An Asian-Australian math teacher’s unique teaching style has turned him into Australia’s favorite high school teacher.

Co-head mathematics teacher Eddie Woo, whose parents migrated to Australia in the early 1970s, has been teaching at Cherrybrook Technology High School in Sydney for about ten years now.

His charisma and technique have earned him the admiration not only of his students but other learners across the country after he began recording all his lessons and then uploading them online for other learners to view for free.

According to ABC.net, Woo began uploading videos on YouTube to help a student who was diagnosed with cancer and missing school back in 2012. Soon, his videos became a hit on the video-sharing site, reaching new learners and fans beyond the country

“Wootube” now has over 50,000 subscribers, accumulating almost 4 million views in total.

“I did some rough back-of-the-envelope calculations, as a maths teacher would, and if you add it up, that’s about 11 million minutes of people sitting there watching me run around in front of my whiteboard explaining concepts to my classes, which is just mind-boggling!” Woo was quoted as saying.

His efforts have not gone unnoticed. According to Cherrybrook Technology High School principal Gary Johnson, Woo’s channel aids in partly making up for Australia’s shortage of maths teachers. His unique style has also drawn interests from those who are not generally into math.

To keep lessons interesting, Woo often uses pop-culture references in demonstrating mathematical equations. He engages students by making them laugh and keeping them entertained while learning.

Year 12 student Emily Shakespear explained to ABC.net how Woo’s teaching style has made her more interested in the subject.

“I don’t want to say it, but he sucked me into maths,” she said.

“It’s difficult to understand how someone in Sydney can influence thousands of people across the whole country,” said Owen Potter, another student in the school.

Passion personified, Woo is the teacher one would wish he/she had as a student. Thankfully, he has made it possible so that anyone can be his student.
