Less than two years after being named Alabama's Teacher of the Year, Ann Marie Corgill resigned her post this week, citing her frustration with bureaucracy. After Corgill was moved from teaching second grade to fifth, she was told she wasn't qualified to teach fifth-graders.

In January, Corgill was named one of four finalists for the National Teacher of the Year award. She is a 21-year teaching veteran whose story — and candid resignation letter — has made waves in the education community and beyond.

Like many first-year teachers, Luisana Regidor has a lot on her mind. There are lesson plans to write and papers to grade as well as a dozen other things: evaluations, observations, fundraisers, class trips. It's overwhelming.

"Last Wednesday, I left here and I got in my car and I just cried," says Regidor, who teaches U.S. history at Schurz High School in Chicago. "Everything was hitting me at once."

Regidor, 31, says other teachers warned her that the first year could be rough, but in September she was full of ideas and energy.

Seattle Public Schools teachers have voted to strike beginning the first day of school, Sept. 9, if there's no new contract.

Teachers call the district's proposals "disrespectful."

Ah, back-to-school season in America: That means it's time for the annoyingly aggressive marketing of clothes, and for the annual warnings of a national teacher shortage.

But this year the cyclical problem is more real and less of a media creation. There are serious shortages of teachers in California, Oklahoma, Kentucky and places in between.

A stack of research suggests that all the classroom technology in the world can't compare to the power of a great teacher. And, since we haven't yet figured out how to clone our best teachers, a few schools around the country are trying something like it: Stretching them across multiple classrooms.

This fall the NPR Ed team is celebrating great teachers and examining what makes great teaching.

Ayodeji Ogunniyi was a pre-med student when his father was murdered by three young men. So Ogunniyi decided that becoming a teacher, not a doctor, would help ensure his father's death was not in vain. (This StoryCorps interview initially aired Oct. 30, 2011 on Weekend Edition Sunday.)
