This research investigated how differently elementary school students participate in synchronous online collaborative learning by analysing their discussions with their partners. Two hundred and seventy-eight Taiwanese students, ranging in age from 11 to 12 years old, were involved in this study. The students were randomly arranged within-class into three-member groups. Each group used a collaborative learning system to discuss and accomplish a group assignment (creating a shared concept map). The textual discussions by each individual student were collected, categorised and accumulated. Cluster analysis was adopted to statistically classify students based on their discussion characteristics. We found that a student, while participating in online collaboration and communication, exhibited a distinct style: less contributing, coordination emphasising, communicative or task-oriented. In addition, students exhibiting the task-oriented pattern and students predominantly showing communicative behaviours were found to have better learning performance and retain more knowledge than students observed to be coordination emphasising or less contributing within group collaboration.  相似文献

Computer-mediated communication (CMC) has been adopted in most e-learning settings. However, few research studies have considered the effect of different CMC. This study examined how and why synchronous communication affected participation in online discussions. Two online classes that participated in two asynchronous and two synchronous online discussions were examined. Actual and perceived measures of participation indicated that synchronous communication induced personal participation, which could be regarded as a complement to cognitive participation. Personal participation involves more intense interaction better supported by synchronous communication while cognitive participation is a more reflective type of participation supported by asynchronous communication. In synchronous discussions, the e-learners felt that they worked together and were not restricted to only discuss course content. This was likely to induce arousal and motivation and increased convergence on meaning, especially in small groups.  相似文献

Expertise recognition is challenging in teamwork, particularly in intercultural collaboration. This research seeks to investigate how cultural differences in communication styles may affect expertise recognition and influence in face-to-face (FtF) versus text-based computer-mediated communication (CMC). Using experimental intercultural groups, we found that in FtF groups East Asian experts had a lower participation rate, and were perceived as less competent, less confident, and less influential than experts from Western culture. No such differences occurred in CMC. The results support mediated moderation effect of perceived confidence on expert influence such that changes in perceptions of Chinese and American experts' confidence accounted for their different levels of influence in CMC versus FtF. No such effect was found with participation rate.  相似文献

A three-part conception of group identity is proposed that draws on common fate, cohesiveness, and cognitive views of group identity. The changing contribution of these three components to group identity was examined for 31 original and 29 reconfigured groups which met for 7 consecutive weeks using either face-to-face (FIF) or computer-mediated communication (CMC). Group identity was consistently lower for computer-mediated groups, and this effect was stronger in the reconfigured groups. In the original groups, group identity started high and declined for both FTF and CMC groups. In the reconfigured groups, developmental patterns differed from those of the original groups, and also differed by communication medium. Individual differences accounted for a substantial amount of variance in group identity across original and reconfigured groups.  相似文献

This study aims to extend the literature on mobile communication by demonstrating that multifaceted mobile practices work in coordination with one another to predict enhanced engagement in public life. Using a national survey of adults in South Korea, we show that informational mobile phone use to gather and discuss content about news and public affairs is positively associated with political participation while the corresponding link for relational mobile phone use to enhance strong personal tie relationships being also significant. More importantly, the findings indicate that the two mobile usage patterns interact with each other to explain increased involvement in political activities. However, analysis of the three-way interaction points to a noteworthy caveat, namely that those who are already engaged, by virtue of their perceived capacity to produce desired outcomes in politics (i.e., self-efficacy), are even more likely to obtain motivational benefits from the manifold uses of mobile telephony.  相似文献

The present study examines the role of affect, or emotion, in the performance of computer-mediated and face-to-face work groups. Past research has focussed on the role of affect in either individual information processing or behavior in settings requiring interpersonal interaction. Little research has examined the role of affect in groups, especially those in a work group setting. Even less is known about the role that the communication medium plays in the expression or impact of group members' affect. To integrate these domains, a general model of affect in work group settings is proposed. Predictions are derived from the relevant affect, group interaction, and group performance literatures. In addition, predictions about the moderating role of the communication system are discussed. Results from a path analysis suggest that affect has a substantial impact intragroup on processes as well as on work group performance. In face-to-face groups, the affect experienced by group members had an impact on the group's cohesiveness, the amount members participated in the task, and the degree to which members processed information relevant to the task. These factors, in turn, had implications for the group's performance. In computer-mediated groups, affect had an effect on the group's cohesiveness and the amount of information processing, though these were unrelated to any performance measures for these groups. Similarities and differences between communication media are discussed in terms of their importance for extending our understanding about the role of affect in a group performance context.  相似文献

This study aimed to clarify the relationship between media, learners’ perception of social presence, and output in communicative learning using synchronous computer-mediated communication (SCMC). In this study, we developed four types of SCMC: videoconferencing (image and voice), audioconferencing (voice but no image), text chat with image (image but no voice), and plain text chat (no image and no voice). Each system allows learners to be conscious of and utter a target formulaic expression. I investigated the effect of each system on psychological perception and productive output as well as the relationship between perception and output. The results show that image and voice promote consciousness of natural communication and relief, while a text-mediated system enhances confidence in grammatical accuracy. In order to clarify the relationship between media, affective side, and output, path analysis was conducted using SPSS Amos 7.0. The results indicated that voice communication strongly affects both learners’ affective side and output. The existence of a partner’s image enhances the consciousness of natural communication, which leads to a number of self-corrections, an aspect of learning performance. However, voice communication has a negative effect on confidence in grammatical accuracy.  相似文献

The purpose of this study is to explore how groups decide to use asynchronous online discussion forums in a non-mandatory setting, and, after the group decision is made, how group members use online discussion forums to complete a collaborative learning project requiring complex data gathering and research processes. While a large body of research on computer-mediated communication (CMC) has documented successful intervention strategies to promote and sustain online discussion forums, little of the research has examined the use of online discussion forums in voluntarily contexts, wherein the decision to use online discussion forums is a personal decision and participation is not a graded component. This study approaches the research questions using a naturalistic case study of one graduate-level blended learning course with 55 students. Employing both student interviews and content analysis methods, this study revealed that the factors affecting the group decision to use online discussion forums are (1) successful or unsuccessful experiences during the first trial, (2) perceived affordances of CMC tools, and (3) the interplay between the nature of collaborative tasks and perceived efficiency. The content analysis of online postings in two voluntary groups revealed that when groups decided to use online discussion forums, participation levels were almost equal among individual group members, and discussion threads were sustained until the final completion of the collaborative project.  相似文献

Abstract   A question associated with the introduction of computer-supported collaborative learning (CSCL) is whether all participants profit equally from working in CSCL environments. This article reports on a review study into gender-related differences in participation in CSCL. As many of the processes in CSCL are similar to those in computer-mediated communication (CMC), studies into CMC are also included in the review. Male dominance is found to play a role in many CMC settings. A learning culture with an explicit focus on participation by all students seems to be related to a more gender-balanced participation in CMC, however. A tendency for boys to be more active participants than girls is also present in CSCL environments, but it is less pronounced than in CMC. This may be explained by the fact that participation is explicitly promoted in most CSCL environments. Gender differences in the character of students' contributions are found in both CMC and CSCL. It is concluded that in order to avoid gender-stereotyped participation and communication patterns, it is necessary to explicitly address inclusiveness as an aspect of a collaborative classroom culture. A plea is made for further research into differential participation by students in CSCL, and the effects thereof on cognitive and affective learning outcomes. Research should also focus on the question how classroom cultures can be promoted that support active participation of all students aimed at collaborative knowledge construction.  相似文献

This study examines how group experience, communication medium, and strategies for combining individual ideas influence the integrative complexity of group products. Each week for six weeks, members of 31 work groups wrote individual essays about their group tasks and experiences, and then collaborated on a group essay on the same topic. Results indicate that in the later weeks of the study, computer-mediated groups produce essays with higher integrative complexity than those of face-to-face groups. The integrative complexity of essays in later weeks is a joint function of the complexity of member ideas and the number of members who participate directly in writing the essay (scribes). The greater complexity of computer-mediated groups' essays in the later weeks of the study is partly accounted for by their use of more scribes and their inclusion of more unique member ideas.  相似文献

This article examines how technology and structural guidance influence the development of workgroups using computer-mediated communication (CMC). The results of two experiments support the notion that CMC workgroups develop over time in a similar manner to face-to-face groups. Technology availability had minimal, fleeting effects on group development. Structural guidance had a more pronounced effect, increasing feelings of belonging and goal commitment in newly formed groups, but lowering feelings of trust in maturing groups.  相似文献

The recent creation of global-area computer networks invites the development of tools and resources that can reap the scholarly advantages of such technology. In this paper, we discuss prospects for the productive use of computer-mediated communication (CMC) for scholarly interaction. We begin by describing the technology used to deliver information over academic networks and the kinds of disciplinary services that the technology enables. In the second half of the paper we consider factors that bear upon the development of CMC-based disciplinary centers and we call attention to their potential to create a highly interactive form of scholarship.Teresa Harrison and Timothy Stephen are Associate Professors of Communication. Teresa Harrison's research focusses on communication theory and organizational communication. Timothy Stephen specializes in interpersonal communication and the development of community.This research was funded, in part, by the Paul Beer Trust, administered by the School of Humanities and Social Sciences, Rensselaer Polytechnic Institute.  相似文献

Social media may be particularly adept at promoting niche products because of the tendency of consumers to participate in generating reviews and discussing such products, thereby raising interest in them. In this study, we investigate how patterns of user interaction in discussing a niche cultural product may influence participation levels, which in turn enhance consumption intentions. We show that higher levels of participation can indeed enhance consumption intention. Furthermore, interaction patterns with high inclusiveness and betweenness centralization may enhance participation levels, whereas out-degree centralization and core-periphery have a detrimental influence. Implications for research and practice are discussed.  相似文献

This study used Social Impact Theory to explore sources and functions of interpersonal influence in Computer-Mediated Communication. Participants were 43 female and 17 male graduate students ranging from 25 to 60 years of age. In each of five distinct graduate classes (n1 = 15, n2 = 11, n3 = 10, n4 = 12, n5 = 12) delivered online at a research university, participants engaged in anonymous and computer-mediated discourse and then nominated peers who were directive and/or influential (positive and negative) during the online interaction. High numbers of peer nominations were expected to characterize participants perceived as emanating social impact. Four interpersonal factors were chosen as strength operants in accordance with Social Impact Theory and were, therefore, expected to predict social impact. Of the four, assertiveness and exaggeration were significant, while emotional intensity and sensitivity were not. Two factors, contribution total and word total, were chosen as immediacy operants in accordance with Social Impact Theory. Both factors were found to be significant predictors of social impact. Implications of these findings relative to online learning and interpersonal influence as it occurs in an online context are discussed.  相似文献

Ambivalent effect of member portraits in virtual groups   总被引:2,自引:0,他引:2  
Abstract Knowledge exchange with shared databases can be seen as a public-goods dilemma. People are reluctant to contribute information because they save time, effort and perhaps social power if they withhold their knowledge and socially loaf. But if all people choose this individually efficient strategy, then no information exchange can take place, and the group is less effective than it would have been if all members contributed. Thus, in the knowledge-exchange situation, group norms and individual norms oppose each other. In order to strengthen people's orientation towards the group, virtual collaborative tools sometimes provide member portraits. But based on the Social Identity Model of Deindividuation Effect (SIDE)-Model, ambivalent effects of these member portraits are expected according to people's social categorization: when people identify more strongly with the group, such portraits enhance participation, whereas when people have a stronger individual identity, they undermine participation. This study links the concepts of social value orientation to identity salience. The assumption is that in the information-exchange dilemma, the social value orientation of a group member will determine whether group identity or individual identity becomes salient for that group member. We then extend the SIDE-model to the domain of social loafing and expect that portraits of the group members will have different effects for people with individual orientation and for people with prosocial orientation. An experiment confirmed this expectation and revealed a significant interaction between social value orientation and portraits. Especially striking is the result that for prosocials the provision of member portraits leads to an increase in social loafing. This is analogous to the predictions of the SIDE-model.  相似文献

This paper explores focus groups supported by group support systems (GSS) with anonymous interaction capability in two configurations: same time/same place and same time/different place. After reviewing the literature, we compare and contrast these anonymity-featured GSS-supported focus groups with traditional focus groups and discuss their benefits and limitations. We suggest directions for future research concerning GSS-supported focus groups with respect to technological implications (typing skills and connection speeds), national culture (high and low context; power distance), and lying behavior (adaptation of model of Hancock, J. T., Thom-Santelli, J., & Ritchie, T. (2004). Deception and design: The impact of communication technology on lying behavior. Proceedings of the 2004 conference on human factors in computing systems (pp. 129–134), whereby lying is a function of three design factors: synchronicity, recordability, and distributedness).  相似文献

In this study, we explore the cognitive style profiles and linguistic patterns of self-organizing groups within a web-based graduate education course to determine how cognitive preferences and individual behaviors influence the patterns of information exchange and the formation of communication hierarchies in an online classroom. Network analysis was performed on communication data collected from 1131 student messages posted in 19 asynchronous online discussion forums to determine centrality, clique membership, and core-periphery structure in the communication networks. The social network data were examined in relation to the students' cognitive style profiles, which were assessed using the Kirton Adaption-Innovation Inventory (KAI) (32 and 33). The cognitive style composition of small cliques (dyadic and triadic) was found to be highly heterogeneous, often with large cognitive gaps between clique members, which suggests that web-based environments may mask cognitive style differences that have been shown to create conflict in face-to-face interactions. In addition, the cognitive style mean of the students in the core of the network was found to be significantly more adaptive than that of the periphery group. To further characterize the nature of the communicative interactions, automated linguistic analysis was used to analyze the students' writing samples. Interestingly, students in the core of the social network demonstrated a significantly higher usage of several language features associated with individuals who actively promote enhanced group performance and cohesion. For our sample, the linguistic behaviors of students in the core of the social network, coupled with their more adaptive cognitive style preferences, suggest that these students may inherently place greater value on fostering group cohesion than those in the periphery.  相似文献

ABSTRACT

E-government on social media has received much attention lately. Despite a recent call for further research into social interaction and communication aspects of e-government on social media, there is still limited empirical evidence regarding why individuals participate in the social aspect of e-government services and how that relates to their expectations and satisfactions. The present work addresses this gap by extending the Expectation-Confirmation Theory (ECT) to study communication and social interactions in government Facebook groups. The results show that communication quality and responsiveness are two key elements that contribute to the perceived level of usefulness. These two variables together with social interaction had a statistically significant effect on the overall confirmation of expectations. Perceived usefulness and satisfaction predict continuance use intention of e-government social networking services with satisfaction influencing such intention more than perceived usefulness. Further multi-group analyses show that generational difference and usage frequency moderates the relationships of the extended model. Managerial implications are provided.  相似文献
