From The Chron­i­cle of High­er Edu­ca­tion’s “Wired Cam­pus” Blog:

“Cole W. Cam­plese, direc­tor of edu­ca­tion-tech­nol­o­gy ser­vices at Penn­syl­va­nia State Uni­ver­si­ty at Uni­ver­si­ty Park, prefers to teach in class­rooms with two screens — one to project his slides, and anoth­er to project a Twit­ter stream of notes from stu­dents. He knows he is invit­ing dis­trac­tion — after all, he’s essen­tial­ly ask­ing stu­dents to pass notes dur­ing class. But he argues that the addi­tion­al lay­er of com­mu­ni­ca­tion will make for rich­er class dis­cus­sions…

Once stu­dents warmed to the idea that their pro­fes­sors actu­al­ly want­ed them to chat dur­ing class, stu­dents begin float­ing ideas or post­ing links to relat­ed mate­ri­als, the pro­fes­sor says. In some cas­es, a shy stu­dent would type an obser­va­tion or ques­tion on Twit­ter, and oth­ers in the class would respond with notes encour­ag­ing the stu­dent to raise the top­ic out loud. Oth­er times, one of the pro­fes­sors would see a link post­ed by a stu­dent and stop class to dis­cuss it.
