Demonstration of What's the Difference?

This is a transcript of a QuickTime movie (12.7 MB) recorded at the Macquarie ICT Innovations Centre in 2006 when Carol Oliver, from the Australian Centre for Astrobiology, demonstrated one of the virtual field trip tools, What's the Difference?, for high school students.


You can see down the bottom there you can just hit Create New Dataset if you want to. You just name it and you’ve got your own dataset. I’m going to show you one I’ve pre-cooked in the oven and it’s this one here. So you just hit, that will be the name of your dataset up there, just hit Create files and just imagine this is like two axes and that’s you x and y axes. On one side, this is just straight typing in, the things that you want to compare. Now this can be a minimum of two windows. You need two to compare but you could fill up all of this side if you wanted to. I’ve done four because there are actually four windows that you can compare at any one time. And on the other side you put what you want to compare the attributes, all right? So you continue to the next step and you’re faced with this sort of scenario. All the red dots mean they’re empty sets. There’s no information. All the green ones mean they’re full of information. That means it’s got a visual file in, it’s got the glossary words and it’s got information. I’ll show you that in a moment. Yellow ones mean one of those three things is missing. Now it might be that I don’t want a glossary word in and I want the yellow spot there. That’s okay but it just reminds you about that. So if I look at a green one that’s already been done, you can see there, this one here, you’ve got the movie. You can use any kind of visual. It can be a movie or a jpeg or a gif image or a psd image, whatever, it can go in there. And when you choose a file you choose the file this specifies and it will all come down, downloaded into the file. You find the file and you just fill it up with the information you want, all right? Now actually I’ve managed to wipe that one out so I might actually choose a file, I had emov, choose the file, just hit OK, back, all right?

Here I’ve made some glossary words and that’s just straightforward typing and in the bottom, again, I’ve put some straightforward typing and when I’ve done that, filled up the whole, I say Save and it tells me that’s fine, okay? Now just let me show you a yellow dot, what happens. Okay, in here there are no glossary words and it says you have not filled in a glossary word. Well I don’t want one, thank you, and then it tells you a yellow dot will be there because of that. Okay, leave it like that. Now your menu, build application and it’s as simple as that. That’s how you put your data in.

And now we’re going to see how that looks now you’ve put your data in. As I said, there are four windows. I can tell you just about every class that’s been through here, about fifty to sixty percent have missed this part out. I don’t think it’s particularly obvious but these two blue dots here produce your other two windows. So just click the one out from the other and move them around as you want, okay? Now you might want to move them all the way off to the side there because the very first thing you want to do is choose the categories. Now I said in my case it was four, ancient and modern Mars and ancient and modern Pilbara. So I can choose here whichever order I want to do that in. Ancient Pilbara over here, just move this over here, ancient Mars, that is a movie, okay? Just see if we can hear it. Don’t worry about it, you’ll hear it with earphones. Okay, so we were looking at Composition. I was showing you, you can see a movie going on over here that I’ve put in and you can see these things have come up. It was this one here that I just entered the file on, all right? Here are the glossary words that were there. I’m just mousing over them to remind me of what they were. And there are the little boxes of information that you just type in, all right? You can do, this tells you where you are, you can also do a pre and post test as well and you can also set a hypothesis if you want to.

So let’s just go through this information and you can see how it presents in many different kinds of ways. You can go and explore that. There’s a little dust devil going across Mars. Virtual reality allows you to do this, allows you to do this and surface fly by, okay?

So now what I want you to do is launch this one, okay, and it has exactly the same database except it will just simply come up with that database I’ve just shown you. And it will come up like this. It just takes a moment to load and remember you’ve got the two little windows down here. Pull them off to one side and then get on with choosing your categories, okay?
