I still want to believe in the hype about all these newfangled methods of engaging students in the classroom. Whether it's by using infocomm tools; or peer teaching; or new methods to engage the "21st Century learner"; or this discovery approach (it's not a bad way of looking at the TLLM stuff we keep hearing about, actually); I'm grateful for them all. I cannot imagine how I could possibly do my job if I were a teacher 20-30 years ago with no reliable access to the 'net.
But there are times when you really have to get medieval. Whatever we believe of the "guide on the side", always leave the door open for the sage to take back the stage. Rawr!
