Fear not! The district has change the profiles so that teachers have more rights to add and delete the icons on the dock that are most useful to them. It is very simple to add these back to the dock.
In this new window, click on the left on Applications.
Find the app icon that you want to have on your dock, click and drag it to the dock and let go!
It is that simple! Have fun customizing your dock to meet your needs!
