What is it?

For students in high school today the events of September 11 belong to the past, but they may very likely encounter the yearly commemorations of those events on television or social media or they may have seen a physical memorial either in their area or while traveling. The past regularly enters our daily lives in this way and this is distinct from history. This guide explores commemorations, memorials, and monuments of the September 11 attacks to help students identify and recognize how they engage with the past how that process differs from history. 

Key points:

• This activity will take one 90-minute period or two 45-minute periods. It is appropriate for a high school U.S. history classroom, but can be modified for a variety of learners.
• Students will analyze, interpret, and evaluate primary sources. 
• Students will learn more about the events of September 11 and also how those events exist in public memory. 
• Guiding Question: What's the purpose of commemorations and memorials 

Introduction

History is the process by which we try to better understand the past, but history is not the only way human beings use the past or make meaning out of past events. This guide looks at another process of remembering the past through commemorations and memorials. Specifically it looks at the commemoration of and memorials to the September 11, 2001 attacks in the United States in order to help students identify the differences between commemorating past events and studying those events historically. While the events of 2001 seem quite recent for some of us, they are far enough in the past to begin to be considered as history — especially for students in high school today who are too young to have been alive when these attacks occurred. Analyzing how various commemorations and memorials engage with the past will help students recognize the difference between this engagement and history while also understanding better the place the events of September 11, 2001 in public memory.

Write on the board: What is a commemoration? Can you think of examples? 

If students are struggling with this prompt, add related words that they might be more familiar with such as “memorials” or “monuments”. Explain that memorials and monuments are specific kinds of commemorations. Have students come up with 5-10 examples of their own and have them note what event is being commemorated by the memorial.

Background/Context

[This can be read to class, assigned for the class to read ahead of time, or you can substitute another resource such as the FAQ from the National 9/11 Memorial and Museum.] 

On the morning of September 11, 2001, a group of 19 men forcibly took control of four separate commercial jet airliners. The first two planes struck each of the World Trade Center's Twin Towers [office buildings with more than 100 floors each] in New York City and a third aircraft struck the Pentagon — the headquarters for the U.S. Department of Defense — in Arlington, Virginia. A fourth aircraft crashed into an open field in Somerset County, Pennsylvania after the passengers and crew, having learned about the earlier attacks via phone calls they were able to make to family and friends, attempted to take control of the aircraft away from the attackers. In all 2,996 people died in the attacks. It was later learned that the attackers were associated with an extremist group, al Qaeda, then based in Afghanistan. The response from the U.S. government led to an invasion of Afghanistan from which troops were only withdrawn in 2021. The attack was also used to justify the 2003 invasion of Iraq. The attacks resulted in changes within the U.S as well, including new laws such as the 2001 Patriot Act, changes to airline security procedures, and even changes to the structure of the federal government with the creation of a new cabinet department, the Department of Homeland Security. The full effects of these attacks are still being felt today both in the U.S. and around the world.

Activity

Have your students examine the images below in the Primary Sources section. This can be done digitally with the links provided below or the sources can be printed out for students to examine physically. Each source is a photograph of a memorial to the September 11 attacks. The memorials come from different locations across the U.S. and were built at different times. Some are informal handmade memorials put in place immediately after the attacks. Others were planned monuments built several years later. Students should examine these sources closely and then work together to sort them into those memorials that were placed at the site of the attacks (either at the World Trade Center Towers in New York, the Pentagon in Arlington, Virginia, or the field near Shanksville, Pennsylvania). Students should then divide the photos into those that were placed in the immediate aftermath of the attacks (2001-2002) and those that were constructed later (after 2002). Students can make use of the information that accompanies the images on the Library of Congress page to make these determinations about time and location. 

This sorting can be done physically with printouts on four tables or desks or digitally with platforms such as Google slides or Padlet.

Once these have been sorted, prompt students to look for patterns by examining the photos closely. Provide the following questions for students to consider as they examine the images:

• What if anything does the memorial communicate about the September 11 attacks?
• What themes do they express or communicate? 
• Do they look similar to any other memorials you have seen? Which ones and in what way?
• How do the memorials and commemorations differ by time and location?

These questions could form the basis of a whole class discussion or students could discuss them in groups of 3-5 and report out. If the course is online students could post their responses in a discussion board in their LMS.

General Tips for Teaching Controversial Subjects

• Center activities on primary sources. Primary sources are tangible evidence that allow students to engage directly with history. These primary sources in particular were preserved and digitized by the Library of Congress because they were deemed important to the history of the United States.
• Discussion and analysis of these sources can be wide ranging, but within each class those discussions can always be turned back to the source itself.
• The sources are also, by definition, only pieces of a puzzle. They bring us closer to understanding the past but there is always room for doubt and uncertainty.  
• Questions, Observations, and Reflections should come from students. These are primarily student-directed learning activities. It is the instructor's role to create a space for inquiry and empower students to drive the inquiry.
• It may help to remind students at the outset that it is normal for different individuals to come to different conclusions, even when we are looking at the same sources. Further, it would be strange if we all agreed completely on our interpretations. This can normalize the strong reactions that can come up and enables educators to discuss the goal of historical research, which is to hopefully go beyond the realm of individual  perspective to access a fuller understanding of the past that takes multiple perspectives into account.
• Teaching historical topics that involve violence and other trauma can be traumatic for some students as well. Providing students with previews of what content will be covered and space to process their emotions can be helpful. The following video series from the University of Minnesota contains further tips for teaching potentially traumatic topics: https://extension.umn.edu/trauma-and-healing/historical-trauma-and-cultural-healing.
