Announcing an official press release for the Winter South 2014 kickstarter project.
Please help me spread this far and wide to the appropriate media channels!
On Thursday, October 31, at AECT 2013 in Anaheim, I’ll be conducting a “round table” discussion/presentation about a manuscript I’ve written: “Direct Measurement of Learners’ Graphing Interactions for Automated Formative Assessment in a Digital Tablet Environment.” It’s a conceptualization of a digital graphing platform that can persist across informal and formal learning environments.
Here’s the abstract for the manuscript:
This methodological paper explores theoretical and practical foundations for the development of measurement instruments embedded in a tablet-based interactive digital graphing platform for use in unobtrusive automated formative assessment of learners’ performance when plotting and/or visualizing data as all or part of a learning task. Practical matters of data plotting and manipulation as formative performance assessment are addressed. Exemplary tasks are provided as a basis for further examination and discussion of identified practical matters. Modeling learners’ growth in graphing ability over time is explored in the context of experimental research of cognitive factors of graphing interactions.
I’ve also made the manuscript available as a whitepaper here on my website: ErlandsonBE_Direct-Measurement-Graphing-Interactions. Please feel free to read it and give me any constructive feedback you may have. Questions also welcomed! Let’s start a discussion…
As I was a walking home from the fitness studio late this morning, the rain was picking up again. There are several large puddles on the rather crooked sidewalk between the studio and my house. As I rounded the corner, over the din of the raindrops I heard this repetitive high pitched squeal, coupled with the occasional splash.
Into view comes a small girl, probably between the ages of three and five, covered from head to toe in a raincoat and galoshes. She’s several paces ahead of the rest of her family. She’s yelling (singing, really) over and over again, “I don’t want to get wet, I don’t want to get wet, I don’t want to get wet!” as she gallops from puddle to puddle. Finally, she notices me coming from the other direction and stops dead in her tracks. Rain dripping through the soaked dark brown locks protruding from either side of the hood of her jacket, she makes eye contact. I flash her a quick smile to let her know I’m harmless, and then she cracks one of the most devious shit-eating-grins I’ve ever seen on a kid that age (even trumping my nephew Bennett!).
And then it was right back to puddle splashing and singing her refrain.
My faith in humanity got bumped up a notch today. Thanks, kiddo. Go in peace and never, ever stop splashing.
Last weekend, I spent some time in Berkeley, and on Saturday I had a chance to see the UC Botanical Garden. This is one of many shots I took.

Hope you enjoy them!
I found myself down at Carmel Beach last evening to hang out with a buddy of mine (and his two cool pooches) at the beach to watch the sun and waves, bitch about the week, and talk science.
Eventually the sun went down, my buddy went home, and I stuck around to get some post-sunset surf shots. I love the effect of slow shutter speeds on the waves. Using a circular polarizer adds to the glow of the waves, I think.
In this particular shot, I kept trying to get the timing just right (with about a 4 second exposure, if I remember correctly) to get a good spray off the rock that you can see there. I think this one came out pretty well…
I’ve been enjoying exploring the increased flexibility of my new Canon 7D, and although I like the fact that the new lens I got has image stabilization — allowing for on-the-fly closeups like this bee — I’ve come to realize that it’s causing me to forgo the tripod more than I should. I’m mostly happy with this shot, but I know it could be so much better with a tripod. The sad thing is, I had my tripod with me, strapped to my awesome new slingbag, but I just got caught up in the moment.
Ahh, well. Next time…
I’ve decided that I’m tired of maintaining my own site that I’ve built from scratch.
It’s time to switch over to wordpress for good, methinks. I’ll be updating the look and feel over the next few weeks and integrating a lot of content from all my other web and social media presences.
