How old is she? The techniques to help children learn are very different from a kindergartener to a high schooler.
If she is a young child, your question may be to vague. If you say, "Tell me about ________." you should have visual cues about what she learned, so it will help cue her like a picture of a horse if you learned about horses, etc.....
I am sure you have done your homework and know that there are many different types of learners. She may not be an auditory learner and asking her to parrot off what you taught yesterday may be a huge stretch for her.
Work hard on making sure she knows that you are NOT frustrated. You have shared that she is afraid of being wrong. It will be important that the environment you create for her is one where she feels safe to take risks and be wrong. This is an important part of learning.
Even though I have thought of homeschooling my children, your situation is precisely why I am afraid of formally teaching my own children. And I am an educator with eleven years of teaching all types of children.
Good luck! Remember all people (children and adults) learn best when their affective filters are low. In other words, if you are not stressed about what you are learning and the information is age appropriate, learning will happen. Be patient!
