Flipped Classroom – Teaching the World
Up until this point, I have been creating my videos, and posting them to (i) the “Coppell IB Math” Google Site, and (ii) the iTunes U courses I created for Math Higher Level 2, Math Standard Level 2, and Math Studies. I’ve also been posting the videos on YouTube, just to give my students different options for locating the videos. And I was happy as long as my students were able to access the videos.
Little did I know that, over time, it wasn’t just my students that were subscribing to my iTunes U courses. While I have only taught about 300 Higher Level 2 and Standard Level 2 students, I have noticed that over 1700 people have subscribed to my HL2/SL2 iTunes U course! Similarly, I have taught a total of 10 Math Studies students, but more than 800 students have subscribed to my Math Studies iTunes U course!
Then I started looking at my YouTube videos. By the way, YouTube allows you to see who has been watching your videos, and can give you these statistics in as many ways as you can imagine. Not knowing this until recently, I decided to investigate. First of all I have 198 subscribers, but I only recognize 17 of them as students I have taught in my class. Then I went to see how many views … over 40,000 views!! This raised some questions, like: Which video do they watch the most? Where are the viewers from?
Apparently, my 5 most watched videos, as of August 30, 2015, are:
- 10,515 views – Derivatives of arcsin(x), arccos(x), arctan(x)
- 8,539 views – Fermat’s Little Theorem
- 5,064 views – Linear Congruences
- 1,906 views – The Chinese Remainder Theorem
- 849 views – Linear Diophantine Equations
And the viewers come from countries all over the world. Here are the top 10:
- 16,206 views – United States
- 3,462 views – India
- 2,926 views – United Kingdom
- 2,846 views – Canada
- 1,452 views – Philippines
- 876 views – Australia
- 778 views – Sweden
- 680 views – South Africa
- 509 views – Malaysia
- 481 views – Norway

I never dreamed that when I would start the Flipped Classroom that my silly little videos would help teach students across the world. And the YouTube watchers (again, not my students) are also very generous with their compliments too!
- “Thank you! I am teaching myself number theory with the goal of making it part of a high school discrete math course that I’d like to teach. This is most helpful and explained quite well. I will definitely check out your other material.” – J.M.
- “I will have a paper 3 IB exam tomorrow, thank you so much for your videos! They are all really helpful! :)” – T.V.
- “Thank you Ian! Finally i got this!” – L.L.
- “wow.. you are saving my life..your explanation is so clear and easy to follow..thank you very much..” – K.K.
- “Hey Ian, I really appreciate this video. You do a great job with these videos. In 10 minutes you clarified something I’ve been wrestling for a week since my “professor” explained it in class. Molte Grazie!” – A.G.
One YouTube viewer from Lapu-Lapu City in the Philippines liked my video on Fermat’s Little Theorem and asked if I would explain Wilson’s Theorem. I told her that it wasn’t part of my curriculum, but afterward, I became curious as to what Wilson’s Theorem was. So I researched it, found a proof that I could follow, and made a video for her.
