Tools/Understoodit/teaching approach

From OER in Education

Poll(tool) tools can be used for quick assessment(ta) or questioning(ta) in and outside of the classroom. They can also be used to allow pupils to give feedback. Understoodit.com is a particular sort of tool which - whether on a PC or mobile - allows students to use an app or webpage to state whether they are confused or not; it can thus be used for 'traffic lighting' understanding.
