Oak Ridge High School math teacher Phyllis Hillis has received the 2011 Presidential Award for Excellence in Mathematics and Science Teaching.
Hillis, who has taught math at the high school since 1979, was one of 97 U.S. teachers across the country who won the prestigious award.
Winners receive a $10,000 award from the National Science Foundation, and they have been honored in a three-day event in Washington, D.C., this week.
The awards are the nation’s highest honor for math and science teachers.
