Why a Diagram is (Sometimes) Worth Ten Thousand Words
TLDR
This work distinguishes diagrammatic from sentential paper-and-pencil representationsof information by developing alternative models of information-processing systems that are informationally equivalent and that can be characterized as sentential or diagrammatic, and contrasts the computational efficiency of these representotions for solving several illustrative problems in mothematics and physics.

Expert and Novice Performance in Solving Physics Problems
Although a sizable body of knowledge is prerequisite to expert skill, that knowledge must be indexed by large numbers of patterns that, on recognition, guide the expert in a fraction of a second toExpand

Models of Competence in Solving Physics Problems
TLDR
A set of two computer-implemented models that solve physics problems in ways characteristic of more and less competent human solvers are described, providing a good account of the order in which principles are applied by humansolvers working problems in kinematics and dynamics. Expand
