DOC C

The Post-War Agricultural Trap

Fact: Farm Depression started in 1920

During World War I, American farmers heavily expanded fields to feed allied nations. Post-war, European farms recovered. Crop prices collapsed under oversupply. Farmers were unable to sell for a profit and faced foreclosures long before 1929.

Document Analysis Questions

1. Based on Doc A, explain how the gap between manufacturing output and worker wages created a major structural problem.

2. According to Doc B, how did installment plans mask the reality of stagnant worker wages?

3. Why were American farmers (Doc C) experiencing an economic depression a decade before the stock market crashed?

Guided Note-Taking & Inquiry Page 3 of 3

_______ %

• This worked as long as stocks went up, but a dip triggered _________________ calls, forcing investors to dump shares and creating a massive selling panic.

SLIDE 7

Confidential Teacher Guide Investigation Answers & Rubrics

Part II: Document DBQ Answer Rubric (Page 2 Questions)

Question 1 (Doc A - Wage Gap): Ideal responses must identify that while factory efficiency increased drastically (+32%), wage growth (+8%) stayed stagnant. This meant workers had no purchasing power to buy the products, causing inventory buildup and mass factory layoffs.

Question 2 (Doc B - Installment Plans): Students should describe how credit acts as an economic delay-timer. It let families ignore flat salaries temporarily until the debt bubble broke, resulting in immediate personal bankruptcies.

Question 3 (Doc C - Rural Depression): Responses must outline that post-WWI mechanized crop expansion and recovered global competition crashed wheat prices, destroying family farms. This means 25% of the country was in poverty *before* the stock market crash.

Part III: Synthesis Essay Grading Framework

Scale of 1-4 Points based on standard AP/US History DBQ rubric standards:

4 Points: Mastered Asserts clear thesis. Uses 2+ Document references (Doc A-C). Accurately relates credit overextension or agricultural decline directly to 1930s systemic crash.

3 Points: Proficient Presents thesis and references documents. Explains the connection between 1920s structures and the Depression, with minor gaps in causation.

2 Points: Developing States a simple opinion but relies on vague general statements. Limited direct citations or poor reasoning between credit traps and the crash.

1 Point: Incomplete Incomplete attempt. Simply repeats document text without formulating any causal argument or historical reasoning.

Classroom Facilitation Tips

• Hook Facilitation: When students do the "Millionaire Mirage" simulation, poll the class to see how many bought "luxury mansions" or "speculated further". Use their initial shock when the bank closes to introduce the fragility of fractional reserve banking.

• Formative Checkpoint: Walk around during Slide 5 of the lecture to ensure students grasp that 1920s farmers experienced a "silent depression" first. This prevents the common misconception that the stock crash alone caused the Great Depression.
