Mentoring is a trusting, developmental supervisory relationship whose success largely depends on participants' interpersonal abilities. Feedback interventions with mentees commonly present interactional challenges to maintaining that relationship, yet are integral to any teaching-learning context. In this study we examined whether and how two…

Instructors routinely provide feedback for students concerning the work the students produce as part of a classroom course. Although such information is required of instructors and expected by students, the communication of feedback creates a potentially face-threatening interaction in which the student's self-esteem may be diminished and/or the…

This study tested two theoretical models of instructor credibility as a potential mediator between instructors' classroom communication behaviors (nonverbal immediacy, enthusiasm, and homophily) and students' intentions to persist in college. Participants included 570 undergraduate students from three institutions in the South-Central United…

This study tested two models of instructor credibility as a potential mediator of instructors' prosocial communication behaviors (e.g., confirmation, clarity, and nonverbal immediacy) and students' learning outcomes. Participants included 1,416 undergraduate students from four different institutions across the United States. Results of structural…

This meta-analysis reviews the findings of 51 studies (N = 14,378) examining the associations among teacher credibility, teacher behaviors, and student outcomes. When all three dimensions of credibility are considered collectively (i.e., competence, trustworthiness, and caring), the cumulative evidence indicates a moderate, meaningful relationship…

This study tested two theoretical models of learner empowerment as a potential mediator of teacher power use and students' ratings of instruction. Participants included 1,416 undergraduate students from four different institutions in the United States. Results of structural equation modeling provided more support for the partial mediation model…

Three studies were conducted to (a) re-examine the internal properties of Roach's Power Base Measure (PBM), (b) test the PBM for measurement invariance across different samples, and (c) develop an alternative measure of observable teacher behaviors that communicate power in the classroom. Results of Studies 1 and 2 provide some support for the…

This study examined the interaction effect of nonverbal immediacy and expected instructional technology use on students' initial reports of instructor credibility. Participants included 549 college students who were randomly assigned to one of eight scenarios depicting first-day class sessions across four levels of technology use and two levels of…

This report uses meta-analysis to derive correlations between the variables of teacher immediacy, cognitive learning, and affective learning. A model was constructed such that the perception of teacher immediacy, a behavior, generates an intermediate outcome of affect, a motivation, which in turn increases cognitive learning outcome. The data…

This investigation included two studies relating anticipatory public speaking anxiety to the nature of the speech assignment. Based on uncertainty reduction theory, which suggests that communicators are less comfortable in unfamiliar or unpredictable contexts, two hypotheses were advanced on the presumption that various types of assignments in a…

Presents a study in which experimental manipulation of combinations of nonverbal and verbal immediacy allowed researchers to more precisely test these causal links in relation to recall, learning loss, and affective learning. Notes that higher verbal immediacy in the experimental manipulations, when combined with higher and lower nonverbal…

Explores the possible relationship between students' expectations for teacher nonverbal immediacy and their enrollment in a distance-learning course. Finds that distance students expected less nonverbal immediacy from telecourse teachers than on-site students expected of their teachers; and that students with previous distance-learning experience…
