Attracting student participation in asynchronous online discussions: A case study of peer facilitation

Previous research studies on how to promote student participation in asynchronous online discussions have largely focused on the role of the instructor or tutor as facilitators. Not many investigated student facilitation. This article reports a qualitative study examining the facilitation techniques used by student facilitators to attract their course mates to participate in asynchronous online discussions. Data were collected from the students’ reflection logs and students’ online postings. To explore the extent to which student participation in an online discussion forum is successful, we looked at the depth of discussion threads. We deemed a student facilitator to have successfully attracted other students to participant if the discussion threads had a depth of six or more levels of students’ postings. We then examined in detail and reported the facilitation techniques that were exhibited by the student facilitators. Results showed that seven facilitation techniques were employed; the most frequently used were Socratic questioning and sharing personal opinions or experiences. We end by exploring potential implications for practice and for future research.     

Towards the refinement of forum and asynchronous online discussion in educational contexts worldwide: Trends and investigative approaches within a dominant research paradigm

The growth of asynchronous online discussion (AOD) in primary, secondary, undergraduate, and post-graduate contexts and courses has resulted in a growing body of literature that provides valuable insights into the issues surrounding the use of online writing, online discussion, and distance and blended learning in formal education worldwide. This phenomenological critical literature review provides an overview of research focused on forum use and AOD published from 2008 to 2012. Papers were chosen based on a selection process suggested by Wu et al. (2012), where nine of the most influential e-learning education and educational review journals were searched according to year, 2008–2012, and the following keywords: forum, threaded discussion, and threaded chat. Three teachers/educational researchers, each with at least five years of experience using forum and AOD in university contexts, further filtered the corpus through following a detailed inclusion/exclusion procedure, which resulted in a refined corpus of 43 journal papers. Quantitative analyses of results reveal most AOD research in educational contexts from 2008 to 2012 was carried out through or on Learning Management Systems (LMS) platforms in university settings, within computer and education classes, with blended learning dominating distance learning contexts. Most research settings were based in Asia and Europe, while the three countries with the most AOD publications were Singapore, Taiwan, and the U.S. In addition, the journals dominating the field were Computers & Education, followed by Journal of Computer Assisted Learning, and Australasian Journal of Educational Technology. The refined corpus was also analysed qualitatively via phenomenological method (Smith, Flowers, & Larkin, 2009), in order to identify and contextualize meaningful statements and themes. Discussion focuses on the existence of a dominant research paradigm that we divide into four investigative impulses and discuss: argumentative, comparative, relational, and analytical. Specific representative examples of each investigative impulse are thoroughly discussed and critiqued, and as a result, should be of significant value to all stakeholders, including researchers, instructors, and students, involved in forum and AOD use in educational contexts globally.     

Investigating social network patterns within an empathic online community for older people

In this paper, we study the social network structure of an online discussion board within SeniorNet, an empathic online community for older people. We apply Social Network Analysis (SNA) to analyse the communication patterns and relationships between members of the discussion board. In addition to looking at the structure of the exchanged messages within the discussion board as a whole, we also investigate associations between the communication content and the social network patterns. Our findings show distinct differences between the social network patterns of empathic and non-empathic communications. For example, members are more connected and closer to each other in the social networks that are based on empathic communication compared to non-empathic communication. Additionally our results show that the type of empathic communication (e.g. different kinds of support) is linked to the social network structure within the discussion board.     

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.     

Learning within incoherent structures: the space of online discussion forums

Abstract  Online discussion forums are an increasingly common use of new information and communication technologies in education. As a tool for promoting conversational modes of learning, it has been suggested that online discussion forums can lead to enhanced learning outcomes for students. However, there is a need to explore further the implications of the highly mediated nature of computer–based interaction on student learning within these virtual learning environments. This paper presents results from a detailed study of students' learning outcomes and patterns of interaction within an online discussion forum. The findings suggest that the typical nonlinear branching structure of online discussion may be insufficient for the realisation of truly conversational modes of learning. The paper discusses the implications of these findings in relation to students' learning.     

Knowledge construction and misconstruction: A case study approach in asynchronous discussion using Knowledge Construction – Message Map (KCMM) and Knowledge Construction – Message Graph (KCMG)

This paper introduces a methodology for analyzing the knowledge construction and misconstruction processes occurring in online asynchronous discussion for Secondary 2 (Grade 8) students. The use of purposive sampling targeting specific students in a single course forum could potentially advance understanding of these processes using Knowledge Construction – Message Map (KCMM) and Knowledge Construction – Message Graph (KCMG). This paper traced the communication patterns and knowledge construction as well as misconstruction processes of students working in groups to formulate scientific ideas. This methodology reveals the dynamics of asynchronous discussion through mapping and quantifying the electronic learning process. This will equip educational practitioners and researchers with a useful tool for describing online interaction through adoption of a measurement methodology more systematic and effective than anecdotally. The research findings suggest that self-directed learning through asynchronous discussion has to be monitored by facilitators as learners possessed misconceptions that could potentially mislead other participants.     

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.

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.     

Assessing the effectiveness of a voluntary online discussion forum on improving students’ course performance

The purpose of this study was to evaluate the effectiveness of voluntary discussion forums in a higher education setting. Specifically, we examined intrinsic forum participation and investigated its relation to course performance across two experiments. In Experiment 1 (N = 1284) an online discussion forum was implemented at the beginning of an undergraduate introductory psychology course, and measures of course performance (i.e., writing assignment grades, exam grades, and extra-credits obtained) were compared with measures of forum participation. In Experiment 2 (N = 1334) an online discussion forum was implemented halfway through a second undergraduate introductory psychology course, after an initial measure of course performance was obtained, to control for the potential confound of student engagement (e.g., students who perform better in the course use the forum more). Overall, the results showed that students who participated in the forum tended to have better performance in the course, and furthermore that participating in the discussion forum, particularly reading posts on the forum, slightly improved exam performance. This study provides empirical support for the theoretical proposition that there is a facilitation effect of discussion forum participation on course performance. The results also suggest that implementation of an online discussion forum is beneficial even if a teacher only invests minimal time on the forum.

A case study of online instructional collaborative discussion activities for problem-solving using situated scenarios: An examination of content and behavior cluster analysis

In some higher education courses that focus on case studies, teachers can provide situated scenarios (such as business bottlenecks and medical cases) and problem-solving discussion tasks for students to promote their cognitive skills. There is limited research on the content, performance, and behavioral patterns of teaching using online discussions and integrated situated scenarios. This case study empirically explored the learning process of adopting collaborative online instructional discussion activities for the purpose of problem-solving using situated scenarios in a higher education course. Thirty-two university students carried out problem-solving activities on case scenarios and problem-solving tasks assigned by the teacher on the discussion forum. Two forms of instructional activities were considered: 1) problem-solving in a given scenario and 2) problem-solving when learners play roles in a given scenario. The activities mentioned above were each implemented for a week.     

Exploration of an e-learning model to foster critical thinking on basic science concepts during work placements

We designed an e-learning model to promote critical thinking about basic science topics in online communities of students during work placements in higher education. To determine the effectiveness and efficiency of the model we explored the online discussions in two case studies. We evaluated the quantity of the interactions by looking at quantitative data of the discussion ‘threads’ and we evaluated the quality of the discussion by content analysis of the individual messages. Both the procedural facilitation of the discussion and the instrument for content analysis were based on Garrison’s ‘Practical Inquiry model of Cognitive Presence’. Furthermore, we explored the experiences of the students and moderators by interviewing them and we organised their perceptions using the framework of an activity system. On the basis of the quantitative and qualitative data we conclude that the e-learning model was successful in establishing a dialogue among a group of students and an expert during work placements at different locations. The ‘Practical Inquiry model’ was useful in facilitating a sustained on-topic discourse involving critical thinking. Although the amount of critical thinking was moderate, the results suggest ways to increase integration and resolution activities in the online discussions.     

Effects of facilitation and leadership on meeting outcomes in a group support system environment

This study investigates the effects of facilitation and leadership on outcomes of meetings involving group support systems (GSS). It extends existing GSS literature by examining the critical roles of facilitation and leadership simultaneously within a single study. A 2×2 factorial controlled laboratory experiment was conducted. A preference task, which had no objective correct answers, was employed. Ten five-person groups completed each treatment. Independent variables were facilitation (with vs without) and leadership (with vs without). During their meetings, facilitators and leaders carried out task and interactional interventions respectively. Dependent variables were measures of meeting success (post-meeting consensus, decision confidence, discussion quality, and process satisfaction). Results reveal that: (1) facilitation appears to raise decision confidence; (2) leadership appears to enhance discussion quality and process satisfaction; (3) in the absence of leadership, facilitation seems to lower post-meeting consensus; and (4) in the absence of facilitation, leadership seems to raise post-meeting consensus. These results are compared with findings from prior related studies. Implications of these results for practice are discussed.     

Research in online learning environments: Priorities and methodologies

Due to increasing demand for education and training in the information age, online learning and teaching is becoming a necessity in our future. However, lack of research goals to understand impact of online learning environments on students is a problem in research on online learning environments. We identified four main research goals to pursue in online learning environments based on their impact on learner achievement, engagement, and retention (opposite of attrition). Those goals are (a) enhancing learner engagement & collaboration, (b) promoting effective facilitation, (c) developing assessment techniques, and (d) designing faculty development programs. Current promising work in those areas is presented. Four methods that are common in the instructional technology literature are recommended to pursue those goals. Formative research and developmental research are relevant for all four. Although appropriate for any of the goals, experimental research is a better fit for goals b and c, and activity theory is useful for goals a and b.

Cognitive presence in asynchronous online learning: a comparison of four discussion strategies

Some scholars argue that students do not achieve higher level learning, or cognitive presence, in online courses. Online discussion has been proposed to bridge this gap between online and face‐to‐face learning environments. However, the literature indicates that the conventional approach to online discussion – asking probing questions – does not necessarily advance the discussion through the phases of cognitive presence: triggering events, exploration, integration and resolution, which are crucial for deep knowledge construction. Using mixed methods, we examined the contribution of four scenario‐based online discussion strategies – structured, scaffolded, debate and role play – to the learners' cognitive presence, the outcome of the discussion. Learners' discussion postings within each strategy were segmented and categorized according to the four phases. The discussion strategies, each using the same authentic scenario, were then compared in terms of the number of segments representing these phases. We found that the structured strategy, while highly associated with triggering events, produced no discussion pertaining to the resolution phase. The scaffolded strategy, on the other hand, showed a strong association with the resolution phase. The debate and role‐play strategies were highly associated with exploration and integration phases. We concluded that discussion strategies requiring learners to take a perspective in an authentic scenario facilitate cognitive presence, and thus critical thinking and higher levels of learning. We suggest a heuristic for sequencing a series of discussion forums and recommend areas for further related research.
