Image about Cone of Learning is missing in the paragraph about Active Learning (~line 360)
Links to the other chapters of the Handbook are still links to google docs not to github directories

I hope this will help.

Thanks @vxdaskalou ! The missing figure seems to be currently in the images folder (Open-Science-Training-Handbook_EN/Images/image_5.png) but not linked / listed in the actual episode.
