The districts participating in A Nation Among Nations cover an area of 450 square miles; 70 percent of students come from military families, nearly half of the students come from families living in poverty, and diversity is on the rise. Each year teachers will participate in two 8-week instructional modules taught by university professors and three inquiry-based instructional workshops delivered by DBQ. The 10-day summer field studies will involve excursions to historic sites, and, during a 1-week summer curriculum workshop, teachers will learn about incorporating multimedia tools and resources into the curriculum. Each year, at least 75 teachers will study the decisions and actions made by individuals whose choices changed the outcome of history; teachers who complete the activities will receive 6 hours of university credit for their work. Teachers and, consequently, their students will learn to read and think like historians—to investigate historical questions, frame historical arguments and evaluate primary source documents. The major instructional strategy will be document-based questions. Special emphasis will be given to content that reinforces significant themes of American history, that makes history relevant by supplementing historical themes with primary sources and experiential field work, and that reveals primary sources that are not widely available. Teachers will develop, implement and disseminate curricula based on project activities.
