A post a day for 10 days?

I saw this post from Tina Zita (@tina_zita) on my Twitter feed this morning, and thought... 'it's almost exam time, can I do this?'

If I start small, maybe.

So... what did I learn today?  I finally learned how to use the spirometer.  I've been at this school for longer than my grade 12's have been alive (kids born the year I started at this school are in their first year of university now), and I've never used the thing. Seriously, I could have searched Youtube for an instructional video - oh look, I found one!

But in the past, I've used other techniques to measure lung volumes, mostly involving balloons and mathematical approximations of volume.  Maybe tomorrow I can post about how well it worked for my students...

The good on Twitter...

There is a lot of negativity on Twitter and other social media platforms right now, thanks to the change of power in the US, and controversial appointments to high-level government positions.  This will not be a political rant... I am choosing to focus, instead, on the good things I've seen on Twitter today. Very useful, interesting site to promote problem solving, communication & critical thinking. #mathed https://t.co/YeN866cTzy @Jstevens009 pic.twitter.com/uvHBIA6eq8 — Jim Cash (@cashjim) January 23, 2017 This tweet from @cashjim led me to  wouldyourathermath.com , and though I haven't taught mathematics in years, as a science teacher, mathematics still crops up in some topics so I thought I'd explore. In particular, I like this one on statistics and thought before I used it with students, maybe I should review (or actually learn for the first time) what a boxplot is.  I did a statistics course in my third year at university, but what I r...

Has it been 10 days yet?

Yup.  I just counted from my first post, and it was on January 16, making today day 10. I missed a couple of days - both times I had begun writing, but didn't finish or didn't publish the draft - but I also double posted a couple of times, to try and catch up. Still, this is post number 8, on day 10. Not bad for a rookie, right? We started exams today, and since my first class doesn't write until Friday, I'm trying to be productive and mark their major lab reports before I have to start marking their exam papers.  It's going slowly... #BellLetsTalk day is in full swing, making my phone buzz and my computer bong with alerts as people tweet and re-tweet. Yes, I am easily distracted when faced with a task I don't always enjoy.  I also wrote a reference letter for a former student who is applying to the SickKids Summer Research Program , and its deadline is before my mark-entry deadline, so I justified writing it before grading papers, too. Just imagine if ...

Do you listen, or just read?

When we were on strike two years ago, several of my colleagues listened as they walked - podcasts, audiobooks - but when I tried it, I couldn't focus on the storyline, so I chose to just walk and talk instead. Fast-forward to this year, and the latest version of the "26 books with Bringing up Burns" reading challenge... one of this year's prompts was "a book you listen to". So I tried it again.  I couldn't get a paper copy for last month's book club choice, so I borrowed the audiobook from the library, and tried listening again.  I found it went well if I was listening while doing another task, like washing the dishes or folding laundry, and I was able to do lesson planning but not marking with a story running through my headphones.  It was slow going until I found I could make it go faster - 1.25 speed sounds a little more robotic, but it sure cuts on listening time.  I actually finished listening to that book as I drove to the book club meeting -...
