We explored the scientific argumentation that occurs among university biology students during an argumentation task implemented in two environments: face-to-face in a classroom and online in an asynchronous discussion. We observed 10 student groups, each composed of three students. Our analysis focused on how students respond to their peers’ unscientific arguments, which we define as assertions, hypotheses, propositions, or explanations that are inaccurate or incomplete from a scientific perspective. Unscientific arguments provide opportunities for productive dissent, scientific argumentation, and conceptual development of scientifically desirable conceptions. We found that students did not respond to the majority of unscientific arguments in both environments. Challenges to unscientific arguments were expressed as a question or through explanation, although the latter was more common online than face-to-face. Students demonstrated significantly more epistemic distancing in the face-to-face environment than the online environment. We discuss the differences in discourse observed in both environments and teaching implications. We also provide direction for future research seeking to address the challenges of engaging students in productive scientific argumentation in both face-to-face and online environments. 相似文献

Two mechanisms for engaging in critical reflective dialogue are discussed and compared: face-to-face meetings and asynchronous online discussion. The context is an umbrella action research project, with over 20 participants, which aimed to improve practices in online teaching and contribute to the development of graduate attributes. The article compares discussion using the two modes (face-to-face and online) of the nature of and development of problem-solving and other graduate attributes. Face-to-face discussion was wide ranging and quite loosely structured, so divergent aspects of a topic were uncovered. The asynchronous nature of online discussion, however, permitted topics to be explored more thoroughly. The two modes worked well in conjunction with one another, if aspects of face-to-face discussion topics were posted online as discussion threads. The asynchronous online discussions then allowed each thread to be explored in depth, so that collective understanding of a given topic could be enhanced. 相似文献

Online education is often assumed to be synonymous with asynchronous instruction, existing apart from or supplementary to face-to-face instruction in traditional bricks-and-mortar classrooms. However, expanding access to computer- mediated communication technologies now make new models possible, including distance learners synchronous online attendance of face-to-face courses. Going beyond traditional uses of videoconferencing (e.g., real-time remote viewing with limited student interaction), this article describes the use of freely available technologies to support synchronous cooperative learning activities involving both face-to-face and hybrid doctoral students. Specifically, we describe the rationale behind pedagogical choices and specify how various technologies were re-purposed to create a virtual classroom space in which all possible combinations of face-to-face and hybrid students worked together in multiple small-groups across single class sessions. Implications for course development, the implementation of cooperative learning activities in online settings, and the use of both synchronous and asynchronous methods of online instruction are discussed. 相似文献

In this study the investigator compared two sections of the same course-one section was online and asynchronous; the other was face-to-face-by examining gender, age, learning preferences and styles, media familiarity, effectiveness of tasks, course effectiveness, test grades, and final grades. The two sections were taught by the same instructor and used the same instructional materials. The results revealed no significant differences in test scores, assignments, participation grades, and final grades, although the online group's averages were slightly higher. Ninety-six percent of the online students found the course to be either as effective or more effective to their learning than their typical face-to-face course. There were no significant differences between learning preferences and styles and grades in either group. The study showed that equivalent learning activities can be equally effective for online and face-to-face learners. 相似文献

This review focuses on three interconnected socio-emotional aspects of online learning: interaction, sense of community and identity formation. In the intangible social space of the virtual classroom, students come together to learn through dialogic, often asynchronous, exchanges. This creates distinctive learning environments where learning goals, interpersonal relationships and emotions are no less important because of their ‘virtualness’, and for which traditional face-to-face pedagogies are not neatly transferrable. The literature reveals consistent connections between interaction and sense of community. Yet identity, which plausibly and naturally emerges from any social interaction, is much less explored in online learning. While it is widely acknowledged that interaction increases the potential for knowledge-building, the literature indicates that this will be enhanced when opportunities encouraging students’ emergent identities are embedded into the curriculum. To encourage informed teaching strategies this review seeks to raise awareness and stimulate further exploration into a currently under-researched facet of online learning. 相似文献

Project-based learning engages students in problem solving through artefact design. However, previous studies of online project-based learning have focused primarily on the dynamics of online collaboration; students' knowledge construction throughout this process has not been examined thoroughly. This case study analyzed the relationship between students' levels of knowledge construction during asynchronous online discussions with respect to engagement in project-based learning. Graduate students' online postings in a course that comprised both project-based and non-project learning activities were coded and counted for knowledge construction, teaching, and social interaction moves using computer-mediated discourse analysis. Chi-square analyses found that the instructor's teaching discourse remained fairly consistent during project-based and non-project learning. Despite this, students' online discussions during project-based learning were characterized by more advanced levels of knowledge construction, where ideas were rationalized and integrated into plausible solutions. In contrast, students' online postings outside project-based learning rarely moved beyond the lower levels of information sharing and idea exploration. Based on these results, guidelines for designing and facilitating online project-based learning are presented and discussed. 相似文献

Building interpersonal connections in asynchronous online learning is important, but it is harder to achieve compared to face-to-face learning experiences due to its mostly text-based nature. Facebook is a popular social media platform and has been used as an outside-class communication space in formal learning contexts to supplement cognitive and affective aspects of learning. In this study, we used Facebook groups as supplemental social spaces in two asynchronous online master’s-level courses to understand if it impacted students’ perceptions of social presence (i.e., copresence, immediacy, and intimacy), learning interaction with faculty and peers, as well as sociability of the online learning environment. The results indicated that students felt more positively about social presence and learning interactions with other classmates and their instructor and perceived the course as having more sociability after they joined the class Facebook group. Findings have implications for supporting social impression formation in online learning. 相似文献

Our universities are becoming increasingly diverse at the same time as online asynchronous discussions (OADs) are emerging as the most important forum for computer mediated communication (CMC) in distance education. But there is shortage of studies that explore how graduate students from different ethnic, linguistic and cultural backgrounds use OADs for academic discourse socialization. This article discusses a qualitative study conducted to address these issues. Language socialization and community of practice theories informed the study. Analyses of surveys, interviews, and Blackboard postings from seven hybrid courses reveal that participants perceived OADs highly positively and used them as a virtual community for academic and professional discourse socialization and appropriation. Findings also suggest that students experienced some frustrations and disappointments regarding professorial presence and grading. We discuss these findings, show how academic and professional discourse socialization occurs in asynchronous virtual reality, and draw implications for further research and practice. 相似文献

Students who fail algebra are significantly less likely to graduate on time, and algebra failure rates are consistently high in urban districts. Identifying effective credit recovery strategies is critical for getting students back on track. Online courses are now widely used for credit recovery, yet there is no rigorous evidence about the relative efficacy of online versus face-to-face credit recovery courses. To address this gap, this study randomly assigned 1,224 ninth graders who failed algebra in 17 Chicago public high schools to take an online or face-to-face algebra credit recovery course. Compared to students in face-to-face credit recovery, students in online credit recovery reported that the course was more difficult, were less likely to recover credit, and scored lower on an algebra posttest. There were no statistically significant differences by condition on any outcomes measured during the second year of high school (standardized mathematics test and algebra subtest scores, likelihood of passing subsequent math classes, cumulative math credits, or on-track rates). The benefits and challenges of online learning for credit recovery are discussed in light of the findings to date. 相似文献

Previous computer conferencing research has been concerned with the organizational, technical, social, and motivational factors that support and sustain online interaction. This article studies online interaction from a different perspective. Rather than analyze the processes that sustain discourse, the following research examines how and why discussions shut down. A computer simulation of asynchronous threaded interaction suggests that certain common online habits, when practiced by many people, can adversely affect the lifespan of some threads. Specifically, the widespread practice of focusing attention on unread notes during computer conferencing sessions can produce a starvation condition that hastens the death of some threads and reduces the likelihood that inactive threads will become active again. The longevity of a thread, therefore, is partially affected by the kinds of routines that online participants follow when they use a computer conferencing interface. The educational implications of this finding are discussed, and strategies are presented for limiting adverse educational effects. 相似文献

Currently available web page accessibility guidelines focus more on reading and writing, with inadequate attention to other aspects of online learning such as computer-mediated communication. This study aims to explore the engagement of Malaysia secondary school students with dyslexia and students without dyslexia on various synchronous and asynchronous communication interaction technologies in an online collaborative learning environment. Multiple case within subject qualitative study was employed to investigate the engagement of students using a semi structured interview guideline. The findings revealed that (1) text chat is unsuitable for learning discussion for all learners, (2) forum affords self-paced and organized formal discussion for most learners and (3) video conferencing is suitable for interactive face-to-face, verbal discussion for most learners. 相似文献

This study verified the efficacy of the intentional repetition technique in improving interaction in asynchronous online discussions by taking into account the learning styles of the participants. A conceptual framework served for the development of the technique, which conceptualises efficient and cohesive interaction on a continuum of process that move from social presence to production of an artefact. Sixty-one university students participated in the study. A quasi-experimental research design was used. The subjects, who were assigned randomly into two groups, were tested using Kolb's learning style inventory. The results showed that the experimental group exposed to the intentional repetition technique produced significantly better interaction than the control group, regardless of their learning styles, which had no significant effect on the interaction. Moreover, there was no interaction effect between the learning styles and the treatment. The implications arising from these results identify various suggestions for increasing the coherence and depth of the interaction amongst students in asynchronous online discussions. 相似文献

This article reports on a six-month telementoring initiative in a Canadian community nursing organization. The way in which Internet technologies may support and augment face-to-face mentorship of health care professionals is a relatively unexplored area of research and was the focus of this project. Participants ( N =22) were all employees of Saint Elizabeth Health Care (SEHC), a community nursing agency servicing 150,000 clients in urban and rural Ontario, Canada. Nurse mentees ( n =11) and nurse-mentors ( n =11) engaged in collaborative discourse in webKnowledge Forum, a second-generation computer-supported intentional learning environment (CSILE). Discussions among all participants were directed at collaborative learning and professional development. Results indicate that mentees contributed and read more notes than mentors and were more likely to engage in threaded discourse with peers. Readership patterns were similar for both groups. Fifty-eight per cent of all nurses reported improved asynchronous communication and problem-solving skills as a result of online collaboration. Seventy-five per cent of all respondents reported a positive professional development experience and 50% of all respondents reported improved clinical practice ability as outcomes of the telementorship program. All reported high satisfaction with the technology. It is concluded that this project facilitated a shift from dyadic mentor-mentee (preceptor-intern) training to communal opportunistic learning and professional development. 相似文献

This study investigated 6 weeks of online asynchronous discussions in a graduate-level course involving eleven students. The
research purposes of this study were to identify patterns of collaborative knowledge exploration (CKE) and to suggest new
analytical dimensions for investigating online discussions. Based upon a unique theoretical framework integrating the concepts
of transition community and discourse community, three major dimensions of online asynchronous learning were adopted in the
analysis. The first dimension focuses on the various forms of social negotiation in the discourse. The second dimension regards
references to various learning resources, while the third is related to the coherence of the resources utilized. Based upon
these dimensions and the analysis of the participating students’ online asynchronous discussions, this study suggested ten
different patterns of CKE representing the cognitive processes of Elaborating, Challenging, Correcting, and Debating. We argue
that the proposed analytical framework allows us to interpret the sociocultural and cognitive aspects of students’ interactions
for online problem-based learning. In addition, the results suggest that the more cognitively demanding the pattern is, the
less frequently it occurs. Potential factors contributing to the observed findings are discussed in this study. 相似文献
