Discussing education reform at Stanford University last year, Randi Weingarten, president of the American Federation of Teachers, asked of the audience: “You’re all technology people. 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 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 when it launches in August. “We’ve been trying to find a way to have teachers be able to access information quickly, actively, and share with each other,” Weingarten said. “It felt to me almost too good to be true, that some private entity had created a platform for teachers to be able to share.” Share My Lesson is expected to be the largest online resource for teachers in the U.S., and it comes at a time when cuts to education budgets have led many districts to slash professional development. AFT and TSL have pledged $10 million to develop and maintain the site.
