This study examined the mutual influence of relatively stable personal competence and value beliefs and lesson specific appraisals of competence and value on daily emotional experiences of students in the classroom context. Personal competence and value beliefs were measured by means of questionnaire whereas appraisals and daily emotions were assessed by means of diary forms completed over a two-week period. Multilevel analyses of data from 120 grade seven students revealed that both personal competence-value beliefs and appraisals played an important role in determining daily emotional experiences in the classroom. More importantly, the results showed that the effects of stable personal variables on daily emotional experiences were mediated by lesson specific appraisals. In general, the results support cognitive mediational models of emotion that capitalize on the importance of both personal and situational characteristics in emotion elicitation.
