What is Variable Features

Task persistence is defined as the continuation of activity in the face of difficulty, obstacles, and/or failure. It has been linked to educational achievement, educational attainment, and occupation outcomes. A number of different psychological approaches attempt to explain individual and situational differences in persistence and there is mounting evidence that interventions can be implemented to increase persistence. New technological capabilities offer the opportunity to seamlessly gather evidence about persistence from individuals' interactions in digital environments. Two examples of assessment of persistence in digital games are presented. Both demonstrate the ability to gather information without interruption of activity and the use of in-game actions as evidence. They also both require consideration of the student/player model, task model, and evidence models. A design pattern outlining each of these elements is presented for use by those considering assessment of persistence in digital environments.
