For the last couple of weeks I've been following Diane Ravitch's blog - A site to discuss better education for all in the US.
Diane is an American educational researcher, historian of education, and public intellectual who has held public office for both Republican and Democratic administrations. She has a prodigious list of publications to her name, and - born before WW II - she is old enough to have experienced and observed the huge changes in US society - including desegregation - from the mid 1950s onwards. Diane is using her blog to wage an astonishingly energetic personal campaign - averaging 200 posts per month - to protect public education, and to challenge what Pasi Sahlberg memorably calls the GERM (Global Education Reform Movement) ideology that asserts that schools will improve if there is competition, standardization, school choice, and test-based accountability. If an average of ~5000 page downloads per day is anything to go by, Ravitch is hitting a chord with her readers.
What makes Ravitch's work all the more interesting is that she is someone who has changed her views.
