Moldy Oldies show returns!

After a four-week hiatus, I’ve decided to return today for a “first day of summer” edition of the Moldy Oldies show on WCUR. It will be from 4 to 6 p.m. this afternoon (although I may decide to start a bit earlier). My focus today will be on “songs of summer,” although I will be happy to play requests as well.

If you are unfamiliar with the Moldy Oldies show, this is a program I’ve been doing for many years on WCUR. As faculty adviser to our campus radio station, I feel that it is important for me to spend some time every week “in the trenches” doing a show on the air. Besides, I enjoy playing music from an earlier generation. So on most Thursday afternoons during the school year, I’m on the air from 4 to 6 p.m. I typically play mostly classic pop music from the 1960s and 1970s, with occasional tunes from before or after these decades. I often have a guest or two each week, and regularly feature an interview segment at 5 p.m. (coordinated by my former student and now “Associate Producer” Kathy Schlegel).

I don’t know how many more shows I’ll do this summer, but I’ll try to keep things going for at least some of the time. Since I’m on sabbatical leave this fall, I hope to have guest hosts fill in for me, as I won’t be able to be on campus. Doug “Mush” Carrol has said he would do a few, and I believe Kathy will also pitch in to keep things going with the interview segment.

So if you want to enjoy some tunes from the past, listen to WCUR-FM 91.7, or online at www.wcur.fm, Thursday afternoons from 4 to 6 p.m. To call in requests, dial 610-436-2478, or send an instant message to AIM screen name wcur919.

Mossberg calls centralized campus IT a “poisonous force”

Many writers in the blogosphere have commented on The Wall Street Journal‘s Walt Mossberg revealing of his pre-release iPhone to leaders of higher education at a recent forum hosted by The Chronicle of Higher Education. But while any iPhone news is big news nowadays, another aspect of his presentation may have even more significance to those who have an interest in educational technology, especially as implemented at colleges and universities.

During a speech at The Chronicle’s President’s Forum, Mossberg used harsh but pointed words to express a sentiment shared by many academics (but rarely expressed so publicly). In typical Mossberg fashion, he described centralized information technology departments, such as those often found in larger colleges and universities, to be “the most regressive and poisonous force in technology today.”

That may be overstating the case a bit, but not by much. I have worked with numerous campus IT departments over the past thirty years, and I know that most people who work in these departments try hard to provide a valuable service. But the problem Mossberg touched upon typically isn’t the fault of those who work in campus IT departments. Rather, it’s mostly because the primary rationale for centralizing technology efforts is rarely to support eduction, but to save money.

Unfortunately, centralizing technology doesn’t always save money, at least not at the micro level. I don’t know how often I have found that the contract price negotiated with vendors for technology exceeds the price a consumer could get at retail. To give a simple example, one of the secretaries in our Dean’s office recently asked where she could get a USB “thumb drive.”  I was able to pick up a 1 GB drive for her the next day for under $20.  Another secretary in the same office ordered a 512 MB drive from central purchasing for $50, which arrived a week later. I can think of many similar examples of price and delivery disparities, from printers to hard drives to software to computers.

Because IT departments usually negotiate contracts well in advance of the time of purchase, vendors can give the appearance of a deep discount at the point of negotiation. But a few months later, when purchases are actually made, what once seemed to be a bargain becomes a bloated price. “Locking in” a price for technology may help with budget forecasts, but it can also preclude taking advantage of rapidly falling prices in the marketplace.

This problem is particularly acute in academia, where internal purchasing decisions can be very cumbersome. It’s not unusual at our institution for weeks, even months to pass between purchase requisition and product delivery. That’s why our department has gradually moved away from our centralized IT purchasing department to buy much of what we need to support faculty and staff. We can get precisely what we need in much less time, and often for less money. Doing so typically results in an ominous warning from our IT folks that we are buying products that “aren’t officially supported” by them. But that usually isn’t much of a problem, since such support is often only a little better than what can be received from the vendors directly (and sometimes not as good).

True, there are some faculty who need a lot of hand-holding with technology, and they can potentially benefit from the support provided by centralized IT departments. More often than not, however, most faculty would prefer to have today’s technology today without official support, rather than yesterday’s technology the day after tomorrow with the promise of ongoing support. And unfortunately, such support can be motivated as much by the desire to control costs than to improve technology utilization.

So Mossberg may have hit the nail on the head with his comment. Centralized IT by its very nature can be very regressive, since it needs to regularly “freeze” adoption points in order to systematically support technology. And in an academic environment, with the constant pressure to push forward the boundaries of public knowledge, such a regressive force could also be a poisonous one.

Perhaps one antidote for this “poison” could be the adoption of a more distributed model of technology implementation, where faculty, administration and students all play a part in “pushing the envelope” of educational technology. And that’s something that academic librarians have a lot of experience with, a point I have been trying to get people to listen to for years. Until we move from seeing computers as “bricks and mortar” to seeing them as “books and journals,” higher education will continue to struggle with technology adoption. We need to encourage campus IT leaders to see beyond the bottom line, by helping raise the status of technology in the educational enterprise from a physical expense to an intellectual asset.

Booker T. Washington National Monument

On our drive home from our recent Caribbean Cruise, my wife and I decided to skip I-95 and try a more inland route, closer to the Appalachian Mountains. As a result, our route took us through Rocky Mount, Virginia, and the nearby Booker T. Washington National Monument. We enjoyed a visit to this picturesque and informative memorial to one of the most noted African Americans in higher education.

Many people have heard of Booker T. Washington, but they may not know why he was significant. As the helpful guide at the Monument told us, a lot of people confuse Booker T. Washington with George Washington Carver. That’s not surprising, given that both were African Americans, both were born into slavery, both would grow up to become famous educators, both taught at the Tuskegee Institute, both worked to improve race relations in the years following the Civil War, both have National Monuments honoring their memories, and both had Washington in their names. But there were two very different people: Booker was from Virginia while George was from Missouri; Booker founded the Tuskegee Institute, and later invited George to join the faculty; Booker was the more controversial figure, called “The Great Accommodator” by W.E.B. DuBois because he favored cooperation over confrontation in the fight for civil rights; George was perhaps the more widely remembered figure among school children because of his numerous inventions and innovations centered around peanuts.

I’m hardly an expert on African American history, but I’m glad I spent some time learning more about the life of Booker T. Washington at the Monument’s Visitor Center. Not only was it an informative and interesting stop, the Monument is in a beautiful setting, with well-maintained grounds. There are farm animals and crops growing in the fields, a handful of recreated cabins and barns from the mid-1800s, and numerous interpretive signs helping illustrate the natural environment that Booker T. Washington experienced as a young boy growing up as a slave in Franklin County, Virginia.

Getting chummy with Chumby

Chumby is the name of a small device that displays “web widgets.” It connects wirelessly to the internet to display a rotation of user-selected content. It’s still in the testing stages, but supposedly will be on sale this summer, and will cost less than $200. But you can create your own “Virtual Chumby” now by establishing an account on www.chumby.com

Here’s the Virtual Chumby I created just a few minutes ago…

There may be some aspects of Chumby that could be useful in my sabbatical project (to create a prototype “textbook in an iPod”). The touchscreen interface and Flash playback is promising, although at the moment it doesn’t appear able to support streaming video.

Podcasting Tips and Tricks

[Below is the text of my presentation at this year’s RECAP conference.]

For the past three years, I’ve been podcasting my lectures in the introductory course in mass communication I teach at West Chester University. Students have often told me that the lecture podcasts have been a valuable study aid, and have helped make the large lecture hall experience more manageable and enjoyable.

Despite an early concern that attendance might suffer from making my lectures available as podcasts, I have not found this to be a problem. A comparison of the Blackboard tracking data for the podcasts I did during the 2005-2006 academic year found no significant correlation between podcast use and attendance. Subsequent surveys found most students use podcasts as a supplement to the class lecture, rather than as a substitute for attendance.

Here are a few “tips and tricks” I have learned from my experience with podcasting lectures…

Pay attention to the audio. A lecture is not very valuable if the students can’t hear it. Sometimes I have used the built-in microphone on my laptop computer to record my lecture, and as long as I don’t stray too far away from it, this seems to work fine. But since I tend to move around a lot during my lectures, I’ve found I achieve better results when using a separate microphone. I have used small digital audio recorders with some success, although it pays to invest in a good one (I use the Sony ICD-SC25). Newer iPods have the ability to directly record high-fidelity audio with inexpensive add-ons like the MicroMemo from XtremeMac; this company also sells a matching lapel microphone called the MemoMic that is ideal for lectures.

Syndicate your podcasts. At first, I simply uploaded the digital recordings of my lectures to Blackboard, but this isn’t really podcasting, as the content isn’t “syndicated” using a “feed.” Since the version of Blackboard we use on my campus lacks the ability to create such feeds, I use the free service at feedburner.com. Feedburner helps me create the RSS feed that I then insert as a content item on Blackboard (or any web page). They even provide me with a free web page for the podcast feed (for example, here’s the feed page for my Spring 2007 course in mass communication). Although they don’t host podcasts, other sites do, including archive.org and putfile.com.

Provide more than just audio. While my first podcasts were simple audio recordings, most of my podcasts now include graphics that can be displayed along with the audio. Sometimes called “enhanced podcasts,” this kind of podcast takes advantage of the ability of digital audio files to store and display graphics that change according to chapter markers embedded in the file. Originally intended as a way to provide “album art” for music files, this feature can also be used to display PowerPoint slides or other graphics that are part of a lecture. A program that I have been using for the past year that greatly aids in the process of creating “enhanced podcasts” is ProfCast (www.profcast.com). This is an inexpensive tool that can work with both PowerPoint and Keynote presentation software, allowing you to record your podcast while giving a lecture. (At the moment, ProfCast is only available for the Mac, although a Windows version may be forthcoming.)

Consider vidcasts. Video podcasts (vidcasts) are growing in popularity, and are becoming easier to produce. Because most of my lectures are an hour or longer in length, I’ve been hesitant to create video podcasts of my lectures, since these can be very large files. But with bandwidth issues subsiding and compression techniques improving, lecture vidcasts may soon become the norm. One promising tool for video podcasters is VODcaster (www.twocanoes.com/vodcaster/). Although it is not as easy to use as ProfCast, it does offer a number of useful features, and it’s free.

Use free web tools. There are plenty of web sites that offer free tools for podcasters. Here are a few:
