5.2.2. Self-concept in mathematics
Self-concept in mathematics was assessed with a French translation of the Self-Concept in Mathematics Questionnaire (SCMQ) from Efklides and Petkaki (2005). The SCMQ was adapted from a questionnaire designed to tap children's self-concept in the language course (see Dermitzaki & Efklides, 2000 for a study of the reliability and validity of the questionnaire). This 22-items scale measures four dimensions of self-concept namely, self-perception (i.e., the cognitive aspect of self-concept; “I think I am good in math”), self-esteem (i.e., the affective aspect of self-concept; “I am satisfied with my abilities in math”), self-efficacy (i.e., expected success in math tasks; “I expect I will do great this year in math”), and other's perception of the pupil's ability (namely, teachers and classmates; “my classmates often ask to see how I deal with math exercises”). Responses were given on a 5-point scale from 1 (it does not at all apply to me) to 5 (it definitely applies to me). As the aim of our study was to examine the contribution of self-concept on emotion experienced after the task we did not include the other's perception subscale in the analysis because it refers to a different construct. Moreover, Pearson product-moment correlation results indicated the self-esteem subscale was weekly correlated to self- perception r ¼ .39 and to self-efficacy r ¼ .40 whereas the corre- lation between the self-perception and self-efficacy subscales was r ¼ .77. Therefore, in order to increase the homogeneity of the measure, we computed a total score with the self-perception and self-efficacy scales only. Cronbach's alpha for the reduced scale was
a ¼ .90.
