Last Friday I wrote a post about Tom Barrett’s latest installments to his Interesting Ways series. At the time, one of the installments, Interesting Ways to Use Audio in Your Classroom, didn’t have any ideas or resources in it and Tom was looking for contributors. As a testament to the power of crowdsourcing, Zero Interesting Ways to Use Audio In Your Classroom is now 20 Interesting Ways to Use Audio In Your Classroom. The crowdsourcing hasn’t stopped yet. If you have ideas to add to the slideshow, contact Tom.
