Open journals

I always believed that open journals (i.e., journals where you do not have to pay a subscription to access contents) are the best way to spread scientific knowledge - actually, you are more read than with other journals, even if the magic math of impact factors does not always do justice to that.

I just discovered a site that lists most of them, and here it the section about educational technologies, I hope this can be of help.
