The Student As Historian – DBQ Resources and Strategies

New woman-wash day Over the last few weeks I’ve been guiding teams of teachers on reflective classroom walkthroughs. During the course of one of our “hallway discussions” I asked a social studies teacher, “who’s the historian in your classroom?” After a bit of give and take, we concluded that in the traditional classroom, the students get to watch (and listen) to the teacher be historian. 

That’s certainly what you would have seen early in my teaching career. I was the one doing most of the reading, reflecting and synthesizing of historic material. I thought my job was to distill it all and simplify for consumption by my students. It took me a few years to realize my job was to get the students to do the thinking.  I have spent my career developing teaching strategies and assembling resources that foster the student as historian. 

This downloadable SlideShare accompanies my workshop in “Teaching with Documents.” Don’t think of it as a presentation. It’s a online guide to resources and includes strategy illustrations from my workshop.

Humanities Conference Smackdown! AHA vs MLA Twitter Visualizers

What a weekend for humanist scholars – two big annual conferences under way – the American Historical Association (AHA) Boston and the Modern Language Association (MLA)  LA. I thought it would be interesting to create two visualizers to follow the key words being used in Tweets from both conferences. Watch the memes emerge! The first shows the word frequency of tweets using the hashtag #aha2011 and second follows the hashtag #mla11. 

(1/13/11 Note) Since these visualizations are time sensitive, I have posted screen shot versions of each. For the next few weeks you can click on link to live versions.

Historypin – Make DBQs with a Digital Time Machine That Layers Image, Story and Location

While planning for my next document based question (DBQ) workshop, I discovered Historypin. It’s a great mashup of digital photos with stories layered over Google maps. Users can search images by geography / time and post historic photos with stories to maps. It’s fascinating to view historic photographs set against the backdrop of current Google map street view.

Historypin

Here’s a circa 1894 photo I uploaded to Historypin showing a bridge crossing the Erie Canal in downtown Rochester NY. It’s layered over a functioning “street view” in Google maps.

In Historypin’s story section, I provide a brief history of the canal’s impact on the growth of the city.

Then I pose a question. “I wonder if the people in the old photograph still appreciated the canal’s role in creating the city of Rochester, or if they had come to see it as outmoded nuisance which divided the city in half?”

For more ideas for classroom see:  image guide | story guide | teachers’ notes. 

What I like most about Historypin is that it adds a new dimension to the DBQ approach to instruction – students don’t simply learn from historic documents – they get to document their world for future generations.

More from Historypin:

Historypin was created as part of our current campaign to get people from different generations spending more time together. From a lot testing, we found old photos are a great way of getting people talking about how their street used to look, what their grandparents were like and what’s changed (or not) over time. 

We decided to create a website where people everywhere could share their old photos and the stories behind them, pinning them to a map of the world. We also thought it would be neat if you could compare these old photos with how the world looks today, making the site a bit like a digital time machine. So we asked Google if they’d help. They let us use their map and Street View functionality and helped us build the site. 

The great thing about Historypin is that when they’re using the site, loads of people are spending time with someone from a different generation. Older people have attics full of old photos, younger people know when to click and when to double click.

How To Quantify Culture? Explore 500 Billion Published Words With Google’s Books Ngram Viewer

By now you must be aware that Google has been busy digitizing books – over 5 million are now available for free download and search. Recently Google Labs has made public a giant database of of names, words and phrases found in those books (along with the years they appeared). It consists of the 500 billion words contained in scanned books published between 1500 and 2008 in English, French, Spanish, German, Chinese and Russian. 

Google Labs has just posted the “Books Ngram Viewer” – a free online research tool that allows you to quickly analyze the frequency of names, words and phrases -and when they appeared in the digitized books. You type in words and / or phrases (separated by comma), set the date range, and click “Search lots of books” – instantly you get the results. Note: when “smoothing” is set to “0” the results will show raw data. Using a higher number produces an average – example “4” will give you four year running averages that will more readily display trends. 

In this graph I searched “horse, carriage, canal, train, steamship, bicycle, car, airplane” and set the date range to 1800 – 2000.  Link to this transport graph at Books Ngram Viewer The results offer some insights into when these new transportation terms found their way into print. 

Transport-1

I think Books Ngram Viewer has many interesting applications in the classroom. The first that comes to mind, is as tool to introduce the research method – form hypothesis, gather and analyze data, revise hypothesis (as needed), draw conclusions, assess research methods. Working in teams students can easily pose research questions, run the data, revise and assess their research strategy. Students can quickly make and test predictions. They can then present and defend their conclusions to other classroom groups. All skills called for by the new Common Core standards.

Using the Ngram viewer, will enable students to discover many insights which will require revisions to their research strategies – a great way to explore word usage, social context and statistics. Words have multiple meanings. In my transport example “car” appears in the graph long before the advent of the automobile. Was it used as railroad car? In contrast to newspapers, events and trends take time to find their way into books. “Pearl Harbor” does not reach a peak until 1945.

The frequency of occurrence scale is important (vertical Y-axis.) If you graph a high frequency word against a low frequency word(s), the low is reduced to a flat line at the base of the scale. (Abraham Lincoln and Marilyn Monroe) Remove the high frequency (Abraham Lincoln) and re-run the graph – the low frequency (Marilyn Monroe) will appear with more detail.

Updates: 

NGram Viewer has added a * wildcard feature. More on how to use it here.  Hat tip to Jean-Baptiste Michel of the nGram team who emailed me “In English, the data is good in 1800-2000, but not really before or after. Past that date, it looks like the composition of the corpus is changing; trends would indicate a shift in the corpus, not a shift in the underlying culture. So really, one shouldn’t look at data past 2000 in English.”

Analyze societal values: “ex wife, ex husband”  
 Changing laws and social values?
Watch the change in the Y-axis scale – add “my ex” to the original graph.

Track trends: “latte, sushi, taco”

Turn Your Students into Data-Driven Decision Makers

How is your educational technology being used? Teacher in front of the class lecturing on the smartboard? Or are students using ed tech to analyze, evaluate and create in ways that were not previouslypossible. I’ve written about one example, Wordle, a free Web 2.0 tool that enables students to interpret, qualify and visualizes text in new ways.

Another powerful data visualizer is the Motion Chart. It’s a dynamic flash-based chart that explores multiple indicators and visualizes growth over time. Gapminder World has assembled 600 data indicators in international economy, environment, health, technology and much more. They provide tools that students can use to study real-world issues and discover trends, correlations and solutions. Here’s Gapminders’s Hans Rosling showing how teachers and students can use the free Gapminder Desktop to develop there own motion charts using Gapminder data. 

To download a free version of Gapminder Desktop and access more educational resources go to Gapminder for Teachers. If you would like to build motion charts using your own data visit Google Gadget Motion Chart. (It’s the engine behind Gapminder.)  Motion Chart is a free gadget in Google Spreadsheet. In Motion Chart you can convert your data-series into a Gapminder-like graph and put it on your web-page or blog. All you need is a free Google-account. More info on Motion Chart 

New educational technology does not automatically improve the quality of instruction. We have all sat through dull PowerPoint presentations that were as “mind-numbing” as an overhead. Our return on technology investments may not be tracked in test scores that simply measure lower-order recall of information. A better metric would gauge if an educational technology gave students the tools to analyze, evaluate and create as professionals do. All skills demanded by the new Common Core standards.
