Recently, I had a really bad field experience placement. My supervising professor was very abusive and my master teacher was a close friend of hers. Though it was a valuable experience and I learned quite a bit, I had to leave the placement suddenly due medical problems brought on by stress. The professor forced me to withdraw from the course or said she said I would fail. I tried to work with her, but she refused. It is a very long story, but I will probably transfer to another credential program this fall. Should I mention my field experience on my resume? I did learn a lot from it. Of course, I won't give my master teacher as a recommendation and I wasn't "fired," but it still didn't end well. Thoughts?
