The Holy Trinity of Checking for Understanding

I'm a big fan now I call this the holy trinity of checking for understanding. Oli, do you think it's important to vary the types of questions we ask when we check for understanding? It tends to be more of a kind of procedural question and I just fear same with the retrieval that unless we're testing the depth of understanding by varying these questions around a bit maybe we're only getting a sense of that kind of surface level so where do you stand on kind of different types of questions you asked to check for understandingYeah it's a good question and again not something I've thought about heaps but I think maybe that's just because it'sdifferent concepts and different understandings
