“…It includes three dimensions: character (trustworthiness), competence (intelligence), and caring (goodwill) (McCroskey, 1972; Teven & Katt, 2016). Credibility has been described as a “super-variable” (Teven & Katt, 2016, p. 184) because of its relationship to many facets of classroom dynamics and teacher-student relationships (McCroskey et al, 1974; Nadler & Nadler, 2001), including what students believe they learn (Gili, 2013; Myers & Martin, 2006; Russ et al, 2002; Teven & McCroskey, 1997), and student evaluations of instructors (Boren & McPherson, 2018; DeSouza & Olson, 2018; Russ et al, 2002; Teven & McCroskey, 1997). Further, students who do not trust an instructor are unlikely to invest in learning (Teven & Katt, 2016); yet, students who perceive an instructor to be highly credible are likely to recommend that faculty member to a friend and register for another course taught by the same instructor (McCroskey et al, 1974; Nadler & Nadler, 2001).…”
