Eddie Woo is Head Teacher Mathematics at a public comprehensive high school in Sydney, Australia. Recently he has become a YouTube hit! How did it all begin? Unfortunately, Mr Woo had the experience of teaching a student a few years ago who was very ill and in and out of hospital regularly. He noticed that what the student craved, was to just feel normal, to do normal things, not have appointment after appointment or treatment after treatment. By recording his lessons, the student was able to keep up with class.
Since then, Mr Woo has continued to record lessons and his channel has expanded. I highly recommend any secondary math teachers to visit WooTube.
