After watching

For “Evaluate Explanations of the Great Migration,” what idea from the video helps with the lesson task, and what must still be checked in the supplied text, data or model?

An external player loads only after you choose Preview or Show to class. Playback connects to YouTube. Videos belong to their creators; availability and embedding can change.

Learning objective

Compare explanations for migration, identify their evidentiary limits and write a qualified multi-causal account.

Before you begin

  • Distinguish aggregate patterns from individual motives and evaluate competing explanations.

Gather your materials

  • Paper or a note-taking document
  • Pencil; the original lesson texts and records below

Language to know

Migration
Movement of people from one place to another.
Push factor
A condition contributing to a decision to leave.
Pull factor
A condition contributing to attraction toward a destination.

Understand the concept

The National Archives describes the Great Migration as the movement of approximately six million Black Americans from the South to Northern, Midwestern and Western states roughly during the 1910 s–1970 s. Its overview identifies racial violence and Jim Crow oppression as well as economic and educational opportunities. Original fictional letter for comparison, not an archival quotation: “I left after threats in our town; my cousin’s report of factory work helped me choose the destination.” The letter illustrates how leaving and destination decisions may involve different causes. It cannot stand as a representative account of millions.

Teach it step by step

  1. Separate the official aggregate overview from the invented individual illustration.
  2. Evaluate the classroom explanation “Everyone moved only for higher wages.”
  3. Distinguish reasons for leaving from reasons for choosing a particular destination, allowing interaction.
  4. Write a qualified account and identify what evidence could test variation across periods or communities.

Make the thinking visible

Worked example or model response

“Economic opportunity mattered in the overview, but a wages-only explanation excludes violence, oppression and education. The fictional letter shows a possible interaction between safety and a family network; it illustrates a mechanism, not its frequency. Actual comparisons require dated individual and aggregate records.”

Guided practice

Together explain why finding one authentic wage-focused letter would not establish a universal motive.

Independent practice

Write 160 words comparing the wages-only claim with the overview and model. Acknowledge uncertainty about relative importance and propose a source plan for one defined city or period.

Quick assessment

Can an aggregate count explain the exact motive of a particular migrant?

Answer key & assessment criteria

Answers and teaching guidance

  1. Guided: One letter documents one account; even a genuine source cannot by itself support a claim about everyone.
  2. Independent criteria: Account preserves the overview’s range of factors, labels the letter fictional, distinguishes scale and proposes evidence appropriate to a limited comparison.
  3. Quick check: No. A count describes scale and pattern; individual motives require additional records interpreted in context.

Look for: Account preserves the overview’s range of factors, labels the letter fictional, distinguishes scale and proposes evidence appropriate to a limited comparison. Accept a different conclusion when it addresses the task and is supported by the supplied material.

Make it work for your learner

More support

Use leaving/destination/scale columns and read the fictional letter separately from the historical note.

Extension challenge

Compare two hypothetical source collections with different selection methods and explain how each might overrepresent a particular explanation.
