the one where I finally publish my thesis

So it’s been in progress for a long time. A long, long time. It’s been nearly done for some time as well. I completed (and passed) my oral exam on Nov. 30, and had some additional revisions to make before the thing could be considered officially complete. Now, it is. I present… A Case Study Using the Community of Inquiry Framework to Analyze Online Discussions in WordPress and Blackboard in a Graduate Course1...

discussion visualization with gephi

I've been playing around with gephi today, to see what I could come up with to display the discussion threads from my research data. Lots of manual data entry later, and I've got this: and this: WordPress sites are shown in red, Blackboard discussion forums in blue. So far, just a pretty picture, but I'll hopefully be able to coax out a diagram or two that shows the difference in interaction patterns between the two platforms....

discussion network visualization

I just put together some quick network maps for the online discussions from my thesis research data. Haven't done any analysis - just some purty pictures to see any at-a-glance differences: Both discussion platforms had about the same number of posts and responses, but the pattern of connections is markedly different for some reason...

aggregated metadata for online discussions

here's a quick look at the aggregated metadata for all of the online discussions I'm using in my thesis: About the same number of posts in each platform, with a bit more of a time-spread in the WordPress discussions, substantially longer posts in WordPress, about the same (non) use of images, more links in WordPress posts, and more attachments in Blackboard posts.

basic metadata analysis

Here's a quick pass at analyzing the basic metadata for the online discussions. I plotted a few calculated values (Excel pivot tables fracking ROCK, BTW...), to try to compare activity patterns. What's interesting in this graph is the average wordcount (green line) - low for the Blackboard discussion board threads (the left 5 items) and markedly higher for the 8 student blog (the right 8 items). The number of posts in each discussion (dark blue line) is relatively consistent across all discussions....

full online discussion metadata visualization

I've finally entered all of the metadata information for the online discussions I'm using in my thesis. This includes the person who posts something, the date, and the size of the post. I worked through my earlier visualization mockup, and wanted to try it with the full set of data. So, here's the Blackboard discussions (top image) and WordPress blog posts (bottom image): It's only the most basic of metadata, but already differences in activity patterns are becoming apparent....

on visualizing online discussions

For my MSc thesis research, I'm working with a bunch of data collected through online discussions during a blended course. Part of the discussions took place using Blackboard's discussion board feature, part took place on students' blogs. One of the things I need to do is to document how the discussions played out, to try and tease out any differences between the two venues. I'll be using the Community of Inquiry model to describe the social/teaching/cognitive components of posts, but I've been wanting to describe the flow of discussion as well....

some notes from weekend reading

wherein I repeatedly use "affect" instead of "effect." oops.

community of inquiry

When I started at the Teaching & Learning Centre, I knew a bit about what Randy Garrison was doing - he was the new Director of the TLC, and he'd been working on something called "[community of inquiry](" - but I didn't know too much more than that. I didn't pay it much attention, since it didn't overlap what I was doing very much. Years passed, and I'm now planning the research proposal for my MSc thesis....
