Teacher's field guide

What This Standard Means

What Students Need to Do: Students explain how U.S. policy changed from warning European powers to claiming a right to intervene. They evaluate U.S. actions in Panama and other Latin American nations using evidence from multiple viewpoints.
What Mastery Looks Like: Students can distinguish the Monroe Doctrine from the Roosevelt Corollary. They can use evidence about the Panama Canal or another intervention to explain U.S. goals and Latin American resentment.
Common Misconceptions: Students may treat both policies as identical or assume all Latin American leaders welcomed U.S. involvement. They may also believe Panama freely gave the Canal Zone to the United States without pressure or conflict.
How to Assess It: Ask students to explain one U.S. action under the policy and one effect on relations with Latin America. Require two specific historical details.
