Daf and Letiticia's Chat in EFL/ESP
One concern some participants raised was how long it took to get the students familiar with the technology, or if a whole separate course might not be needed to teach them the tech skills. From my perspective as a participant, the students readily used the Powerpoint and voice chat interface with little problem, and indeed, these are not difficult technologies to master-as-you-go.
Most impressive was the pre-planning: creating jigsaw task groups where students had to share knowledge with each other, planning how the voice chats would work with the global participation of Webheads, and setting up rubrics for assessment.
Also impressive was the enthusiasm with which the students took on the tasks of creating presentations, taking turns presenting the slides, and conversing with the FL teachers who participated in the voice chats. (Obviously, I can't write about this presentation without drawing on my own side of the experience.)
When discussing the challenges, Daf exclaimed: I went from madness to exhilaration!
