Training Data and Model Evaluation
Understanding the importance of data quality, feature engineering, and metrics for model performance.
Key Questions
- Explain the critical role of training data in machine learning model development.
- Analyze various metrics used to evaluate the performance of AI models (e.g., accuracy, precision, recall).
- Critique the potential pitfalls of overfitting and underfitting in model training.

About This Topic
The Roaring Twenties: Culture Wars covers the intense social and cultural tensions that defined the decade. This topic examines the conflict between the 'modern' urban culture of flappers and jazz and the 'traditional' rural values focused on religion and prohibition. Students analyze the Scopes 'Monkey' Trial, the failure of Prohibition, and the resurgence of the KKK as examples of this deep national divide.
For 11th graders, this topic is essential for understanding how rapid social change can trigger a powerful backlash. It highlights the role of the media in nationalizing these cultural conflicts. Students grasp these complex social dynamics faster through mock trials of the Scopes case and collaborative investigations into the 'two Americas' of the 1920s.
Active Learning Ideas
Mock Trial: The Scopes 'Monkey' Trial
Students take on the roles of William Jennings Bryan, Clarence Darrow, and the judge. They argue the case for and against teaching evolution, focusing on the deeper conflict between religious tradition and modern science.
Inquiry Circle: The Failure of Prohibition
Small groups research the rise of bootlegging, speakeasies, and organized crime. They must explain why the 'Noble Experiment' failed to achieve its goals and how it actually led to a decrease in respect for the law.
Think-Pair-Share: The New KKK
Students read about the resurgence of the KKK in the 1920s. They work in pairs to discuss how it differed from the Reconstruction-era KKK by targeting immigrants, Catholics, and Jews in addition to Black people.
Watch Out for These Misconceptions
Common MisconceptionThe 1920s was a time of prosperity for everyone.
What to Teach Instead
While cities boomed, the agricultural sector was in a deep depression throughout the decade. A 'rural vs. urban' wealth comparison helps students see the uneven nature of the 1920s economy.
Common MisconceptionProhibition meant that people stopped drinking.
What to Teach Instead
Alcohol consumption actually continued in many ways, and the law created a massive new market for organized crime. Peer-led analysis of crime statistics from the era helps students see the unintended consequences of the 18th Amendment.
