So I’m plotting out my tactical plans for research and scholarship over the next year right now — my imagination being stoked by the completion of my Statement of Scholarship — and I’d like to go deeper into educational technology on a number of levels. I’d like not only to stay abreast of the rapidly-changing face of the technology being used in schools, but also the social implications of that technology, the legal issues behind it, and the technical nuts/bolts/bits of how this stuff works in the first place (including the computer network/programming side of things).

I’m just a user and a self-appointed pundit of ed tech, so I have no idea exactly where to start if I want really to go deeper on this subject. I do know that I’m going to swallow hard and read Digital Natives, Digital Immigrants by Prensky carefully (as opposed to skimmig it as I have done in the past) even though I disbelieve in nearly everything I’ve drawn out of that essay. And I have Friedman’s The World is Flat, which seems to be a seminal work among School 2.0 people, on my bookshelf at work waiting to be read. But what other suggestions would you readers have?

Remember, I’m looking not to become a mindless School 2.0 zombie (that takes no effort at all) but a person who is fluent with all the important aspects of ed tech, including the “tech”.

Martin Weller of the UK’s Open University notes in this blog posting that there is an emerging cultural conflict between the world of higher education and the world of Web 2.0:

[T]he challenge is this – when learners have been accustomed to very facilitative, usable, personalisable and adaptive tools both for learning and socialising, why will they accept standardised, unintuitive, clumsy and out of date tools in formal education they are paying for? It won’t be a dramatic revolution (students accept lower physical accommodation standards when they leave home for university after all), but instead there will be a quiet migration. The monolithic LMSs will be deserted, digital tumbleweed blowing down their forums. Students will abandon these in favour of their tools, the back channel will grow and it will be constituted from content and communication technologies that don’t require a training course to understand and that come with a ready made community.

It’s difficult to say whether how accurate this is, given that students’ knowledge of, and ability to use, those tools is questionable at best. But I think Weller is right that students — faculty, too — are increasingly aware of and irritated by the clumsiness and inflexibility of the tech tools that higher education currently uses. It wouldn’t bother me at all if the Angels and Blackboards of the world were left behind in favor of simpler, more decentralized tools that can evolve throughout a semester according to the needs and capabilities of the members of a class. (This adaptability is a real strength of using a wiki as a course management system, as I am finding out right now in my summer calculus course. More on that later.)

Universities and colleges do seem to face a twofold mandate from students: not only to get in the game regarding technology in the first place, but also to do so in a way that keeps things simple and flexible and student-centered. That can be a tall order for higher ed, which is used to doing things in a highly top-down kind of way.

In this post, I put forth three questions that are good for creating a little objective distance between you and that shiny new technology you saw at the conference are MUST HAVE in your classroom. On the plane to San Antonio, I was thumbing through the SkyMall catalog and found another question to add in to that mix. It was inspired by this:

This is the “Learning Tower and Playset”. As you can see, it’s intended for kids to climb, so they can get up and see what’s happening on a table or countertop that’s normally too high for them. It also doubles as a playset; the platform that the child stands on can be removed and the kid can get inside it, and there are accessories that come with it so the child can use it as a puppet show theater or a make-believe drive-through window.

This product, like the technology we teachers use and think about using, does solve certain problems. My kids love to get up on a chair or stool and watch me cook and sometimes help me cook. But chairs and stools can be unstable, especially given that kids tend to lean over when they are looking at or reaching for stuff on a countertop. Both of my girls have fallen off whatever they were standing on for this very reason. So the Learning Tower solves the problem by giving the child a stable platform with a big base and a sort of enclosure at the top to prevent the child from falling off.

But this product also creates problems as well. The base of this thing is two feet square. That doesn’t sound very big, but that is an enormous chunk of real estate in my kitchen. Even the stepstool that L often uses, which is maybe 12 inches by 10 inches, seems to get under my feet at the worst possible moment all the time. I can’t imagine putting a playset in the kitchen.

So that’s the fourth question to ask when evaluating new technology:

• What problems does this technology create?

And rest assured, every technology creates problems. Take something like Maple, for instance. It’s a hugely useful tool that solves many problems for math students and mathematicians. But it also creates problems. We have to train students, and ourselves, to use it. We have to put up with network installs that never seem to work. We have to think about where the money is coming from to pay for it and maintain our license. And so on. Even the computer itself creates problems, not the least of which is the environmental problem created when the computer is manufactured.

So it seems that to evaluate a new technology, you have to look at a sum balance given by the usefulness of the technology in solving an existing problem, minus the redundancy that technology has with other existing technologies AND the minus the extent to which the technology creates new problems. You’ll never have a problem-free technology, so the question is whether, on balance, the technology solves more problems than it creates is really the key.

I might corner one of the exhibitors here at the ICTCM and ask her/him all four of those questions; a vendor who gives a straight answer to the fourth question might well be worth doing business with.

As you can see in this photo, I made it safe and sound to San Antonio and the ICTCM. The image here is the ICTCM logo being projected on to the floor of the lobby. I guess that makes more of a splash than just putting the names of the groups who are meeting on a board somewhere.

Except for a 90-minute delay in Detroit for a mechanical problem, the trip here was uneventful.  That’s something of a big deal for me, since I am breaking a ten-year long boycott of Northwest Airlines on this trip. The last time I flew NWA was in 1997 when I was interviewing for jobs, and I had to make three trips on NWA. Every leg of each trip encountered a delay of at least two hours. But this time around it was pretty smooth sailing. The pilot even managed somehow to make up 30 minutes of lost time while in the air.

All I have done since getting in to the hotel is check in, get my conference packet, go roaming for fast food, and plan my schedule out. The hotel here is connected directly to the famous San Antonio Riverwalk, and while looking for dinner, I exited the hotel directly into these scenes (click to enlarge):

…which were accompanied by the heavenly smells of the Southwestern fare of the riverwalk restaurants. I’ll be lucky to escape here having only gained a dozen or so pounds.

As for the conference itself, it will be a busy and informative couple of days. Tomorrow we have the keynote address from Frank Hughes on “Real-time virtual environments for teaching mathematics” which sounds like it’s going to be about immersive, virtual-reality-type technology for teaching mathematics. That sounds interesting, and strangely enough this is exactly something that one of my linear algebra students was telling me he hoped I would see while I was here.  Then I will have my Camtasia workshop, followed by my contributed paper session talk at 1:10. Then at 2:10 there’s a contributed paper on a first-year mathematics course on mathematical experiementation; then a session on Octave; then a session on how to choose an online homework delivery system; then a session on something called symbolic geometry software which is supposed to be a hybrid of a computer algebra system and dynamic geoemtry software.

And that’s just Friday, and only a very small sample of the great variety of stuff being presented here. Saturday is just as busy, and I’ll talk about that tomorrow. As the Riverwalk is a feast for the smells and tastes of food lovers, the ICTCM promises to be a feast for the creativity and ideas of people who are passionate about teaching and technology.

At various points throughout tomorrow and Saturday, I’ll have chances to go to the exhibit hall as well. Although I have to say I am a little disappointed, because evidently there are fewer than 20 exhibitors in all here. I was expecting something like at the Joint Meetings where the entire convention center floor is wall-to-wall exhibitors. At least this will allow me to get some face time with each one, and who knows, maybe even some impromptu video interviews.

Unfortunately, the internet access at this hotel is not wireless except in the lobby, which means that I will only be able to post when I am back in the room. I will publish some of the posts on a delay to spread them out during the day, but they won’t all be in real time. I will refrain now from the rant I so desperately want to give against the Marriott hotel here — which advertises high-speed internet but charges you $10 a day to have it. Come on Marriott, what would it cost you to set up a few wireless routers and offer net access to guests?

Anyway, stay tuned for more.

Tomorrow is a travel day as I fly down to San Antonio for the ICTCM. I’m leaving from Indy around 11:00 AM and am supposed to (!) arrive around 4:30. All I  plan to do tomorrow is travel, check in to the hotel, and maybe grab a  program and plan my schedule for the conference. Given that my most recent airline experience was sheer hell, I’ve learned not to plan too much on a travel day since a “day” can end up being about 40 hours long.

I’m excited about the conference, especially at the prospect of meeting some of the folks I’ve been blogging with for years and at learning lots of cool new things. But I don’t look forward to missing my wife and kids. I don’t travel much, so it’s not easy for the girls (ages 2 and 4) when I’m gone for a few days. P, our 2-year old, is picking up speaking English very rapidly these days, and tonight she looked up at my wife and said — clear as day — “Miss daddy!” It’s a reminder that despite the reimbursements for travel and hotel that I’m getting from my college, there is still a cost involved in going to these conferences, and it’s up to me to make it worth that cost.

I hope to check in with another post once I’m there tomorrow, but I’m not planning on blogging until then. However, you can follow me on Twitter for more regular (if less substantive) updates. Yes, I know I just bashed Twitter addicts and yet there I am using it.

Glad you asked. Pretty well, all things considered. My talk, having the catchy (?) title of “A Tale of Two Wikis”, is about creativity in upper-level math courses and how I used wikis to facilitate collaboration on creative projects in two of my upper-level courses. It’s a subject I enjoy talking about, and I enjoy showing off the wikis that my students made in those courses. But that’s something of a problem now, since I only have a 15-minute time slot to work with, and only 10 of those minutes can be taken up with an actual talk.

Yesterday I had a practice run through my talk with a few of my colleagues present. It took me 12 minutes to get through the entire talk, but I lost about a minute because I had forgotten to sign into my Wikispaces account prior to showing how the wiki-authoring process worked. So modulo that glitch, I think I’m actually OK time-wise. The only other issue with the talk was that one graphic — a full-color graphic of Bloom’s Taxonomy with text labels on each stage — looked fine on my laptop monitor but was illegible on the projector screen. (Black text on dark red and orange background.) So I need either to redo that graphic myself and fix the legibility, or else just plan on reading the text labels.

Now begins the preparation for the presentation itself, which is basically centered around having a Plan B, C, D, …, Z just in case Plan A (= show the presentation off my laptop using Keynote, a wireless internet connection, and an LCD projector) fails when I get up in front of the audience. My contingency preparations include:

• Having transparencies of my Keynote slides.
• Having PDF’s of my Keynote slides available on a CD.
• Having PDF’s of my Keynote slides available on a flash drive in case CD fails.
• Having Power Point versions of my Keynote slides available on Google Presentations in case the internet works by my hardware doesn’t. (Yeah, that’s unlikely.)
• Having Quicktime versions of the walkthrough of my student wikis in case internet doesn’t work.
• Having electronic copies of the slides, the movies, and the handouts for the talk in an email on GMail.

Basically I have been through so many presentations that turned into disasters because some piece of technology didn’t work, that I now plan for any talk, no matter how simple or short, as if all the possible outcomes are equally likely. Paranoia: It’s not just for breakfast anymore!

One thing that is sure to happen at the ICTCM later this week is that I will be inundated with tech stuff (from the exhibit hall) and ideas about using tech stuff (from sessions and workshops) in my teaching. Of course it’s good, clean fun to play around with tech stuff, and it’s good to come into contact with other people who are passionate about technology in teaching and with their ideas. But there’s a danger here as well: You might get so swept up in the zeitgeist of the conference that you begin to uncritically adopt all kinds of tech stuff and tech ideas for inclusion in your classroom without really evaluating it.

So when I am at the conference, there are three basic questions that I will ask whenever encounter tech stuff or ideas. They are the same questions I have asked for years about technology, whether that technology is for education, entertainment, home improvement, or whatever:

1. What does this technology do?
   
2. What problem does this technology solve?
   
3. What technology currently exists to solve this problem, and in what sense is this product an improvement over the existing technology?

This series of questions has, in the past, provided me with a buffer of objective distance from interesting-looking tech and forced me to think critically about things I see, rather than just snapping up whatever looks cool or interesting and blindly moving forward with it in my classes. Forcing yourself to see new technology from a problem-solving point of view is a pretty good exercise in general.

I daresay that there are a lot of edubloggers out there that could stand a little more objectivity and critical thinking in how they approach technology; sometimes ed-tech blogs put off a sort of glassy-eyed cult-like aura, like the blogger wants nothing than for you to drink the Kool-Aid of the latest read/write Web 2.0 social network/digital storytelling thing they just spent 36 hours deconstructing. (I think the delusion about digital natives arises mainly as a product of the haze of one’s own unbridled indulgence in educational tech. Spend enough hours wasting time on Twitter and you can convince yourself that 24/7 sharing of personal acts and information is actually normative.)

If a technology product I am considering cannot be described easily in terms of its basic functionality, or if it is not in place to solve a clearly-defined problem, or if it does not improve significantly upon existing technology whose functionality is well-defined and which solves a clearly-defined problem, then most likely it’s not going to make me be more productive or my students learn better.

I think these questions actually originated with Wendell Berry, not somebody you’d normally associate with the ed-tech stormtroopers in the blogosphere. He’s something of a Luddite, I know, but an intelligent one and a person whose caution with new technologies I have always admired.

The Wired Campus is running a series of articles on using Twitter, the popular micro-blogging platform, as a classroom tool. Here’s the first article (interesting stuff in the comments there), and here’s a followup with a short video from a Twittering professor. And here’s a more lengthy article from Chronicle.com.

Twitter does appear to provide good backchannel discussion opportunities for those who are motivated to use it productively, and as a corollary there are some interesting out-of-classroom student interaction possibilities there. But my experience with any form of online communication is that students like it if they are pushing the information to people of their choosing (such as IM) but not if class stuff is being pushed to them (such as Twitter or even regular email). Control of information is a really big issue with students, and it profoundly creeps them out sometimes when professors presume to include them in backchannel conversations about class.

On Thursday I’ll be heading south, out of the deep freeze of late winter in Indiana to lovely San Antonio, TX for the International Conference on Technology in Collegiate Mathematics (ICTCM). This is my first time to an ICTCM, and I’m genuinely excited about going. (Which is something I can’t say about very many conferences I have attended.)

I’ll be giving a talk at 1:10 on Friday about some stuff that I have been doing with wikis in my upper-division classes lately and about the potential role of wikis in advanced math courses in general. Of course, my talk’s time slot is only 15 minutes long, and they tell me the talk should really only be 10 minutes long, so my talk is going to be more of a conversation-starter (at least I hope so) than it is anything nearly comprehensive .

Earlier on Friday, I’ll be attending a workshop on Camtasia, which I am considering as a replacement for Snapz Pro X as my screencasting software. I’ll have more to say about screencasting and screencasting software a little later. It turns out that our IT department at the college use Camtasia to do tutorial videos, and they apparently like it very much.

And apart from those two things, which constitute sort of the official reason I am going to the ICTCM, there will be lots of other fun stuff happening. For one, I’ll be meeting up with other edubloggers — notably Maria Anderson from Teaching College Math Technology Blog and Scott Franklin from Natural Blogarithms. If you’re reading this and will be there with nothing to do Friday night, join us in the lobby of the hotel and have dinner and hang out.

Also, since the Camtasia workshop and my talk all happen between 10:30 and 1:30 on Friday, the entire rest of the conference is wide open for me to attend other stuff. They haven’t posted the full schedule at the ICTCM web site yet, but the 45-minute workshops look pretty interesting, and there ought to be a huge diversity of short talks like mine. And don’t forget the vendor exhibits, which are always among the coolest things at math conferences.

In the spirit of educational technology, blogging, math, and all the other stuff that makes Casting Out Nines more or less what it is, I’ll be blogging the conference as I go, including photos and video (hopefully; I’m taking the camera, at least). You never know exactly how much down time you’ll have at a conference, but I hope to keep a steady stream of posts coming from Thursday through Saturday.

As I told my linear algebra class yesterday, this is not only a math conference but a technology conference too — so this is the sanctum sanctorum of geekhood. Don’t you want to be along for the ride?

I just made this flowchart for the Calculus Preparation lesson coming up next Monday, which is on how to model nonlinear data. Click to enlarge:
