SILVER SPRING, Md. -- Plenty of people dream of leaving their jobs to become teachers. Today, more people are actually doing it.
Peter Vos ran an Internet start-up. Now he teaches computer science to middle school kids in Maryland.
Jaime McLaughlin used to do people's taxes. Now he teaches math to sixth graders in Chicago.
Alisa Salvans was a makeup artist at Saks department store. Now she teaches high school chemistry in suburban Dallas.
These teachers, with real-life experience and often with deep knowledge of their subjects, are answering a call to service that is part of a strategy to dramatically boost the size and quality of the teaching workforce.
