FliP-CoIn is a multiple-choice conceptual assessment instrument for improving fluid dynamics learning and teaching. I give insights into why and how FliP-CoIn was developed and how it is best used for improving conceptual learning. Further, this work presents evidence for several dimensions of FliP-CoIn's validity and reliability.
