A series of studies present the development and validation of the Communication Anxiety Regulation Scale (CARS), a self-report measure designed to assess the use of emotion regulation strategies to manage acute communication anxiety—in contrast to measures of general emotion regulation tendencies. Study 1 delineates the item derivation and selection process that yielded the final 12 CARS items. Results of an exploratory factor analysis supported the existence of four distinct subscales, each representing one of four anxiety regulation strategies (suppression, reappraisal, avoidance, and venting). Study 2 confirmed this factor structure and also examined correlations of the CARS with existing measures in an attempt to establish concurrent validity. Finally, Study 3 presents results of an item-sort task demonstrating the scale’s face validity and items’ substantive validity. Overall, findings provide preliminary support for the utility of the CARS as measure of communication anxiety regulation to be used by communication and psychology researchers. 相似文献

There is much current debate about the purpose and usefulness of educational research and the perceived communication gap between teaching professionals and academic researchers. UK government intervention into initial teacher education has in recent decades contributed to this divide by favouring school-based training. The most common route into teaching in England remains, however, the Postgraduate Certificate in Education, provided by higher education institutions and therefore required to comply with the higher education qualifications framework. The majority of initial teacher education in England therefore lies at the cusp of these two worlds, pulled in apparently opposing directions. The ‘teacher-as-researcher’ movement is widely seen as a bridge spanning these tensions, though there is discussion about the quality of practitioner research as well as about the appropriateness of a rigorous academic approach for investigating practice. This article offers examples of the use of small-scale research projects as a valid means of ‘discovery learning’ in pre-service teacher education. It argues that induction into research techniques as a means of exploring practical challenges can lead to knowledge production and ownership. 相似文献

Computer-based multimedia presentations employing animated agents (avatars) can positively impact perceptions about engineering; the current research advances our understanding of this effect to pre-college populations, the main target for engineering outreach. The study examines the effectiveness of a brief computer-based intervention with animated agents in improving perceptions about engineering. Five hundred sixty-five elementary, middle-, and high-school students in the southwestern USA viewed a short computer-based multimedia overview of four engineering disciplines (electrical, chemical, biomedical, and environmental) with embedded animated agents. Students completed identical surveys measuring five subscales of engineering perceptions immediately before and after the intervention. Analyses of pre- and post-surveys demonstrated that the computer presentation significantly improved perceptions for each student group, and that effects were stronger for elementary school students, compared to middle- and high-school students. 相似文献

The 2008 Educational Policy and Accreditation Standards identified 10 core competencies that all social work graduates should master. MSW programs found themselves with a need to identify knowledge, values, and skill statements that reflected what concentration-year students were expected to know and be able to do. In 2009 a group of educators convened at the Council on Social Work Education in Alexandria, VA to develop a model of advanced practice in clinical social work. This article describes the work group's process; identifies and describes the resulting advanced clinical knowledge, values, and skills statements; discusses the key debates and issues that arose during the development of the statements; and concludes with the implications for social work education and practice. 相似文献

This study aimed to analyse fatigue-induced changes in mechanical sprinting properties during a specific repeated-sprint test in elite rugby sevens athletes. Twenty elite rugby sevens players performed ten 40?m sprints on a 30?s cycle with participant’s running back and forth in a marked lane. Radar was used to assess maximal overground sprint performance over each 40?m. Macroscopic mechanical properties (maximal horizontal force (F0), maximal horizontal power (Pmax), maximal ratio of horizontal force (RFpeak), decrease in the ratio of horizontal-to-total force (DRF), total force and maximal sprinting velocity (v0)) were drawn from horizontal force velocity relationships, using a validated method applied to the speed–time data. Fatigue-induced changes were analysed comparing the first sprint to an average of 2nd-4th, 5th-7th and 8th-10th. Repeated-sprint ability (RSA) testing induced substantial changes in the maximal velocity component, with a decrease (–15%) in v0 (effect size (ES)?=?–2.46 to –4.98), and to a lower extent (–5.9%) in the maximal force component F0 (ES?=?–0.59). DRF moderately decreased (14%; ES=–0.76–1.11), and RFpeak largely decreased in the later sprints (ES?=?–0.32 to –1.27). Fatigue observed in this RSA test appeared to have a greater effect on the technical ability to produce horizontal force at high velocities, likely due to an alteration in the ability to maintain horizontally oriented force application when velocity increases rather than during the initial acceleration phase, but also the overall force production capacity. The ability to maintain forward-oriented force at high velocities is of central importance for identifying fatigue and monitoring load. 相似文献
