Hi Philip,
I've just visited your "learning analytics block website page" and am surprised at your choice of "Traffic light risk view" colors. They are in the exact reverse position to what I am expecting. Surely a moodle user with a high engagement score should be shown with a green light and one with a low engagement score with a red light. Or maybe we are seeing things differently in the Northern hemisphere where I live and the Southern hemisphere where you are.
All the best,
Joseph
