Diane Callahan is known as the teacher who never slows down. Through she's restricted to a scooter because of multiple sclerosis, Ms. Callahan is one teacher who always looks on the bright side, believing that teachers should demonstrate for students how to remain "strong and determined" when facing adversity. "We all have difficulties in life we have to face," she says, "but it is so much easier when we have a positive outlook." Using a lab-based inquiry method with real-life science problems to solve, Ms. Callahan thrills her students with the excitement of discovery. In the process, the children stretch themselves intellectually. She sets high expectations for her students and herself, because she wants to "change the world" through her teaching. And she makes kids "work harder than they ever thought they could" because she believes they must become passionate about their lives in order to turn dreams into realities.
