In all these discussions about open knowledge, open access, global education, et.al., my deepest concern goes out to the poorer countries of the world. It is not only how it can help them meaningfully but could they really have the means and attitude, the right frame of mind -- the psycho-emotional and socio-cultural profile or potential -- to
be helped by these. Here are some experiences from the third world.: The biggest threats to universal education in the third world -http://www.developmentgoals.com/threats/universal-education.html; Open And Distance Learning In Professional Development In Third World Countries -- http://www.ou.nl/Docs/Campagnes/ICDE2009/Papers/Final_paper_296Cosmas.pdf

Here's a prompter on the challenges facing open access education. I think the challenges are not the same for all countries. it depends on the economic status of the country and cultural receptiveness. No one formula can be applied to all. So, can a true global education be achieved for all?

Here's a selection of resources on Global Education, Citizenship, Values, Racism, Human Rights, Citizenship, Beliefs, Intercultural Understanding, Multicultural Perspectives and Studies of Asia.
