Concept Maps

Concept maps have these advantages: (1) they simplify difficult to understand or complex topics by lessening the words; (2) they graphically depict the simplest or, at least most fundamental relationships between the limited concepts; (3) it provides simpler modules that can be connected to modularly study the parts of a model

Here is a comparison of concept mapping software by SPT researcher, Dr. Curt McNamara.

Here are some simple concept maps of SPT done originally by McNamara.
