I am going to post how I was able to track this down for anyone that had this problem.
I opened the Front Page and went to View Source. Then I searched for loading-resource.
For me the script appeared between two of my course listings. I went to the course directly above the script and found that the course was infected as well. In the course, I also viewed source and found and deleted all three instances of the script.
I also then changed the password of the offending teacher(!!) and notified her.
I will keep an eye on it but hope this maybe helps someone else.
