My biggest concern with the new structure - minus hating all the general changes - is that I cannot find a clear path to the lessons and quizzes to be able to assign them. I click on "Explore" and I go this general menu/overview of topics that used to be in a side toolbar, but now, it's the main page and its not easily navigated and it shows me nothing other than the titles. Also, when I click on the lesson I want, it doesn't take me to a place to assign this lesson???? I have tried Assign from the gradebook and that is even more convoluted. I used Khan Academy regularly in my classes, but now I'm not using unless I'm desperate and I have time to relearn how to navigate the site - because nothing about this new setup is user-friendly.
