“…Because selfefficacy refers to believing in one's own capability to perform chosen tasks, this belief influences choice of activities, degree of effort expended, and persistence of effort (Bandura, 1986). Theoretical and empirical evidence suggest that self-efficacy might serve as a very powerful construct for predicting behavior and task performance (e.g., Barbeite & Weiss, 2004;Bilgin, Karakuyu, & Ay, 2015;Diseth, 2011;Jackson, 2002;Luszczynska, Scholz, & Schwarzer, 2005;Ogan-Bekiroglu & Aydeniz, 2013;Saçkes, Trundle, Tuckman, & Krissek, 2012). Bandura (1997) further points out that a mastery experience constitutes a major source of self-efficacy in that it generates confidence in having the raw knowledge, skills, and experience to successfully reach a goal or complete a task.…”
