In this lesson, students, working in groups, will be analyzing primary source documents that highlight the problems that arose in the United States at the turn of the twentieth century. There are 11 major documents within this lesson that delve into the major muckrakers who spoke of the conditions within the nation. These descriptions not only informed the public, but also urged politicians, especially the U.S. Presidents, beginning with Theodore Roosevelt, to take action to improve the conditions within the United States. By the end of the two-day lesson, students will be able to answer the essential question: “Were the issues brought up by the muckrakers effective in the passage of federal legislation? Explain by the use of the documents below and on your knowledge of the time period.” A new DBQ rubric (2015) is attached for grading purposes.
