Patent Filing the Future of Instructional Podcasts

Glad to see Apple thinking about some new ways to produce and distribute podcasts.

AppleInsider | Apple filing takes Podcasts to the next level

It’s quite possible that this patent filing may not lead to anything concrete but the very fact that Apple devotes some time to the issue could lead to interesting things. In fact, other manufacturers may be motivated to move in this space and this might have powerful effects on educational technology.

Visualizing Touch Devices in Education

Took me a while before I watched this concept video about iPhone use on campus.

Connected: The Movie – Abilene Christian University

Sure, it’s a bit campy. Sure, some features aren’t available on the iPhone yet. But the basic concepts are pretty much what I had in mind.

Among things I like in the video:

  • The very notion of student empowerment runs at the centre of it.
  • Many of the class-related applications presented show an interest in the constructivist dimensions of learning.
  • Material is made available before class. Face-to-face time is for engaging in the material, not rehashing it.
  • The technology is presented as a way to ease the bureaucratic aspects of university life, relieving a burden on students (and, presumably, on everyone else involved).
  • The “iPhone as ID” concept is simple yet powerful, in context.
  • Social networks (namely Facebook and MySpace, in the video) are embedded in the campus experience.
  • Blended learning (called “hybrid” in the video) is conceived as an option, not as an obligation.
  • Use of the technology is specifically perceived as going beyond geek culture.
  • The scenarios (use cases) are quite realistic in terms of typical campus life in the United States.
  • While “getting an iPhone” is mentioned as a perk, it’s perfectly possible to imagine technology as a levelling factor with educational institutions, lowering some costs while raising the bar for pedagogical standards.
  • The shift from “eLearning” to “mLearning” is rather obvious.
  • ACU already does iTunes U.
  • The video is released under a Creative Commons license.

Of course, there are many directions things can go, from here. Not all of them are in line with the ACU dream scenario. But I’m quite hope judging from some apparently random facts: that Apple may sell iPhones through universities, that Apple has plans for iPhone use on campuses,  that many of the “enterprise features” of iPhone 2.0 could work in institutions of higher education, that the Steve Jobs keynote made several mentions of education, that Apple bundles iPod touch with Macs, that the OLPC XOXO is now conceived more as a touch handheld than as a laptop, that (although delayed) Google’s Android platform can participate in the same usage scenarios, and that browser-based computing apparently has a bright future.

Educational Touch: Handhelds in Schools

The more I think about it, the more Touch-style handhelds seem to make sense in educational and academic contexts. They don’t need to be made by Apple. But Apple’s devices are inspiring in this respect.

Here’s a thought, which would be a deal-maker for many an instructor: automatically turn off all student cellphones. A kind of “classroom mode,” similar to the “airplane mode” already on the iPhone. And it could apply to non-phone devices (i.e., the iPod touch and future models in those Touch lines). An instructor could turn off all audio out from the all the handheld devices in the room. Or turn them all on, if needed. This could even be location-based, if the devices have sufficiently precise positioning systems.
To go even further, one might imagine some control over what apps may be used during class. Turning off games, for instance. Or chat. Or limit browsing to the LAN. Not “always off,” mind you. But selectively opting out of some of the handhelds’ features. Temporarily.

In most situations, such controls seem overly restrictive to me. Apart from preventing cellphones from ringing during lecture, I typically want to let students as free as possible. But I do know that many of my colleagues (not just admins) would just love it if they could limit some of the things students can do during class with such devices.

One obvious context for such limits is an in-class exam. If they could easily prevent students from using non-allowed materials during an exam, many teachers would likely appreciate the convenience of exams on handhelds. Just imagine: automatic grading and grade reporting, easy transfer of answers, access to rich multimedia content, seamless interface…
As was obvious to me during the Apple event yesterday, Touch-style handhelds could be excellent tools for “distance education.” Learners and teachers could be anywhere and the handhelds could make for more direct collaboration than large lectures. Advantages of handhelds over laptops are less obvious here than in classroom contexts but it’s easy to think of fieldwork situations in which learners could collaborate with experts from just about anywhere there is a wireless connection. Immediate access to learning materials at almost any moment.

And podcasting. While podcasting got a big boost when iTunes began podcast support, there’s a lot which could be done to improve podcasting and podcast management. As iPod media devices, Touch handhelds have good playback features already. But there could be so much more in terms of interacting with (multimedia) content. Transcripts, tags, associated slides, audio comments, fast-speed playback, text notes, video responses, links, cross-references, playback statistics, waveform-based navigation…

Podcasting can still become big.  It’s now a “household concept” but it’s not as mainstream nor as life-changing as many hoped it’d become, back in 2005. I’m not really forecasting anything but I can envision contexts in which enhance podcasting feautres could make our lives easier. Especially in schools.

Education in general (and university education in particular) may be the context where podcasting’s potential is most likely to be realized. Though the technological basis for podcasting is quite general in scope (RSS enclosures, podcatching software, etc.), podcasting often feels like an educational solution, first and foremost.

A lot has been said about educational uses of podcasting. Early reports showed some promising results with those teachers who were willing to think creatively about the technology. I personally enjoyed a number of advantages of podcasting in my own courses, including several imponderables. Software packages meant for lecturecasts (podcast lectures) already exist. Apple’s own iTunes U is specifically geared toward university education using podcasts.

But there’s still something missing. Not just for podcasts. For handheld “educational technology.”
Momentum? Possibly. Where would it come from, though?

Killer devices? Apple already pushes its own devices (including the iPod touch) for “Mobile Learning.”

Cool apps? Haven’t really looked at the Web apps but it seems likely that some of them can already lead to epiphanies and “teaching moments.” Not to mention that tons of excellent learning software will surely come out of Cocoa Touch development.

Funding? My feeling is that apart from providing financial support for user-driven and development projects, “educational technology” monies are often spent unwisely. The idea isn’t to spend money but to “unleash the potential” of learners and teachers.

Motivation? Many learners and teachers are ready and it would be absurd to force anyone to become enthusiastic about a specific tool or technology.

My guess is that the main thing we need to make “mobile learning” a reality is to take a step back and look at what is already possible. Then look at what can become possible. And just start playing around with ideas and tools.

Learning is a component of playfulness.

Creative Inquiry

This should be interesting. My proposal for a session at the Spirit of Inquiry conference has been accepted.

Here is the description which should appear in the conference program:

Free, Open, Flexible: Rethinking Learning Materials Online
Alexandre Enkerli, Lecturer, Department of Sociology and Anthropology, Concordia University

Considered as a whole, learning materials such as textbooks and lecture notes constitute the “shoulders of giants” on which learners and teachers stand. In this session, academic publishers, instructors, librarians, and administrators are all invited to rethink learning materials through their own experiences with online technologies. A short, informal report on the principal presenter’s experience with podcasting and other online applications will be followed by a facilitated discussion. This session will pay special attention to issues of open access, academic freedom, and flexible strategies for learning and teaching. Together, session participants will construct a new understanding of the implications linking technological changes to the use of learning materials online.

My views are quite close to those of Richard Baraniuk of Rice University’s Connexions project providing open access to learning materials. Discussions of Open Access tend to focus on research articles published in peer-reviewed academic journals but this session will focus on pedagogical uses of online content, including podcasts, lecture notes, and textbooks.

I do hope that people from the publishing and “knowledge management” side of the equation will be present.

Zune Debacle: Worse Than Expected

Microsoft’s Zune media player is out:

BBC NEWS | Technology | Zune goes head to head with iPod

We already knew the sharing feature was crippled, even for non-DRMed user-created files and that Microsoft’s own “Plays for Sure” DRM will not play on the Zune. The Zune is crippled in other important respects.

  • Doesn’t use Windows Media Player.
  • No podcasting support.
  • The Zune software doesn’t allow for sharing between computers (the way iTunes does).
  • No PDA features (not even the iPod’s calendar and contacts).
  • Apparently no recording feature.
  • Apparently no add-ons.
  • Some music studios are asking for a share of the profits on unit sales, even though the device could be used with non-studio content.
  • The store’s “point system” is even more confusing than it first seemed. (A song is worth 79 points, costing $0.99, the minimum number of points is rather high…)

Actually, I just read Duke University’s report on their early iPod initiative. Since that report, the iPod has improved a lot and several features and services are especially useful for educational or academic use. Podcasting support in iTunes and iTunes U is far from perfect but makes the iPod a very desirable device for course-related use. With the help of an inexpensive add-on , the latest iPods can record in much higher quality audio than the version Duke had for its iPod initiative. Since recording was the most appreciated feature through that initiative, the iPod is a much better academic tool now than it was at the time of the Duke initiative. In fact, my iRiver H120 lacks many of the feature expected from the latest generation of media player but has proven an extremely valuable tool for academic purposes due to its recording abilities and the bookmarking features of the Rockbox firmware (ideal for podcasts).
Microsoft Zune’s goes in the opposite direction. No podcasting features, apparently no support for recording.

Too little, too late.

Podcasting Profs

My good friend Philippe Lemay is being interviewed by national media about his newfangled podcast-teaching methods. Here’s a short summary (in French):

Quand le prof vit aux îles de la Madeleine

Thanks in part to podcasting (and ProfCast), Philippe can teach in Montreal from his home in the Magdalen Islands. The implications are rather profound, especially for “remote regions” («régions éloignées»), the economic development of which often becomes politically significant. Granted, such solutions aren’t typically for just everyone and relying on technology for social change is often a risky proposition. But technology does bring hope to a lot of people.

Early October Quickies

Actually, they’re more like late September links, but still…

Is that Disparate enough for you? 😉

iRiver H120 (Digital Audio Jukebox)

Recently purchased a brand new iRiver H120 with remote control on eBay from OutletMP3. Paid 132.50$ plus 18$ shipping. Also purchased a 3-year warranty through SquareTrade for 16$.
Item arrived as described, with both the European power adapter (in the original box) and a North American power adapter (in the shipping box). The remote control is included in the package but is outside of the original box. OutletMP3 sells those iRiver H120 devices with or without remote control (usually at about the same price).
Yes. “Would do business with OutletMP3 again.” (As it turns out, they sell iriver products quite frequently on eBay and they have an eBay store with “Buy It Now” iRiver H120 devices without remote for 150$ each.)
The best things about this device are its recording features. Those iRiver H1x0 models can record uncompressed sound in WAV format at 16bit with a sampling rate of 48 kHz (so-called “DAT quality”), 44.1 kHz (so-called “CD-quality”), or lower (“FM-quality,” “voice quality”). It also records directly to MP3 files (with the official firmware) in a variety of encoding settings (up to 320 kbps). It has an internal microphone for voice dictation as well as an input for external microphone, analog line in, or optical in.
The box includes a surprisingly decent lavaliere-style monophonic microphone. Not an excellent microphone in any way but clearly better than one might expect (though Laith Ulaby had told me that this microphone was decent).

In terms of operation, the unit has some strengths. The overall interface is much less convenient than that of the iPod, say, but the battery lasts longer than most iPods (for playback). The iRiver H120’s remote has a small LCD screen which shows enough information for most needs making it possible for me to keep the H120 in my pant pocket and operate the device with the remote. While, among portable players, only the iPod has native support for AAC and lossless formats, iRiver players support Ogg Vorbis and WMA. Haven’t done anything in Ogg format yet but it might be an interesting option (though it does make files less compatible with other players).

Apart from navigation and interface, the main differences with my previous iPod 2G have to do with iTunes integration. The iPod‘s synchronization with iTunes made it rather convenient to create and update playlists or to transfer podcasts. iRiver’s models may not be used in the same fashion. However, the iRiver H120 can in fact be used with iTunes through a plugin meant for Archos players. However, this plugin seems to have some problems with a few files (probably because of invalid characters like ‘/’ and ‘:’ in filenames), generates non-working playlists on Mac OS X, and puts all filed in an “Artist/Album” hierarchy which makes iRiver navigation more complicated.

What surprised me somewhat was that the H120, a USB 2.0 device, works perfectly well with my old iBook (Dual USB) which only has USB 1.1 ports. No need for special drivers and the device then works pretty much like a (20GB) USB drive. Since the iRiver H120 works as a USB drive, it’s easy to transfer files to and from the device (contrary to the iPod which makes somewhat more difficult). All audio files can be put at the root level on the iRiver and audio recordings made on the iRiver are in the “RECORD” folder at the root level of the drive. While the iBook’s USB 1.1 ports are much slower than USB 2.0 ones, they do the job well enough for my needs. (Will be going back to my entry-level emachines H3070 in a few days.) A 400 MB file recorded on the iRiver (about 40 minutes of 16 bit stereo sound at 44.1 kHz) transferred to the iBook through USB 1.1 in less than ten minutes. Slow, but bearable. My old iPod used a Firewire 400 (aka IEEE 1394 or i.Link) connection which is about the same speed as USB 2.0 in most conditions. My entry-level emachines desktop has both USB 2.0 and Firewire 400 ports (thanks to an inexpensive Firewire card).

Was thinking about putting Rockbox on the H120 but SquareTrade tells me that it may void their warranty, which would be an inconvenient. The Rockbox has some neat features and seems safe enough to use on “production machines,” but its features aren’t that compelling for me at this point.
The H120 has a radio (FM) tuner, which could be useful to some people but isn’t really a compelling feature for me. Haven’t listen to much radio in the past several years. Podcasts are soooo much better!

Speaking of podcasts… One of my reasons for purchasing this machine (instead of a more recent iPod) was the ease of recording. This is clearly not a professional recording device but the sound quality seems quite decent for my needs at this point. Should be using it to record lectures and distribute them as podcasts or “lecturecasts” (yeah, ugly name, sorry!). In my mind, educational podcasting can supplement lectures quite nicely. Have been to a few workshops and presentations on technology use in teaching and most people seem to agree that technology is no replacement for good pedagogy but that good pedagogy can be supplemented and complemented (if not complimented!) by interesting tools. Had been thinking about a recording iPod to integrate podcasts with course material. It would have been quite useful, especially in connection with iLife and iWork. But an iPod 5G (with video) is already much more expensive than my iRiver H120 and the add-ons to enable 44.1 kHz / 16 bit recording on the iPod are only now getting to market at a price almost half that of my brand new iRiver H120. Plus, though the iPod is well-integrated with iTunes on Windows, iLife and iWork applications are only available on Mac OS X 10.4 and, thus, will not run on the entry-level emachines H3070 which will become my primary machine again in a few days.
In other words, my ideal podcasting/lecturecasting solution is out of my reach at this point. And contrary to tenure-track faculty, lecturers and adjunct faculty get no technology budget for their own use.
Ah, well…

Still, my iRiver H120 will work fine as a recorder. Already did a few essays with voice and environmental sounds. The lavaliere microphone was quite convenient to record myself while taking a walk which sounds like an unusual activity but was in fact quite relaxing and rather pleasant. In terms of environmental sounds, the same microphone picked up a number of bird songs (as well as fan noises).
Among the things that distinguish the H120 from a professional recorder is the lack of a proper calibration mechanism. It’s not possible to adjust the recording levels of the two channels independently and it’s even not possible to adjust volume during recording. (There’s a guide offering some guidance on how to work within those constraints.) Quite unsurprisingly (for what is mostly an MP3 player) but also making the device less of a professional device, its jacks are 3.5 mm “stereo mini-plugs” (instead of, say, XLR jacks). For that matter, the iRiver H120 compares favourably to several comparably-priced MiniDisc recorders, even Hi-MD models. Did field research with a used ATRAC 4.0 MiniDisc recorder. That setup worked somewhat adequately but this iRiver H120 is much of an improvement for me.

Got a few pet peeves about the iRiver H120. For instance, it has no actual clock so recorded files do not carry a timestamp. A minor quibble, of course, but it would have been useful. The overall navigation is as awkward as that of my first MP3 device, the RioVolt (which also used iRiver firmware). One navigational issue is that navigating up and down in the folder hierarchy is done through the stop and play buttons instead of, say, using one of the three jog switches on the remote. Some functions only work when the device is stopped while others work while it’s playing. Switching from hard-disk playing to recording or to FM is a bit awkward and cumbersome. The unit takes a while to turn on and doesn’t really have a convenient sleep mode. While it is possible to resume playing on a track that has been stopped, this feature seems not to work every time. Fast forwarding rate (“scan speed”) is set in a menu instead of being dynamic as on the iPod. The device doesn’t support ratings or, really, descriptions (although Rockbox might be able to support those).

Also got a few well-appreciated features, apart from those stated above. The EQ and SRS presets are appropriate and relatively easy to use. Contrary to the iPod 2G it is possible to play files at a higher rate (increasing the “playback speed”) making it possible to listen to voice at a higher speech rate (and higher frequency). It’s also possible to delete files directly from the device.

At any rate, that’s already a long entry and experience with my H120 will probably push me to write more about the device.

Feel free to comment or send questions through email.

Lecturecasts (Podcast Lectures, Lecture Podcasts)

UPDATE: Purchased an iRiver H120 jukebox/recorder.

Was commenting on Tama Leaver‘s post about watching his own lecture videos on a fifth-generation iPod. There’s a lot of room for experimentation with these methods and technologies.

Apple is well-positioned in this sphere, actually. Its iLife and iWork suites can integrate content in different formats, some of which might actually work on the iPod (Keynote to Quicktime H.264, GarageBand to AAC enhanced podcast). Furthermore, Apple has this iTunes U project for hosted and protected podcast content. Not to mention the obvious point about Apple’s iPod success. Don’t have the necessary material to try it out but it should be relatively simple to create full-featured lecture podcasts using these tools. In fact, there’s already a product out meant to simply this integration (can’t try it out myself, unfortunately).
With at least three microphones for iPod 5G coming out Real Soon Now (XtremeMac’s MicroMemo, Belkin’s TuneTalk, and Griffin’s iTalkPro), life can become quite fun indeed for those of us who’d like to “lecturecast.” It’s an even better time to turn to academic podcasting with so many podcasting projects springing up at such diverse institutions as IUSB, Duke, UdeM, Brandeis, and IUB. The open-source course management system Moodle now supports podcasts. So does Sakai, the free/open knowledge management project. Of course, educational podcasting isn’t new. But it’s gaining steam.

Performance and Identity in Podcasting

Duke Podcasting Symposium :: September 27 – 28, 2005
Didn't watch the fine webcast yet but it sounds interesting.
