Online social networks: Why do students use facebook?   总被引:1,自引:0,他引:1  
The growth and popularity of online social networks has created a new world of collaboration and communication. More than a billion individuals around the world are connected and networked together to create, collaborate, and contribute their knowledge and wisdom. Despite the importance of online social networks, there is relatively little theory-driven empirical research available to address this new type of communication and interaction phenomena. In this paper, we explored the factors that drive students to use online social networks (e.g., Facebook). Specifically, we conceptualized the use of online social networks as intentional social action and we examined the relative impact of social influence, social presence, and the five key values from the uses and gratification paradigm on We-Intention to use online social networks. An empirical study of Facebook users (n = 182) revealed that We-Intention to use online social networks is strongly determined by social presence. Among the five values, social related factors had the most significant impact on the intention to use. Implications for research and practice are discussed.  相似文献

Previous research has identified the importance of social connectedness in facilitating a number of positive outcomes, however, investigation of connectedness in online contexts is relatively novel. This research aimed to investigate for the first time social connectedness derived from the use of Facebook. Study 1 investigated whether offline social connectedness and Facebook connectedness were separate constructs. Participants were Facebook users (N = 344) who completed measures of offline social connectedness and Facebook social connectedness. Factor analysis (Maximum Likelihood analysis with Oblimin rotation) revealed Facebook connectedness to be distinct from offline social connectedness. Study 2 examined the relationship between Facebook social connectedness and anxiety, depression, and subjective well-being in a second sample of Facebook users (N = 274) in a cross-sectional design. Results suggest that Facebook use may provide the opportunity to develop and maintain social connectedness in the online environment, and that Facebook connectedness is associated with lower depression and anxiety and greater satisfaction with life. Limitations and future directions are considered. It is concluded that Facebook may act as a separate social medium in which to develop and maintain relationships, providing an alternative social outlet associated with a range of positive psychological outcomes.  相似文献

Though considerable research has investigated spatial and social presence, little research has examined the influence of self-presence in a mediated environment. The present work is an empirical study of the role of self-presence in a social virtual world on individuals’ offline health, appearance, and well-being. Second Life users (N = 279) completed an online questionnaire about their experiences of presence in the virtual world, the influence of their avatar on their offline appearance and health behaviors, and their level of satisfaction with the relationships they developed online. It was hypothesized that self-presence would be positively associated with avatar influence on health and appearance and that self-presence would render the influence of spatial and social presence statistically non-significant. Additionally, it was hypothesized that self-presence would be positively associated with satisfaction with relationships developed in the virtual world. Support was found for these predictions. Results suggest that self-presence is uniquely linked to the influence of the virtual self on offline health and appearance and is a significant predictor of the development of satisfying online relationships. Individual differences and potential prosocial effects of virtual worlds are also discussed.  相似文献

The purpose of this study was to explore sequences of social regulatory processes during a computer-supported collaborative learning task and their relationship to group performance. Analogous to self-regulation during individual learning, we conceptualized social regulation both as individual and as collaborative activities of analyzing, planning, monitoring and evaluating cognitive and motivational aspects during collaborative learning. We analyzed the data of 42 participants working together in dyads. They had 90 min to develop a common handout on a statistical topic while communicating only via chat and common editor. The log files of chat and editor were coded regarding activities of social regulation. Results show that participants in dyads with higher group performance (N = 20) did not differ from participants with lower group performance (N = 22) in the frequencies of regulatory activities. In an exploratory way, we used process mining to identify process patterns for high versus low group performance dyads. The resulting models show clear parallels between high and low achieving dyads in a double loop of working on the task, monitoring, and coordinating. Moreover, there are no major differences in the process of high versus low achieving dyads. Both results are discussed with regard to theoretical and empirical issues. Furthermore, the method of process mining is discussed.  相似文献

This study investigated the association between trust in individuals, social institutions and online trust on the disclosure of personal identifiable information online. Using the Internet attributes approach that argues that some structural characteristics of the Internet such as lack of social cues and controllability are conducive to a disinhibitive behavior it was expected that face to face trust and online trust will not be associated. In addition, it was expected that from the three components of trust, online trust only will be associated with the disclosure of identifiable personal information online. A secondary analysis of the 2009 Pew and American Life of Internet users (n = 1698) survey was conducted. In contrast with the Internet attribute approach the effect of trust in individuals and institutions was indirectly associated with the disclosure of identifiable information online. Trust in individuals and institutions were found to be associated with online trust. However, online trust only, was found to be associated with the disclosure of personal identifiable information. While trust online encourages the disclosure of identifiable information, perception of privacy risks predicted refraining from posting identifiable information online. The results show a complex picture of the association of offline and online characteristics on online behavior.  相似文献

This study explored the differences among online elementary school student groups based on their communication features. Two hundred and ninety-one Taiwanese students, ranging in age from 11 to 12 years old, participated in this study. The students were randomly arranged within-class into three-member groups. Each group was asked to use a collaborative learning system to accomplish a group task generating a shared concept map. The textual discussions in each group during collaboration were collected, coded, categorized, and quantified to profile their communication characteristics. Cluster analysis on the resulting communication characteristics resulted in four types of small student groups, including passive or reticent, frequently off-task, actively participating, and knowledge emphasizing. Most student groups (56%) were found to be relatively passive or reticent. Frequently off-task student groups made a protrusive amount of messages for off-task social purposes. The actively participating student groups were characterized by abundant discussion, particularly for continuing task, managing procedure and coordinating efforts. The distinctive feature of knowledge emphasizing student groups was that they devoted particular attention to task related knowledge. In addition, they performed better in task accomplishment.  相似文献

As more and more people use computers to complete their work and solve problems in the workplace, computing education is emphasized for students of all levels and disciplines in Taiwan. However, the computing education in Taiwan can hardly be recognized as effective and satisfactory. Many inappropriate examples that lack context are used in teaching and textbooks that may result in employees with low competence and insufficient ability for collaborative working. Students who grow up in this learning context usually lack the ability to seek information and solve problems by themselves. In this regard, the author redesigned a course and adopted online collaborative learning with initiation to establish the essential knowledge for students’ collaboration in the initial stage of a course. This study conducted an experiment that included 169 undergraduates from three class sections – the first two from an academic university (Case 1, n = 68; Case 2, n = 68) and the last one from a university of science and technology (Case 3, n = 33) – taught by the same teacher under the same course name and the same course website. The results show that students who received online collaborative learning with initiation had higher grades than those without. The author further discusses the implications for teachers, schools, and scholars who plan to provide online courses for their students, particularly computing courses.  相似文献

Instant Messaging (IM) plays a major role in online communication, whether through dedicated software or through chat integrated in a social network’s platform. IM-based online conversation enables private, synchronous, interpersonal communication while being invisible and possibly anonymous; facilitates self-disclosure and intimacy; and possesses advantageous features of expressive writing and social support. For adolescents, the use of IM is a legitimate, available, and free alternative vehicle for communicating with peers to ventilate negative emotions and to receive social support and advice. The present study examined effects of IMing friends on the emotional state of distressed adolescents through both pre-post (n = 100) analyses and comparison with an un-distressed group (n = 50). Dependent measures included self-report questionnaires, textual analysis, and expert judges’ evaluations of the conversations. Findings revealed that IM conversation significantly contributed to the well-being of distressed adolescents. In addition, participants’ level of introversion–extroversion moderated the degree of their perceived emotional relief, so that introverted participants profited from IMing more than did extraverts. The implications of these findings are discussed in the context of online communication theory, as well as the practical implementations for troubled adolescents.  相似文献

The present study investigates the influence of Twitter use and the number of followers and followees on perceived bridging and bonding online social capital. Data from a convenience sample of Twitter users (N = 264) indicate that bonding social capital is associated with the number of followers whereas bridging social capital is influenced by the number of followees. Thus, the directed friendship model on Twitter affects different forms of social capital differently. In addition, the study found a negative curvilinear effect of the number of followees on bridging and the number of followers on bonding online social capital. This indicates that the number of followees/followers has positive effects on online bridging/bonding social capital, but only to a certain point. The paper concludes with a discussion of the results in light of theoretical considerations and of implications for future research on the effects of Twitter on social capital.  相似文献

The aim of this study is to test the effects of dynamically scaffolding social regulation of middle school students working in a computer-based learning environment. Dyads in the scaffolding condition (N = 56) are supported with computer-generated scaffolds and students in the control condition (N = 54) do not receive scaffolds. The scaffolds are dynamically adjusted to dyads’ progress with an attention management system. The scaffolds support two aspects of socially regulated learning namely the metacognitive and cognitive activities. We analyzed the effects of dynamic scaffolding on dyads’ performance, their perception of the learning environment and students' knowledge acquisition. We found that scaffolding had a positive effect on the dyads’ learning performance, but did not affect students’ domain knowledge. The repeated measurements of perception of the learning environment showed that dyads in the experimental condition were more positive about their teachers and their collaborators than students in the control condition. With respect to their perception of the software and the 3D embodied agent delivering the scaffolds, we found a stronger decrease of appreciation over time in the scaffolding condition compared to the control condition.  相似文献

The purpose of the current study was to identify potential factors leading to preference for social interaction in online support groups (OSGs) over offline interaction. By identifying such factors, the current study advances understanding of the way patients use the Internet as a supportive resource and integrate support from offline and online relationships. An online survey was conducted with current users of health-related OSGs (N = 158). Findings show that those who were dissatisfied with the support they received from their current offline contacts were more likely to prefer social interaction in OSGs. Such a preference was prominent among those who built deeper social relationships in OSGs. Results suggest that some people develop a preference for social interaction in OSGs over offline interaction and use computer-mediated relationships as a possible alternative to offline support networks. Healthcare professionals and users as well as designers of OSGs must acknowledge the limits of online support and caution against the possibility of developing excessive reliance on online support resources.  相似文献

Online gaming has gained millions of users around the globe, which have been shown to virtually connect, to befriend, and to accumulate online social capital. Today, as online gaming has become a major leisure time activity, it seems worthwhile asking for the underlying factors of online social capital acquisition and whether online social capital increases offline social support. In the present study, we proposed that the online game players’ physical and social proximity as well as their mutual familiarity influence bridging and bonding social capital. Physical proximity was predicted to positively influence bonding social capital online. Social proximity and familiarity were hypothesized to foster both online bridging and bonding social capital. Additionally, we hypothesized that both social capital dimensions are positively related to offline social support. The hypotheses were tested with regard to members of e-sports clans. In an online survey, participants (N = 811) were recruited via the online portal of the Electronic Sports League (ESL) in several countries. The data confirmed all hypotheses, with the path model exhibiting an excellent fit. The results complement existing research by showing that online gaming may result in strong social ties, if gamers engage in online activities that continue beyond the game and extend these with offline activities.  相似文献

The present work, through an ethnographic study of MySpace (N = 96), examines the ways in which authenticity is accomplished within a labor-exposing space. To maintain authenticity, actors must make invisible the extensive labor of self-presentation. Certain online spaces, such as social network sites and personal interactive homepages, can be thought of as labor-exposing spaces, in that they give actors clear and explicit control over self-representations, making impressions of spontaneity difficult to accomplish ( ,  and ). I discuss and delineate several strategies used by participants to maintain authenticity on MySpace. I conclude that while the priorities of identity processes remain stable over time, the ways in which we accomplish identity are culturally, historically and materially contingent.  相似文献

Two studies examined the use of video in multimedia learning environments. In Study 1, participants (N = 26) viewed one of two versions of a computer-based multimedia presentation: video, which included a video of a lecture with synchronized slides, or no video, which included the slides but only an audio narration of the lecture. Learning, cognitive load and social presence were assessed, but a significant difference was found only for cognitive load, with video experiencing greater cognitive load, t (24) = 2.45, p < .05. In Study 2, students (N = 25) were randomly assigned to either video or no video condition. Background knowledge and visual/verbal learning preference were assessed before viewing the presentation, and learning, cognitive load, and social presence were assessed after viewing. No significant differences were found for learning or social presence. However, a significant visual/verbal learning preference by condition interaction was found for cognitive load, F (1,21) = 4.51, p < .05: low visual-preference students experienced greater cognitive load in the video condition, while high visual-preference students experienced greater cognitive load in the no video condition.  相似文献

This study investigates the benefits of simulated social interaction (social presence) through virtual agents for older users’ experience in retail Web sites, particularly with respect to age-related barriers to the adoption of online retailing. In Study 1, through four focus group interviews, we identified six social–psychological barriers to the adoption of online shopping among older users (mean age of 73 years). These included barriers relating to perceived risks, trust, social support, familiarity, experience, and search. In Study 2, a laboratory experiment with older users (mean age of 69 years) demonstrated that embedding a virtual agent that serves search and navigational/procedural support functions in the online store leads to increased perceived social support, trust, and patronage intention for the online store. Mediational analyses further revealed that the effect of virtual agents: (1) on trust is mediated by perceived social support; and (2) on patronage intentions is mediated in part by trust and perceived risks. The study provides important implications on the design of virtual agents for older users of e-commerce applications, and on building online trust and e-service patronage through virtual agents.  相似文献

Introduction

Subjective workload measures are usually administered in a visual-manual format, either electronically or by paper and pencil. However, vocal responses to spoken queries may sometimes be preferable, for example when experimental manipulations require continuous manual responding or when participants have certain sensory/motor impairments. In the present study, we evaluated the acceptability of the hands-free administration of two subjective workload questionnaires - the NASA Task Load Index (NASA-TLX) and the Multiple Resources Questionnaire (MRQ) - in a surgical training environment where manual responding is often constrained.

Method

Sixty-four undergraduates performed fifteen 90-s trials of laparoscopic training tasks (five replications of 3 tasks - cannulation, ring transfer, and rope manipulation). Half of the participants provided workload ratings using a traditional paper-and-pencil version of the NASA-TLX and MRQ; the remainder used a vocal (hands-free) version of the questionnaires. A follow-up experiment extended the evaluation of the hands-free version to actual medical students in a Minimally Invasive Surgery (MIS) training facility.

Results

The NASA-TLX was scored in 2 ways - (1) the traditional procedure using participant-specific weights to combine its 6 subscales, and (2) a simplified procedure - the NASA Raw Task Load Index (NASA-RTLX) - using the unweighted mean of the subscale scores. Comparison of the scores obtained from the hands-free and written administration conditions yielded coefficients of equivalence of r = 0.85 (NASA-TLX) and r = 0.81 (NASA-RTLX). Equivalence estimates for the individual subscales ranged from r = 0.78 (“mental demand”) to r = 0.31 (“effort”). Both administration formats and scoring methods were equally sensitive to task and repetition effects. For the MRQ, the coefficient of equivalence for the hands-free and written versions was r = 0.96 when tested on undergraduates. However, the sensitivity of the hands-free MRQ to task demands (ηpartial2 = 0.138) was substantially less than that for the written version (ηpartial2 = 0.252). This potential shortcoming of the hands-free MRQ did not seem to generalize to medical students who showed robust task effects when using the hands-free MRQ (ηpartial2 = 0.396). A detailed analysis of the MRQ subscales also revealed differences that may be attributable to a “spillover” effect in which participants’ judgments about the demands of completing the questionnaires contaminated their judgments about the primary surgical training tasks.

Conclusion

Vocal versions of the NASA-TLX are acceptable alternatives to standard written formats when researchers wish to obtain global workload estimates. However, care should be used when interpreting the individual subscales if the object is to make comparisons between studies or conditions that use different administration modalities. For the MRQ, the vocal version was less sensitive to experimental manipulations than its written counterpart; however, when medical students rather than undergraduates used the vocal version, the instrument’s sensitivity increased well beyond that obtained with any other combination of administration modality and instrument in this study. Thus, the vocal version of the MRQ may be an acceptable workload assessment technique for selected populations, and it may even be a suitable substitute for the NASA-TLX.  相似文献
