One thought I had, as I look forward to getting a PhD, is that theories come from practice which means that theories about online learning come from individuals creating courses, teaching courses, and collecting feedback from courses over and over and then after all of that work is finished, turning right around and working at analyzing the data, and attempting to answer research questions. In order to have credible research, the questions must be relevant, the measures must be valid and thorough, and the analyses of results must be comprehensive.
