Discussing education reform at Stanford University last year, the leader of one of the nation's largest teacher unions decided to turn the tables and ask a question of the audience.
"You're all technology people," said Randi Weingarten, president of the American Federation of Teachers. "Could you actually help us?"
Weingarten said she received one call — from Louise Rogers, chief executive of TSL Education, a United Kingdom-based company that operates an online network that lets teachers around the globe access, review and discuss lesson plans and other learning materials.
The result of that call, to be unveiled Tuesday, is Share My Lesson, an online portal that teachers will be able to access free of charge. It is expected to contain more than 100,000 user-generated materials.
