Online-only classes are problematic at best due to the nature of the interaction. I thought most of the instructors did an excellent job with the materials they had to hand. One difficulty they had was that many of the students were not academically ready for graduate level work and had trouble comprehending texts and writing comprehensible papers. I was deeply grateful that grading their work was not MY cross to bear. The ongoing discussion boards and required submissions did ensure that assignments were completed, however poorly and semi-literately in some cases.
I've taken excellent online classes at the University of Arizona that were really engaging and stimulating; I expected better from a 100% online school like Jones International University. I was thankful they didn't require "group projects" from students scattered all over the country. I would have hoped that an online school would offer useful, "hands-on" courses in designing online classes, but again, I was disappointed.
I know that JIU's completion rate is not very good, but I would not blame the school itself (instructors and classes) for this failing. The truth is that many of my fellow students were simply incapable of completing graduate-level work without extensive remediation. They may have earned their Bachelor's degree twenty years or more earlier and their brains were focused on teaching math to third graders more than text analysis and educational research. For some of them English was not their first language, which hampered their reading and writing. I think the school could better serve its students by offering a "college refresher" for grad students who have been out of school for many years.
