Helping children learn through video tutorials, songs and fun activities! Hi I'm Vern, and my students call me Madam Koo - Mdm Koo in short. I'm very passionate about sharing information with others, and helping children learn. I post educational videos on physics, math and science, relevant for students in Singapore. Previously I also share information about places that serve vegetarian food in Singapore and share activities that engage my children. You can see them in my older videos.
