President George W. Bush welcomes Jason Kamras, the 2005 National Teacher of the Year, to the Oval Office during ceremonies Wednesday, April 20, 2005, at the White House. Mr. Kamras, a 1996 Princeton graduate, teaches seventh and eighth grade math at John Philip Sousa Middle School in Washington, D.C. "Teaching is a commitment to equity and opportunity for all children," says Mr. Kamras, who took time away from teaching in 1999-2000 to earn his Master's degree at Harvard. "It is a promise of a better future for those who have been left behind." (UPI Photo/ Eric Draper/White House.
