Abstract
It is common practice to compare gain scores in order to determine the effectiveness of adding features to a training system. Here we argue that relying on one measure of overall system effectiveness may result in overlooking valuable lessons available from a comparison of different versions of a system. To illustrate our point, we present the results of comparing a Natural Language Processing (NLP) based adaptive feedback system to a system that does not utilize NLP capabilities. We show that, while there were no learning gain differences between the two systems, the correlates to gain were different. In the non-NLP system, only student performance during the training was correlated to learning gain. In the adaptive system, more variables correlated with learning, including measures of system capability and student satisfaction. This level of analysis suggests that the two systems are not equivalent and points us towards modifications that may improve effectiveness.
