Pear Deck Experiment - Final Thoughts

As I wrap up the semester, it's time for that reflection to see what went right and what went wrong.  This year, I decided to try a Pear Deck experiment.  I felt it would have the audience interact with me and also make use of the technology that my students seemed to have.

It was silly, but I first tried it out in my first ever presentation in front of teachers at the YRDSB QUEST conference.  Looking back at it now, I was quite a beginner and it wasn't the greatest place to try and fail at it as you can see the audience was made up of many big-wigs in the board and around the world.  Oh well, you live and you learn.

I learnt my lesson, and practiced Pear Deck more in the classroom where the audience was a little more forgiving.  It also modeled for my students the importance of trying something new.  Not being afraid to fail.  After a few lessons, I got the basics down.  As with anything new, a teacher has to let them play with the technology first before getting to the real learning that can come with the technology:



The students nowadays seem to be interested in the illuminati, it seems.

After a few trials with my students, I had the confidence to try it again during my 3rd presentation of the year at OAME (Ontario Association for Mathematics Education).

Given the feedback I got from this workshop session I ran, it looks like my Pear Deck experiment was a success 8 months later.  There will be more on my OAME session later in a different post.

Moving forward, to make use of this technology properly, I have to get my pedagogy up to par.  Asking great questions is an extremely important skill as a teacher.  This technology can amplify the effect of a good question or bad question.  I saw that when I made deep, interesting questions, the Pear deck amalgamated all of the students' answers and we could have a discussion based off it.   It allowed my introverted students to participate without having to speak aloud in class.   However, if I made too simple of a question, the students would either not bother to answer or start to graffiti the slide.

When I ask a question, I have to be able to identify if we want to discuss it verbally or if it's a deeper question, I can let Pear Deck do its thing.

When trying to guide, discuss, push, prod - it's important to step away from the projector and to discuss with the class.

When it's time to let the students think - Pear Deck gives the students the space and time to think and illustrate their answer.

I'd like to practice using it next year, but I think I'd have to ask the administration for it, as it is super expensive.  Perhaps I'll try a similar software in Nearpod, next year.  

In the end, however, I had fun trying something new and the experience has made me a better teacher - which is all I can ask for.

Earth and Space Wrapping Up

To wrap up the semester, I decided to set up a bunch of guest speakers.

First up is a writer for space.com on the latest in astronomy apps, and astronomer -  Mr. Chris Vaughan (@astrogeoguy)  He arrived at the school at 8:15pm and 12+ students came trickling in afterwards.  It was a tough time for the majority of my class as there were many tests and assignments due that particular week.  A definite reason to not run this workshop towards the end of the semester.  Next time I'll change the time of year this occurs.    


Nevertheless, we saw the moon in spectacular detail, then Jupiter, Mars, Saturn, and then a whole host of stars came out.  Antares, the "equal to-Mars" star, which twinkled, giving away its star status making it distinguishable from Mars.  We saw Vega, the brightest star in the summer sky.  Other salient and very interesting things in the sky was the ISS and the iridium flash by a satellite.

Second up was Ms. Julie Lum, parent council chair for the past 3 years as well as a geologist + engineer for the Suncor/Shell.  We managed to tag-team this presentation, as I helped convert her quiz into a kahoot.it.  The change from last year's presentation to this year's was impressive as she incorporated videos and presented Shell's vision of clean energy and latest in fracking in an engaging presentation.  It's pretty cool to see a parent council chair who is willing to try teaching.  As a parent of 3, parent council chair, and now a 'teacher', she has put on hats as a parent, administrator, and teacher.

he skillfully guided students through their misconceptions of the universe.  He would take students' inputs and ideas and weigh them by guiding them through logic  - pulling on some of their ideas, like a loose thread, until it came loose.  He followed them through on their misconceptions to point out its weakness from their own logic that he helped guide to eventually crumble their misconceptions.

He arrived early, and I gave him the option of speaking to grade 9s.  He held a Q&A session.  He taught with humility and incredible openness.  The questions that those grade 9s asked (most of which came from my ex-grade 9 math students who I have encouraged to ask questions) were great - how is the universe expanding, how big is the universe, why is it so much harder to breathe as you get higher, how do we measure how big things are, etc.  Again - he has never taught grade 9s, but his ability to take such difficult concepts and simplify it for them was like watching Michaelangelo paint the Sistine Chapel.  He used anecdotes, simple math analogies, and drew upon everyday experiences to satisfy their questions.

He apparently teaches astronomy to humanities students - UT forces humanities students to take a science.  I could see that he used the same tone with my high school students - where every word he used was measured and carefully selected so as to keep his audience engaged no matter how difficult the concept.  I could tell that he used this tone and linguistic style for both the grade 9s and grade 12s as there was one hint where this 'armor' broke - one of my grade 12 students asked how can the universe be simultaneously infinite in size and infinite in mass.  His tone and pacing changed ever so slightly as the question started to enter the realm of math.  He excitedly rattled off the density equation and explained how the beginning of the universe can be infinite (because the universe is anything and everything that will be), but also be small in volume, exploding the density to infinity.

A colleague pointed out that I can do this same process as the professor with my math students - where I can help guide a student to use their own logic to to help them see the error of their own math solution.  And it's true...I can do that because I know the subject matter.  I just don't know my astronomy well enough to get to that level.  So it was spectacular to watch and see this occur for an astronomy course.

His visit, among many things, showed me that I have a long way to go as a teacher.  It was really fun to watch the art of teaching.  Time to get to work!
