N1 - 10 N2 - Two questionnaires were presented (national evaluation by the Ministry of Education in France, DEPP) to 31,120 students in grade 6 of the French “collège” (11.6 years): a questionnaire referring to self-efficacy (SE) and a motivation questionnaire referring to the self-determination theory (SDT). PCA confirms the three principal factors concerning the SEP: school SE, self-regulation, and social SE. PCA of motivation’s items produce three factors corresponding to intrinsic motivation, extrinsic motivation, and amotivation. The correlations reveal a reconciliation between the theories of Bandura (SEP) and Deci and Ryan (perceived competence) because the school SEP is correlated in a continuum with the forms of motivation (including amotivation). The perceived competence (or school SEP) is the best predictor of cognitive/school tests. Among the forms of motivation, amotivation is associated with the poorest scores on all tests UR - https://shs.cairn.info/journal-bulletin-de-psychologie-2013-1-page-23?lang=en&redirect-ssocas=7080 ER -
