English instruction a result of changing global education systems?

For another class, I have been doing a lot of research on the effects of globalization on education. An interesting thing I have found that I think ties in very well to the idea of language planning and language policy is that as countries interact more and more on a global rather than a local level, many countries (especially developing ones) choose to simply throw out their existing education systems and adopt the systems of more powerful countries. This includes teaching the language of the education system adopted, and I could see how this would certainly "wreak havoc" on the education system, to borrow a quote.

For example, Islamic education is traditionally focused on "holistic" education that combines religion and science. But a recent phenomenon is for the elite Muslims in the middle East and other Islamic areas to send their children to private schools that feature "western" educations and are taught in English. Though there are many critiques, including from the governments of some of these countries, for not having as "holistic" as an education, they are growing in popularity.

Just thought it might be interesting to think about language spread under the framework of educational changes, which can be part of government language planning and policy, but isn't necessarily.
