Using perceived group leaders trained to argue for an extreme position, this study examined the function and influence of argumentativeness on leadership perception, leadership maintenance, and decision‐making in the small group. The data suggest that degree of argumentativeness influences perceptions of leadership, with the highly or extremely argumentative individual chosen over the moderate or mildly argumentative individual. Highly argumentative individuals were also rated as more influential on the group's decision. Extremely argumentative individuals, though downgraded in group ratings on “Influence,” were found to have had a disproportionate influence on the group's decision. Implications for small group communication research are discussed.  相似文献

A FIPSE-funded project was designed to provide support and training to community college faculty electronically, and to develop a model to offer innovative, interactive strategies to support their students' academic and career needs. The goal of the mentoring/coaching program has been to support instructors in their online efforts, provide resources and assistance to students, and create a community of learning for all. The examination of the process was framed and guided by the concept of social presence theory. Data collected included mentors' weekly logs, researcher-generated weekly prompts, and bi-monthly focus groups. All data were analyzed qualitatively using open and axial coding. Results indicate that creating social presence may depend, in part, on having an authentic, clearly defined role. Reflections throughout the process required continuous revisions to the plans.  相似文献

A correlational study examined relationships between socioeconomic advantage, achievement motivation, and academic performance in an urban elementary school population of 130 minority students (African-American, Hispanic). Level of socioeconomic advantage (more/less) was determined by school records and eligibility for participation in a compensatory school-lunch program for low-income children. A self-report measure of students' self-efficacy, intrinsic value, and self-regulatory learning orientation was used to determine level of achievement motivation (high/low). Performance data in reading and mathematics were obtained from an individually administered achievement test. Multivariate analyses revealed that socioeconomic advantage and achievement motivation are significant mediators of academic performance in minority children, independent of intellectual ability. The classroom implications of socioeconomic advantage and achievement motivation on individual differences in academic performance of minority children in urban elementary schools are discussed.  相似文献

The use of big data has become the topic for discussion in many executive‐level meetings. Managers and administrators look at top‐flight companies and their successful competitors with envy, because a small number have learned to exploit large amounts of data to become more effective and efficient in their operations. Yes, large amounts of information can improve a company's performance. But first there must be a change in the organization's decision‐making culture.  相似文献
