Hundreds of thousands of students and teachers took part in protests Thursday as part of the National Day of Action to Defend Public Education. Much of the day’s focus was on the university and state college campuses of California, where students face a 32 percent tuition hike. Thousands of California students staged a one-day strike and took part in rallies from San Diego to Sacramento to Humboldt County. Actions were held in at least thirty other states, including here in New York, where protesters rallied outside the offices of Governor David Paterson. It was the largest day of coordinated student protest in years.
