Walkie Charles's Powerpoint

Here's a link to Professor Charles's powerpoint.

It describes how DA allowed Professor Charles to change the way that Arnold was able to learn his heritage language, Yugtun, but it also describes how the process of DA allowed Arnold to change the way that Professor Charles assessed him.  In particular, the process of interventionist DA was not working very well with Arnold, so Professor Charles was steered into using a more interactionist version of DA.  This feedback loop, where the student and the teacher are teaching each other is the power of dynamic assessment, and is the reason why we aren't in any danger of making teachers obsolete.
