I am a university professor who occasionally uses Blackboard. Some thoughts:
I certainly agree that Blackboard is overpriced and somewhat painful to use. I don't use it much. I mainly create my own web pages from scratch, which I find to be about as easy as using BB, and rather more conducive to my aims (which include making most course materials available to the public).
But then there's this:
> It forces, and reinforces, an entirely teacher-centric pedagogical model.
Um ... that assumes that the BB area is the class, which I find rather silly. I use my websites (and BB now & then) to get information to students, including handouts, announcements, solutions, links, and source code. I could do all this on a physical bulletin board, but the paper cost would be excessive, and it would require students to type in source code, instead of simply downloading it.
But my website is not intended to be some collaborative space where students learn together. On the contrary, the model I follow is to provide my students with resources, and allow them to learn as they see fit (together, if they wish; sometimes I require it). After all, high school is over. My students are adults. They run their own lives. And there are plenty of collaborative learning spaces around here. They are called "tables", and they are used a lot.
This is not to say I'm against the online-collaborative idea. Certainly, if someone figures out how to enhance the educational experience with some kind of computerized thingy, then I say more power to them. Let's get lots of start-ups in this area to come up with lots of interesting things. But in the mean time, I don't feel obligated to somehow "manage" my students' total educational experience.
> The very concept of a “learning management system” may itself be wrongheaded.
Oh, certainly. But after all, "learning management system" is just a term invented by marketing people. We don't have to take it to heart.
