Children do a lot of their learning by watching others. If you aren't eating in front of her, how is she supposed to learn how to eat? She can't be expected to hold a spoon and use it to feed herself if she doesn't watch anyone do it. Have you ever eaten with chopsticks? If so, did you just pick them up and were a pro? Because if you are like the majority of Americans, someone had to SHOW yo how to use them.
If she is chewing on the spoon, I say, let her. Over time she will develop the dexterity to manipulate the food onto the spoon and into her mouth. She might just be frustrated and needs patience. Give her finger and spoonable foods so she isn't frustrated.
