If you want to try to make it work - try being the first person to say at your next standup "Hey I said I would get this done but I got blocked by this thing. Anyone have reference/documentation they can share so I can get unblocked?"
We're not all perfect so I know there's a part of the project that makes your head scratch or is blocking you. Come up with something to get the ball rolling. In the context of a standup its important everyone feels like they're in a safe environment. Anyways, just model the behavior and see what you get.
I know, I know - now you're the one in a vulnerable state. But that's why you're a leader. You do the things others are afraid to for the betterment of your team and the quality of your product.
I wouldn't bother with trying to change their behavior in the standups at all -- but that's solely because in the places that I've worked that did this, standups were of no actual value. If the team is functioning well, then everyone already knows where everyone else is anyway, and real help is obtained and offered outside of meetings.
