Teaching with Historic Photographs: The Google LIFE Photo Archive

Google has posted ten million photographs from the LIFE photo archive on their online gallery of images. It's a great source of material for teachers and students who support a document-based approach to teaching history. 

While I wish that Google had done more to curate the collection with robust search tools and more specific categories, I think that teachers will find it to be an invaluable resource to enable students to "be the historian."

I've put together this quick guide to help you get started.

1.  If you are unfamiliar with the document-based approach to teaching history, you might want to start with a quick visit to my web site Teaching With Documents. There you find many resources including Document-Based Questions (DBQ) for  students grade 2 – high school. Of particular interest are these Student Analysis Guides and for more detailed analysis – my Reading a Visual Document: Guiding Questions. (55KB pdf)

2.  If you are interested in how historic documents can be used to support literacy and critical thinking, visit my sample:  Homefront America in WW II.  It shows how to improve content reading comprehension with source documents framed around essential questions that link the past and present. 

3.  Now that you have some instructional background in using historic photos – it's time to visit the LIFE photo archive hosted by Google. It's organizes images by era and subject. Once you click on an image you get a brief description and some labels (tags) that allow you to find similarly tagged images. 

Lange For example here's one of the archive photos taken by Dorothea Lange in the Migrant Mother Series. It makes a great contrast to the iconic photo she took that day that is more commonly reproduced in textbooks. (You might ask your students which of the five photos they would choose, and why?)

The LIFE archive includes this description with the photograph: Migrant mother Florence Thompson & children photographed by Dorothea Lange.
Location: Nipomo, CA, US
Date taken: 1936
Photographer: Dorothea Lange

And LIFE archive uses these labels for this photo: Lange, Dorothea, Mothers, Fsa Photographers, Us, Tension Or Worrying, American, Poverty, Florence Thompson, Photography By, Migratory, Farmers, California, Expressions, Agriculture, 1930s
4.  If you don't already use Cooliris, I suggest you download this free browser plug in. It presents the photos in a broad panorama that  allows you to scroll through many images.  I've embedded a short clip below of Cooliris in action, so you can see how it can transform your browser when searching for images and videos on Cooliris supported websites.

5.  And remember that all Google image searches allows you to specify image size with this drop down box in the upper left of the screen.

Why Study Algebra?

Today I listened to NPR's Scott Simon and Keith Devlin of Stanford University, answer the question: Why Do We Need to Learn Algebra? (NPR Weekend Edition Saturday~February 28, 2009). Devlin described how spreadsheets have become essential to managing everything from your finances to your fantasy football team. And of course, spreadsheet are basically collections of algebraic formulas. You can follow this link to the NPR story, comments and audio file. Teachers might use Devlin's comments as a springboard for getting students to think and discuss the application of algebraic thinking in their lives. 

 

Excel 

 

This is essential, since algebra is emerging as an academic gate keeper. I'm not a math teacher, but I suspect it stems in part from the fact that many students lack basic computation skills. But more importantly,  students have to be able to transition from concrete lower order thinking skills (arithmetic) to higher-level and more abstract thinking (algebra and beyond).  

 

As Doug Reeves has noted, "The single highest failure rate in high school is Algebra I. After pregnancy, it’s the leading indicator of high school dropout. The leading indicator of success in Algebra I is English 8. The Algebra 1 test is a reading test with numbers.”  District Administrator, April ‘05

 

If Reeves is correct, then this is as much a literacy problem as a math problem. Teachers of all content areas can pitch in to support the higher order skills (analysis, evaluation and creating) that will help students with more advance mathematical thinking.

How to Embed a Prezi Presentation in Your Blog

prezi

Please note that Prezi’s embed options have changed.
I updated this post on July 16, 2011.
 

Prezi is a great presentation software that replaces the lineal PowerPoint style with the ability to present text, videos and images in a unique zooming style. Here are samples of how I use Prezi in a variety of settings.

Here’s How to Embed

1. Open your online Prezi presentation and look for the Share tab (lower right in this screen shot.) Click share.

 2. You will get the dialog box below. When you choose “</> Embed” tab the dialog box expands and reveal your embed settings. You may want to adjust the pixel size to fit into your blog columns. Copy and paste the html code into your blog.

Wiimote Interactive IR Pen Whiteboard Solution

It's only been just over a year since Johnny Chung Lee's first posted his creative solution for turning a Wii remote into an cheap interactive whiteboard system. Watch Johnny Lee's original IWB video.   

Last week, Stan Merrell and Adam Wilcox - two of my Rochester NY tech buddies, met fellow Rochestarian – Tino Agnitti. Tino has developed a great Wii mounting bracket and IR pen that makes assembling Lee's Wii creation a snap. Tino calls his IR pen "The Groove" it's a sleekly designed, 2nd-generation IR pen that features – Hybrid Activation Tip Switch and Button, Treated LED for better tracking, Vishay TSAL6400. It runs on AAA batteries and it works great. I was especially impressed with its very intuitive interaction with writing applications. Tino also created "The Spot," a mount to connect your Wii remote to a standard tripod with a 1/4" – 20 thread.

Tino sells his Groove/Spot combo for only $39. Spend another $39 for a Wii remote (no need to use the rest of the Wii system) and you have an interactive whiteboard on any flat surface you choose to aim your  LCD. Tino showed me how to  aim the Wii at my monitor and we turned my MacBook into a tablet! 

Software? For PC, Tino recommends Smoothboard produced by Boon Jin Goh, a friend who lives in Singapore.   Tino set me up with the Mac version – Wiimote Whiteboard that I'm running. It comes out of Germany from Uwe Schmidt, a master's student at Darmstadt Technical University.  It was a quick install and it's especially easy to calibrate. For more on the growing wiimote community check out The Wiimote Project Forum  

I'm working on integrating the wiimote system into a portable whiteboard that I can use in my presentations. I'm very excited about pairing it with Prezi – its zooming capabilities will allow me to do exciting nonlinear presentations.

Prezi – Engage Your Audience with a Zooming, Non-Lineal Presentation

I’ve been having great fun with Prezi a new web-based presentation software currently in private beta mode. (You can submit a request to be included in the beta.) Prezi allows you to easily create maps of texts, images, videos, PDFs, drawings and present them in a nonlinear way. The menu for adding elements has a very unique navigational approach. (Easier to experience than describe.) Once you’ve added your text and graphics you can define a path through the material. But you can also click on any element in the presentation and zoom until it fits the whole screen. Likewise you can zoom out to reveal the larger presentation canvas. Here’s a link to the Prezi online manual. 

Once completed the presentations can be saved on the Prezi server or downloaded to your computer as a fully functional file set for presentation. (Once downloaded to your computer the presentation is no longer editable.) Prezi will host your presentation to share with others via the web. You can set permissions open up or limit viewers. You can even collaborate by allowing group editing. 

I’ve been working on a brainstorming Prezi (embedded below -click arrow to play). You can click on any element to fully enlarge. For example, click on the image of Ben Stein and the video clip will play. Click on any of the bracket or circle frames and the defined area will fill the screen. Hold down the “R” key on your keyboard and the left mouse will rotate the screen. Use your mouse wheel to zoom in or out. You can explore the presentation using your mouse to pan and zoom or use the path I defined by using the arrows in the lower right. There you will also find a fill screen icon. Here’s a direct link to the presentation.
