In addition to praising her for appropriate pottying, give a her a yummy treat, too.  And make sure your praise is done in an excited, little girl voice.  Not just "good dog", but "You are the best dog in the whole world!  I can't believe how smart you are!  What a good puppy!".   
If you are able to collect any pee or poo from accidents in the house, take it outside and put it in the garden where you want your pup to potty.  Dogs often stimulate themselves to "go", by smelling old excrement.   
I'm betting she'll be completely housebroken soon.  She seems to have the general idea.   
Good luck!
