Speaking about Audio

In this week's class, we discussed the effectiveness of using audio narration with images rather than using images and printed text. This is supposed to help prevent cognitive overload where too much information is being processed through the visual/pictoral channel. We did not go in great depth about it, but I wonder if this suggested rule applies more to e-Learning courses that do not often change. I work in a retail environment and our content is constantly being updated. Sometimes we've gotten audio recorded and the project is ready to roll out the door, and the entire concept changes mid-stream. This involves re-recording and re-coding, since typically you should include a close-captioning option. The majority of our online courses do not have audio, but some of our courses that are created in Adobe Presenter do have audio attached because it's so easy to include it.

Is there a happy medium? Or is it something that designers and clients determine on a case-by-case basis?

I Said It!

I was having a conversation with our director today and I casually used the phrase "cognitive overload" in a sentence. It just flew out of my mouth, and my hand flew to my stunned face as though I had just uttered an expletive. She was pleased to discover that school is paying off. She insisted that I share the news in my blog.

Consider it done!

Speaking of Madeline Hunter

We weren't speaking of Dr. Hunter, but I thought I'd use this title as a hook to lead you into this week's blog posting. In class last week, we discussed the importance of placing corresponding text and graphics near each other. This helps the mind create connections between words and pictures and increases the transfer of knowledge. I'm oversimplifying the point a bit, but I'm using it as a set-up to get back to Madeline Hunter.

When I read this chapter, my mind reeled back in time to the early 1990s when I was a young English major who planned to teach at the secondary level. One of my undergraduate classes focused on Madeline Hunter's 1982 book Mastery Teaching, and I remembered a discussion of how a teacher can create relationships by the way words are written on the chalkboard. I dug out my copy of Mastery Teaching and found a chapter called "Teaching to Both Halves of the Brain." In this chapter, Dr. Hunter discusses how teachers can use chalkboards to indicate relationships based on their position on the chalkboard. If a teacher writes the word NIXON above the word FORD, the student can infer that NIXON comes before FORD. But if the teacher wrote NIXON next to the word FORD, the student might infer that the teacher is drawing some kind of parallel between the two. Dr. Hunter closes this section of the chapter by saying,
"When we are aware of the power of position in space to suggest relationships, we avoid placing items on the chalkboard in a haphazard fashion or where there happens to be space. We place each item deliberately so its position indicates its relationship to other material on the chalkboard (causal, oppositional, numerical, comparative, categorical, etc.)" (p. 41).
I saw immediate parallels between a chalkboard and an e-Learning screen. The way we position items on a screen indicates a relationship, whether it's one or more textual concepts, corresponding text and graphics, or instructions and a practice exercise.

I love it when I can tie new learning back to previous learning!

Animation Time, Come On!

For this week's class, I had the opportunity to create my first animated GIF. The instructions suggested we use a tool called GIMP, but I didn't feel that I had sufficient time to become familiar with a different software package. I toyed with the idea of using Photoshop or Fireworks, and ultimately decided on Fireworks. I found a great tutorial to help me get started.

I used a sprite sheet found on the ShyGuy Kingdom site. Once I found a sprite sheet that had a good sequence of events, creating the animated GIF took very little time at all in Fireworks. I selected the graphics I needed from the sprite sheet using a rectangular selection tool, copied them into frames in Fireworks, and optimized the file as an animated GIF.

I'm quite proud of the little thing, but I can't post it to show you. Apparently, Blogger.com is having problems uploading images right now.

Getting Around

Our most recent class topic was Learner Control; specifically, how navigation schemes can help or hinder learning. Not only do poor metacognitive skills cause learners to make poor choices, but poor navigation can achieve the same result. If the learner doesn't know where to go next, he or she might just close out of the course and never come back if the experience was frustrating enough. One of the key reasons that some learners do not complete online learning is because of technological issues. This could be due to a variety of reasons: the course froze up; the data didn't transmit properly; or the navigation wasn't clear enough. An easy way to ensure clear navigation in an e-Learning course is to use a program such as FlashForm to help you build a template. It includes many of these things.

On a side note, I did a post for our wiki on Mystery Meat Navigation. This is a subject close to my heart because our department made an ill-advised move a few years ago and designed our website with a classic example of mystery meat navigation. Users had to click on unlabeled images to find out how to navigate through our site. It was a resounding flop and created a good deal of ill will that it took us over a year to resolve. We went back to a more standard navigational format within a year, but I've kept a screen print of the problematic navigation on my cubicle wall ever since as a reminder to keep our users in mind. It's not hard to see the allure of navigational styles where the user navigates through a series of images and mouseover menus. It is cool at a conceptual, "gee whiz" kind of level, but if it doesn't help users navigate, it's a lot of work for nothing. My favorite example of MMN (I think it deserves its own acronym) is the web site of a certain restaurant famous for its delicious burritos. It's better than it used to be, but when you load the site, you get a lone image in the upper left-hand corner. Hint: You click on that image to display the navigation. :-)
