[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!

What I learned at the ICTCM, day 1

Busy day here at the ICTCM. I need both an extended time for brain-dumping and a full night’s sleep, and I think the latter is going to win. So here’s a brief listing, in no particular order, of some of the standout items I’ve learned today.

  • I learned first thing this morning that rigorous, scientific scholarship of teaching and learning does actually exist, and it’s being done by Dave Pritchard of MIT. Prof. Pritchard was our keynote speaker this morning. In his words, he has basically forsaken a successful career in atomic physics (in which role he mentored or taught three Nobel laureates) to devote his energies to physics education. His keynote this morning gave me enough reading material for a semester and a whole new outlook on what educational research could look like.
  • I learned (through Pritchard’s keynote) that there is a school of thought that says partial credit in math and science courses should not be given, because — and I quote — “Partial credit rewards partial understanding”. More to think about here.
  • I learned that, thanks to the research of Pritchard and his cohorts, there is a growing field of educational data mining, or one might say educational informatics, out there, designed to take data from online assessment tools and making observations about student learning. There’s even a journal.
  • I learned that the difference between novice and expert behaviors in learning pretty much describes all the issues I’ve encountered with the MATLAB course and other courses I’ve taught.
  • I learned, through Scott Franklin’s prezi on this subject this morning, that online lectures can be done that aren’t just lectures.
  • I learned that Geogebra is pretty cool, and I’ll learn more tomorrow as I take a minicourse on that software.
  • I learned there’s a whole website out there — and probably more than this one — for project-based learning ideas.
  • I learned that MATLAB has an interactive GUI…. for creating interactive GUI’s. Definitely something to play with later.
  • I learned that Gino’s East Pizza is among the best stuff I’ve ever ate, and the copious amounts of it in my stomach right now are a strong argument for sleeping over brain-dumping.

Tomorrow will be a Geogebra minicourse, as I mentioned, and more sessions which I haven’t mapped out yet. We’re getting sporadic wireless access, so I’m able to tweet a lot. More to come!

ICTCM underway

It’s a beautiful day here on the shores of Lake Michigan as the ICTCM gets underway. It’s a busy day and — to my never-ending annoyance — there is no wireless internet in the hotel. So I won’t be blogging/tweeting as much as I’d like. But here’s my schedule for the day.

  • 8:30 – Keynote address.
  • 9:30 – Exhibits and final preparations for my 11:30 talk.
  • 10:30 – “Developing Online Video Lectures for Online and Hybrid Algebra Courses”, talk by Scott Franklin of Natural Blogarithms.
  • 11:10 – “Conjecturing with GeoGebra Animations”, talk by Garry Johns and Tom Zerger.
  • 11:30 – My talk on using spreadsheets, Winplot, and Wolfram|Alpha|Alpha in a liberal arts calculus class, with my colleague Justin Gash.
  • 12:30 – My “solo” talk on teaching MATLAB to a general audience.
  • 12:50 – “Programming for Understanding: A Case Study in Linear Algebra”, talk by Daniel Jordan.
  • 1:30 – “Over a Decade of of WeBWorK Use in Calculus and Precalculus in a Mathematics Department”, session by Mako Haruta.
  • 2:30 – Exhibit time.
  • 3:00 – “Student Projects that Assess Mathematical Critical-Thinking Skills”, session by David Graser.
  • 5:00 – “Visualizing Mathematics Concepts with User Interfaces in Maple and MATLAB”, session by David Szurley and William Richardson.

But first, breakfast and (especially) coffee.
