The good bit of this post is the emphasis on voice in online learning. However, it's framed in an odd way. "Almost all online learning involves just clicking," says Donald Clark. This isn't true of any of the online learning I've either given or taken. Is there any online learning with no video, no assignments, nothing but clicking? He also says, "in real life, we don’t click, we speak and listen. Most actual teaching and training uses voice." First of all, computers are real life. Second, I've had a lot of 'real' learning that's far less interactive than online - especially courses based almost entirely on (paper-based) reading. Again - there's no denying the efficacy of voice. That's why I give talks, create podcasts, give interviews.
