In the largest of a series of ongoing student protests, about 700 young people gathered in suburban Denver to rally in opposition to a new set of high school history standards proposed by a conservative-led school board.

The protest at a busy intersection near Littleton marked a continuation of demonstrations that began Friday with a sick out from teachers upset over issues including the plan to focus on material that promotes patriotism and respect for authority.

The Denver Post reports (http://dpo.st/1mSu4MN ) students waved signs and chanted for about two hours Wednesday.

The Jefferson County School Board proposal comes in response to a new national framework for teaching Advanced Placement history.

Supporters say the new standards encourage critical thinking. Critics say the changes put too much emphasis on the nation's problems.
