摘要:AbstractNowadays, critical thinking and motivational factors affecting it, such as self-efficacy have been heavily regarded by higher education systems. This descriptive-correlation study aimed to investigate the relationship between students’ self-efficacy and critical thinking in Ferdowsi University of Mashhad, Iran. A random sample of 216 students completed Sherer et al.’s (1982) General Self-efficacy Scale and the California Critical Thinking Skills Test- Form B (1994). Finding showed a significantly positive relationship between students’ self-efficacy and critical thinking (r= 0.21, p< 0.001). Hence, self-efficacy as motivational factor should be considered for developing learners’ critical thinking skills.
