NEW ORLEANS (AP) — Education Secretary Arne Duncan will visit New Orleans on Friday to get a first-hand look at reforms the Obama administration is pushing nationally, reforms that remain a work in progress locally. The reforms including tying teacher pay to student performance and extending the school day are part of an overhaul that began after Hurricane Katrina, with hopes of turning a public school system known for poor academic performance, administrative corruption and neglected buildings into a model for innovation.
