Why did the United States enter World War II?
Several different approaches should be implemented while examining the U.S. role in World War II and the American home front. These teaching approaches should include (as appropriate) lectures, individual and group readings, cooperative group work, applicable audio and visual materials as well as pertinent technology resources. Students should occasionally be asked to put themselves in the place of those who experienced life during World War II and to draw connections between events and attitudes of then and now in order to encourage critical thinking and reasoning skills.
