stock, but they do not explain why that made the market fragile when prices began to fall. A strong essay describes how falling prices triggered demands for more cash, which forced sales, which pushed prices down further. Reward students who can walk a reader through that chain in plain language.

Another frequent issue is treating the crash as the cause of the Great Depression. Allen's book ends before the full story of the Depression unfolds, and a careful student recognizes that the crash was one event in a larger collapse. Essays that claim the crash alone caused the Depression oversimplify. Feedback can ask what other weaknesses in the economy the student could investigate.

Assessing Economic Explanation

Students do not need advanced economics to write well about the crash, but they do need to explain mechanisms clearly. A paragraph on installment buying, rising stock prices, and consumer confidence should show how each piece connects to the others. When grading, ask whether a classmate who had not read Allen could follow the explanation. If the answer is no, the paper needs more clarity rather than more facts.

• Explains buying on margin and why it increased risk
• Connects the boom to broader optimism about prosperity
• Distinguishes the October 1929 crash from the later Depression
• Uses specific events and figures from the period
• Considers more than one cause and weighs their importance

Evidence and Numbers in Student Writing

Numbers can strengthen an economic essay, but only when students explain what they mean. A figure about the rise in stock prices means little unless the student connects it to the growing number of investors or the level of borrowing. Teach students to introduce a statistic, interpret it, and tie it to the claim. Graders should reward that three step pattern and flag figures that appear without context.

It is also worth checking accuracy, since details about dates and amounts are easy to misremember. A short fact check on key claims helps maintain the integrity of the grade. Students can be asked to cite the chapter or source for each major figure. This habit improves both accuracy and the credibility of their writing.

Providing Feedback on Complexity

The strongest essays acknowledge that historians still debate the causes of the crash and the Depression. A student who recognizes this uncertainty and explains why a single answer is hard to defend shows real sophistication. Feedback should encourage this humility without letting students retreat into vagueness. The goal is a clear claim that admits its limits.

Because essays on this topic can be long and technical, grader fatigue is a risk. Rubric based comment drafting, whether manual or assisted by software, helps maintain consistent standards across a large stack. Teachers can then devote their attention to the points that require judgment, such as whether an explanation is actually correct. Consistency and accuracy together make the grade trustworthy.

Connecting the Unit to the Rest of the Course

The crash essay is a natural bridge between the 1920s and the Depression, so use it to set up the next unit. Ask students to identify questions the essay raises but cannot answer. Those questions become a starting point for further study. It also reinforces the idea that history is an ongoing inquiry rather than a set of settled stories.

Looking back at the rubric scores across the class will show whether students understood the mechanisms or only the narrative. If many struggled with economic explanation, consider adding a short activity before the next unit that practices describing cause and effect in plain language. Small adjustments of this kind make future essays stronger. Allen's vivid account then becomes a foundation for sharper analysis.
