Hi, I wanted to throw out an idea for ITS2010 and see if anyone is interested. At AIED09 we had a tutorial on EDM and it was well received. It would be nice to have another one at ITS this year. Tutorial proposals are due Friday January 29. Typically, tutorials are half a day or a full day. I realize that even half a day might seem like a large amount of time to fill, but there are even smaller increments that are possible. Consider the typical tutorial day: ~90 minutes of tutorial coffee break ~90 minutes of tutorial lunch ~90 minutes of tutorial coffee break ~90 minutes of tutorial Do you think you can give a tutorial for *90* minutes? If you're going to show people how to use a particular technique, that's enough time to explain the problem you're trying to solve, where it applies, the insight behind your approach, the technical details, and some applications where you analyze some real data (either you do it on screen, or groups analyze and you wander around to help). I think a *great* EDM tutorial could be made from 2 (for a half day) or 4 (for a full day) of these 90 minute sessions. In addition to simplifying your lives, it makes things easier for attendees since if there is some technique they don't care about, they know when it will be discussed and can make other plans for that block of time (pop into a workshop, hang out in the tropical paradise of Pittsburgh, etc.). If you're interested, send an email to the list. If you're not interested in talking, but there is a topic someone knows you want to know more about, send an email to the list. Who knows, it might shame that person into volunteering :-) In the interests of full disclosure, I'm co-chair for Workshops and Tutorials, so have a vested interest. But I'll put some skin in the game. If we get some momentum behind this and need a second or fourth person to fill up the day, let me know and I'll propose one of the 90 minute sessions. If we get two or four sessions without me, that's fine too. joe -- Joseph E. Beck Assistant Professor Computer Science Department, Fuller Labs 138 Worcester Polytechnic Institute
