There's an old adage that says, "When you're up to your ass in alligators, it's difficult to remember that your purpose was to drain the swamp." This is where I've been for several months (i.e., up to my nose in developing and testing methods for teaching online courses). Now, I'm stepping back from it all for a moment or two and am attempting analyze what I have learned thus far.
The distance-learning instructional design model that I'm developing includes several technology-related variables. A key variable is the computer monitor screen. In my mind, for the distance-learner who wants to use the Internet as a path to learning, the computer monitor screen is the center of the universe.
Realizing this, the designer of a distance-learning experience should learn to "look through the eyes" of the learner and see what the learner sees on the computer monitor screen. With this vision, the challenge is to mix and match technologies in a way that will make the learning experience come alive for the distance-learner. This is what I call "blending."
For a long time, I created and maintained my own course website. However, after learning about a course management system (CMS) called HTML-eZ, I decided to use it in lieu of doing all of the website work myself. It's so "eZ" to use (sorry, no pun intended here) and so flexible that the switch to eZ was a no-brainer decision. If you're interested in learning about "eZ" click on the following link.

I use eZ as a combination course website/web portal. The key to making it work is hyperlinking. A student clicks on a course option in eZ and seamlessly goes to the learning experience needed at the moment. This is where the blending of technologies (i.e., the mix-and-match process) comes into play.
I use a variety of software programs to create distance-learning materials. For example, when I create streaming lecture discussions, I use PowerPoint to create the slide show. I then record a soundtrack (.wav file) that I insert into each slide. This approach enables each slide to stand alone which is important for playback.
Once I am satisified with the PowerPoint program, I import the PowerPoint file into Impatica for PowerPoint. Impatica then converts the PowerPoint file into a Flash file (.swf) that is embedded into an HTML page. Impatica uploads the HTML file to my web-host account. I then include the hyperlink in my course materials that the student accesses through eZ.
This process (PowerPoint + Soundtracks + Impatica) enables me to deliver archived streaming lecture discussions that can be viewed by students whether they are on a 56K dialup (or less) connection or a high-speed connection. For example, this approach solved the question of how to deliver streaming material to an AOL-level user. It works!
While eZ includes a "group pages" function that enables study group collaboration, I much prefer the richer user-experience provided by the Groove workspace. To to this, I modified my instructional design model to include more than one platform. This required that I "step outside the box" of my design and run parallel platforms. Once I accepted this idea, I decided to try running multiple platforms. The design model then looked like this:
eZ + Groove + Other Platforms
By "other platforms," I am referring to other technological capabilities. For example, on Jeroen Bekkers (Suite 75) weblog, Neil Finlayson talks about using "Skype" with Groove. I've had my students doing this for some time.
By combining Groove + Skype my students are doing essentially the same things that can be done through web-conferencing programs like WebEx or Live Meeting. The bottomline to this blending of technologies is powerful collaboration at a very cheap price. If you would like to learn more about Skype click on the following link.

While using multiple platforms works and definitely opens doors to a wide variety of learning experiences, this complicates things for the online learner in that the learner needs to switch between platforms. I keep looking to the power of hyperlinking for a solution.
One way that some of my students have been able to simplify the process is to use "GotoMy PC" as a way to make Groove a web-based program like eZ. This approach enables the whole distance-learning process to be web-based. The principal limitation to this approach is that in order to use "GotoMyPC," a student must have an always-on Internet connection such as cable or DSL. Not all students can afford this approach.
An alternative approach that I'm exploring is to access Groove through PopG's "Blended Groove." A student could simply click on a button on the eZ course page and access Groove in a seamless manner like any other element of the course material.
Now, my instructional design model is beginning to look something like this:
eZ + Groove + PopG + Skype + Other Platforms (through hyperlinks)
The power of this design is that the distance-learning experience can be rich and varied, synchronous or asynchronous, while placing an emphasis on collaboration. A student logs into the course website on eZ. Most course features can be accessed through the click of an option's button. Hyperlinking makes most of the process seamless.
Skype runs on each student's computer. Therefore, not all platforms can be hyperlinked.
I have done a lot of work to get to this point in developing my distance-learning model. It's now time to start writing about the model, my research findings, and possible implications for distance learning. With a little luck, I'll get a publication or two out of all this.
As always, I'm open to sharing what I've learned with others. Your comments and suggestions will be greatly appreciated.
