Stuff about using computers to help people teach and learn better.

Learning with and about Technology

I'm Jay Pfaffman, an instructional techology professor at the University of Tennessee. If you are interested in studying instructional technology here, please see the ITHES web site. You might find me in my office in 443 Claxton.

Here you can find out about my courses and research. I also post in the news that relates to schools and technology. The rants section discusses things bug me and, as such, should become things that I do research about to try to fix. I enter some pages here as blog pages, which are sort of like news or rants except that they're probably not fully developed ideas. Finally, there's a section called ideas that's just quick little ideas that, hopefully, students or other collaborators will see and be interested on working on. Look here for ideas for projects that you might do for my (or other people's) classes.

Other information about my research can be gleaned from my vita. You can contact me at jay@utk.edu.

Upgraded Drupal to 6.12

A friend sent me a message today to say that this site was down with some cryptic error message. In the course of solving that mystery, I found that I could delete something like 200MB of data from the database. Doing so took several minutes, but once I did I was able to successfully upgrade the old Drupal from 4.x to 5.x and then from 5.x to 6.12. I've spent a couple hours lately trying to do the upgrade and am happy that I've finally accomplished it.

Boring details follow.

Who Needs Educational Research?

I just got an email sent to a list for school principals that says:

Do you use READING-PROGRAM as an intervention program/supplemental program and have you found it to be successful? Do you like it and is it worth the cost??

This, I think, is how people who make decisions in and about schools get their information. They ask their friends. The question wasn't "Does anyone know of any evidence that this program DOES SOMETHING GOOD?" The question is "Do you like it?"

What World Do We Technology Educators Live In?

I'm still trying to make sense of technology in schools. A classic work is Cuban's (1986) Teachers and Machines: The Classroom Use of Technology Since 1920. In it, he discusses how educators, or educational researchers, have believed that film, radio, television, and computers, would change everything. They didn't. The curious thing to me is why people thought these things would revolutionize schools. No one thought that they were going to revolutionize much else. Sure, they created industries and jobs, but no one was saying "Radio is going to completely change the way that we practice law" or "television is going to revolutionize the way that we design bridges." They didn't even say it about psychology, sociology, or anthropology. But yeah, it's totally going to change schools.

Cuban subsequently made the same can't-change-schools argument about computers and the internet in Oversold and Underused: Computers in the Classroom (2001, see also this journal article or here). He did this work in some schools in Silicon Valley, arguing that if the computer stuff wasn't making a difference there, then it probably wasn't anywhere else. That seemed right. And it was. Even in these privileged schools with tech-savvy kids in a tech-savvy district with what counted as lots of computers, stuff was pretty much the same.

His "high-access" schools had student-to-computer ratios of 4 and 5 to one, as compared to 6:1 nationally in the 1998-1999 school year. 64% and 84% of classrooms had internet connections as compared to 44% nationally. Today, nearly every classroom has an internet connection, but the student to computer ratio hasn't changed much. And the 4:1 or so that's in most schools often counts computers that students don't have access to, as well as those that are not actually working or capable of running an up to date OS or web browser.

Outside of schools professionals often have more than one computer: a desktop, a laptop, a PDA or iPhone, perhaps another computer at home. And we are not apologetic if we do not use them in a particular, technologically advanced ways. Outside of a school, no one would ever say, as one of Cuban's teachers did, ``If we're just word processing, we may as well have typewriters'' (p. 814, in the article above). Did you get that? This "we're not using them in `good enough' ways" notion is fairly common in studies of schools with laptops.

An article in the New York Times describes several schools who were abandoning laptop programs because they didn't show increased learning. There were studies that showed that computers didn't result in increased learning in the 1980 that showed increased computer power didn't result in increased productivity (e.g., this one, also here). But people didn't really take it seriously. No one thought, well, maybe we just shouldn't use computers. But if we're talking about schools, it's completely reasonable to say, "Yeah, computers really aren't worth the trouble."

On Computers as a Change Agent

My job talk was based on the notion of using various technology tools as a Trojan Horse. For example, Webliographer, arguably the first social bookmarking program, was a way to use web bookmarks, a then-familiar concept, and "sneak in" a way for people to collaborate and share. Or the online testing system I developed could be snuck in as a way to deliver multiple-choice tests, but could become a means for providing formative assessments that give students opportunities to learn.

Tech folks frequently buy in to this Trojan Horse metaphor. Often, we (they?) think that by sneaking computers into classrooms under various auspices (e.g., it's the 21st century, the Internet is Really Important) with the real hope that what will happen is that teachers will embrace notions of constructivism, will become more student-centered and will change our educational system. There's an AERA SIG called Technology as an agent of change in teaching and learning. I'm even a member. I'm all for these changes and, indeed, became a teacher because I hated school and thought that it really needed to change. I think I hoped and thought that computers could be a part of it (but I may have just thought that it would be a good idea for someone who knew about computers to be teaching about them).

It strikes me today that though I'm all for these changes, I don't think that the promise of those changes is the point. I continue to be struck that we in education seem to feel obligated to come up with some Really Good Reason to use computers in schools. So much so that, for example, teachers in schools where every kid has a laptop, lament that they're "only" word processing and using the web. They think that they need to have kids creating movies or doing something that's "not possible" without computers. Otherwise, they're somehow "wasting" the computers.

I find this absurd.

Virtually everywhere else, whether it's an ad agency, a police station, a fast food restaurant, or an unemployed writer's basement apartment, people use computers. And what do they do with the most of the time? They use word processors, the web, and communicate with people via email, blogs, and even Facebook. You don't hear lawyers say, "You know, we're using these computers only to research cases and write briefs. It's such a waste. If we're going to spend all this money on computers, we should be creating videos and interactive web sites." But so it is in education.

My message is pretty much, "Hey, here's a way to get the 2:1 to 4:1 student computer ratio into classrooms. It costs almost no money. Teachers and students know how to use them. Teachers didn't really know what to do with computers 10 years ago, but they do now---the whole "internet" thing has sorta caught on. Rather than waiting a couple more years for netbooks to get cheap enough, we can do this now. Here's how it's worked in several schools in which I didn't have time to (1) do an intervention, (2) provide technical support, (3) train teachers to use them."

This message is not very compelling for several reasons. I hear things like:

  1. That sounds too good to be true, so it must be.
  2. I used Unix in the 90s. It sucked.
  3. I use Mac/Windows. There's no way I'd going to change to something I haven't heard of.
  4. Just putting computers in schools won't change things.

Perhaps I can figure out an argument that these things don't apply to.

SmartFit, forging elite intelligence

At the beginning of February I started doing a fitness program called CrossFit. Having not been in a gym class or played organized sports since 7th grade, I'm quite surprised to find that I now know a bunch of ways to, for example, pick up barbells. Each day the CrossFit web site has exercises posted that anyone can do (I follow those of CrossFit Knoxville). It's different every day, and there are a set of benchmark exercises that will, for example, have you do something as many rounds as possible in a given time (AMRAP, in the lingo) or to complete a certain number of repetitions in as little time as possible. In a conversation about CrossFit Daniel Wilson said that he applied CrossFit principles to his academic work, and would, for example, say that he was going to read 100 pages for time. This got me thinking about whether an academic program could be developed using these same principles.

Why We Teach

I have been thinking lately about how it is that it's very hard to recruit people to be teachers, scientists, and especially science teachers. When I talked to one of the most intelligent kids I taught some years after he graduated from college he explained that there was no reason to go into a technical field, there was no money in it. What did he do? Traded derivatives on Wall Street.

Yesterday I got a friend request from a student I taught in my first job (from 1987-1990). Here's what he wrote on my wall:

why shouldn't i seek you out? i graduated with a computer science degree. your classes at "perk" were awesome. to this day i will never forget you retrieving info from a hard drive. i wanted to know that stuff!!! unfortunately, i was a u.s. history major in college - then i switched to computers. i went on to graphics and finally got to edit corporate videos on an avid for a fortune 500 company. thank you for waking my mind up to that field! take care -

So it seems that something I did helped someone turn out OK. I'm not quite sure how these two stories are connected, besides they're both people that I taught. I guess it's good to know that when I was flying blind as a new teacher establishing a computer program where none had existed (something that I'm not sure I'd do again) I did some stuff right. I'm glad that Chris learned enough about computers to make it a career, I'm still worried, though, how our country is going to again convince people like Nimrod that contributing to knowledge and making stuff is a better career choice than manipulating numbers to "make" money and destroy our economy.

On e-portfolios (or double-dipping)

I'm double-dipping. This is an email I sent a student who is interested in doing some work on e-portfolios. 600 words in, I figured it was just the kind of thing that I'm trying to get us to think about in IT695 this semester. So, here it is, edited a bit.

I just reviewed an article about e-portfolios for a teacher education journal. I wasn't convinced that the e-portfolio system was doing anyone any good and one of the solutions was better training. (I like to point to the extensive training that the millions of people who use blogs and Facebook require in order to use those tools effectively.)

OK. Learn.occ.utk.edu and ubiquity.utk.edu were inaccessible because my machine had crashed.

I set up my blog and here it is.
