[Ed. note: This post was originally written on March 13 while at the ICTCM, but I ran out of time on my $12.95 per day internet access before being able to post it and only now have had the chance to get back online. So it's about 36 hours out of sync.]

Slower day at the ICTCM than yesterday. For one thing, I took some time out in the morning to get the MATLAB course prepped for Monday; and I needed time to finish some grading in the afternoon. But I manage to have a pretty productive day nonetheless.

The main event — one of the primary reasons I came here — was a Geogebra 3.2 minicourse this morning. I’ve been a diehard Geometers Sketchpad user for a long time, but after becoming aware of Geogebra lately, I began to wonder if it might be time for a switch. I have no problem with the usability and features of Sketchpad, but if there’s free software out there that is pretty close to the same quality, the possibility of simply installing it everywhere (like we’ve done on campus with Winplot) is pretty enticing. The question was whether Geogebra’s features and usability matches up well with Sketchpad’s.

After the minicourse, I’d say the answer to that question is definitely “yes”. Particularly impressive is Geogebra’s ability to export entire constructions to HTML as an interactive web page. I have some definitely plans for this kind of thing for the class now. There’s more to learn — unfortunately we didn’t go very deep with the software in the minicourse — but definitely Geogebra will be the software platform for the geometry course this fall. Now I have to decide on a textbook — or to go without. Hope to blog on that later.

Also today I attended a session on using clickers in mathematics courses. I’ve been following Derek Bruff on Twitter for some time (he’s an assistant director at the Vanderbilt Center for Teaching, where I used to be a Master Teaching Fellow) and have gotten interested in using clickers through his work with them. This was a general survey talk, but very well done and it definitely increased my interested in folding clickers into my teaching mix at some point.

Overall the ICTCM is one of the better conferences out there for people who are interested in math, education, technology and the intersections between these. Look for the announcement for ICTCM 2011 coming soon!
