A document camera makes a great addition to a history classroom with a video projector or TV. A document camera captures anything under its lens and projects it on the screen. While this technology has been around for a few years, I have noticed it has been a little slow to catch on for a variety of reasons.

Some teachers may be hesitant to embrace the document camera because they believe it to simply be a glorified overhead projector. The document camera beats the old overhead projector in many ways, the first being that the document camera does not require one to make transparencies. A teacher can project artifacts, photos, worksheets, and anything else that can fit under the camera lens. In addition, students are better able to see the image produced by a document camera as it is much brighter and clearer than the image produced by the overhead projector. Best of all, you no longer leave school covered in overhead marker!

The cost of the document camera may also make this teaching tool seem out of the reach of many teachers and districts in these lean budget years.

While document cameras range in price from $200 to $2,000, this should not preclude one from having their own document camera. You can find a used document camera on eBay or a surplus property store for under $100. I bought mine at one such surplus property store, associated with the
University of Maryland, for $25. Another option is to make a document camera yourself using a webcam and available USB port. The only drawback to this setup is you have to be able to load software on your computer attached to the video projector in your classroom. A ready-made version of this runs about $69. It is also possible to obtain grant money for document cameras from places like DonorsChoose.

Once you have your document camera installation is straightforward. Some document cameras come with a freeze image button which is a great feature to capture a page in a book or map that might be difficult to hold in place. If the document camera does not have this feature, you can hook up the document camera directly to the video projector, which often has the ability to freeze an image. If your document camera is not one that hooks up to your computer via USB, you can also set up the document camera directly to your projector. This allows you to toggle between the image on your computer screen (assuming it too is attached to your video projector) and the image from your document camera. You can also connect most document cameras to a television using an S-video cable or component video cable. It should be noted, however, that the clarity is not as crisp when using the S-video cable or component video cable compared to using a VGA or DVI connection.

The document camera has vast instructional possibilities. I have used my document camera every day in my history classroom. One of the benefits of having a document camera in a history classroom is having the ability to analyze primary sources together as a class. I am able to zoom in on important components of a photograph or text and can invite students to the document camera to annotate pictures or text without bulky markers or transparencies. I am also able to share maps in books easily with students, in color. Students are able to share work they have created immediately with the class without having to scan an image or make a transparency of the document.

This means that jigsaw activities work very efficiently, with each group able to share what they have written on nothing larger than a worksheet. Collectively, classes have created essay outlines and timelines together. The document camera allows students to share storybooks they have created, projected large enough for the class to see. From a classroom management perspective, the document camera allows me to easily show students the worksheet we are working on or the question I want them to focus on. I am also able to place my stopwatch under the camera to show students how much longer they have to complete a task. Finally, my favorite use of the document camera is allowing me to spotlight and share exemplar student work. I am able to give specific praise to a well-written essay or project.

I hope you are able to get your hands on a document camera and share your tips and tricks with others. You can find product reviews for document cameras in this article from Scholastic.

With the National Archive's DocsTeach, educators can find primary sources and the tools to present and interpret them on the same website.

Officially launched September 20, DocsTeach brings more than 3,000 primary sources together with seven online activities, each designed to reinforce specific classroom skills. Register for free, and log in to browse or search the site's photographs, speeches, letters, drawings, memos, video clips, maps, and other sources, dating from 1754 to the present day. Bookmark those that interest you, and head over to the site's "Activities" section.

Here, you can incorporate your chosen sources into online activities adaptable to students at all grade levels. Save activities to access later—including in the classroom.

Activities include:

• Find a Sequence: Have students arrange primary sources in a particular order. DocsTeach suggests using this activity to prompt students to determine the chronological order of sources, or to order steps in a process (for instance, which documents represent which steps in the veto process? In the drafting of the U.S. Constitution?).
• Focusing on Details: Use five different tools to focus student attention on specific sections of a primary source. Do you want your students to focus on a certain facial expression before being distracted by the rest of a photograph? Use "Zoom/Crop,” "Spotlight," or "White Out/Black Out." How about removing a few key words from a document and having students determine, from the context, what they might be? Or pointing out the date and other contextualizing evidence in a handwritten letter?
• Making Connections: Arrange primary sources in a particular order, and have students write arguments for why one source leads to another. Choose sources that lead up to a major historical event—a telegram on the shelling of Fort Sumter might lead to Abraham Lincoln's suspension of the writ of habeas corpus, for instance. Or maybe your sources are thematically related—a 1918 poster using a woman in uniform to recruit male Marines leads to a 1942 WACC recruitment brochure leads to a 1990 poster calling women to join the U.S. Army
• Seeing the Big Picture: Match primary sources in related pairs. As students successfully make the matches, they reveal pieces of a larger picture. How do the matched pairs relate to, say, the image of the Declaration of Independence or the 19th Amendment?
• Interpreting Data: Call out particular data points on primary sources incorporating charts and graphs, and embed comments and questions in the source. Guide how students react to the data they see and lead them to ask who gathered it, how they gathered it, and why.
• Mapping History: Use a modern or historical map as a background, and have students place sources in the location they come from or relate to. Where do sources locate New Deal projects? Major battles of the Civil War? Protest marches throughout U.S. history?
• Weighing the Evidence: Present students with primary sources on a particular historical issue, and have them decide whether they support one interpretation or another. Try the causes of the Civil War. Which documents support an economic cause? Which support slavery as a dividing issue?

Write introductions and conclusions to any activity, and publish them to share with other DocsTeach users, if you choose. Or check out the National Archives' sample activities.

At present, only 28 pre-made activities are available, but check back as more users register at the site and share their work.

Ever tried teaching with technology? No, we don't mean Twitter, Facebook, iPods, cutting-edge interactive whiteboards, or even video and DVD players.

We mean patents.

The U.S. Patents and Trademark Office and Google Patents stockpile millions of patents, dating from 1790 to the present. In a July 2010 Organization for American Historians article, Chemical Heritage Foundation fellow Cai Guise-Richardson suggests ways to mine these historical document collections for classroom use.

Maybe you're studying Eli Whitney's cotton gin. What did the original patent look like? Can students decipher what the device does and how it works from the diagrams alone, or is it unclear? What sort of language does Whitney use to describe his invention, and how does he think it will help society?

Ask your students to think about the technology they encounter every day. Do laptops, MP3 players, cars, phones, household appliances—even toys—ever stop changing? No—there's always a new model or a different brand to buy. Inventions in the past developed in the same way. Try a Google Patent search for "cotton gin" to discover just how many variations and improvements on Whitney's invention eager inventors have developed since 1794, when Whitney first patented his design.

Try an advanced search using a word and a date. In 1901, were there any patents containing the word "genetics?" Probably not. What about in 1954, the year after scientists Watson, Crick, and Franklin discovered the structure of DNA? How about in 1990?

Think of other terms that might show up frequently in patents in different time periods. Is "bomb shelter" more frequent after World War II? How were radioactive substances used before they were proved dangerous? Consider this 1925 patent suggesting that rendering food and water radioactive will help prevent disease and preserve freshness. Do students think we're using any inventions today that we'll wish we hadn't in the future? What sorts of words and phrases do they think would show up frequently in patents today?

Pick a phrase or an invention and start exploring! Refer to Guise-Richardson's article for more suggestions if you have difficulty searching or run dry of ideas.

The Picturing America website, created by the National Endowment for the Humanities, presents 27 iconic images in American history designed specifically to encourage educators to use images as primary source documents in the classroom. The images range in time from 17th-century depictions of the Catholic mission in San Antonio to the contemporary art of Washington, DC native Martin Puryear.

The printed materials are no longer available, but you can read more about the online resources here.

The Museum of the Moving Image presents The Living Room Candidate, an online film exhibit of campaign commercials from Dwight Eisenhower through the current election, highlighting issues from bomb shelters to race to economics, war, and poverty.

As David Schwartz, Chief Curator of the Museum of the Moving Image, explains in his introduction to Curator's Choice selections,

An effective campaign commercial works on several levels. It must make an effective argument, either for or against a candidate. It must work on an artistic level, using the tools and techniques of filmmaking to capture viewers' attention and stay in their memory. And it must work on an emotional level, creating a connection with the voter. While a strong advertising campaign does not guarantee election, it often does indicate which candidate has a clearer and more effective message. It is not surprising, therefore, that in most years, the best ads also happen to be in support of the winning candidates.

The site is directed toward high school students and educators and includes eight lesson plans on topics such as the language of political ads, television advertising, an analysis of the political ad as a mini-film, and a session on the process of producing a political commercial.

The Museum plans to continue to add lesson plans and interactive activities for classroom use or independent study.
