In the pattern (typeSavoirApprenant "implicite" (get ?connUO objet))
you clearly want the function call (get ?connUO objet) to be evaluated during pattern-matching, but your syntax is incorrect. Jess is trying to interpret your function call as part of the pattern -- i.e., asuming you think that "get" is the name of a slot in the typeSavoirApprenant fact. One syntax that will work for you would be like this: (typeSavoirApprenant "implicite" =(get ?connUO objet)) the "=" sign turns the function call into a "return value constraint" -- i.e, a proper part of the pattern.
