Here comes Linux, part 1

Here comes Linux, part 1

“Are you kidding me???” Dee shouted in disbelief.

I’d just told her that I–a faithful Mac user for the last twenty years–had ordered a Dell Mini 10v.

“Are you KIDDING ME??? she shouted again, thinking perhaps that I hadn’t heard her the first time.

“Yeah, I know…” I went on to explain that I’m not giving up the MacbookPro. And I’m definitely not using Windows (no offense). I’ve been looking for a decent portable on which to install Linux Mint, and after passing on the idea of a Lenovo ThinkPad (high quality, but a little higher-priced especially for a second machine), I fell for the “$100 off, free shipping” email that I’d gotten for the Dell.

This is more than just Black Friday extravagance. I’ve been intrigued by the idea of working with Linux on a laptop for a number of years now, ever since Mark Pilgrim famously made his own switch from the Mac three years ago. His reasons included Apple’s proprietary file-formatting and Digital Rights Management (DRM) lockdowns that make playing by their rules occasionally difficult. The hardware, although of high-quality, is known for being expensive, placing it out-of-reach for many students, and a number of teachers. The question became, is it reasonable for me, as an educational technologist to run most, if not all, of my digital life using Free / Open Source Software?

In addition to other topics being discussed here, I’ll be covering the journey here once the new machine arrives in a couple of weeks. For now, though, I’m anticipating using the following software:

Mac Linux
Operating System OS 10.6.2 Linux Mint 8
Browser Safari, Firefox Firefox (pre-installed w/LinuxMint)
Mail client Apple’s Mail.app Mozilla’s Thunderbird (pre-installed w/LinuxMint)
Chat client iChat, Adium, Skype Pidgin (pre-installed w/LinuxMint)
Web development client Panic’s Coda Quanta Plus?
Calendar program iCal Mozilla’s Lightning?
Text editor emacs, BBEdit emacs (must be installed using apt-get), gedit (pre-installed w/LinuxMint)
Office apps Word, Excel, PowerPoint Open Office? (pre-installed w/LinuxMint)
Music playing iTunes Pick one
Music editing Garage Band, Amadeus, Audacity Audacity
Image Processing iPhoto, Photoshop Elements, Acorn, Graphic Converter GIMP

Any suggestions out there? Let me know!

Gedanken Me This: Why not open up your classroom content?

GEDANKEN ME THIS: Why not open up your classroom content?

In the process of slowly putting aspects of my face-to-face teaching up onto the Web, I’ve been asked this single question more than any other:

“Can I get a copy of your PowerPoint slides?”

The presentation slides that I use to structure my classroom discussions contain just about what you’d expect from a carefully considered deck. I’ve got graphics and diagrams, important definitions, sample problems that I want to go over with the students, and an impressive lack of the dreaded “bullet points.” I’m a faithful acolyte of Garr Reynolds (Presentation Zen: Simple Ideas on Presentation Design and Delivery is amazing) and Nancy Duarte (buy slide:ology: The Art and Science of Creating Great Presentations
NOW), and I have enough experience to know that the slides are not my presentation–I’m the presentation; the slides are just a tool that make it easier for me to present to a larger number of people.

One of the main reasons I began using presentation software (which can include Microsoft’s PowerPoint, Apple’s Keynote, OpenOffice’s Impress, Google’s Docs, etc.) was to make my “lecture notes,” graphics, and material covered in class available to students who had been absent, or for those who just wanted copies to review with. I made PDF printouts of the slides available for download on the course website, but was reluctant to share the actual slides themselves. Because… well, those are MY slides.

I’ve been working on MY slides for YEARS now, refining them a little almost every time I use them. I feel suprisingly attached to those slides, and protective, and I’m not alone in this. At least two of my colleagues–one where I currently teach, and one at a former school–feel exactly the same way. The colleague in Northern California is about as hybrid as it gets: this guy–my best friend Aaron, and partner in edtech crime–actually records video of his lectures every day, and posts it on the Internet for his students to see.

But you can’t get him to share his slides with you to save your life. It’s funny.

So here’s your Gedanken for the day. Why NOT share your slides?

Seriously. Why not? Why not share your slides, and your handouts, and just about everything else that you use in your class? What do you think is going to happen if you do?

In software development, this idea of opening up your source code for the world to see (and for others to potentially collaborate on) is called “open sourcing,” and we teachers have been doing this for years. “Steal from the best” is the advice my mentor teacher gave to me, inviting me to watch and learn from others, and freely incorporate whatever ideas I thought would assist my own development as an educator. We do this informally (“Hey, how are YOU teaching “Macbeth” this year?”), formally (“We need to sit down to plan this next unit together…”), and institutionally (“Richard, how’d you like to work with a student teacher this semester?”). And frankly, all this sharing? I love that about our profession. So I don’t know why I’m so protective of my course materials.

In discussing this, my friends and I came up with lots of great pretend-excuses.

  1. “I worked hard on these slides–I’m not just going to give them away.”
  2. “What if someone uses my slides… ‘incorrectly’?”
  3. “It’s the responsibility of every teacher to create their own presentations.”
  4. “I want students to have to copy down the information by hand–that way, they’ll learn better.”

I’m not convinced that any of these points stands up to much scrutiny, though. In the end, making slides available to students and colleagues enhances your ability to communicate with them, and does absolutely no harm to you or your teaching that I can think of.

Ask yourself this question: if you were to die tomorrow, would you prefer that your slides pass into the afterlife with you, or would you like them to be available for the potential benefit of others?

I’m not entirely comfortable with the idea yet myself, but… I’m opening up my class. Not EVERYTHING, of course. I can’t post online materials that I AM allowed to use in class under Fair Use doctrines of U.S. copyright law. I’m not going to publicly post students’ grades, or other materials to which I don’t think students should have free access (next week’s test comes to mind here).

But my syllabus? Of course! My grading policies? Sure? The handout and grading rubric for next week’s Independent Project. Yup. The schedule for the next unit? That only makes sense…

And my PowerPoint slides? Well… okay. I’m in.
