Reading Malcolm Gladwell gives insight into how to reach kids with interesting things in our TPRS classrooms. (We now know that “interesting things in the TPRS classroom” means anything that has to do with them – such is their age…).
Gladwell talks about improvisation on pp. 114-116 of his book Blink. (We also now that, if our stories are to interest our kids, we must be improvisers.) Improvisation, in my mind, is the “letting the water flow downhill” version of TPRS, where information about the story is allowed to emerge naturally so that the interest is genuine, having been generated, again, by and about them.
