Accredible has done a lot of work to try and address the concerns that hiring managers have with online learning. The top 3 concerns we have identified are:
1. How do I know if you really did the course? 2. How do I know how seriously you took the course? Did you just browse through it passively or did you really do every assignment and maximize your learning? 3. How do I know if the course was high quality or of sufficient depth?
I believe the best way to address these concerns is to change the structure of the credential itself to have evidence of learning embedded into it. We (Accredible) have been working with some MOOC providers to create a portfolio credential tailored for this kind of situation - currently in trials and going well!
So, hopefully, once the credential formats update to match the learning environment, this will become much less of an issue.
