I am Head of Mathematics at a leading international school in Thailand. I am also a current IB examiner for the IB Mathematics coursework with an MSc. in Mathematics. Some of my websites include: ibmathsresources.com and intermathematics.com. These are used by millions of students for IA ideas and support IB teachers across hundreds of schools worldwide. I have led webinars for IB teachers on the coursework process and have written hundreds of blog posts and articles exploring interesting coursework ideas. I thought it was time to make a course to share this with the IB community - I hope it is useful!
