ELTU Unconference

breakout area 2 for ELTU

We’re about a week and a half away from the fourth annual Exploring Learning Technologies Unconference (ELTU4).  This year, we’ve moved the event to the start of the academic year because the spring was becoming crowded with other conferences and events.  So, on Friday, October 14, we meet again from 9am to 1:30pm to unconference.

What is an unconference?  There are lots of different variations, from Open Space to various camps (FooCamp, Barcamp, Mashup Camp, etc. — see Wikipedia for more.)  Our variant resembles a traditional conference in may ways — there are meeting areas for different breakout sessions that begin every hour —  but the biggest difference is that none of the content is set in advance of the meeting.

We spend the first half hour with introductions and generating session topics.  From there, the group negotiates which topics go in which time slots and we begin.  Being a technology-themed unconference, we use some technology to facilitate this process: we project the session grid on screens around the room so everyone can see and participate in the process.  We also set up a wiki in advance with one page that lists the schedule and links to one page per session so someone in each session can take notes.  (Visit http://go.osu.edu/eltu to see the wikis from the last three unconferences.)

Once organized, the unconference runs a lot like a regular conference, though participants are encouraged to move between sessions as a way of cross-pollinating the various discussions.  In fact, we have traditionally hosted the unconference in one big open space or computer lab in order to facilitate this movement.

The beauty of the process is that, if everything works as intended, the discussions are all appealing to those in attendance because they were generated only by those in attendance (instead of presenters who submitted an abstract months in advance and then failed to attend the conference.)

The effect is intentionally a bit like the hallway conversations you have at a traditional conference — when you actually get to talk to someone with similar interests to you instead of just watching a speaker read their PowerPoint slides.  By attracting interesting people from across campus and throughout Ohio, the discussion at the unconference is always a good one.

I’d recommend the format to any organization interested in hosting a stimulating conversation.  I’d also welcome you to our next unconference on Friday, October 14 from 9am to 1:30pm.  Details are available at http://go.osu.edu/eltu and registration is available (and free!) at http://eltu4.crowdvine.com.

Genetics for Kids

test tubes

Over the past ten or twenty years, the news media has become saturated with stories about genetics.  But do you really understand how genes interact?  A new genetics simulation being developed at Ohio State can help.

The simulation begins with a series of cartoon faces from which the user can choose to populate the gene pool for the next generation.  (The term “parents” is used, but more than two can be selected.)  This process can be repeated several times to create successive generations of cartoon faces.

Over 50 “genes” are incorporated into the faces (affecting everything from the dimensions of the head and other features to how asymmetrical the face is and whether the eyes follow your mouse or not) and the genes of the “parents” interact to produce the subsequent generation.  You can also adjust the amount of mutation, which leads to a wider (or narrower) variety of offspring.

Another interesting feature is the ability to view genotypes.  This allows you to view a graph under each offspring representing which genes come from which parent.  You can also choose two faces and drag them to the Gene Exam Room to view to what degree each gene is represented in each face.  This also allows you to see the effect of each individual gene.  You can even increase or decrease the representation of each gene to see how it changes each face.

What can you (or your students) do with this simulation?  Imagine the faces are puppies and you want to develop a new breed that is cute (or whatever other trait you’re interested in.)  This simulation clearly demonstrates how breeders (of animals, plants, etc.) select for certain traits and refine them over generations.

Or imagine the choices you  make in the simulation are not choices, but represent the effects of the environment.  For example, say the Sun grows dim giving people with big eyes that can see in low light an advantage over people with small eyes.  This advantage results in a higher percentage of offspring surviving and a wider representation in the gene pool.  What effect would this have after several generations?

Think of how much richer students’ discussions of designer pets and natural disasters will be after they have “experienced” the process instead of just reading about it.  In addition to genetics, this simulation can also stimulate interest in probability (how likely are offspring to have certain characteristics), design (ideas behind evolutionary design were the impetus for the interface), as well as all of the social issues behind decisions we are now able to make regarding genetics.

In terms of ESL teaching, I think giving students something interesting to do and then having them talk or write about it is a great way to get them to practice English.  This genetics simulation is simple but interesting enough that it could generate lots of interesting ideas for students to talk about.

Kinect-Based IWB

Ever since a $3000 bounty was placed on cracking open Microsoft’s fab new gaming hardware, the motion-sensing Kinect for Xbox, hackers and tinkerers have been putting the open-source drivers to lots of interesting uses on platforms that Microsoft never envisioned.  I’ve written about interesting Kinect hacks before (and before that,) and I’ve written about my experience with the Wii-based $50 Interactive Whiteboard (IWB,) but I haven’t seen a fully-developed Kinect-based Interactive Whiteboard.

Perhaps an Interactive Whiteboard is too narrow a description.  Many of the pieces are in place (see below) to interface with a computer using Kinect.  So, as with the Wii-based IWB, any application you can use on your computer can be controlled by this hardware.  If you connect your computer to a projector, you essentially have an Interactive Whiteboard.

Is the Kinect-based experience different from a Wii-based IWB or a Smartboard?  Almost certainly.  There would be no need to touch the screen at all, but rather to gesture in front of the Kinect to interact with the projection on the screen.  Would this be an improvement?  I’m not sure.  A touch-based IWB is more analogous to traditional whiteboard that uses markers and an eraser.  So, the touchless experience would be quite different.  I need to try it myself to really wrap my head around the opportunities that this motion-sensing interface offers.

I’m not sure if anyone here at Ohio State is working with Kinect as an interface for non-Xbox applications.  But I do know that the Digital Union has a Kinect which could probably be used to see if and how things work.  If anyone else is interested in trying to pull this together, drop me a line or leave a comment.

Computer Games in ESL

burning pac man

Computer games are a medium that has become as popular as Hollywood movies.  It’s not uncommon for teachers to show movies in class, but how can games be incorporated?  This post will discuss these questions and will serve as the handout to my session at the Ohio TESOL Technology Fair 2010.

Games as a source of English

MMORPGs and other complex, multiplayer games can provide a rich source of English (or many other languages) in which students can choose to immerse themselves.  Also, because these games are almost impossible to solve without teamwork, there are typically

World of Warcraft (WoW) – The granddaddy of all MMORPGs and by far the biggest.  Players create avatars that go on quests and have adventures.   In addition to finding potentially complex communication tasks with other players during the game, the WoW wiki is the second largest wiki on the internet after Wikipedia.  This is also potentially a good source of target language input.

Second Life – Though not exactly a game, per se, Second Life is an online 3D virtual world through which players’ avatars can navigate.  There has been much educational interest in Second Life which means there are several “islands” dedicated to language practice for users to explore.

Analysis of Simulations

Distinguishing between games, serious games and simulations is not as important as how we can use them.  Playing a simulation may not be entirely satisfying because a totally accurate simulation of any complex system is extremely difficult to create.  But this creates an opportunity for students to try them and then critique them.  There are lots of examples listed on Historical Simulations.org.  Some of my favorites are below.

Budget Hero – Where would you increase and / or decrease the federal budget and what ramifications would each decision have on the future?  Lots of information in a very accessible format.

Energyville – See if you can meet the energy needs of a city of almost 6 million people.  Do you think cutting all fossil fuels immediately is the answer?  Not in this simulation.  Does knowing that it was created by Chevron make you question anything about this simulation?  Lots to discuss here.

McDonald’s Video Game – What decisions would you make (have to make?) to keep your franchise humming.  Would you cut corners?  What effects would this have?  And, as with Energyville, above, is this an unbiased view or is there an underlying message in this game?

Group Problem Solving

Even the simplest games can generate complex discussion when played in pairs or as a group.  Two students working at one computer need to negotiate everything starting from who gets to use the mouse.  If you have access to an interactive whiteboard, a larger group can work together to play the game or solve the puzzle much more comfortably.

Samorost 2 – This is a visually compelling game that, at first, does not seem to have a point.  During a brief cartoon introduction, a dog is kidnapped from a tiny planet by space aliens and the protagonist begins his pursuit.  Now what?  By clicking on various items on the screen they can be manipulated.  Puzzles can be solved by finding the appropriate series of manipulations.  I’ve had a half-dozen students working on these puzzles on an interactive whiteboard.  I was worried because when working alone on my desktop, I found the puzzles to be quite challenging and I almost gave up on more than one occasion.  But the power of the group was amazing to see as the students moved quickly through several levels, working together and suggesting new ideas to each other as they went.

Grow Cube – I’ve been intrigued by this game since the first time I discovered it.  It is a puzzle in which the player ten turns to select from ten actions that can be performed on a cube.  Each one has a cute animation that interacts with the others.  Most importantly, some actions require several turns to fully develop.  Others must be performed sequentially to work properly (spoiler alert: place the pot on the cube before lighting the fire or the fire will grow too hot and crack the pot.)  The puzzle typically requires one or two attempts to get a feel for the game before players can really begin to notice the effects that each action has on the others.  Even if the puzzle can not be solved, there is a complete walkthrough available for help.  But do yourself a favor and don’t peek until you’ve given it a few tries.

Other Tips & Suggestions

Some of the most complex games available will also be the most expensive.  Even if that hurdle is overcome (possibly by purchasing older versions, for example), there may be a variety of reasons that prohibit the installation of World of Warcraft in the local computer lab (“You want to play games?!?”).  Fortunately there are a number of online games which are freely available and only require an internet connection to play.  Of course, if you routinely battle a firewall for internet access, you may want to test whether you can access them on the computers you intend to use before you plan to use them.

Ask what your students are playing and see if those games might provide a jumping off point.  Are they addicted to Farmville on Facebook?  Bejeweled?  Can they analyze the game critically?  Can they teach someone else the strategy involved?

Most games have wikis which describe all of the parts of the game as well as strategies that can be used to win.  Is there an undocumented way to win?  Have students contribute their ideas to the wiki.

Exploring Learning Technologies Unconference (ELTU) 2

ELTU logo

The second annual (well, second ever) Exploring Learning Technologies Unconference is next week, Friday, May 21 from 9-1:30pm in the Science and Engineering Library at The Ohio State University.  ELTU2 is open to anyone in Ohio who is interested in the intersection between education and technology.

What is an unconference?  Think of it as conference 2.0.  It will have the basic structure of a conference (3 rounds of 48-minute breakout sessions) but the content of the sessions will be decided by the participants on the day of the unconference.  And because all of the sessions will be in one place, it will be very easy (in fact, participants are encouraged) to move between the different discussions, thereby cross-polinating them.

Last year this worked very, very well.  There were lots of great discussions between an interesting cross section of people at Ohio State.  This year, we’re opening it up to the whole state and already have participants registered from almost every corner.

Will you be in Columbus, Ohio on Friday the 21st?  Join us.  For more information, visit the unconference website tr.im/eltu2 or register at eltu2.crowdvine.com.

Image Size and Resolution

over stretched image

Think this image looks good? Click on it to see it actual size. Yikes!

I made a presentation at Ohio TESOL last week about how to make better PowerPoint presentations.  I’m going to add the audio to my slides by the end of this week (currently, you can only view the original slides sans audio).

Overall, the presentation was very well received.  In fact, I even inspired some people to overcome their fear and give PowerPoint a try.  One such brave soul emailed me the following question about blurry images, which I think is worth sharing here.  It’s a problem that many beginners face when adding images to PowerPoint presentations as well as print documents.  You won’t be an expert until you can fix it.  My response follows.

I loved your presentation last week on PowerPoint.  Being technically challenged, pp has never been at the top of my list to try.  But, after listening to you last Friday, I have put together a small presentation for a listening and speaking one class.  My question is…After I paste and stretch photos from Flicker, they are blurry.  I realize it is probably a simple click, but I cannot find it.  Please help!

I’m glad you enjoyed my presentation and I’m glad you’re diving in  and trying things out in PowerPoint.  I think this is a really good way to learn this technology.

image stretched 900%

Stretching an image to 900% of its original size will result in a blurry or pixelated image.

The issue you’re dealing with is a common one.  It has to do with the size and resolution of the original image you’re trying to add to your presentation.  When you are in PowerPoint, double-click on the image you’re working with to pull up the “Format Picture” menu.  Choose the “Size” tab at the top to see if you’ve stretched your image past it’s original size.  If the height or width under “Scale” is more than 100%, you will probably experience some blurriness or you will start to see all of the pixels that make up the image.  (To really see this, try using a really small image from a website and stretching it to fill your entire slide.  It will get really, really blurry and pixely.)

flickr picture

Click on "all sizes" to find larger versions of images in Flickr.

So, that’s the problem, but what’s the solution?  Well, you need to start with larger original images.  Once you find an image in Flickr, you will see an “ALL SIZES” button right under the title of the picture.  This will take you to the original picture and often give you several different size options.  By choosing the original, you can usually find a version large enough that you will be able to stretch it to fill your slide.  I suggest you double-check after you stretch it though (double-click again to pull up the Format Picture menu) because if it’s more than about 110% of the original size, your picture may look stretched when projected onto a screen even if you don’t notice any problems on your computer.

Something else to consider is the file size of the picture you use.  If you just need a small picture, try to avoid using the largest size.  Using larger pictures increases the size of the file for your final presentation.  While finding room on a hard drive usually isn’t a problem for new computers, on some machines PowerPoint can get bogged down and run slowly if many large photos have to be loaded for every slide.  So, if you only need a little picture in the corner, try using a smaller size image.

I hope that’s pretty clear.  Give it a try and let me know if you’re still having trouble.  Incidentally, I hope to upload an updated version of my presentation complete with audio in the next couple of days.  Watch for it here: http://www.slideshare.net/eslchill

More Interactive Whiteboards, Please

Ohio TESOL 2009 was 10/31-11/1 in Columbus, Ohio.

Ohio TESOL 2009 was 10/31-11/1 in Columbus, Ohio.

Ivan and I presented the $50 Interactive Whiteboard to a standing-room-only audience of other teachers of English to speakers of other languages at Ohio TESOL this weekend.  Not only have I now distributed all five from my original Ohio TESOL grant, but I’ve also got over a dozen people signed up for test drives.  Looks like I need to write another grant.

If you’re reading this and you’re a member of Ohio TESOL, let me know if you’re interested in test-driving this technology.  We might be able to put one in your hands soon!
