This study examines how good strategies and praxis interplay with positive affect and self-efficacy to determine a teacher's job satisfaction, in the hypothesis that teaching effectively does not in itself guarantee satisfaction: positive affect and self-efficacy beliefs are needed. Self-assessment scales, designed to assess the use of efficient teaching strategies and praxes, self-efficacy in teaching, positive affect and job satisfaction, were completed by 399 teachers. Structural equation modelling (SEM) analysis revealed the mediating role of both positive affect and self-efficacy beliefs in the relationship between teaching strategies/praxes and job satisfaction.
