Collaborative Maps Update

In my last post I mentioned that, " I'd still like to see a SHARE button on Google Maps." Today I noticed that when I go to My Maps, I see a "collaborate" link at the top.



Clicking on it will let you invite others to collaborate with you on your map.



I'm not sure how long that feature has been there. (It was probably already there when I wrote my last post.) For now I'll just fool myself into thinking that Google liked my idea and decided to add this feature because of me. :)

It's worth noting that collaborating on a custom Google Map still requires users to register for a Google Account, something that requires an e-mail. If you'd like your students to be able to work together on a map without having to register for a Google Account, Linda Dierks suggests ScribbleMaps.

As an alternate way to have students collaborate on maps, I've been using Scribble Maps (http://scribblemaps.com). It gives many of the same features Google Maps can without having to set up forms. You can save the map you create to a unique URL and password (still no ID needed) and share it with others. They can save changes as long as they have the correct URL and password.

Thanks for the idea Linda.

Collaborative Maps

Ever sit around playing with a particular web tool and say, "This is great, but there's got to be a way to...(insert your idea here)." This particular question has been rolling around in my head regarding Google Maps. I LOVE Google Maps, but have been frustrated that I haven't found an easy way to create maps collaboratively. I know I can share Google Docs and have multiple people working on the same document, presentation, or spreadsheet, so why can't I do the same with maps? I was ready to write a blog post today pleading with Google to add a SHARE button to Google Maps when I was reminded of a tool that Andy Losik shared with me last spring.

There IS a way for my students contribute placemarks to a Google Map. A way that doesn't require them to use my login, or even have a Google account. Here's what you do:

1. Create a Google Form - Students will use this form to enter their placemark information. This will put their information into a Google Spreadsheet. No login required. They just need a link to the form.
2. Use Map A List (www.mapalist.com) to auto-generate a Google Map that's linked to your spreadsheet.

Details
To set up your Google Form, you need to know that Map A List determines location using the following fields:

• Address 1
• Address 2
• City
• State
• Zip
• Country
• Latitude*
• Longitude*

*Latitude & Longitude information supersedes address information.

You'll then want to add three additional fields for the placemark information.

• Title - What appears for the title of the placemark.
• Additional Info - What appears as the text in the popup window. This field will also accept HTML code. So any code you can copy & paste into Google Maps will work here too.
• Placemark Symbol Identifier (optional) - This could be a multiple choice item in that your students use to select what type of placemark they want.

Here's a sample Google Form I created. Feel free to add your data to it.

Once your form is done and you've started collecting information, go to Map A List and sign-up for an account. After that, you'll need to give Map A List authorization to access your Google Spreadsheet. Once that is done you can start creating your map. It's a simple step by step process.

Select the spreadsheet that contains your map data.



Match the fields in your spreadsheet to the ones that Map A List uses to create your placemarks.



Once that is done, Map A List will check to see how many locations it can find based on the information in your spreadsheet. It does a surprisingly good job of determining locations even with incomplete information.

If you added a field that determines what type of placemark to use, the advanced feature on the next step is where you enter that information.



The last step is where you save your map and set a few final options. If you want to be able to send a link to your map to others or embed it on your web page or blog, you'll need to make it public.

Here's a link to the Google Map I created with my form. If you added data to the form, it may take a while to appear on the map. I set mine to update automatically, but noticed that sometimes I need to go in to Map A List and tell it to update the map manually if I want to see new data added the spreadsheet.

Classroom Applications
Students can participate in this type of collaborative map by...

• Mapping Birthplaces. It could be their own, or someone else's. Our 5th grade is working on immigrant reports right now. This would be a fun way to share their information.
• Historical Places. Students could work together on a class project locating and posting information about historical places around their state or country.
• What's The Weather Today? Classes from several different schools could pick a day and share the weather. They could even embed a picture of what it looks like outside.
• Breakfast Around the World. The form could be shared with as many people as possible to find out what people around the world eat for breakfast. Hmmmm. This idea sounds familiar.
• I'm sure you can think of other ideas...

This is great, but there's got to be a way to...
Add lines? Highlight regions? Draw shapes? I haven't figured these out yet. If you have any ideas please share them.

By the way Google, this does not let you off the hook. I'd still like to see a SHARE button on Google Maps.

Summer Reflections 2

Fun With Time-Lapse

In addition to digging into Google Maps, this summer was also an opportunity to explore the world of photography. I haven't owned an SLR camera since my old 35mm Canon T70 died back in the early 90's. Things have changed a lot and my new Nikon D5000 has some pretty impressive features. For those you hardcore photographers this is just an "entry level DSLR", but for me it was a major step up from the point & shoots I've been using up to now.

One feature I'm really enjoying is the Interval Timer feature. This allows me to set the camera to take a certain number of pictures at a specific time interval. This is a great way to capture a series of images that can be combined either inside the camera or using video editing software like iMovie, Movie Maker. For example, I was able to capture time-lapse images of storm clouds moving over Lake Powell this summer. To create the sequences below, I put the camera on a tripod and set it to take one picture every 10 seconds for about 60 frames.



The ability to shoot time-lapse has lots of creative possibilities as well as some science applications too. Things to remember:

• Make sure the camera doesn't move while you're capturing images. After seeing the results of my first few attempts, I learned that it was better to set the tripod on the ground because the houseboat moves.
• Don't use the maximum resolution of your camera. You don't need a 3000 x 4000 pixel image if you're making a video. Besides, you'll fit a lot more on your memory card if you scale it back a little. The best HD video resolution is only 1920 X 1080.
• Make sure you have a full battery charge or, if you have an AC adapter, plug your camera into a power source. A lot of time can be wasted if your camera dies during your interval shoot.
• Experiment & have fun. Just like the Hokey Pokey - "That's what it's all about."

Summer Reflections

Many of you start a new school year today. In just a moment students will be arriving, anxiously waiting for the pearls of wisdom you choose to bestow upon them. Like me, many of you are probably wondering how summer went by so fast. It seems so close, yet as you frantically put those finishing touches on your classroom, it also seems infinitely far away. It wasn't that long ago, I think it was July, that I was in Alaska exploring Denali National Park and cruising the Inside Passage. When I get stressed about everything on my "to-do" list it helps to go back and re-live that adventure. It puts me back in my "happy place".

Because I consider myself a bit of a techie, I used the trip as an opportunity to dig in and really get familiar with Google Maps. Below is my Alaska Adventure.


View Alaska Adventure in a larger map

Creating a Google Map is a wonderful way to combine stories, pictures, and video from your vacation. I was able to arrange events in order, map my travel route, and place pictures and videos in their proper place on the map. It's like an interactive travelogue. And sharing my travel story is as simple as copying and pasting a link into an e-mail (or blogpost).

When editing a "story" events can be rearranged by simply dragging them up and down the list on the right side of your screen. Lines can be added to show travel routes. One feature I really liked was Google Maps ability to make lines follow known roads or highways. (I don't even think you can do this in Google Earth.)



I had no problem adding photos I had posted to my Flickr account. In the "rich text" editor you just click on image button and paste the URL.



Google Maps will also accept some embed code. Using the "Edit HTML" feature, I was able to copy and paste code to embed video clips I posted to YouTube. Since Google owns YouTube it makes sense that this would work. I did not have any luck trying to embed something from Voicethread however. It may take some experimenting to see what it will and will not accept.



As you can imagine there are lots of possibilities for using Google Maps in the classroom. Maps are a great way for students to grasp large amounts of data in a way that isn't overwhelming. Here's one that shows recent earthquakes around the world (earthquakes.tafoni.net). Do you think your students could use this information to locate the boundaries of tectonic plates? If your class is looking at current events, the LA Times has one with updated info about the Station Fire.

You can also get students involved in creating Google Maps. In an earlier post I showed a "Breakfast Around the World" map created with data collected from our 3rd graders. Colette Cassinelli created a project she uses with her students called "Postcard Geography". I can see our 5th grade teachers doing something similar for combining information from students' state reports. (Colette also has some great Google Map links on her wiki.)

One hurdle you need jump when using maps with students is that Google Maps is not part of Google Apps for Education. So in order for students to edit a map or create their own, they need to register with Google and create their own Google account, or use one created by their teacher. Otherwise the teacher will have to take work submitted by students and post it to Google themselves. (That's what I've done.) Hopefully this is something Google will add to Apps for Ed in the future.

Enjoy playing with Google Maps and if the new school year gets a little overwhelming, take a time out, think back to summer and map your summer memories. I think I 'm going back and look at some Alaska pictures right now.

Listening with Their Eyes

"These kids just don't listen!"

You may not have said it out loud, but you know you've thought it. Sometimes it seems like the words we say just bounce right off. You might as well be talking to a wall.

It's true. There are times when kids don't hear a word we say, but that doesn't mean they're not listening. Maybe they're listening with their eyes.

In a recent Sunday sermon, this quote was shared:

I'd rather see a sermon than hear one any day;
I'd rather one should walk with me than merely tell the way.
The eye's a better pupil and more willing than the ear,
Fine counsel is confusing, but example's always clear;
And the best of all the preachers are the men who live their creeds,
For to see good put in action is what everybody needs.

I soon can learn to do it if you'll let me see it done;
I can watch your hands in action, but your tongue too fast may run.
And the lecture you deliver may be very wise and true,
But I'd rather get my lessons by observing what you do;
For I might misunderstand you and the high advise you give,
But there's no misunderstanding how you act and how you live.

excerpt from 'Sermons We See' by Edgar Guest

When you stand in front of your students what are you telling them? On those rare times they they do listen with their ears, does the message they hear conflict with the one they receive with their eyes?

Like it or not, when they're looking at us they're learning more than just the curriculum. The lessons they learn with their eyes are lessons in character. These lessons are taught continuously and unconsciously - both in and outside the classroom.

Our actions can be a powerful teaching tool when we SHOW our students what to do rather than just telling them. Think about it. When we use our words to say, "This is important." Do our deeds back it up?

Look at the way we teach information literacy and digital citizenship. When we tell kids to go find information on the Internet, do we also model good search techniques in class? Do we demonstrate how to evaluate information for accuracy or bias? We tell them to be sure to respect copyright and to cite ALL their resources for papers & projects, but do we take the time to do the same for our presentations & lectures?

We emphasize good digital citizenship and encourage students to protect themselves online. We warn them that what they post can come back to hurt them later if they are not careful, but do we also exercise those same practices ourselves? Would you want your students to see your Facebook or MySpace page? How would you feel if they started following you on Twitter?

"I'm no role model" - Charles Barkley

Maybe Charles Barkley isn't, but we are. We chose to be when we made the choice to become teachers - I think Teach42 would back me up on this. The students in our room are watching to see if the words they hear from us are more than just hype.

Now I've made a personal choice not to "friend" my students on Facebook and as far as I know none follow me on Twitter, but if by chance one of them happens to see my profile or read my tweets, there's nothing there that should cause me to feel shame or regret. I believe we need to be role models to our students in the way we act in public and online. This doesn't mean we have to be perfect - kids see through that facade right away. It just means we have to be real and make sure that our words and our actions are not sending mixed messages.

And all travelers can witness that the best of guides today
Is not the one who tells them, but the one who shows the way

The Final Frontier

Here's another one of those serendipity moments.

A weekend fishing trip up to the Owens Valley yielded an unexpected surprise. If you've ever driven up US 395 you may have noticed those large radio telescopes off to the east between Big Pine & Bishop, CA. For years I've wondered about those and have always wanted to get a closer look and learn more about them. What I never knew, is that 13 miles east of there, tucked up in the hills is another similar array.

Here's the serendipitous part - the day we picked to fish the Owens River just happened to be the same day that CARMA (The Combined Array for Research in Millimeter wave Astronomy) was holding their annual Open House. We followed the signs along the highway, headed east on highway 168 past the big dishes in the valley up into the White Mountains, and found the observatory site and it's 23 "telescopes".



Upon arriving we were greeted by Dr. Mark Hodges from Caltech who started the tour by sharing some information about the array and some of the work being done there. While not as big as the 130 ft dishes in the valley, what these telescopes lack in size, they make up in quantity and precision. The 10 and 3.5 meter dishes here are practically perfect parabolas - the margin of error is about the width of a human hair. By using an array of telescopes they are effectively able to get the same information that could be obtained by a much larger dish. As we toured the facility, Douglas, one of the engineers explained how the racks of computers he designed process terabytes of information received from the array, filter out the noise, and combine it into one "image".

Why take a picture with radio waves?
After munching on free hot dogs provided by the CARMA staff, Eric, one of several astrophysicists on site, explained that while the Hubble Telescope provides stunning visual images, it doesn't give us the whole picture. Radio waves provide much more information about distant stars & galaxies and help scientists determine not just what they look like, but also identify the molecules that make up these distant objects. Also, because radio waves are not affected by visible light, these telescopes can be used 24 hours a day.

What type of research is being done here?
When I asked Eric about his project, he shared that he currently has the 3.5 meter array pointed at a cluster of galaxies and hopes to use the information he gathers to prove the existence of dark matter.

The CARMA array is funded by the National Science Foundation and is a jointly operated by Caltech, UC Berkeley, the University of Illinois, the University of Maryland, and the University of Chicago. Every 6 months, the NSF accepts research proposals and determines which ones get time to use the array. The allocation of time is a valuable thing because a single "picture" taken by the array can take take several hours. Douglas, one of the CARMA engineers, explained that to get one image, an array of telescopes captures lines of information as the Earth rotates. After about 8 hours these lines create a complete circle and the computers get to work to process the image. "It's like the world's slowest digital camera."

That's me standing next to one of the 10 meter telescopes.

A Simple Solution?

Back in November 2007 I posted a "Not So Simple Solution" demonstrating a fairly complicated way to take projects created in Microsoft PhotoStory3 and make them viewable on Macs.

While brainstorming a way to share our 3rd grade Animal Riddles online (thanks Jennifer Gingerich for the project idea) I tried uploading the wmv files created by PhotoStory directly into Voicethread - AND IT WORKED!

Now we can not only share our students' PhotoStory projects, but putting them on Voicethread allows us the option to let others comment back. Nice!

Below is an example. (Until I get an OK from the teacher I've turned off commenting.)
