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!

Kahoot is a Hoot!

One day, one of the students didn't have their presentation ready.  My emergency backup lesson plan was to run a kahoot on random space questions.

Kahoot.it is the latest in clicker software, where students can use any technology whether it is a phone, laptop, ipad, etc.  It's a good thing I was in the 21st century classroom as any student without a mobile device went over and grabbed a laptop or ipad.  

Kahoot measures who gets the answer quickest and awards the fastest student...or teacher in my case.

However, I didn't always win - the youth that my students have over me was shown in the next game. Their reflexes were much faster. See exhibit B below:

Anyways, I had quite a bit of fun and was fully engaged.  Some students took notice and included a kahoot into their next presentation.  (I lost that one too...but my excuse was that I didn't fully pay attention to content as I was scribbling notes on their presentation as a whole to help provide them with feedback on their next presentation).

Inquiring the Surface Area of a Sphere Through the Peeling of Oranges!

It's getting closer to the winter break, so it was great to have some hands-on activities to add some spice to the classroom for my academics.

It seems like my applied class is getting all the engaging and interesting approaches to math, so this was quite refreshing for myself (and especially these academic kids) to have this tangerine activity to explore the surface area of a sphere.

First thing we did was take a good look at the tangerines and noted its differences from a perfect sphere.  We then went on to talk about how perfect mathematical spheres don't exist in the real world since once one gets into the atomic level, things just aren't continuous.  This sort of statement really bothered some of my students  that one went home and told their parents.

Nevertheless, upon noting the clementines' (lack of) sphere-like properties, we proceeded to take a guess as to its surface area in terms of its radius, and thus area of its 2D ('projection'?)  version.   Each partner made their guess:

Looks like they their estimation skills are almost en par with my applied students' skills which has been honed through the Dan Meyer's 3-act process.  That...or they looked at the formula sheet or remembered the answer from their elementary school days.

Let's see how they did:

 I guess they couldn't be bothered to peel that other portion there to get its true surface area?  I guess I should have done more teaching and less snapping of pictures here, as I could have demonstrated that by peeling the skin into smaller pieces would more accurately depict the surface area.  Right now, much of the 'surface' area is used for the third dimension of height severely downplaying the true surface area of this orange. 

 That clementine there looks quite tasty.  I must mark these students' self regulation skills to be excellent in their ability to stay on task without eating some juicy fruit.

 Now that clementine looks quite symmetrical...and tasty.

Ahh, "four" circles!  The 'true' answer.

Now this group featured a student who made the best notes ever and another student drew some of the best art on evaluations.  The illustrations left behind were both profound and thoughtful.  It's no small wonder that they took the time to rip the orange peels into symmetrical sizes to create the above work of art.

Anyways, this activity proved to be quite memorable.  It's a good one and one that I'll continue to do every time I teach grade 9 as it somewhat demonstrates how the surface area of a sphere is 4πr^2 or the equivalent of the area of four circles.   

Hooking Students into Solving Equations

As I approached this topic - it scared me.  Typically, my 9 applied students don't take this concept of solving equations very well.

However, it went extremely well.  Better than I thought.

All my work emulating Dan Meyer has paid off, as they gobbled up this math lesson with such focus and creativity that amazed even me.

The community of openness, willingness to make mistakes, and the growth mindset was on full display.

I started off with the typical Pearson textbook problem on a Powerpoint, and had them figure out in any method how many spheres are in the bag, assuming that this was a balance.  It's my attempt at having them recall some prior knowledge:  

 Then, I had them try out this question:

I asked them - "What is the difference between this question, and the previous question?"

Student: "It's more complicated."

Mr. Shin:  "Yes it is more complicated.  There are many ways that this question is more complicated.  Can someone elaborate on why the second question is much more complicated?"

Students:  "Uhh...more spheres, more items, and more bags on both sides."

I then went on to explain that there's a method to "simplify" (bad term to use, I'll admit.  I have to ask my colleagues for the proper term.  They're much smarter than I on the formal aspects of mathematics) complicated equations like the second picture  to become simpler equations like the first picture above.

A little bit of a hook was made to some students, but as usual - not all.  Well, at least I got some without having to use any symbols or use of any math.

At this point, though, I had to introduce the use of symbols to solving simple equations on solving equations.  I made sure though, that they as a class were able to predict  each math line that would pop up on the Powerpoint before I flashed each line on the screen.

Continuing on to use think pair share and whiteboards for the next two questions makes sure that at least half of my 22 students are able to get some portions of this concept.

On day two, we built equations.  They made up their own equations using cups and cubes.   I also encouraged them  to draw out questions for their partners.

Talk about students being leaders in their learning - giving them the responsibility to create their own questions.  Fractions and decimals came out as partners answers others' questions - it was very interesting that they would take it back and try to 'fix' it as if there are problems with fractions.

However, going through that exercise of integer answers only really made them think creatively.

This is why I like the applied classroom - they take liberties on things like the money bags up top and even this:

Bunny rabbits and money bags are so much more interesting than spheres.  Money bags is better conceptually though, than the rabbits who have eaten candies, but at least they're taking their artistic liberties.

And...they're really into it - a few of them started on their homework from Knowledge Hook right away on Friday night, and there is NO red square so far.  One video was watched for clarification so far...good news good news.

 I guess the real test is:  how many more 9 applieds will they even attempt their homework by Monday? 

 
Stay tuned! 

Grade 8 Parents' Night

Hundreds of parents and students descended at our school just to see what Pierre Elliott Trudeau has to offer.  They want to compare our school with the other options out there - the Catholic board or private schools.

I found a few helpful students and we spent most of the time just preparing a room for that would show the parents and students the different math pathways.  Presenting the different math pathways available would benefit the parents and students no matter which school they chose.

We decided to set up the classroom in a way that they could 'walk' the different math pathways available and see where each pathway ends.

As a result, our school has run the transfer course for the first time.  The principal spent some efforts advertising this course at the grade 8 parents night 11 months ago.  She advertised the applied and transfer course pathway as an option for any students that scored a level 2 or below in their grade 8 math scores.  

With the applied + transfer course pathway, the students are exposed to 1.5 credits of math rather than just the 1.0 credits in the academic grade 9 pathway.

There's no way to tell if this applied + transfer course of 1.5 credits is enough to prepare them for grade 10 academic.

This scares me more than their EQAO scores.

Which I guess, in many ways, a good thing.  I'm more concerned about their transition than their EQAO scores.

In my younger years, I'd care too much about their EQAO scores .   I've now realized that if I take care of them as students, the EQAO scores will take care of themselves.  EQAO is subset of what and how they should learn.

I'll be sure to track their success next year.

PS:  The best part of the night was watching a few students explain to the parents what the math clubs and math education is all about.  It's interesting to hear of their experiences.
