Hi Rick: Our experiences with the LMS are really similar - except for the resolution.
I started at a large US community college in 2006, which was using WebCT. Then, as you pointed out, BB bought WebCT and moved us to their own BB version of WebCT (they called it "Blackboard CT") which was unstable. Everyone hated it and there was a clamor to adopt a new LMS in 2009.
My college looked at BB, Moodle (provided by one of the Moodle partners at the time), and D2L. D2L won out and my college has been using it since 2010.
The problem I have now is that I'm *really* tired of D2L. As you point out, it's really tough to get any features added, and the interface really hasn't evolved at all. But the guy who administers D2L at my college loves it and doesn't want to change. I met with him recently and he said something about putting his foot down with D2L "and this time they're going to listen!" I thought, Good luck with that.
Do you, or do any of our loyal readers, have any suggestions about what to do when an administrator is deeply entrenched in an LMS and doesn't want to change? The contract with the vendor is up for renewal in a few years, and I would just like to be able to shop around a little, but I fear I won't be able to - administrators will be unwilling to ask the question, Would we be better off with another LMS. Thanks.
