If there isn't a time issue you're working with - for instance, is she going to go to a daycare/preschool for which she needs to have her potty-learning down pat? - then I think letting her do it in her own time is still a good idea. My daughter started to learn how to use the potty at 2, then changed her mind and didn't start again until she was 3 1/2 yrs old.
I finally figured out that it was a control issue with my daughter; the more I (or my mother) asked her if she needed to use the potty, the more she refused to use it. I finally instructed EVERYONE in the family not to mention it to her. Even if she was doing the "potty dance", we didn't say a THING. Then, I sat down & explained to her that SHE was the Boss of her own body. She decided when and where she was to Poop & Pee; I told her that it was important for the health of her body that it be allowed to get rid of it's waste at least once a day...and that her skin would be MUCH healthier if it didn't have waste sitting on it several times a day & night, every day & night. She thought about this - said "Okay", and immediately started using The Big Potty. :)
I don't promise this'll happen with your daughter, but it is a good idea to empower them by telling them why you are hoping they will learn this; and I did find that Bribery and Peer Pressure were useless things to try. Bad examples to set, too.
Good luck!
