Two Hawai'i public school teachers were among more than 100 science, math and engineering teachers and mentors honored yesterday by President Obama with Presidential Awards for Excellence.

Liane Tanigawa, who teaches science at Pearlridge Elementary, and Seanyelle Yagi, math coordinator at Ka'ewai Elementary, will receive their awards at a White House ceremony in the fall.

The Presidential Award for Excellence in Mathematics and Science Teaching is awarded annually to the best pre-college-level science and math teachers from across the country.

Winners are selected by a panel of distinguished scientists, mathematicians and educators following an initial selection process done at the state level. Each year the award alternates, going either to science and math teachers in grades kindergarten through 6 or to those teaching in grades 7 through 12.

Winners of the Presidential Teaching Award receive $10,000 awards from the National Science Foundation to be used at their discretion. They also receive an expense-paid trip to Washington, D.C., for a White House ceremony and several days of educational and celebratory events, including visits with members of Congress and science agency leaders.

"There is no higher calling than furthering the educational advancement of our nation's young people and encouraging and inspiring our next generation of leaders," Obama said in a statement.

"These awards represent a heartfelt salute of appreciation to a remarkable group of individuals who have devoted their lives and careers to helping others, and in doing so have helped us all."
