Refinement of the Classroom Citizenship Behavior Scale

In its original presentation, scores on two of the three subscales of the Classroom Citizenship Behavior scale were highly reliable. Scores on the subscale measuring the third dimension of classroom citizenship behavior, Courtesy, had poor reliability. We inductively derived additional items for the Courtesy subscale and tested structure and reliability of the revised scale. Exploratory factor analysis indicated that the scale readily divided into three factors of six items each, consistent with the proposed model. Furthermore, the subscale scores associated with these factors demonstrated high reliability. Next, two additional communication classes completed the revised scale and confirmatory factor analyses were run on the new version of the three-factor scale. Fit indices were good. The revised Classroom Citizenship Behaviors scale provides a stronger tool for investigating student behaviors that contribute to the effective functioning of the classroom environment.     

Effects of Instructor Speech Rate on Student Affective Learning,Recall, and Perceptions of Nonverbal Immediacy,Credibility, and Clarity

Although research indicates that speech rate affects perceptions of speaker credibility as well as persuasiveness and information recall, research has failed to address how instructor speech rate affects student perceptions and learning. This study randomly assigned basic communication course students to one of three speech rate conditions (slow, moderate, fast), using a videotaped lesson by an instructor. Findings revealed significant differences for credibility, affective leaning, and nonverbal immediacy, but did not reveal significant differences for recall or clarity. Implications for instructional practice and suggestions for future research are discussed.     

The Influence of Emotional Contagion on Student Perceptions of Instructor Rapport,Emotional Support,Emotion Work,Valence, and Cognitive Learning

This study examined how emotional contagion may influence student perceptions of rapport with the instructor, emotional support received in the classroom, emotional work performed, and perceived cognitive learning. Participants revealed that emotional contagion was positively related to perceptions of rapport with instructors but unrelated to emotional support from instructors, emotional work performed in the classroom, and valence. Students who were high in emotional contagion reported significantly more rapport, emotional support, and positive valence. When controlling for emotional contagion, only classroom valence predicted students’ perceptions of cognitive learning.     

Assessing the Effects of Instructor Enthusiasm on Classroom Engagement,Learning Goal Orientation,and Academic Self-Efficacy

Enthusiasm is widely regarded as one of the most essential and desirable qualities and characteristics of effective teachers. This study is designed to assess the effects of teacher enthusiasm on student classroom engagement, learning goal orientation, and academic self-efficacy. Participants include 165 college students enrolled in basic communication classes. Results indicate that teacher enthusiasm is an effective predictor of student behavioral, cognitive, and emotional engagement, intrinsic goal orientation, and academic self-efficacy, but it is not a significant predictor of extrinsic goal orientation. Consequently, this study demonstrates the power of teacher enthusiasm in predicting and shaping students' behavior in the classroom.     

The Effects of Social Support,Depression, and Stress on Drinking Behaviors in a College Student Sample

Social support research contends that supportive interactions provide a buffer wherein individuals are protected from increased risk due to negative affect. The present study investigated the relationships between social support and college students' stress, depression, and alcohol use. A total of 54 students completed questionnaires in exchange for extra course credit. Results demonstrated that stress and depression were correlated with one another and that social support was negatively correlated with each of these outcomes. Depression, but not stress, was correlated with increased drinking behavior. Overall, social support was negatively correlated with alcohol consumption; however, depression moderated the effect of social support such that support and alcohol consumption were negatively correlated for participants with higher depression whereas support and alcohol consumption were positively correlated for individuals with lower depression. These findings partially confirm existing theories of alcohol use that hypothesize differences between self-medicating drinkers and social, sensation-seeking drinkers.     

The Relationship between Student Perceptions of Instructor Power and Classroom Justice This manuscript was presented as part of the Top Paper Panel to the Instructional Practices Interest Group of the Eastern Communication Association at its annual meeting in Pittsburgh, 2005.

The study investigated the relationships between student perceptions of instructor power and classroom justice. Partial correlations controlling for student grade expectations indicated that student perceptions of their instructors’ use of coercive, legitimate, referent, and expert power were related to perceptions of fairness in the classroom. Student perceptions of instructor use of reward power were not related to perceptions of any type of classroom justice.     

Teacher Influence in the Classroom: A Preliminary Investigation of Perceived Instructor Power,Credibility, and Student Satisfaction An earlier version of this paper was presented on a program of the Communication Education interest group at the annual convention of the Central States Communication Association,Milwaukee, WI,April 2002.

The purpose of this study was to examine the relationships between perceived teacher power, teacher credibility, and student satisfaction. Respondents were 67 undergraduate students (30 males and 37 females) enrolled in Communication classes at a southwestern university. Students’ perceptions of their teachers’ expert, referent and reward power use were found to be positively related to their perceptions of their teachers’ competence, caring, and trustworthiness. Teacher power use contributed to the prediction of a significant amount of variance in teacher credibility. Additionally, student satisfaction was positively and significantly related to both teacher referent power and expert power. Surprisingly, students’ perceptions of coercive power were not significantly and negatively related to student satisfaction. Implications, limitations and suggestions for future research are discussed.
