It seems to be particularly important for the teacher to explicitly exhibit support for students in their academic pursuit because of their relatively greater influence on the adolescents, as demonstrated in the present analyses. After all, among all others in a school setting, the feedback of teachers is probably the most salient reinforcer regarding student proficiency in academic work. The finding in support of the teacher as a powerful source of reinforcement is not surprising.

the findings of the present study show that the teacher, like all the other significant others considered here, had substantial impacts on adolescents' academic achievement, academic self-esteem, and interest in academic work. Being probably the most significant of significant others in a school setting, the teacher had noteworthy influences on these educational outcomes that were consistent across Grades 5 and 6 and all levels in the high school. More importantly, support from the teacher had even stronger influences than other sources such as parents and peers. The impacts were so strong that they were even greater than the impact of personal expectancy which was presumably the most powerful predictor of these educational outcomes
