When I was studying biology, a student asked the physiology professor about Daltons, the unit used to measure the size of large molecules such as proteins. The professor was so used to using the term, he had to look up the definition so he could explain it to the 250 or so students in the class.

Educators refer to “evidence” and “continuous improvement” so often that they appear to be suffering from the same lack of understanding my professor… “What exactly do we mean by these terms?”
