Visualization and Illusion of Explanatory Depth

Might be useful to take advantage of this for teaching/explaining:

"People also seem to use misleading heuristics to assess how well they understand a system. Most notably, if they can see or easily visualize several components of a system, they are more convinced they know how it works. Thus, the more easily visible are parts in a system, relative to hidden ones, the stronger the IOED (Rozenblit & Keil 2002). Visual influences of this sort may be related to the appeal of visual “mental animations” in constructing and evaluating explanations of devices (Hegarty 1992)."

From Keil, 2006; Explanation and Understanding

Explanation as a learning strategy

Tamar: This would be an easy manipulation in the sim.  Compare feedback vs. feedback and explanation.

An effective meta-cognitive strategy


Meta-analysis, Similarity, and Hierarchy

Kind of interesting.  Generalization can be based on hierarchies (categories) or similarities.  I've thought about trying to come up with some similarity metric for meta-analysis, where studies are obviously more or less similar to each other, but not categorically related, or at least the hierarchies are extremely sparse (most categories have zero instances).

Properties of inductive reasoning

The structure and function of explanation

Explanation during IHD simulation

Tamar: Fonseca and Chi: if they explain themselves during a learning task they learn better than those who think out loud, especially going beyond presented material. Might be neat for IHD sim.  Might need to come up with tests that are `far transfer'.
