“…The origins of trust research drew from the work of Rotter (1967) and others who identified the importance of interpersonal trust and the extent to which learners believe in the trustworthiness of their sources of information—that is, teachers and materials. Those early conceptualizations have broadened considerably in the past 30 years through several significant lines of research that have examined trust and related constructs at the individual and collective levels, in relation to different referents (students, parents, teachers, principals, schools) and in relation to student achievement (e.g., Bryk & Schneider, 2002; Hoy, Gage, & Tarter, 2006; Hoy & Tarter, 2004; Hoy, Tarter, & Hoy, 2006; Hoy, Tarter, & Witkoskie, 1992; Kensler, Caskie, & White, 2009; Seashore Louis, 2007; Sutherland & Yoshida, 2015; Tschannen-Moran, 2001, 2003, 2009). This research has offered a great deal of insight into the social and cultural dynamics of school ecologies, and concepts such as teacher trust in client (Forsyth, 2008) and academic optimism (Hoy et al, 2006) have demonstrated greater potential at predicting student achievement than SES.…”
