Being critical




 Image above: Mannum Waterfall in South Australia (rarely with water these days but once upon a time it would have been a raging torrent). This geomorphology paradise is 70 kms outside of Adelaide on the way to Mannum on the River Murray. The rocks are at the edge of the Southern Australian Batholith with Migmatites prevalent. The waterfall has been a favourite fieldtrip location for geography and geology students in South Australia for many years.

 Critical literacy and websites

As a repository of websites and other resources to be used for geography teaching, this website frequently points teachers in the direction of websites. Most of these websites are not established for the classroom and may not have the quality assurances (QA) that educational sites would have. Naturally, websites from creditable organisations such as National Geographic and Government bodies would have undergone significant quality assurance (but still may be biased towards the governments or organisations goals/agenda). Recently I sent out a website called "History of conflicts". Thankfully we all don't just take for granted what the website represents. In this case I was alerted by a colleague that there was some inaccurate information on the site. Hence this posting on critical literacy. Whenever we get a website to use we should put it through the QA test and ask some tough questions in respect to origin, agenda, data accuracy and representational appropriateness.

Being critical may be defined as a challenging approach to the reliability, usefulness and bias of a source. It involves the questioning and challenging of the data, representations, attitudes, values and beliefs that lie beneath the surface of a source, in this case, geographically orientated websites.

To be critical is often associated with being negative or finding fault unreasonably but being critical should focus on:

  • careful or analytical evaluations
  • skillful judgement as to the truth or merit of something.
An ability of a person to be critical is sometimes referred to as a type of literacy (literacy meaning an 'ability to').

In the case of critiquing a website the following questions should be asked:
  • Who has gathered and curated the information on the website?
  • How much of it is fact and how much opinion?
  • Is the information biased? 
  • Is the data accurate?
  • Is the representation (map/graph) been used to distort the data?
  • Whose point of view and/or data is missing? 
  • Have appropriate representations been used? 
  • Is this an ‘expert’ opinion?
  • How objective is the information?
  • How do the opinions reflected in this information compare to that of other groups?
  • What are the values and attitudes implicit in this information?
To ask these questions is to be critical in a positive evaluative way. 
 
Credibility being something that is credible and is worthy of being believed because it has a high degree of accuracy. Some sources of information are more creditable than others. Newspapers and magazines vary greatly in their credibility as do television programs and the Internet. No source can be totally creditable; each has a degree of credibility which must be acknowledged and discussed to explain how it effects the conclusions.

Bias
being the misrepresentation of information to create a distorted view that could create opinions that are not credible. Much of the information we receive is biased in some way. It may not be so much what data is a website but rather what is missing. Taking a particular point of view and disregarding all other perspectives is a form of bias as is leaving parts of information out. It is always important to identify whose point of view or data is not represented, and why it is not presented in any information that you have.

Some sites to critique

Have a practice on some of these sites.  Are they creditable, objective and accurate. How would one know? At least we have to ask the questions!

Scooping geography




Making it easy to find teaching materials

The way forward for the curating and sharing of geographical sites is through websites such as Scoop.it (http://www.scoop.it/) and the communication network of Twitter.  As an educator one should join and share – you will be amazed by the number of fantastic resources and sites regularly turning up in your email inbox.  It makes life easier in preparing and researching for material to use in the classroom.

Scoop.it is a wonderful website with the potential to link into a wide range of geography orientated websites collected by individuals. It is also a great resource for teachers to curate collections of geographical materials found on the Internet.


Here is a great example of an educator (Seth Dixon is a professor at Rhode Island College and can be reached via Twitter @APHumanGeog) using Scoop.it to curate and spread outstanding geographical education sites and resources. The site is called Geographical Education and is at http://www.scoop.it/t/geography-education
“Global news with a spatial perspective: resources for educators and the inherently inquisitive.

Here is just a selection of Seth’s communication network in one week.
·           *  http://geographyeducation.org
*  SITES WITH THE CONTENT UPDATES:
      * Tumblr: http://geographyeducation.tumblr.com 

Here are some great cites ‘provided on a plate’ via Seth’s networks.

This database of global wars and conflicts is searchable through space and time.  You can drag and click the both the map and timeline to locate particular battles and wars, and then read more information about that conflict.  This resource would be a great one to show students and let them explore to find what they see as interesting.  This site is brimming with potential.     

The artistic collection entitled 'Landscapes' compiled  "the bizarre instances of cartographic dissonance inflicted by the Dutch government over their virtual lands. As Henner notes, the number of censored sites within the small country of the Netherlands is surprising, as is the technique used by officials to disguise them. Tracts of land deemed vulnerable to attack or misappropriation are transformed into large tapestries of multi-colored polygons, archipelagos of abstraction floating in swaths of open fields, dense forests, and clusters of urban development." 

This is an excellent review/summary of an edited volume that shows the value of geographic thought and its importance in the modern world.  This review conveniently gives a one paragraph synopsis of each chapter.  It does not need to be read chronologically, so you can pick and choose what you find relevant to your course.  The top 10 are (in order of inclusion in the book): the Idea of the Map, the Weather Map, GIS, Human Adjustment, Water Budget Climatology, Human Transformation of the Earth, Spatial Organization and Interdependence, Central Place Theory, Megalopolis and Sense of Place. 

This site shows how much space would be needed if the world’s population lived uniformly at the density of selected countries. It’s a good comparative use of spatial data. Here’s the original link:

This new resource, myHistro, combines interactive maps with timelines to organize stories, journeys or historical events as the move over time and place.  By embedding photos, videos and links this creates an incredibly dynamic platform for telling historical and geographic stories.  By combining these features, this is a powerful tool to create customized resources for you students.  Pictured above is a sample timeline that shows the spatial and temporal journey of the Olympic torch for the 2012 Games.   

There are plenty of regional biases about other places.  This map was generated by Google autocomplete.  If you Google, "Why is Rhode Island so...." if will automatically suggest some responses.  This was done for all the states and these autoresponses are quite revealing (and often humorous). 

Using satellite images to see change http://blog.americaview.org/search/label/Landsat
"With the help of satellite images fifth and sixth grade students at Mr. Tim Blum’s geography class at the University of Wyoming Lab School got a birds-eye view of how humans have impacted or modified their environments. Images acquired by satellites decades apart showed cleared forests, irrigated crop fields in the middle of the deserts, altered landscapes (new roads and water bodies), and urban growth."

In short, there is so much great teaching materials and hints up on the Internet now, programs such as Scoop.it and Twitter just help us find and curate what is good. In fact it comes to us on a daily basis instead of wasting time searching!!
