What Maps Are Not

Calling your attention to two great blog posts by northierthanthou: “A Map is Not a Territory” and “Map Ain’t Time Either.” Both explore the judgments that are made by mapmakers, and how their decisions can mislead readers.

From the first, which discusses differences between a AAA road map that omits “Indian Country” sites and one that is specifically for “Indian Country”:

The issue doesn’t seem to be resolution. The Arizona and New Mexico map has a higher resolution than the one for Indian country. I somehow doubt that anyone hatched a plot to hide Tsaile from Ken. My guess, is that the criteria for selecting what to put on each map simply differs, and that the difference was enough to make Tsaile disappear (along with quite a few other things, actually).

And from the second, which discusses how various maps visualize Native American culture areas:

This placement on teh map isn’t from time immemorial; it begins at the cusp of the 1400s, give or take a bit, and that enables us to place their entrance into a sequence of events for the region. They were still settling into the total territory on this map when the Spanish began exploring the region, arriving well after their Pueblo neighbors. Knowing that helps to put the map in perspective. Not knowing that invites an a-historical reading of the map.

Questions to discuss with students: What do the maps you use in class omit? What do your mental maps omit?  When you’re designing a data visualization, what are the most important factors to consider?  Do click through to read the entire posts, if only to see the maps in question!

So Much Tech, So Little Time

“For me, despite my love of cool new gadgets, I always try to start from a place of what do I want my students to learn and what do I want them able to do. If the cool-to-play-with Google Glass or Apple Watch or other gadget isn’t the most efficient way to answer those questions then I don’t bring it into the class. I can’t promise I won’t get one for myself though.”

The Eschatology of Technology

Watters discusses the narratives of social transformation in which technology and its putative capacity for ‘innovation’ and ‘disruption’ has become embedded:

What interests me are the stories that the businesses tell about “disruptive innovation” because this has become a near sacred story to the tech sector. It’s a story of the coming apocalypse –destruction and transformation and redemption, brought to you by technology.

[Thoughtful post about the prevailing narrative of innovation in education.

Now in our third decade of publishing social studies titles, we at WorldView pride ourselves on being part of the *continuity* of education in this country. We provide quality content to teachers.]

How Do Polls Work?

By now, many of you have no doubt seen more presidential polling results than you ever wanted to see!  But too many people equate internet polls such as the one featured above (from cheezburger.com) with scientific polls conducted by major news organizations.  How can you tell which of them are valid measures of public opinion, and which are not?

Start with Project: Conducting a Poll in WorldView Software’s U.S. Government.  Try it out, and then critically evaluate the results.  Here are some guiding points for questions students should be asking about their data:

  1. What was the difference between the total population of people whose opinion they wanted to know and the number of people who actually answered the poll?
  2. Did people have a choice to take the poll or not?
  3. Could people respond to the poll more than once?
  4. Was one group of people more represented in the poll than another? Why or why not?
  5. How were the questions asked — did they notice they got a better response rate from one method over another, such as internet over in-person?
  6. How were the questions asked — did the questions use loaded language that hinted at the “right” answer?
  7. How were the questions asked — were they yes-or-no, multiple choice, etc.?
  8. and so on…

Then apply this methodology to the polls out there.  Count the differences between this poll from Breitbart (warning: overlay popup ad):

"You watched at home — now make your voice heard! Who won the third debate? Vote below to tell us who you believe was tonight’s winner: Hillary Clinton/Donald Trump"Donald Trump 52.82% (145,324 votes), Hillary Clinton 47.18% (129,785 votes)

 

 

 

 

and these polls, aggregated at RealClear Politics:

For a deeper dive into how polling works, visit the Pew Research Center’s Methods page.  There, you’ll find all sorts of information, such as how to figure out a poll’s margin of error.  Especially recommended reading: the overview “Flashpoints in Polling” by Claudia Deane, Courtney Kennedy, Scott Keeter and Kyley McGeeney.

UPDATE 12/06/2016: Very nice video from Scientific American explaining the math behind polling.
