As a high school social studies teacher, the author provides his students with a curriculum that helps them think about immigration issues. He describes the instructional units that he has developed to address two key questions about U.S.-Mexican immigration: What is the origin of the U.S.-Mexico border? and Why are so many people today fleeing Mexico and coming to the United States? Because the traditional social studies curriculum in U.S. schools does not give accurate or detailed answers to these questions, the author believes that "we can't simply abandon young people to the stereotypes, biases, and historical misinformation that have become so much a part of the public discourse around immigration."
