Way to go iClicker!

In an earlier posting I discussed some less than optimal packaging with a recent order of iClickers. We’re very happy with the clickers themselves, btw (which is also in the earlier posting). A glitch with my blog comment notifications caused a great response from the Director of iClicker to sit in moderation for quite a while. My apologies for that. It’s since been fixed.

I wanted to highlight Renee’s response here. Since the posting, I was also contacted by one of the iClicker creators about an idea I’d posted on a list serve about making analyzing data gathered via iClickers easier. We had a great conversation, and they are exploring adding some additional features to make analysis more seamless.

Thanks for being so responsive and committed to sustainability! I’m impressed.

Mars Phoenix converts a Twitter skeptic

I’ve been very skeptical about educational uses of Twitter, but I have to admit that a little lander on Mars has changed my mind. This fall I’m teaching a course for non-science majors that centers around exploring the physics, chemistry, and geology surrounding a manned space mission to Mars. When I found out the Mars Phoenix Lander was providing mission updates via Twitter, I decided to take the plunge.

The lander (through a ghost writer) sends out tweets, sometimes several times a day, with mission updates which I follow through Twitterific (screen shot below).

Twitter Mars

One of the objectives for the course is for students to get a real sense of the scale, terrain, and environment of Mars. That’s not something that gets accomplished through a single lesson. Having the students subscribe via Twitterific or text message updates (I haven’t sprung for the extra $ to get into that) seems like a great, subversive way, to weave Mars into the daily lives of students. Phoenix “tweets” have often led me on a curious quest for more info, and I’m hoping it will do the same for students.

I was psyched to learn that the mission had been extended (through a tweet, of course) to the end of September, so I can use this for at least part of the upcoming semester. Here’s just one example (of many) of a great pointer from Phoenix, which can be used to address common misconceptions about the cause of the seasons.

Oh yeah, here’s a link to the famous Private Universe video showing interviews with Harvard grads that demonstrates just how tenacious this misconception can be.

If Twitter can help, I’m in!

Concept Map Software Demo – CmapTools

CMapTools is concept map software which is available free for educational use. I created a quick demo of some of the main features. I especially like the support for mulitmedia objects.

Oops! See this 60 sec correction / tip for saving space in your concept map.

Of course, there are many academic uses, but the above superhero example is kind of a fun intro (see more detailed, finished super hero map here). For example, the Science Education Resource Center (SERC) at Carleton College has some great information on using concept mapping in the geosciences.

Sustainable Packaging?

I know it’s been a long time, but I’m hoping to get back in the blogging groove. I have a list of blog topics in a google doc that I’m hoping will sustain a more regular blog presence. I’ve moved my site over to a new host.  I’m redirecting automatically for now, but please update your bookmarks.

I’ve mentioned in previous posts that we’ve been exploring clicker technology in class to promote class discussion (especially around controversial topics), predicting the results of a demo, etc. . We recently received a shipment of 60 clickers, and I was distraught over the packaging. Check it out. Each clicker was individually wrapped in the kind of packaging that leaves one’s fingers bruised and bloodied, and the amount of waste is pretty striking. Below is a pic of the packaging vs. what was inside.

packagingclickers

We’re in conversations now with the vendor now to check into alternatives. They may be under the assumption that we’re like many schools where clickers are sold in the bookstore. Instead, we’ve purchased several departmental sets for sharing. The six teacher clickers came with a more reasonable amount of packaging, so it has to be possible to scale back on the waste. We’ve been very pleased with the iClicker brand, but if you decide to go this route, please join in and ask about alternative packaging before they ship.

Some things the iClickers don’t do that we’re trying to find solutions for:

1. Data Formatting – We have a couple of professors interested in analyzing data gathered in class with statistical packages like SPSS. The session data is stored in spreadsheets, but there’s a lot of manual cleanup needed before the stats are run. It shouldn’t be too hard to automate the clean-up process.

2. Limited Choices – A-E works fine for many questions, but if you’re asking students about presidential candidates, important political issues, etc.., 5 choices can be very limiting. We knew that going in, but it would be great if there were a simple alternative. I asked the tech guy at iClicker if they’ve explored hooking into devices with more buttons or allowing a double click to expand choices (like AA, BB, etc.). They haven’t done anything with this yet, but the code is open source, so I’m going to poke around and see what it would take to add this expanded choice mode.

3. Mapping Choices – The flexibility of the software is great. You can pose questions / scenarios in presentation software, ChemDraw, Google Earth, etc.. Because the question is captured as an image, you have to go back and map choice A to Obama, B to Clinton, C to Edwards, etc.. It’s okay if you’re just using the questions as a discussion starter but makes looking at trends in student opinions more difficult.

Brief Furman Tour in Google Earth from Geocoded photos

Man, Furman campus is beautiful in the spring. I’ve been experimenting with a handheld device (ipaq 6900 series) that EES professor Suresh Muthukrishnan has been using in class. It has built-in GPS, so I went out and snapped a few pictures this morning. It was great to have an excuse to walk around campus in the cool air. The latitude and longitude are geocoded into the picture when the GPS is on, so I wanted to see how easy it would be to create a google earth file (kml or kmz) to show a virtual tour of where I’d been. It looks like Google Earth Pro can rip the geocoding information from the picture and create the file, but I can’t spring for the pro version yet.

Instead I used a program called RoboGeo to create the kml file. It looks like the program is very useful if you don’t have a GPS built into your camera as well. It did a good job creating a path from a series of photos. Check out the tour in Google Earth.

furman_tour_image

In the ‘Places’ window of Google Earth you have to open the ‘routes’ folder and click ‘path’. You can see that it just connects the dots and shows me swimming or boating out to the bell tower 🙂

The trial version throws an error into the latitude and longitude value, so I had to override those manually. That’s why the images are attached where the object is rather than where I was standing when I took the picture. The full version will geocode from the photographer’s location with no kml editing necessary.

I think you’ll also see why I did poorly in photography class.

Learning in Retirement Blog Class

Yesterday I taught a FULIR (Furman University Learning In Retirement) class on blogging as part of Dr. Lipscomb’s What’s New in Technology Series. I’m really enjoying the opportunity to get back in the classroom, and this was a great group of folks – friendly and very curious, especially with regards to how this technology fit into the big picture. The initial discussion was fostered with some iClicker questions about experience with blogs and familiarity with the term ‘Web2.0’. After a quick overview, we jumped into creating our own blogs.

The time I spent on Friday creating WordPress accounts (wordpress.com) for each participant was worth it. We quickly started creating posts, and I think everyone enjoyed swapping out themes.

theme

Sample WordPress Theme

I’d like to see WordPress simplify adding pictures to a post. What if by inserting a photo into a post, it was uploaded behind the scenes, instead of having to upload, send to editor, etc..? We got through it, but the challenges highlighted the counter-intuitive user interface.

I think a decent portion of the class may keep blogging, based on the questions I was getting after class. Several wanted to know more about feedreaders, so they could consolidate the blogs they have been following.

A couple of things to do differently next time:

1. Track down some mice for the laptops. The trackpad was a significant barrier at times.

2. Provide more detailed, step-by-step instructions for adding / editing a post, and especially adding an image.

A couple of things to keep:

1. The clickers. This helped get a quick, anonymous gauge of experience level.

2. Directions on how to get to the admin panel. Many of the themes either make this link hard to find or remove it altogether, so having this in the handout really helped.

I really enjoyed this and might propose some classes for the spring!

One person commented as they left that they would explore this more the next time they couldn’t sleep. My blog started one morning when I was tossing and turning. I wonder how many blogs have started during a bout of insomnia??

Upstate Schools Consortium Presentation and Clickers

On Friday I presented at a meeting of the Upstate Schools Consortium which met at Furman University. I got to meet with a great group of talented and enthusiastic K-12 educators from across the upstate. It was a lot of fun!

clickers

I talked about our recent and early investigation into clicker technology. We’re piloting these in a handful of classrooms to determine if they’re a good fit and developing best practices. I’ve reviewed a good bit of the research, and it seems like clickers are most effective when they are used to support a constructivist learning environment which makes good sense. A great bibliography of the research is available from Vanderbilt University. If the technology is only going to be used to deliver fairly low-level content questions and not going to be used to modify instruction or engage the student, then I’m guessing we’ll find it’s not worth the investment. I’ve used them in several sessions and feel my initial skepticism waning.

Here’s a link to the question report that was generated from our discussion. Just click on the session summary to see the responses. Each session is actually split in two, so session 1 and 2 are the interaction with the first group and so on. For some reason, the second half of the session with the last group wasn’t recorded.

I split the sessions because there seems to be a bug in iClicker (at least on my machine) where if you add to an existing session, rather than starting a new one, the screen capture breaks.

* The question about Saddam Hussein was to start a very mini discussion about potential advantages of the anonymity that the clickers provide. I wish we had more time to discuss.

* The question about the gorilla required some intro explanation not on the slide. I described the Harvard study in which folks were asked to count the number of basketball passes between two individuals. During the video a woman with an umbrella or a person in a gorilla suit walks through the middle of the scene. 54% of participants reported never seeing the gorilla, so I asked if this intense focus would be a plus or minus in a life or death survival situation. In sessions where there was time, they discussed and recast their votes (Mazur-type of model with clickers).

* The Google Earth Question revolved around the spread of avian flu and asked participants to predict where the early outbreaks occurred (answer C: Southern Asia). The circled regions aren’t visible in the iClicker report, but were visible to participants.

* Oh yeah, the answer to the state insect question is A (Carolina Mantid). This was pretty obscure, but most folks knew it! I sure didn’t. I was hoping to demonstrate that simple content questions weren’t as fun or interactive as the gorilla / discussion type, but this generated a good bit of buzz as well (pun intended ;-)).

I’ll be updating the blog with our iClicker pilot experience. Here’s a link to the session handout. Please comment with your clicker experiences and thoughts in the comments here. We didn’t have enough time to talk, so it would be fun to continue the discussion here.

Google Earth and Running

running
mapmyrun.com is a really cool website for runners. It allows you to map your run using Google Maps / Google Pedometer technology, determine distance , share your route with others, and save the route with your profile. You can also put in your time, height, weight, etc.., and it will calculate your pace and calories burned.

If you’re running with a GPS unit, you can upload the data to mapmyrun, and it will automagically map your route. I don’t run with a GPS, so I haven’t tested it yet, but that would save some time.

Another nice feature is that the site will automatically create a kmz file, so if you have Google Earth and open this file, your route is mapped in Google Earth. Here’s my route from Furman to the North Greenville YMCA in mapmyrun and the kmz file for Google Earth.

And to think, I used to get in my car and use the odometer to gauge a route. How early 2000! 😉 Now if they could only add a feature that would map the location of ankle biting little dogs, and it would be perfect!

Great Google Earth Feature – Time Animation

On the Google Earth Blog, Frank Taylor lists the top ten Google Earth time animations for 2006. Time animations were added in Google Earth 4 and are a great way to view data that changes over time, for example animal and human cases of avian flu (Declan Butler’s blog). Authors simply add a time span element to data in kml files, like so, and Google Earth renders a time slider bar in the user interface.

<TimeSpan id=”ID”>
<begin>begin date here </begin>
<end>end date here</end>
</TimeSpan>

The time slider is highlighted in a screen shot of the avian flu map below.

google earth

There are some Google Earth software limitations that were apparent when viewing Hurricane Katrina data. I wished I could have incremented the “animation” in hours rather than days. There are some great suggestions for improvement on Stefan Geens’ Ogle Earth Blog, so I won’t rehash them here. This functionality is a great addition to GE!

Wii and Physics?

Tim Lauer of Lewis Elementary School points to an interesting use of Darwiin Remote Software and the Nintendo Wii remote to run a Roomba (a robot which will vacuum your house). I don’t have a Nintendo Wii game, but if Darwiin will capture 3D acceleration from the Wii game remote, it shouldn’t be too difficult to determine force information from the remote. So if someone is playing Wii baseball for example, it should be easy to capture the force of their swing. Perhaps students could experiment with different variables to increase the force of the swing and determine the impact on the distance the batted ball travels. Does the game show the force of the swing already?

In my physics classes we used the Vernier accelerometers to capture 3-dimensional acceleration on different amusement park rides. Although the experience turned me green, we got exceptional data (see image and graph below). I wonder if using a combination of a Wii remote, Bluetooth, and some sort of handheld device if the same sort of data could be gathered on the ride? It still doesn’t solve my motion sickness, but maybe it would save a few bucks and be fun to try.
