In short, two teachers share teach together in two different classrooms 150 miles apart. The collaborative duo pull off this feat with the use of Google Hangouts and PearDeck. They each use two projectors in their respective classrooms; one projects the Pear Deck presentation, while the other projects the students from the other classroom 150 miles away.
While I don’t plan to use this technique in my immediate future, it does open up more possibilities for distance learning. Since anyone globally can enter an open Pear Deck presentation if he has the PIN code, a teacher could instruct countless students at one time. Pear Deck and hangouts provide a platform to merge the worlds of traditional classroom instruction and pure online instruction together. You get the benefit of face-to-face human interaction through Skype and Hangouts while being able to continue education from hundreds–or thousands–of miles away.
