Asynchronous online discussion thread development: examining growth patterns and peer-facilitation techniques

This study extends the research on asynchronous online discussion (AOD) by providing a perspective on: (1) the growth patterns of discussion threads and (2) the influence of peer- or student-facilitation techniques on thread development. Using the Pointing, Questioning, Resolving and Summarizing (PQRS) facilitation techniques framework, the threaded discussions of seven AOD forums were carefully mapped out and each message in the postings was examined to determine the type of facilitation techniques applied. Results suggest that an online discussion thread grows either one of three patterns: a 'short thread pattern', an 'extended thread pattern' with an elongated structure or a 'split thread pattern' with a broad structure. Results also suggest that the use of Resolving and Summarizing facilitation techniques tends to foster early thread termination. Understanding how each PQRS student-facilitation technique impacts thread development reinforces the need to combine the use of 'questioning' techniques with other facilitation techniques to enhance thread continuity. We end by discussing some possible implications and issues for future research.     

When to jump in: The role of the instructor in online discussion forums

As asynchronous discussion forums become more prevalent in online and flexible-delivery modes of teaching, understanding the role that instructors play in student learning in these forums becomes an important issue. Whether the instructor chooses to lead discussions or to keep a low profile can affect student participation in surprising ways. In this study, we investigate how instructor participation rates, the timing of instructor postings (during or at the end of a forum) and nature of their postings (questions, answers or a mix of the two) relate to student participation and perception.     

When groups decide to use asynchronous online discussions: collaborative learning and social presence under a voluntary participation structure

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.     

Promoting and scaffolding argumentation through reflective asynchronous discussions

The purpose of this quasi-experimental study was to explore the impact of asynchronous discussion on the quality and complexity of college students’ arguments. Three different cohorts of students registered in a physical science course in 2009 Fall, 2010 Spring, and 2010 Fall semesters were briefly supported with scaffolding in class and then involved in argumentation about socio-scientific issues as take-home assignments. Each cohort was divided into an asynchronous online communication group and a paper–pencil group. The findings showed that very few students’ arguments from either group were rated low in quality levels of 1 or 2 on a five-scale level. Additional comparisons revealed that the asynchronous online communication group students slightly outperformed their counterparts in terms of mean quality level of arguments (effect sizes ranged from 0.25 to 0.35) and the frequency of rebuttals. The major finding is that after only one hour of scaffolding followed by the opportunity to practice argumentation at home, students’ argumentation skills were slightly better developed through reflective asynchronous online discussions about socio-scientific issues than through paper-pencil practice.     

The effect of moderator’s facilitative strategies on online synchronous discussions

Moderators play an important role within a computer supported collaborative learning environment, and thus facilitative strategies and communication technology are nowadays used to enhance students’ learning. This study proposed facilitative strategies as a guide for students’ learning, and explored the influence of these strategies on the students’ online synchronous discussion. A total of 331 senior high school students from eight computer classes in northern Taiwan were recruited to participate in this study. They were randomly assigned into an experimental condition, with the moderators’ facilitation to complete online learning tasks, and the control condition without moderators’ support. To fulfill the goal of the research, four strategies—helping students focus on the main topic, facilitating students’ making argumentation, giving students positive feedback, and helping students sustain threaded discussion—were adopted to facilitate the online synchronous discussion in the experimental condition. According to the results of the content analysis, four group discussion patterns were revealed, including collaboration, centralization, partial contribution, and non-interaction. The findings suggest that the moderator helped enhance the collaboration pattern and increase the online participation rate. In addition, it was found that the strategies of helping students focus on the main topic and giving students positive feedback were frequently employed.     

It is about timing: Network prestige in asynchronous online discussions

Asynchronous online discussions are broadly used to support social learning. This paper reports on an undergraduate class's online discussion activities over one semester. Applying social network analysis, this study revealed a participation gap among students reflected by their varied levels of network prestige. The low‐prestige group initiated equivalent volumes of interactions but were less reciprocated. In‐depth analysis found the high‐prestige group also advantageous in other network measures such as closeness centrality and eigenvector centrality, as well as the strength, persistence, and reciprocity of their ties. To probe potential explanations of the revealed gap, we further contrasted post content and posting behaviours between two groups. Results did not identify any significant differences in post content but found low‐prestige students' participation less timely and more temporally compressed. This paper calls for attention to the participation gap in online discussions, microlevel temporal patterns of student activities, and practical means to scaffold student participation in asynchronous online discussions.     

Towards identifying unresolved discussions in student online forums

Online discussion is a popular form of web-based computer-mediated communication and is a dominant medium for cyber communities in areas of information sharing, customer support and distributed education. Automatic tools for analyzing online discussions are highly desirable for better information management and assistance. For example, a summary of student Q&A discussions or unresolved questions can help the instructor assess student dialogue efficiently, which can lead to better instructor guidance for student learning by discussion. This paper presents an approach for classifying student discussions according to a set of discourse structures, and identifying discussions with confusion or unanswered questions. Inspired by the existing spoken dialogue analysis approaches, we first define a set of forum “speech acts” (F-SAs) that represent roles that individual messages play in threaded Q&A discussions, such as questions, raising issues, and answers. We then model discourse structures in discussion threads using the F-SAs, such as whether a question was replied to with an answer. Finally, we use such discourse structures in classifying and identifying discussions with unanswered questions or unresolved issues. We performed an analysis of the discussion thread classifiers and the system showed accuracies from 0.79 to 0.87 on several discussion classification problems. This analysis of human conversation via online discussions provides a basis for development of future information extraction and intelligent assistance techniques for online discussions.     

Examining students’ online interaction in a live video streaming environment using data mining and text mining

This study analyses the online questions and chat messages automatically recorded by a live video streaming (LVS) system using data mining and text mining techniques. We apply data mining and text mining techniques to analyze two different datasets and then conducted an in-depth correlation analysis for two educational courses with the most online questions and chat messages respectively. The study found the discrepancies as well as similarities in the students’ patterns and themes of participation between online questions (student–instructor interaction) and online chat messages (student–students interaction or peer interaction). The results also identify disciplinary differences in students’ online participation. A correlation is found between the number of online questions students asked and students’ final grades. The data suggests that a combination of using data mining and text mining techniques for a large amount of online learning data can yield considerable insights and reveal valuable patterns in students’ learning behaviors. Limitations with data and text mining were also revealed and discussed in the paper.     

Encouraging equitable online participation through curriculum articulation

Student participation is a central issue in debates around online education. In most instances, course convenors wish to increase the amount of participation, while ensuring that the quality is of an acceptable standard. They also wish to ensure that their students have adequate access to the technology, and that there is no undue dominance by any groups of students. In order to achieve the desired degree and balance of participation, various strategies are pursued—most of these focus on the awarding or denial of marks. In this exercise, first year Health Sciences students were introduced to online discussions as part of an Information Technology/Information Literacy (IT/IL) stream in their curriculum. Most importantly, the nature of the participation was to be guided purely by the philosophy and content of the main Health Sciences curriculum, with no overt reward or punishment system for participation in the online discussions. An analysis of the number of postings and the spread of postings shows an acceptable level of equitable participation across the student body. The main conclusion is that effective participation in online discussions is possible by curriculum articulation.     

“Always a shadow of hope”: Heteronormative binaries in an online discussion of sexuality and sexual orientation

In this article, I examine an asynchronous online discussion about sexuality that lasted for several weeks and involved students at three different universities, seven of whom I interviewed. Although issues of gay rights and alliance groups were brought up, students focused primarily on the causes of homosexuality and whether homosexuality is natural or not, with one student insistently posting that homosexuality is unnatural because same-sex couples cannot experience “true love-making.” On one level the focus on the causes and naturalness of homosexuality (with few references to heterosexuality) reinforced the heteronormative binaries that often structure thinking and discussions about sexuality, a reinforcement that I initially found disheartening. However, in many ways I came to realize that this online thread still served important academic and personal purposes for students despite and because of being situated in binaries. Drawing from my reading of the posts and from discourse-based interviews with participants, I show that online discussions developed around heteronormative binaries can serve as catalysts for movement in students’ thinking about complex issues and that online spaces in particular are valuable forums for students to articulate and then complicate their understandings of issues relating to sexuality and sexual orientation.     

Students' views of collaboration and online participation in Knowledge Forum

This study examined students’ views of collaboration and learning, and investigated how these predict students’ online participation in a computer-supported learning environment. The participants were 521 secondary school students in Hong Kong, who took part in online collaborative inquiry conducted using Knowledge Forum™. We developed a questionnaire to assess the students’ views of their collaboration aligned with the knowledge-building perspective. We also administered the Learning Process Questionnaire to examine their preferred approaches to learning. The students’ online participation in Knowledge Forum was examined using the Analytic Toolkit software. Analyses indicated that students who viewed their collaboration as more aligned with collaborative knowledge building were more likely to employ a deep approach to learning. A structural equation model indicated that the students’ views of collaboration exerted a direct effect on online participation in Knowledge Forum and mediated the effects of deep approaches on forum participation. Implications of examining students’ views of collaboration for productive online participation are discussed.     

The POD model: Using communities of practice theory to conceptualise student teachers’ professional learning online

This paper focuses on the broad outcomes of a research project which aimed to analyse and model student teachers’ learning in the online components of an initial teacher education course. It begins with discussion of the methodological approach adopted for the case study, which combined conventional data gathering techniques with those which are facilitated using the ‘panoptical’ tools of the VLE. The author has synthesized case study evidence, learning theory (Community of practice theory) and the advice of a key theoretician, to produce an original model of student teachers’ learning online within a professional online district (POD). The most distinctive feature of the POD model is the learning-curriculum dichotomy which recognises the potential of a VLE as a venue in which student teachers, working together in a community of practice, construct their own curriculum (both formal and informal/’hidden’. The paper also examines the key technological and pedagogical issues which affect students’ online learning.     

Students’ linguistic behaviour in online discussion groups: Does gender matter?

This research examined students’ language use and interaction styles in text-based, computer-mediated discussion groups. The contributions of 197 introductory psychology students (149 females, 48 males) participating in asynchronous computer-mediated communication (CMC) were collated. Both quantitative and qualitative methods were used, under the methodological framework of qualitative content analysis [Mayring, P. (2000). Qualitative Content Analysis. Forum Qualitative Sozialforschung/Forum: Qualitative Social Research [online] 1. http://qualitative-research.net/fqs-e/2-00halt-e.htm Accessed 10.06.2001]. A coding system, which incorporated the creation of ‘supercodes’, was developed using Atlas.ti 4.2 and used to code 699 student postings in total. The frequencies of coded categories were analysed using χ² statistics in SPSS 10. It was found that males and females were similar regarding use of individual linguistic variables, with the exception of intensifiers as more females used them than males. However, significant gender differences were found in use of many of the stylistic variables and the supercode analysis showed overall gender-related patterns in interaction styles. Males were more likely to use authoritative language and to respond negatively in interactions, than females. On the other hand, females were more likely to explicitly agree and support others and make more personal and emotional contributions, than males. The results suggest that gendered power differentials may carry over into online contexts, which has implications for the use of CMC in education.     

Comparing the social knowledge construction behavioral patterns of problem-based online asynchronous discussion in e/m-learning environments

In recent years, researchers have conducted various studies on applying wireless networking technology and mobile devices in education settings. However, research on behavioral patterns in learners' online asynchronous discussions with mobile devices is limited. The purposes of this study are to develop a mobile learning system, mobile interactive teaching feedback system (MITFS), linked to both mobile devices and the internet, to support learners with online asynchronous discussion, and combine content analysis and sequential analysis to compare and contrast the social knowledge construction behavioral patterns of problem-based asynchronous discussion in e-learning and m-learning environments. This study investigated four weeks of online discussions in an “Introduction to Computer Science” course involving forty first year university students. The control group (online asynchronous discussion without mobile devices) and the experimental group (online asynchronous discussion with mobile devices) in the group discussions were explored. By using content analysis and sequential analysis for the problem-based online asynchronous discussion of the behavioral patterns and differences between students in control and experimental group, the results showed that using mobile devices in online asynchronous discussion influenced students' learning performance. Some interesting results were found. Firstly, when the students used mobile devices in discussion situations, they could more engage in reflecting thinking, sharing more information, and further facilitating social knowledge construction among group members. Secondly, the experimental group performed better than the control group in terms of participation and diversity in knowledge construction behavioral patterns. Finally, based upon the findings, some implications are proposed for further research.     

A study of the relationships among learning styles, participation types, and performance in programming language learning supported by online forums

This study is focused on the relationships among learning styles, participation types, and learning performance for programming language learning supported by an online forum. Kolb’s learning style inventory was used in this study to determine a learner’s learning type: ‘Diverger’, ‘Assimilator’, ‘Converger’, and ‘Accommodator’. Social Learning Theory was also used to define four participation types. These types in turn were used to describe the learning associated with the use of online forums: ‘Replier’, ‘Asker’, ‘Watcher’, and ‘No activity’.A total of 144 students participated in this experiment as part of a half semester ASP.NET programming language learning courses. The course contained an online forum for supporting the students’ social activities and participation. In this study, ‘learning score’ and ‘satisfaction’ were used to measure learning performance.The results of this study were the following: (1) different learning styles were associated with significantly different learning scores and that the ‘Accommodator’ style was associated with superior learning scores; (2) participation types were also associated with significantly different learning scores and that the ‘Replier’ type is associated with superior learning scores; (3) learning satisfaction is not significantly different among the different learning styles or different participation types, but the average is significantly higher than average values (3.5) of 7-point Likert scale; (4) there is no significant association between learning styles and participation types. Explanations and discussions of these results are offered.Based on the results of this study, we propose that programming language learning, supported with online forums and students’ active participation, increases learning performance as measured by student learning scores.     

Online collaboration: Collaborative behavior patterns and factors affecting globally distributed team performance

Studying the collaborative behavior of online learning teams and how this behavior is related to communication mode and task type is a complex process. Research about small group learning suggests that a higher percentage of social interactions occur in synchronous rather than asynchronous mode, and that students spend more time in task-oriented interaction in asynchronous discussions than in synchronous mode. This study analyzed the collaborative interaction patterns of global software development learning teams composed of students from Turkey, US, and Panama. Data collected from students’ chat histories and forum discussions from three global software development projects were collected and compared. Both qualitative and quantitative analysis methods were used to determine the differences between a group’s communication patterns in asynchronous versus synchronous communication mode. K-means clustering with the Ward method was used to investigate the patterns of behaviors in distributed teams. The results show that communication patterns are related to communication mode, the nature of the task, and the experience level of the leader. The paper also includes recommendations for building effective online collaborative teams and describes future research possibilities.     

A blended learning Approach to teaching foreign policy: Student experiences of learning through face-to-face and online discussion and their relationship to academic performance

This article presents research on students’ experiences of learning through a blend of face-to-face and online discussion. The participants in our study were students enrolled in a foreign policy course at a major Australian university. Students’ conceptions of learning through discussion, and their approaches to both face-to-face and online discussion, were elicited through open-ended questionnaires and semi-structured interviews. Students’ responses to both open-ended questionnaires and interviews were analysed using a phenomenographic framework. Qualitative variations in students’ conceptions and approaches were categorised and were found to form a hierarchy. Subsequent quantitative analysis found associations between students’ conceptions of learning through discussion, their approaches to both face-to-face and online discussion and their academic performance (as indicated by the final mark for the course). Implications for teaching and further research are discussed.     

Students’ participation intention in an online discussion forum: Why is computer-mediated interaction attractive?

Anecdotal evidence indicates that an online discussion forum may not be utilized to its full potential in enhancing the effectiveness and efficiency of teaching due to a lower than expected student participation rate. This paper seeks to identify the motivational behavioral factors influencing students’ intention to participate in an online discussion forums (ODF). Drawing on the literature on social psychology and applying the theory of reasoned action, we develop a conceptual model of intention to participate in an online discussion forum and empirically test the hypotheses in a cross-sectional quantitative survey. The findings indicate that expectancy on hedonic outcome and utilitarian outcome and peer pressure positively influence the participation intention of students. Also, the perceived importance of learning positively moderates the relationship between utilitarian outcome expectancy and participation intention. Theoretical and practical implications of the findings are discussed.
