All4crystal is right. Use huge logs, ditches and such that she has to learn that she has options other than plowing through. From her standpoint, she's learning that the stuff you put up is easy to go thru so why bother and you don't really want her thinking that. So, get creative, but make it bigger and heavier. If she plows thru, she's just saying that you didn't make it hard enough. Go higher too. Pretty much any horse can jump 2'6" - 3' without any trouble other than learning to pick their feet up nicely. And byw - at least 10 times in each direction so she has time to learn how to do it nicely. I don't mean without stopping, because I like a horse to learn to stand nicely on the other side. But, give it 10 times before you switch directions if you can.
