ABSTRACTOnline interaction has been associated with positive outcomes, academically and psychologically. Regarding the latter, social connectedness has been recognised as an important outcome on the basis of its link to subjective well-being and course satisfaction. In adult educational settings, how online interaction can foster social connectedness has not been widely examined. The study investigates how (1) adult learners’ online participation operationalised as discussion contribution, collaborative facilitation, and social interaction, and (2) their perceived online interaction quality are related to their feeling of social connectedness. The role of online interaction quality related to the three types of online participation and social connectedness is also examined. A questionnaire was developed to collect data from adult learner participants in Belgium (N?=?170). Multiple regressions and mediation analysis were conducted. The result shows that collaborative facilitation and online interaction quality significantly contribute to adult learners’ perceptions of social connectedness. Furthermore, the finding reveals that online interaction quality fully mediates the relationship between discussion contribution, social interaction, and social connectedness. Thus, the implications for research and instructional design are discussed. 相似文献

ABSTRACT This paper reports the results of a one‐year project designed to develop the awareness of 291 student teachers in the area of electronic mail (e‐mail). The project was successful in increasing the active use of e‐mail and the general awareness of students: the number of active users rose from 17 to 33%, and the number of those able to explain e‐mail to a colleague rose from 12 to 45%. Case study material is presented to illustrate the conditions under which the development of e‐mail flourished with one particular group of modern languages student teachers. Conclusions are drawn concerning the utility of the cascade model of curriculum development in extending electronic communication. 相似文献

A full bibliography on one of the most active areas of broadcasting —CATV—is long overdue. Don Le Duc originally prepared this compilation while working on his doctorate at the University of Wisconsin. It is based on an extensive clipping file collected by Kenneth Lichty of India, California, and by the author's major professor, Lawrence W. Lichty of the University of Wisconsin. Support for completing the collection came, in part, through a fellowship awarded by the Department of Communication Arts and a travel grant from the Graduate School of Arts and Sciences of the University of Wisconsin. Dr. Le Duc is a member of the State of Wisconsin and United States Supreme Court Bars, and is on the publications committee of the Federal Communications Bar Association and the communications committee of the American Bar Association. Formerly on the faculty of the University of Maryland, he will be assistant professor in the Department of Speech at the Ohio State University starting this fall. 相似文献

We experimentally investigate the effects of high electric field on living cells inside a charged droplet under electrophoretic actuation. When an aqueous droplet suspended in a dielectric liquid contacts with electrified electrode, the droplet acquires charge. This charged droplet undergoes electrophoretic motion under strong electric field (1–3 kV/cm), which can be used as a droplet manipulation method in biomicrofluidic applications. However, because strong electric field and use of dielectric oil can be a harmful environment for living cells, the biological feasibilities have been tested. Trypan blue test and cell growth test have been performed to check the viability and proliferation of cells in a droplet under various electric field strengths and actuation times. We have not observed any noticeable influence of electric field and silicone oil on the viability and proliferation of cells, which indicates that electrophoresis could be safely used as a manipulation method for a droplet containing living biological system. 相似文献

ABSTRACTDrs Abhijit Banergee, Esther Duflo, and Michael Kremer won the 2019 Nobel Prize in Economic Sciences for their remarkable series of large-scale field experiments to lessen global poverty. The main theoretical framework that they employed was the diffusion of innovations research and practice paradigm (DOI) which has had a long presence in communication research dating back to the 1940s. Here, we reviewed the Nobel laureates’ article, ‘Using gossips to spread information: Theory and evidence from two randomized controlled trials,’ that is illustrative of how economists applied the communication theory of diffusion of innovations to their projects of social change. The present article poses questions and makes recommendations for similar future projects from a communication perspective. 相似文献

Objective: To analyse the effect of resistance training (RT) frequency on muscle mass, appendicular lean soft tissue, insulin-like growth factor 1 (IGF-1), testosterone, and their changes with detraining in older women. Methods: Forty-five physically independent older women (≥ 60?years) were randomly assigned to perform RT either two (G2X, n = 21) or three times/week (G3X, n = 24), during 12?weeks (8 exercises, 1 set of 10–15 repetition maximum). Muscle mass and appendicular lean soft tissue, IGF-1, testosterone, and dietary intake were measured at pre-training, post-training, and after detraining (12?weeks). Results: Muscle mass and appendicular lean soft tissue significantly increased post-training (G2X?=?+5.5% and G3X?=?+5.8%, P?P?P?Conclusion: We conclude that lower RT frequency is as effective as higher frequency to improve muscle mass and appendicular lean soft tissue, and to maintain testosterone and IGF-1. Additionally, detraining may reduce testosterone regardless of RT frequency. These results are specifically for community-dwelling older women and may not be generalized to other populations. 相似文献

This paper assesses and compares the prevalence of plagiarism across different student and assignment characteristics at a university in Vietnam, using the similarity index reported by the text-matching software Turnitin as a proxy measure of plagiarism on a sample of 681 student papers. The findings present a level of match higher than reported in earlier studies at universities outside of Vietnam, with an average similarity index of 29.06%. Controlling for the gender and major of the students, the extent of plagiarism is implied to be negatively correlated with the students’ academic performances and with the likelihood of being caught, and positively correlated with the length of the assignments. Thus, this study, relying on actual text-matching data rather than self-reported surveys, provides the first empirical test of two theoretical plagiarism models proposed in the literature. The explanatory factors confirmed by this study illustrate the potential benefits of the use of software tools to detect plagiarism and can help refine academic integrity policy formulations for universities. 相似文献

As an emergent theme in educational research, examination of the lives and careers of teachers reveals a wide range of educational factors occurring in many different contexts. Despite the relationship between teaching and life outside school, research studies have been inclined towards the working aspects of teachers’ lives. Rather than following the predominant model in the research literature, this study focused on teachers’ lives in the broader sense exploring the life tensions faced by teachers of English language in Vietnamese primary schools. Drawing on narrative inquiry as a research approach, data were collected from interviews conducted with six participating teachers. The findings indicated that the participants, similar to the majority of Vietnamese teachers, were involved in struggles over living conditions. As a result of the low pay they received for their teaching jobs, they engaged in private tutoring to bolster their income to adequately support themselves and their family. As language teachers, the participants used the English language for access to other cultures but they lived under pressures caused by cultural differences. Along with depicting the lives of Vietnamese teachers, the study offers suggestions to education leaders and educational researchers on how the situation might be alleviated. 相似文献
