To answer this question I took a look at Jennifer Maddrel’s four week post. Her matrix is very clearly and summarizes the most important characteristics of the open education projects mentioned.
What do these representative open education projects have in common?
What they have in common is their purpose, share free educational material.
What differentiates them?
Their focus area, their licensing, their contributors etc. I think that they only share their purpose.
In the context of open education projects, what does "quality" mean?
To my mind quality can be measured in the terms of how a material can help a learner to learn. I mean, a educational material can be very beautiful with a lot of colours and pictures but may be it is not useful to a learner. However a simple plain text may help a learner to learn more than those materials.
As I Jennifer’s post seems very interesting to me I want to comment some of what she says.
“I question why (in this day of Google and other search engines) efforts aren't moving away from repositories - or specific OER directories for that matter? Wouldn't our efforts be better spent on properly categorizing and tagging the original content so that it can be "found" by the increasingly sophisticated search engines? Why should learners and teachers be forced to travel from one site to another to find content? Shouldn't they be able to pull in the content that is properly identified and tagged?”
What would happen if you have a material in a repository and a reference pointing to it in a directory and the author of the material modifies its content? What would happen if the repository’s URL changes? In both cases you will have your metadata out of date. For doing it well you will need to check your metadata periodically.
And apart of this problem you have to take into account that search engines like Google only index the content of the resources no its metadata if you would want to search materials attending to its subject you will surely find nothing.
A few of spam here:
In the University of Alicante we are working on a new e-learning platform called LOR@. It is also an Open Education Project, you can try our content manager, Rockl2, here. Note that it is a beta version and all suggestions are welcome. (For entering to Rockl2 you have to register yourself , push the Register button).
