Thanks, Juan, interesting. En.wv largely represents a view that education is about people and what people do, not just about content. Education as pure content is academically discredited in the world of education, there has come to be much more concern about process, learning as process, a process that continues, life-long, if people learn how to learn, which includes exploration and investigation, not merely imbibing what has been predigested by someone else.
On En.wv, the forces toward reduction of education to content, which, then, of course, must be "correct" and "approved," are active, but do not dominate.
Wikiversity, at least en with which I'm familiar, is the only WMF wiki where discussion of topics is actually encouraged. You can be blocked on Wikipedia for trying to discuss an article topic on the Talk page there, and sometimes even for trying to discuss in user space.
One of the oddities I've seen is that, on Talk:Cold fusion it is actually recommended that if you want to discuss the topic, you use a mailing list that focuses on fringe and weird science, the vortex list, but attempts to link to the Wikiversity resource, where discussion can actually help develop learning resources, have been interdicted, on the argument that Wikiversity is "self-published."
Definnitely, there is work to do letting Wikipedians know about Wikiversity. It would be ideal to suggest to Wikipedians that if they want to talk about and learn about the topic intereactively, that Wikiversity is open for this, instead of what usually happens: they are told to go away.
In real universities, around the world, and for centuries, what might be called "fringe" views are studied, developed, researched, and taught, as such. Individual professors express their opinions and do original research, and students do the same, in course work and for degree dissertations and papers.
I can easily see a grading system as being possible, and overall neutrality policy suggests that poor work should not be prominent, but it takes a lot of work to design and implement some overall system. En.wikiversity is still in very primitive condition.
