Fundamentals of Machine Learning: Unsupervised Learning
Students explore unsupervised learning techniques like clustering and dimensionality reduction to find hidden structures in unlabeled data.
Key Questions
- Explain how unsupervised learning can discover patterns without explicit labels.
- Compare the applications of clustering and dimensionality reduction in data analysis.
- Analyze the challenges of evaluating the performance of unsupervised learning models.

About This Topic
This topic examines the legal and grassroots strategies of the Civil Rights Movement, focusing on the shift from litigation (Brown v. Board) to direct action (Montgomery Bus Boycott). Students analyze how the movement pressured the federal government to pass the Civil Rights Act of 1964 and the Voting Rights Act of 1965, effectively ending de jure segregation and protecting the franchise.
For seniors, this is a study in how 'we the people' can force the government to live up to its founding ideals. It connects to ongoing discussions about voting access and systemic inequality. This topic comes alive when students can physically model the patterns of social change by analyzing the 'Letter from Birmingham Jail' and the strategic choices made by movement leaders.
Active Learning Ideas
Inquiry Circle: Strategy Analysis
Divide the class into 'Litigation' (NAACP) and 'Direct Action' (SCLC/SNCC). Students research a specific event and present how their assigned strategy contributed to a specific legislative or legal victory.
Think-Pair-Share: The Letter from Birmingham Jail
Students read excerpts of MLK's letter. They must identify his four steps of a nonviolent campaign and discuss why he argued that 'justice too long delayed is justice denied' in response to white moderates.
Gallery Walk: The Impact of the 1964 Act
Display the different 'Titles' of the Civil Rights Act (e.g., Title II: Public Accommodations, Title VII: Employment). Students rotate and find modern examples of how these laws still protect people today.
Watch Out for These Misconceptions
Common MisconceptionThe Civil Rights Movement ended racism in America.
What to Teach Instead
The movement ended *de jure* (legal) segregation, but *de facto* (social/economic) segregation persisted. Peer discussion about 'The Great Migration' and 'Redlining' helps students see the difference between changing laws and changing outcomes.
Common MisconceptionThe movement was entirely non-violent and unified.
What to Teach Instead
There were deep internal debates about tactics (e.g., Black Power vs. Non-violence). Peer-led 'Debate Reenactments' between different movement factions help students appreciate the complexity of social change.
