Clouds *sighs*

I love visualisations, particularly wordy ones. I love how this nice little service produces charming word clouds. Here are the contents of my blog:



Cute, huh?

Today, a compliment

Well, I took it to be one, anyway. A student asked me if they have Daylight Savings Time in the Cook Islands. I kind of blinked and asked why I would be expected to know that, and he replied that I am a fount of knowledge and so it was worth a try. That was nice.

So then, I asked why he didn't just google it to find out. His answer? He's not very good at searching. He doesn't know what keywords to use, and, even if he takes a guess at the keywords, he doesn't know how to combine them or how to sift through the results he gets in order to find something that will be useful to him.

In this particular instance, he was trying to find the time in the Cook Islands based on a time in Aotearoa New Zealand, given one time when NZ is not in DST and one when it is. First of all, I explained how time zones worked and we figured out in our heads how the times related. Then, we confirmed it with a handy time zone converter.

I found one online.

This student had no idea how I found it.

So I tried to explain boolean searching. At this point, he started to have that hunted look that people get when they really, really wish I'd just shut up and let them continue on having no idea how to fix things. I am pretty much immune to that look now.

I started with some venn diagrams, as in this picture below:


He kind of got the point of this. It's using simple English conjunctions to connect search terms in a way that makes them form a combination. That's all good. But that doesn't really make much difference with the first problem - that of the lack of sensible keywords in the first place.

In the Daylight Savings question, I put in daylight savings Cook Islands as my keywords. I didn't even bother with boolean connectors, because I was pretty sure I would find a useful link on the first page. I asked the student what he would have put in, and he shrugged. He didn't even really know where to start with it.

I think I will, next week even, start working on this with my younger students. I am inspired, because, even though being the fount of knowledge is good, I'd rather be the facilitator of how to do it yourself.

Sherbet, or the fizzing taste of success

I like to think that cognitive dissonance is a little like sherbet. It fizzes on your tongue or in your mind and you find yourself having to adjust to the new ideas and tastes. I am also a bit of an opportunist. I would blame it on having a bit of crow in me, but we don't really have the crow archetype as such in Aotearoa.

Leaving aside my fondness for shiny things, I love to encourage moments of cognitive dissonance. The thing is, they take time to find and set up. Then the students take time to talk through what they've observed and come up with new explanations that are consistent with both their observations and the theory you and/or the text have provided. Today, I wished for a shortcut. I wish that sometimes, me saying "it just does" was enough of a reason for students to believe.
