Gina Bennett
In terms of limiting openness for the sole purpose of protecting intellectual property for wealth creation, I (and many other educators) would agree with Gina wholeheartedly. And I believe that many educators share freely (despite the artificial barriers of copyright) But I think her statement (and the question she quotes from Reinking 2001) are only one aspect of the discussion.
I took an open course from David Wiley in 2007 (Introduction to Open Education) The first 4 weeks were a bit of a slog because he assigned several international reports on the open education movement and its history. Check it out if you're curious...the links are all still active as far as I can tell. Anyway, the reports contained some interesting insights into the unexpected impacts of the United Nations goal of providing universal education. They found that educating young children (especially girls) affected the way they were perceived by their local community (and not in a positive way). They found situations in which people accessed free information but then got stuck because we haven't developed a "translation" segment that helps people interpret materials that are given for free. Much of the educational content that was made available was developed to address a context or products, tools and technology, that were foreign to the people who accessed the materials. The content lost value because it didn't address local conditions and realities. In other words, it's not just "access" and "dissemination" we need to think about; adaptation or recreation of information is also important (which I noticed was addressed in the model described by UVic)
Another problem with sharing is that what we share may preempt the local culture from developing what the people in that culture value and need. Yes, they can modify what we share; but we may also stifle the natural creativity and resourcefulness they have. I watched a wonderful video about Cynthia Hunt (Magic Mountain) where she talked about disseminating information in the mountains around Ladakh by training local instructors and working with them to create educational "books" that promote basic health and hygience to mountain villages. Besides being an amazing woman, Cynthia seems to be a wonderful illustration of helping people to develop their own meaning from information that is new to their culture.
Having said that, I speak from what I've read and discussed with people who have visited and worked in other countries, not from direct knowledge as Gina is doing. But I've thought about these issues a lot and that's why I think we have to go beyond just providing access.
