I have fellow teachers ask me if if I forgot to teach a subject area because my former students did not seem to know anything about the topic.
I might reply something like, "The topic we spent three days on?"
Is it because they just learned the information long enought to take a test but never learned it in the first place? Probably. I have students that do not care about the subject at hand and they will not remember the information if they do not care about it.
