No time to sync!

Do you ever have one of those days when you just don't have time to sync, and all you need to do is get one or two documents over to your desktop? I certainly have. Here are two tools that I've found useful in alleviating this problem (especially in working with a classroom of kids):

- The USB plus SD card - This SD card folds in half and goes into your USB port, doubling as a USB drive. Just pop it in your handheld, copy over a file, and pop it in your desktop or laptop. I don't know how I lived without this. :)

- IrDa (infrared) adapter- This a little inexpensive USB device that adds infrared capabilities to your desktop or laptop. Then you can just beam a document from your handheld to your desktop or laptop (or vice versa). Very convenient.

I love technology

Wow....I am really getting into the potential of video and tools like screencasting to differentiate instruction.

In my own work providing professional development for teachers, I struggle with how to differentiate my workshops. In most groups, some people like the pace of being led through how to do something and then having some time to try it on their own. But I also usually have a handful of people who would prefer a much quicker overview and then more time to explore on their own. And I often have a few people who would like a slower walk-through and a lot more hand-holding as they try it on their own.

This is a lot like the classrooms I've taught in. With 30+ kids, we all see many different learning styles. Add on to that different native languages, varying degrees of background knowledge, different reading levels, etc.... and well, that's why differentiated instruction is a popular idea.

The problem is that with one teacher and 30+ learners, it's tough to differentiate. That's where technology comes in! With screencasting or other types of video or interactive materials, it's possible to have a library of resources to draw on to meet different learners' needs.

I'm going to be trying this out in some upcoming workshops about podcasting. In addition to the workshop, participants will get (hopefully....if this experiment pans out!) a CD with mini-lessons on various parts of podcasting software. The idea is that you can get "just in time" help on something when you need it. Or if the video tutorials don't match your learning style, you can use printed instructions or the regular old analog version of me!

Another great use for this technology is distance learning. Face-to-face workshops are great, but if you can't travel to Hattiesburg, Miami, Greensboro, Spokane, Austin, or any of the many other cities I tour, how about a CD with the basics? (Maybe some day, I'll just stay home and send a CD instead.:)

Stay tuned for how this all works out, but I'm feeling very excited about the potential. Beyond staff development, this is a great way to teach math, vocabulary, or lots of other things.

Audio blogging sites

As reported earlier, Audioblogger is discontinuing its wonderful service, and so we've been evaluating other similar services to see if there is a good replacement out there. So far, the winner is GabCast.

Gabcast has a few features that I liked even better than Audioblogger. Most notably, you call a toll-free 800 number to use the service, making it completely free. They also offer automatic RSS feeds, making this a viable solution for low-end podcasting.

You can hear an example of this in the previous post. This recording was made by just calling an 800 #, entering my channel # and password, and talking! Pretty slick. They even have a nice tool that automatically posts the audio posts to your blog (as shown here). There is a conference call option that sounds pretty neat. Stay tuned for a test of that.

If you know of other (preferrably free) audio blogging sites that have good features, post them here. Thanks!

Audio ebooks

There are getting to be a good number of sites offering free audio books now. Here are a few:
Spoken Wikipedia is also a good source for spoken audio files.

Also make sure to check out your local public library for additional audio ebooks.

    Ebooks

    A just-released study by The Survey of Academic Libraries, a benchmarking report published by Primary Research Group Inc. says that "Spending on electronic books by academic libraries has reached a cumulative total of 11% of their spending on print books, and will reach 20% by 2011."

    Wow, that's interesting. It would be great to see schools and especially textbook publishers follow this lead and make more core curriculum ebooks available for our students.

    SD cards and Tungsten E2s

    Now that larger SD cards are now available (and relatively expensive), it may be worth noting that the Tungsten E2s do not support SD cards larger than 1 GB. Hope this helps some of you.

    Sad news

    I just heard that Audioblogger, one of my favorite services for posting audio directly from a phone (and which I just blogged about earlier today) is going away. :( They have suggested several other similar services. I'll check them out over the next week or so and let you know how they look.

    Mobipocket Creator now free

    I've been raving about Mobipocket as an ebook platform for a while now, and now the tool to create Mobipocket ebooks is free!

    If you want to see an example of some of things you can do with Mobipocket, check out our ebooks on the Constitution.

    Podcasts to your cell phone

    Here's an interesting article in Wired about getting podcasts right on a cell phone. There aren't a lot of phones that are set up for this now (and they are expensive), but this is something that I think will get cheaper and more ubiquitous in the near future.

    I've thought a lot about cell phones as a kind of future computer that could be used for communicating with parents, sending assignments to kids, keeping digitial portfolios, making and receiving podcasts, etc. Applications like AudioBlogger already let let you post a digital audio file directly to web page from any phone with no computer required for free. What could be easier than that?

    In order to reach its potential to revolutionize education, technology needs to be simple, easy to use, cheap, and ubiquitous. Phones meet all these criteria.

    AvantGo and RSS

    From when I first started using handhelds years ago, one of my favorite applications has always been AvantGo. It lets me download the newspaper every morning and subscribe to numerous other publications and web sites, all free of change. Now AvantGo also supports RSS feeds, making it a great tool for keeping up on all the blogs I like to read.

    Portable Media Expo - Installment 3 (final one)

    This is my last post about the Podcast and Portable Media Expo. A great little trick that was shared at a session called "Podcasting the Written Word" was the "clicker trick." We all make flubs when we're recording audio. Generally, we just pick up with the sentence and clean it up in editing. If you use a clicker to signal after you've flubbed though, it makes editing a lot easier, because you can see your mistakes (represented by two spiked lines). Here's what it looks like:

    (Believe it or not, I have a clicker that a teacher gave me, suggesting I use it as a way to quiet and "refocus" workshop participants. Luckily for everyone in my workshops, I decided not to use it for that purpose.)

    Another good recording tip from this session was not to re-record too many times to try to get the "perfect" take. Generally, your first take will be your most enthusiastic and best.

    Saturday's key note was from Drew Baron of Rocketboom, a daily video blog. He casually mentioned that Rocketboom makes their video available in 9 different file formats. The necessity for this seems like a huge problem. This needs to be easier for end users. I'm all for having choices, but there are real benefits to some level of standardization.

    I also attended a session called "The Secret Lives of MP3 Files" by Doug Kaye that covered a lot of good technical details on file preparation. Here were a few useful general guidelines he shared:

    • Record as wav or aiff using a 44.1 khz sample rate (needs to be a multiple of 44.1 khz for maximum compatibility)

    • In general, encode at 64 kbps; may want to use higher bit rates for stereo

    • For recordings that are mostly speech, before mixing down to mono, make L and R channels inidentical (copy and paste L onto R) to maximize encoding efficiency

    • In mastering, do peak normalization and RMS normalization; also presented was a new free tool called The Levelator that adjusts the levels of various clips within your podcast to even out the levels. According to their web site, "It's not a compressor, normalizer or limiter although it contains all three." I haven't used this yet, but look forward to trying it.

    I enjoyed this conference and hope you all enjoyed reading about it.

    Portable Media Expo - Installment 2

    Continuing my report from the Podcast and Portable Media Expo, at a session called "Succesful Podcasting in Education at the University Level," a panel of folks from higher ed presented about how they're using podcasting.

    Dr. Michael Schmidt from the Medical University of South Carolina talked about how they justified the use of podcasting for mandatory compliance training. By delivering the training on mobile media players, he said that they were able to justify the cost of the players over just a few weeks of use in terms of time saved for their busy professionals. [I think there is a lot of potential in delivering professsional development to administrators and educators in a similar way.] When asked about how attendance was verified, he said that their assessment techniques were competency-based and that participants had to have a 100% pass rate on the assessment. [This is a model K-12 education should look at. Competency-based assessment makes a lot more sense than our current model based on "seat time."]

    Another panelist talked about using podcasting to move from a classroom lecture format to a Socratic method. In this model, students are given a podcast with the class content in advance of class and are required to come to class prepared to discuss it.

    Several panelists said that rather than encouraging students to skip class, they thought podcasts made students more interested in classes and may even increase attendance as a result.

    A final discussion at this session revolved around access. While some imply that "digital natives" are ubiquitous now among the under-20 crowd, an audience member challenged that assertion. [This is a real issue for K-12 education. We can't assume that all students have devices and/or Internet access for home use, and it doesn't seem fair to ask that those students who don't stay after school to get access. I think that one great solution to this is providing learners with small inexpensive devices that are pre-loaded with the content they need.]

    The next session was presented by Rick Klau of FeedBurner. Mr. Klau presented a lot of very valuable information about RSS feeds and related technical topics. He began with some figures that were echoed by many other presenters at the conference - iTunes represents about 60% of the RSS subscription market, and the ratio of downloads to subscriptions is about 2-to-1. [This means that twice as many people click a link to an MP3 file to listen to an episode as those who subscribe to an RSS feed. This seems astounding. If this applies to you, check out RSS subscriptions; they're so convenient....although not universally easy to use. More on that in a subsequent post.]

    Klau talked a lot about terminology and standards. Clearly, podcasts in general and RSS feeds in particular are a lot harder to access and use than they should be. For one thing, Klau defined a "podcast" as the content AND the feed. (That being the case, it doesn't really make sense to talk about "downloading a podcast." The correct terminology would be downloading an episode. While this may seem like meaningless semantics, when new users are visiting podcast web pages, the lack of standard terminology, etc. makes it very confusing. If you have a podcast web page or blog, do your users a favor by making sure it's clear and easy to use. )

    He also talked about using a "browser-friendly" view of your XML feed. You may have clicked on some XML feed links and gotten something that looks like HTML. Other XML feeds links look very nice though. The difference is including styles sheets. Here's an example of what this looks like.

    Klau also talked about IE7 having a built-in RSS feed reader (something that Linux and Mac have had for a while). Maybe that will prompt more people use to use RSS.

    Stay tuned for links to the slides and audio from all these sessions as soon as they're available.
