BETTER BETAS: Hello, educators! We're experimenting with the best way to connect teachers and developers. Last week, we wrote about a teacher who wanted to try out products; this week, we offer you a company with a beta looking for teachers willing to give it a whirl. Nearpod Education lets teachers create content and share it wirelessly to students' iPods and do real-time checks on students' understanding. (Here's a mini video demo.) Remember: betas are free but still works in progress!
