I t is not uncommon to hear a student blame a teacher for a low grade in a course, but the implications of such comments are not always addressed. Incidentally, these occurrences provide insight into where the student believes the control of reinforcement over an outcome exists. Within the framework of social learning theory, Rotter (1966) introduced generalized expectancies for internal versus external control of reinforcement, which refers to the belief or expectation that control of reinforcement for future outcomes exists primarily within oneself or in external sources. For example, individuals with a prototypical internal locus of control perceive a direct link between their actions and the rewards and punishments they incur in day-today life. Individuals with a prototypical external locus of control believe that rewards and punishments vary with external sources, such as luck, fate, or powerful others. The construct of locus of control has enjoyed widespread attention in the scientific literature, which logs a compelling record of its usefulness. An internal locus of control is often tied to greater academic performance (Carden, Bryant, & Moss, 2004). One explanation for this pattern of data is that students with an internal locus of control perceive a link between their behavior and control over the reinforcement, which makes them more likely to put forth the effort to do well. Logically, their external counterparts are less consistent in their academic efforts because the reward for the behavior is expected to come from external sources. For example, Trice and Hackburt (1989) examined the relationship between academic locus of control and college absenteeism. The researchers measured students' locus of control, and then asked students to keep diaries for 6 weeks, in which they recorded absences and noted whether those absences were illness-related. There was a significant correlation between an external locus of control score and absences unrelated to illness. Furthermore, Gump (2004) established a strong negative relationship between absences and course grade. These data lay credence to the claim that an internal locus of control is characteristic of effortful students who are more likely to perform better academically. When students believe the reward will become from internal sources (as opposed to external ones), they are more likely to do what is necessary to perform well (e.g., attend class). Thus, an internal locus of control
