BBC Dimensions: exploring the human scale of events and places in history

Data, Mapping, Maths, Social MediaPublished on5 Comments on BBC Dimensions: exploring the human scale of events and places in history

Dimensions is an experimental project from the BBC that allows you to compare the scale of different types of events with something that we can all recognise. There are two parts of the project “How many really?” and “How big really?“

“How many really?” is all about the numbers of people that were involved in a whole range of different events throughout history. The tool allows you to either add in your own numbers, for example 30, the number of children in your class, connect with Facebook or Twitter and compare your networks or even the number of people who can board a double decker bus or a Boeing 747.

You are then shown a visual comparison with the number of people involved in the event that you have chosen. The events fall into the following categories:

  • Battles
  • Civilisations
  • Current Affairs
  • Disasters
  • Diseases
  • Entertainment
  • Modern Society
  • Religion
  • Slavery
  • War

“How big really?” is all about getting a better understanding for the scale of different historical events and locations compared to our own map location.

We want to bring home the human scale of events and places in history. The D-Day landing beaches measured from London to Norfolk in the UK. How far would the Titanic stretch down your street?

Dimensions simply juxtaposes the size of historical events with your home and neighbourhood, overlaying important places, events and things on a satellite view of where you live. Certain “Dimensions” can be transformed into short walks, so you can get a physical appreciation of the distances involved.

The tool provides a range of example categories to explore including:

  • The War on Terror
  • Space
  • Depths
  • Ancient Worlds
  • Environmental Disasters
  • Festivals and Spectacles
  • WW2 – Battle of Britain
  • The Industrial Age
  • Cities in History

From the Ancient Worlds category you can place all sorts of significant monuments, like the Colosseum, on top of your own location. It gives you a true understanding of the scale of these structures. This would be great for classes to begin to really appreciate these huge monuments. What would be even better would be seeing a 3D model – as in Google Earth or Maps – on your location and then being able to pan and zoom around it.

The Dimensions tools would be interesting to use within a history class but also within maths to help children and classes get a better appreciation of different sizes. It will eventually be integrated into the online history resources at the BBC depending on user feedback.

TEDx Talk: What we learned from 5 million books

Data, Google, MathsPublished onUpdated on3 Comments on TEDx Talk: What we learned from 5 million books

I discovered the Google Ngram Viewer from this TED Talk by Erez Lieberman Aiden and Jean-Baptiste Michel who are both fellows at Harvard University and Visiting Faculty at Google. They created the tool to analyse the millions of books being digitised by Google to allow them to search for cultural trends.

Using the Ngram Viewer would certainly be an interesting data handling lesson for children!

A History of Teaching and Learning from 500 Billion Words

learning v teaching

 

By analysing over 500 billion words the Google Books Ngram Viewer allows you to compare the history of terminology and language from approximately 5 million digitised books.

The graph above shows my search for the terms “teaching” and “learning” in publications between the years 1500 and 2010.

What fascinates me is how the popularity or usage of the different terms climbed and fell throughout this period. The term “Teaching” has been used more frequently since the turn of the 18th century, somewhat settling into a plateau in the last 60 years. In comparison the term “learning” seems to have more of a rollercoaster frequency in the last 500 years.

References to “learning” from 1800 fell notably in the following 100 years, to a point where “teaching” was referenced more. And then began a 75 year period where “teaching” was clearly more frequently used or referred to in published literature. Why would there have been such a decline or change in frequencies?

If you look at the references to “learning’ there seems to be some peak and trough pattern amidst an upward trend. I wonder why this was the case? Similarly why did references to “learning” fall away at the turn of the 19th century only to climb steadily again in the last 100 years? What perceptions of “learning” or cultural differences were there between the 1700s (“learning” references increase) and the 1800s (“learning” references decrease.)?

I am no historian and I am sure many of you reading this will be able to explain the information better than me – needless to say it would be interesting to explore any broad reasons or background that might effect such results.

One Question Surveys – What do you want to find out about?

DataPublished on3 Comments on One Question Surveys – What do you want to find out about?

I have started a little project that wil post some simple surveys on education and/or technology. The Apple v Android survey managed to draw well over 1000 responses and I would like to attempt the same for a wider group of questions.

Go to >> http://onequestionsurveys.posterous.com

1qsurveys

You can do three different things on the site:

>VOTE – add your preferences or votes to open surveys

>RESULTS – explore the outcomes of the completed surveys and add your comments, results will be published after 1000 responses – chunky results!

>SUGGEST – make a suggestion about a question to survey, I will try and make as many worthwhile questions active surveys as I can. In fact you can make a suggestion in the form below right now – it could be anything from preferences, tech choices, future of education, other school or tech related issues.

I would like the survey outcomes to be used in combination with each other so that they might form a wider picture of an issue. For example after a time you might pull all the mobile surveys together or all the results tagged “curriculum”. All the content is CC-A-NC-SA licensed so you can use them in your presentations or blog posts.

I hope you can lend your support to this little project.
