q2 i? The article changes the meaning of "correctness" of an equation and the method of determining which equations it can be derived from, and evaluates the effect of the changed method on the Andes tutor's effectiveness. → Joel A. Shapiro 2005

q2 · i? · design · r?

The abstract identifies "An important change from a previous approach" in the correctness meaning and derivation method, and states the paper evaluates "how the capabilities of the subsystem have affected the Andes tutor's effectiveness, with a particular emphasis on the effects of the changed method".

"An important change from a previous approach is in the meaning of "correctness" of an equation and in the method of determining which equations it can be derived from."
