Baker et al (2006) defines gaming the system as "Attempting to succeed in an interactive learning environment by exploiting properties of the system rather than by learning the material".

Within intelligent tutoring systems such as Cognitive Tutors, this is usually done by systematic guessing, where a student systematically tries a set of possible answers (example: 1, 2, 3, 4, 5, ... 38) or hint abuse, drilling through hints at high speed to obtain the answer (Aleven & Koedinger, 2000).

Gaming has been observed in other types of learning environments as well, including educational games (Miller, Lehman, & Koedinger, 1999; Magnussen & Misfeldt, 2004; Rodrigo et al, 2007), simulation environments (Rodrigo et al, 2007), and graded-participation newsgroups (Cheng & Vassileva, 2005).

It has been repeatedly shown that students who game the system have poorer learning than non-gaming students with comparable pre-test scores (Baker et al, 2004, 2006; Walonoski & Heffernan, 2006a). (One exception is when students drill through hints, and then self-explain them -- Shih et al, 2008; another exception is when students game time-consuming material they already know -- Baker, Corbett & Koedinger, 2004).

Gaming the System has been shown to be associated with the affective experiences of boredom and confusion (Rodrigo et al, 2007) -- in specific, a student who experiences either of these two affective states is significantly more likely to be gaming the system shortly afterwards. Frustration, though previously found to be associated with gaming (Baker et al, 2008), appears to co-occur with gaming behavior rather than preceding it.

A variety of stable or semi-stable student characteristics have been studied in relation to gaming the system (e.g. Arroyo & Woolf, 2005; Baker et al, 2008; Beal, Qu, & Lee, 2009); however, these characteristics have generally been found to have weak correlations with gaming, at best. Some characteristics found to be significantly associated with gaming include negative attitudes towards computers, the learning software, and mathematics. Performance goals and anxiety have been repeatedly found to have no correlation to gaming (Baker et al, 2008).

Recent results from PSLC project How Content and Interface Features Influence Student Choices Within the Learning Space indicate that differences between tutor lessons explain much more of the variance in how much students choose to game, than individual differences between students. This finding was obtained through an ANOVA conducted at each of these two levels, and was replicated in both the middle school Cognitive Tutor (precursor to Bridge to Algebra) (Baker, 2007), and the Algebra Cognitive Tutor (paper in preparation).

Further data mining analysis (paper in preparation) using the Cognitive Tutor Lesson Variation Space (CTLVS) showed that students game the system more on lessons which have features which are likely to increase student confusion (including hints which do not lead any students to better performance, reference to abstract principles in hints, whether the toolbar is unclear, and the same number being used for multiple constructs) and boredom (including time-consuming problem steps and the lack of interest-increasing text in problem statements). These results conform well to the previous evidence on which affective states are associated with gaming.

Scooter the Tutor is a software agent who responds to gaming the system with emotional expressions and supplementary exercises (Baker et al, 2006). Scooter was associated with significantly reduced gaming, and significantly improved learning for gaming students (specifically those who received supplementary exercises). Scooter was built on top of the gaming detector, software validated to automatically detect gaming in running Cognitive Tutors (Baker et al, 2008).
