Wanted: More Math and Science Teachers

He arrived at The Engineering School, a high school in Boston, with a bachelor's degree in biology and a master's degree in teaching from Cornell University. But classroom management in his biotechnology classes has been the biggest learning curve, as it usually is at the start.

To illustrate natural selection, he gave students "critters" with forks for mouths, and had them try to pick up uncooked rice. Then he gave some of them spoons, to show that the critters who could get more rice would live and pass that trait on to future generations. "My first-period class got a little out of control and there ended up being rice everywhere," he says.

Now he's reflecting on how to improve the labs to keep students focused. He can tap peers and mentors for ideas.

The KSTF fellowships can be renewed for up to five years and $150,000. Out of 128 awarded since 2002, fewer than 20 individuals have left teaching, Collins says. By comparison, about a third of new science and math teachers typically leave the profession within three years.
