Teaching about depressions with Google Earth

Pretty gloomy weather today, and Year 8 need to know about depressions tomorrow. Obviously my first thought is to go with Tony Cassidy’s Postman Pat lesson - a slice of Radical Geography genius. And so I shall, however fortunately, the UK is in the grip of a series of low pressure systems and the Weather Layer in Google Earth is brilliant for illustrating the relationship between air masses and the weather.

I could start with an animation of the clouds over the past 24 hours…

The animation requires a download of this network link

Turning on the Weather panel from the Layers Panel in Google Earth provides really helpful information.

Starting with the Conditions and Forecasts, the weather is cool over N. France, warm and rainy over the S. of the UK and cold and partly sunny over the North. Excellent!

Activating the clouds layer reveals the reason - a perfect example depression is responsible. More good news!

Finally, the rainfall radar indicates where the rain is falling. Conveniently within the warm sector of the depression. Absolutely textbook - yay!

I’m archiving the passage of this depression to provide material for a PowerPoint in case the weather isn’t being so cooperative next time I do the lesson.

Right, over to Postman Pat!

Teaching Sphere of Influence with Google Earth

Not the most interesting geographical concept to teach at GCSE, so I made a nice little Google Earth file to demonstrate the idea to my students.

First I created a placemark for my house, then I added polygons to represent the area that I visit in order to use various services.

Then I used the KML circle generator to create circles based on the maximum distance I am prepared to travel to use a particular service. I centred the circle on the service, and used the Ruler tool to estimate the distance in meters to my house.
The circle colour and width was edited in the Properties dialogue to make them stand out better - the default is a thin red circle.

During the lesson I started with all the information turned off (apart from my house placemark). I turned on the polygons one by one and facilitated a discussion about convenience / comparison goods, range and threshold population. I then added the circles to demonstrate the concept of sphere of influence.

The lesson seemed to go very well. Here are the resources I used (neither of which would be relevant to any other school - but feel free to adapt etc)

And here’s a worksheet I made for the lesson. (This is a Foundation sheet - more able students were given an edited version.)

iPhone Apps for the geography classroom

I can’t actually afford an iPhone however if / when I eventually acquire one, the first application I’ll install is Johan Nordberg’s Seismometer.

Seismometer records vibrations using iPhone’s built in accelerometer to “measure movements in two axes, calculate the resulting energy and draw the results on a rolling logarithmic scale.” There are many favourable reviews on the iTunes store and at 59p it’s somewhat cheaper than the classroom alternative.
In fact Seismometer would be perfect to use with my Shaker Maker - do it yourself earthquake table.

Other iPhone Apps that I’d like to try out include:

Earthscape:

Earthscape is a virtual globe, though resolution outside the US is fairly poor. It’s currently available as a free download. (iTunes link)

GPS Kit

GPS kit looks like an indispensible application to make the best use of the phones GPS. (iTunes link) It costs a few pounds though. I guess I just want to be able to replicate as many features of my Garmin Etrex as possible.

Aside from the three geography-related applications, I suppose I’d get some kind of Twitter client since my current phone is rubbish for that kind of thing. I also love the idea of the free WordPress application to be able to add and edit posts on my blogs rather more spontaneously than at present.

Neo-geography in the classroom

I’m exploring some ideas for a Neo-geography element to the geographical curriculum and created a new category for blog posts on the topic as I share my experiences from the classroom over the forthcoming months.

Neogeography at school

Neogeography at school

This week I deliberately used the term Neo-geography with my Year 7 class (11 years old). Over the course of two lessons we compared the merits of Google Earth/Maps and traditional Ordnance Survey paper maps.

Ed Parsons has commented on a recent BBC story highlighting the fears of the British Cartographic Society over “damage to future generations of map readers because this skill is not being taught in schools and people are simply handling geographical data” (err pardon - National Curriculum anyone?) Ed’s point that “one could argue for the need of a “new” cartography which adopts rather than ignores the capabilities of screen based maps to portray information dynamically” is a theme that is reinforced by the inspiring Richard Treves who I recently met at the Geo Education Summit at Google (and who drew my attention to Ed’s post)

Rising to the BCS’s bait, the students had little difficulty in identifying the merits of the two different approaches to mapping, indeed they showed rather more consideration of the issue than the Ordnance Survey reporting of the debate.  With no prompting at all, the students identified the principal advantages of Google Earth/Maps as:

1) Finding places quickly

2) Zooming in and out!

3) Display of geotagged photos (with GMaps Street View being a particular delight!) and 3D buildings

4) Display of real time information such as the weather

5) Free to use (though requiring a computer and the internet)

The Ordnance Survey map on the other hand offered the merits of reliability, light weight, plenty of detail, a key and cheaper running costs. The students were perfectly able to identify the user groups for the two different approaches to mapping. Ironically the Ordnance Survey advert featuring the mountain biker unintentionally reinforces the advantages of a Google Map - at least in one respect!

The students were delighted to learn that they were present on possibly the first outing of the  neo-geography word in a school classroom, and had little difficulty in appreciating the need for a term that describes the extraordinary potential of tools such as Google Earth to find out about, map and describe their world. The resolution of my school in Google Earth is sufficiently good that I can sit a student under a skylight in my room and locate them with a placemark accurate to centimeters. They gasped when they measured the distance from school to home - in centimetres, and enthusiastically collaborated on a map of their routes to school:

I’m not entirely sure that this activity was “damaging the future map readers”. Indeed they are really looking forward to recieving their Free Maps for School, thanks to the generosity of the OS. It would be great if we could have a copy of the local area as a KML overlay as well. In the meantime this site will have to do.

Google Apps - the next stage

Introducing Google Apps

Google Apps offers a way for students and teachers to communicate and share ideas easily. Of course you can share documents by email, but the reality is likely to be that students own computers with different platforms and software versions. Wikis are great for collaborative web pages, but a Google Apps community offers more privacy and is easy to set up. ICT managers at school may balk at first – the idea of students having a second email account and possibly access to IM Chat, may raise hackles. But we’re here to encourage students to collaborate, to improve peer assessment and assessment for learning and the tools provided by Google are in many cases superior to those offered by a VLE. They are also free!

Imagine then the possibilities…

It’s a weekend and your class is at home, from where they can access your learning community via a web page. Logging into their personalized area, they find their online documents as well as their email. The teacher has shared a basic revision guide with the whole class. Individual students can modify the guide, adding their own contributions to create a collaborative resource. The teacher can check the revisions to see which student’s have contributed.

Student A is finishing a piece of coursework. She shares it with her teacher who makes some annotations in a different colour. Both teacher and student are working on the document simultaneously even though student A has a PC, and the teacher a Mac.

Student B has lost his homework diary. He receives an SMS text from the online Calendar mentioning the deadline is for the following day. He cancels his engagements and stays up half the night finishing your homework!

Student C has produced a brilliant expose of the limitations of the Hoyt model. With her permission you share it with those students who need a little inspiration.

Student D is working on an assignment. He passes it to student C, his critical friend who provides a little input. He then shares it with the teacher. The teacher notes that student D has worked hard but also takes the time to commend the diligence of the critical friend, whose contributions can be seen on the page revisions history.

Student E loses their folder. However their coursework is safely stored online.

Student F does some brilliant research on Fair Trade. He shares his work with the teacher who publishes it as a web page. Student F notices the teacher is online, so contacts him via IM, and makes some corrections.

Setting up Google Apps

Starting from scratch, the first step is to visit the Google Apps homepage and sign up for a new account. At this point you can opt to register a domain name through Google. It costs £4.70 per year and avoids you having to worry about configuring your existing email accounts. I recommend this option! Once your new domain is ready you can sign into your Google Apps account dashboard and start building your community.

dash The dashboard

I began by creating a single test account. Once you are ready to set up accounts for a class it’s easiest to create a bulk list of user names. This can be simply done using a spreadsheet, saved as a .csv file and uploaded to Google Apps.

Your users will need to be able to access the learning community. I used Google Pages to create a web site for my new domain. The homepage contains links to other pages and learning resources as well as a Google Calendar for homework deadlines. It also contains the link to the individual user’s start page.

home A web page for a learning community

The start page is where the individual user can log into the community and can be wholly or partly customizable by the students. Here is the start page for my community. I have opted to create a lockable section with a link to their email and Google Docs as well as a small section for announcements and news.

start The start page for the community

The final stage would be to apply for an upgrade to the Education Edition of Google Apps, which will increase the opportunities for support, though you don’t get any extra features over the standard version. (Compare versions here)

Working with the learning community

The community is now up and running. Students have their own email address and Google account. They can create and share Google documents presentations and spreadsheets and communicate via email and IM chat (although this feature is suspended at the moment.) I can keep a copy of documents sent to me for assessment and share examples of particularly good work, or resources produced collaboratively by other members of the class. I can enter homework deadlines into my own Google Calendar which then appear immediately on the calendar on my home page. (Students can subscribe to this calendar and can even opt to receive emails or SMS alerts for homework deadlines!) I find it easier to give written feedback by typing directly into their documents and I think the students prefer this method of marking. The Google Apps community doesn’t provide full access to the many other useful Google tools, for example My Maps and Picasa. To access these resources a separate Google account is required, however students could easily sign up using their community email address. At this point, vast horizons of possibility open up, which extend of course, far beyond the realms of Google. I’ve always preferred Flickr over Picasa for example, and it would be good to see students exploring and selecting web 2.0 tools on their own.

What about the VLE?

At some point in the next few months our school will adopt a VLE. I don’t want to set up a system that will work in direct opposition, though I’m mindful of the limitations of the VLE implementations I’ve seen. I’m concerned that many VLEs seem to be little more than electronic filing cabinets linked to robotic assessment practices. Few commercial VLEs seem to truly promote a constructivist approach to learning, and I’m hopeful that teachers at my school will be able to use the best online tools for the purpose rather than being required to use less effective tools that are part of the VLE. Shared calendars and blogging tools are key examples. I see my learning community working alongside the VLE, neither replacing nor competing with it. The VLE will host the school website, user and assessment data and shared documents. The Google Apps community serves to encourage effective communication, assessment and collaborative practices while avoiding platform and software incompatibilities.

Google Apps presentation

I’m becoming more and more convinced by Google Apps. Here’s a quick presentation showing how it works for me. I recommend downloading the presentation from Slideshare as the images don’t resize well.

Google Apps for assessment - first impressions

Thanks to the lovely Doug Belshaw, whose recent posting on Google Apps for education insprired me to investigate further. I set up a Google Apps network for my Year 10 class with the aim of encouraging peer collaboration and improving the assessment process.  The process was simple since I already had my own domain (I used Juicy Geography, though on reflection should have created a new one through Google) I created a list of users in Excel and exported them into Google Apps with little fuss. I also put togther a simple start page from which the students can access their Google Docs.  I haven’t yet turned on the email or chat features since my school is contemplating the implications…

I can report some success with an essay homework that I set. Around a third of the class submitted their work via Google Docs meaning that I could edit, improve and comment on their work, and print off a paper copy for their files. The next stage will be to allocate the critical friends advocated by Doug and try out some peer assessment of an exam question. I’d like to try and integrate Google Calendar within my community and will hopefully activate the email option soon. I’m considering starting a new network under a different domain name, that could be easily expanded if other departmental colleagues wish to join.

There’s no question in my mind that Google Apps can be very powerful in supporting a learning community. I’ll report again on developments later in the year.
