Using Online Video in Class


L
anguage teachers have been using film and video in class as long as these media have been available. Lately, YouTube, videojug, Google Video, blip.tv and other Web 2.0 inspired, user-created content sites have appeared in the repertoire of language teachers with access to computers and the Internet in class.

Let's assume that most trained language teachers see the pedagogical merit, or potential, in such content, including variety, currency, and appeal to students as a familiar resource. At least four practical concerns quickly emerge when using online video:


Access
In planning on the use of online video in class (streamed at time of use, not previously saved as a local file), we make certain assumptions that we would not likely have made just a few years ago:
1. Continuous broadband (high-speed) Internet access (as opposed to occasional dial-up modem access).
2. Ubiquitous Internet access available at all learning locations via wired or wireless (WiFi) connections.
3. Computer hardware capable of playing compressed video (fast processor, sufficient RAM).
4. Appropriate media player software installed and configured to play Web video (e.g., Flash, QuickTime).



Quality
In order to host a tremendous number of videos, video sharing sites must further compress video files uploaded by users, sometimes appreciably degrading quality. Someone has said that the blurry quality of these videos makes them appear as if they are being viewed through Vaseline rubbed in your eyes. So image quality is an issue.

For language learners, this may blur the lip/sound correspondence that aids in comprehension.

The image on the left below is from the original, uncompressed video file (.dv). The image on the right is from YouTube, which shows only a little image degradation. This might be because I uploaded a large, high-quality version of the video to begin with (.mp4).



Original videos of lower quality might not fare so well, as with the popular Parkour video below.




Permanence
When you link to online content, you always run the risk of losing access to that content without warning if the owner moves or removes it. The ephemeral nature of popular user-generated video increases this risk. Contributors can remove their videos at any time.
To avoid this risk, you can capture some streaming media to locally saved files, access to which you control, but this raises ethical if not legal issues. Applications like iRecordMusic (Mac) or Freecorder, WM Recorder, or  Super MP3 Professional Recorder,  (PC) allow you to capture streaming audio and TubeSock (PC and Mac) captures streaming video. The free online tool KeepVid allows you to easily capture any streaming video in any browser.

Audio or video podcast versions of content, where available, are readily downloadable files that play locally from your computer and skirt the permanence and copyright issues.


Context
At many sites offering video content, a selected video is displayed in a busy and, to some, a confusing context of other content, links, and ads. Especially on sites of user-generated content, such as YouTube or videojug.com, some of this context may be offensive, inappropriate, or, at the least, distracting.

On many video sites the "Embed" information solves this problem by allowing you to display only the video of interest to you in your own context. By pasting that embed code into your own web page, blog, or wiki, you essentially strip this content from its originating context, allowing your students to focus on the video, as in the example below.

MLL Tech Tips-January 2008

Use Firefox not Safari for Nexis

The new LexisNexis search does not appear to work with the Safari web browser (on the Mac). Use Firefox instead.


Creating folders in the Group shared folders

If you log in to your class setup and add a folder to your class Group folder, your students will not be able to access files inside this folder until Rudy resets the permissions on the folder. After creating a new folder, let Rudy know.

you created it so he can fix the permissions.

Lobby TV Usage and Programming Survey

I lobbied for several years to get a large-screen TV in our lobby, believing that it would contribute to the linger phenomenon in that space, which in turn would contribute to the sense of community that students find here. We could, I argued, use such a TV for laptop-fed announcements and for cable TV content. Anything that keeps our students hanging out in our lobby, preferably speaking English, could contribute to the sense of value that they derive from their CELOP experience overall.


See the Comcast channel lineup for our combined packages.


Prices on flat-screen LCD and plasma screen have come down dramatically, allowing us to install a 42" plasma screen in the lobby last fall. It has been used primarily for announcements run from a laptop at the Front Desk. We now also have an HDTV digital cable feed from Comcast, a package that includes basic cable TV channels plus a special sports package giving us most international soccer games.

We need to devise a usage and programming policy of some sort (what to show and when). Please let me know what you think using this form, and I’ll report back on the results. In the meantime, the Front Desk will manage use of the screen, mostly continuing to display program announcements and perhaps experimenting with some news and soccer. (If you have concerns about its use during this period, please let me know.)

MLL Tech Tips-November 2007

What, another blog?

Yes, just what the world needed. Or at least our world. We need a better way to communicate news to the CELOP community regarding MLL issues specifically and technology issues generally. Read this blog to get updates that used to be distributed on printed MLL Updates newsletters (still archived on MLL Tutorials).

What can you do with this blog?
  1. Come here (mll-celop.blogspot.com) and read it. It will be updated throughout the semester.
  2. Use this feed address in your RSS reader, such as iGoogle, to get article titles automatically delivered to you:
    http://mll-celop.blogspot.com/feeds/posts/default
  3. Post comments (link below) to articles for all to see.
  4. All articles are automatically archived in reverse chronological order. See the Blog Archive on the right side of this page.
  5. Learn more about blogs and RSS feeds, including having your students use them for their writing.

New laptops and iPods!

The MLL has two new MacBooks and the two iPod Nanos that came free with them. Reserve these, and all other equipment, in the maroon binder in MLL office 251.

So, now we have the following portable equipment that you can reserve for use in your class:
5 Apple laptops (2 of which will also run Windows XP)
2 iPod Nanos
Speakers for laptops and iPods
4 projector carts with speakers (some with DVD and VHS players)
4 video cameras

Why iPods for the lab? Use them to bring digital audio into your classes outside the lab or smart classrooms. (A boombox still works for audio on CDs.) For example, if you want our students to do an activity involving an NPR program (or any audio), you could follow these steps:

  1. Reserve an iPod and speakers in the equipment check-out binder in 251.
  2. E-mail a link to the NPR story to John (or Rudy), who will put an MP3 file of the program on the iPod.
  3. In class, simply connect the iPod to the speakers, find your program on the iPod menu, and play.
If the iPod freezes up when trying to play a track, restart it by pressing the Menu key and enter key simultaneously for several seconds until the Apple icon appears.




A Better VPN Experience


Use Shimo instead of the Cisco VPN client to connect to B.U. It's faster and promises to stay connected. It adds a menu item to your top Finder menu.
