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.     

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.     

Peer modeling and innovation adoption among teachers in online professional development

This paper draws on three years of data from an online course on educational technology for practicing teachers, in which a goal was for teachers to develop a web-based application they could use in their own teaching. Based on analyses of discussion forums and teachers' course projects, we found that iterations of the course evolved over the years from being a loose association of peers involved in vastly different development projects with different tools, to a community of designers involved in a common endeavor, as more and more students chose the same open-source learning management system for their course projects. We tracked what factors seemed to affect how many and which teachers chose which development technologies, and how the process of making these choices evolved with the increased role of designed and emergent forms of peer modeling. We situate these findings in the literature on teacher professional development and technology use, arguing that existing conversations need to attend to the important role that peers play in teachers' learning and innovation adoption, particularly in online learning environments.     

How and what university students learn through online and face-to-face discussion: conceptions, intentions and approaches

Abstract This paper reports a phenomenographic investigation into students' experiences of learning through discussion – both online and face to face (F2F). The study context was a second-year undergraduate course in psychology for social work in which the teacher had designed discussion tasks to begin in F2F mode and to continue online. A combination of open-ended questionnaires and semi-structured interviews was used to investigate students' conceptions of what they were learning, their intentions and their approaches to learning through discussion. Analysis of the interview and open-ended questionnaire data identified a number of qualitatively different conceptions, intentions and approaches to learning through discussion. Associations were found between what students thought they were learning through discussions, their approaches to learning through discussion and their course grade. Students with a cohesive conception and students adopting a deep approach (to learning through online discussion) got better course grades. There was no significant difference between deep and surface approaches to F2F discussion and course grade. The outcomes of this study have implications for the design of online and F2F discussion tasks and in particular for helping students adopt richer conceptions of what they stand to gain through discussion.     

Increasing Participation in Distance Learning Courses

Web-based discussion forums are key tools in online education environments. Extant studies have shown that active participation helps drive the success of these forums. The integrated participation evaluation tool (iPET) is a Web-based application combining social network analysis and visualization to enable distance learning instructors and students to improve their participation in online discourse and so improve their overall learning experience. An analysis of the results obtained in a study using iPET in a distance learning context shows that iPET increases participation and motivation in distance learning courses without increasing facilitator workload     

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.     

Procrastination,participation, and performance in online learning environments

The present study focuses on a specific learner characteristic in the management of time – procrastination-, and its role in an online learning environment. More specifically, it was expected that procrastination would influence the successfulness of online learning and that this could be explained by the level of participation of learners in discussion forums. A study was conducted to test this hypothesis among a sample of learners taking a 10-week course on environmental and land use issues. As predicted, a negative relationship was found between procrastination and performance, and this relationship was mediated by the level of the learners’ participation in discussion forums. In other words, it appears that if high procrastinators are less successful online learners than low procrastinators, it is partly due to their lack of participation in discussion forums during the learning process. Additionally, some behavioral differences between high and low procrastinators were found in the times they decided to (re)start working at a distance, felt motivated to work on their course, and felt like dropping out of the course. To conclude, some practical implications for tutoring online activities and for stimulating participation in online learning environments have been proposed.     

Students' engagement characteristics predict success and completion of online courses

This study examined students' engagement characteristics in online courses and their impact on academic achievements, trying to distinguish between course completers and noncompleters. Moreover, this research is intended to differentiate between those who pass the final exam and those who do not. Four online courses were examined with a similar pedagogical model (N_students = 646) using learning analytics methods. The results revealed significant differences between students who completed the courses and students who did not, in all 13 variables. Completers' learning activities were more than twice as high, except for writing in the forums. Course subject and ongoing task and assignment submissions predicted course completion, whereas, in addition to these variables, engagement with course materials and reading the forums predicted final exam success, as well. Thus, the prediction of success in final exam emphasized the significant importance of engagement in various activities in the online course.     

A visualisation tool to aid exploration of students’ interactions in asynchronous online communication

Much research in recent years has focused on the introduction of virtual learning environments (VLEs) to universities, documenting practice, and sharing experience ( [Armitage et?al., 2001], [Browne and Jenkins, 2003], [Moron-Garcia, 2004] and [Weller, 2007]). Attention has been directed towards the importance of online dialogue for learning as a defining feature of the VLE.Communicative tools are an important means by which VLEs have the potential to transform learning with computers from being passive and transmissive in nature, to being active and constructivist (Pavey & Garland, 2004). However, practical methods of reviewing and analysing online communication to trace cycles of real dialogue (and learning) have proved somewhat elusive. Qualitative methods are also under-used for VLE discussions, since they demand new sets of research skills for those unfamiliar with them, and can be time intensive.This paper describes a visualisation tool to aid the analysis of online communication. The tool has two purposes: first, it can be used on a day-to-day basis by teachers or forum moderators to review the development of a discussion and to support appropriate interventions. Second, the tool can support research activities since the visualisations generated provide the basis for further qualitative and quantitative analysis of online dialogue.The visualisation software is designed to encode interaction types simply and quickly. The software was tested and then used to analyse data from a sample of forums within the Moodle VLE. The paper discusses both the method of visualisation and analysis of the online interactions as a pilot for further research analysing interaction in discussion forums.     

Effects of an online learning community on active and reflective learners’ learning performance and attitudes in a face-to-face undergraduate course

The purpose of this study was to examine the effects of an Online Learning Community (OLC) on active and reflective learners’ learning performance and attitude in a face-to-face undergraduate digital design course. 814 freshmen in an introductory digital design course were randomly assigned to one of two treatments: one offered students an OLC, which required students to discuss their assignments and readings online and participate in certain online learning activities; the other one did not offer the OLC (NC: no online learning community), but required involving students in face-to-face discussion. Individual students’ learning styles were measured using Felder and Solomon’s Index of Learning Styles Questionnaire. Results indicated that both active and reflective learners in the OLC intervention performed significantly better than those who were in the NC intervention. Results also indicated that active learners performed significantly better than reflective learners in the NC intervention; however, reflective learners performed significantly better than active learners in the OLC intervention. No significant difference between active and reflective learners’ attitudes was found. These findings indicated that OLC might be an effective means for improving both active and reflective learners’ learning performance and attitudes; however, its effects on active learners might not be as great as on reflective learners.     

Adaptive feedback generation to support teachers in web-based distance education

This work examines the application of user-adapted technologies to address problems experienced in web-based distance education. We have proposed an approach to support distance learning instructors by offering advice that points at problems faced by students and suggests possible activities to address these problems. The paper describes an original feedback generation framework which utilises student, group and class models derived from tracking data in web course management systems, and follows a taxonomy of feedback categories to recognise situations that are brought to the instructors’ attention. The results of an empirical study in an online learning course point at benefits of the generated feedback to both instructors and students. Teachers can get a better understanding of their students by knowing what problems they may be facing, when they are behind or ahead of their peers, who can help them and how, and what roles can be assigned in discussion forums. This, in turn, can have a positive effect on students who can receive feedback tailored to their needs and problems. The evaluation study points at issues that can be related in general to planning empirical evaluations of user-adapted systems in realistic web-based learning settings.     

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.     

Students’ perceptions and attitudes towards asynchronous technological tools in blended-learning training to improve grammatical competence in English as a second language

The aim of our quantitative study is to explore students’ perceptions towards some asynchronous tools to acquire the objectives of the subject of English Morphosyntax. The research was based on a sample of 358 students who were recruited from a population of 451. Participants ranged in age from 20 to 58 with an average age of 29.49 and were divided into four age groups. The results showed the students’ perceptions about the efficacy of the technological tools in Blended-learning training to improve their grammatical competence in English as a second language (L2). The students highlighted the opportunity provided to have a greater autonomy to be able to set and organize their own pace of study and individual learning. They pointed out the potentiality of the VLE implemented to supply a natural environment to learn and practice English grammar in real experiences and situations, and emphasized the benefits of the e-activities to carry out a continuous assessment and the students’ self-assessment. The present study brings some light on the students’ perceptions towards the effectiveness of asynchronous tools (podcast, videocast, online tests, online glossary and forums) in teaching English grammar to foreign language learners.     

Perceptions and experiences of,and outcomes for,university students in culturally diversified dyads in a computer-supported collaborative learning environment

The introduction of computer-supported collaborative learning (CSCL), specifically into intercultural learning environments, mirrors the largely internet-based and intercultural workplace of many professionals. This paper utilized a mixed methods approach to examine differences between students’ perceptions of collaborative learning, their reported learning experiences, and learning outcomes when they collaborated in a CSCL environment working with a culturally similar or dissimilar partner. Culturally diverse student dyads worked together to perform an online learning task in the domain of life sciences. Our sample of 120 BSc and MSc students was comprised of 56 Dutch and 64 international students, representing 26 countries. The results showed that students from an individualist cultural background had a more negative perception of collaborative learning than did students with a collectivist background, regardless of group composition. For women, working in a culturally similar dyad consisting of students from an individualist cultural background resulted in a more negative perception of collaborative learning than did working in this type of group for men or women working in a culturally similar dyad consisting of students from a collectivist cultural background. Students from an individualist cultural background achieved better learning outcomes than did students with a collectivist background, regardless of group composition. These findings suggest that cultural background adds an important dimension to collaborative learning, which requires students to manage collaboration that is not only virtual but also intercultural.     

Seeking feedback in blended learning: competitive versus cooperative student attitudes and their links to learning outcome

Emerging research has revealed the impact of electronic media usage on student outcomes, such as satisfaction and reported learning efficacy. However, little is known of its impact on measurable knowledge acquisition. Results from this study showed that participation on discussion topics through Blackboard, an electronic discussion forum, predicted multiple-choice test performance. In contrast, none of the traditional face-to-face feedback-seeking behaviours, neither with professors in class or out of class, nor among fellow students, had significant influence on test results. An examination of underlying attitudes driving both electronic and face-to-face feedback-seeking behaviours showed that competitiveness rather than cooperation drove average intensity of electronic board participation, which in turn, was related to participation across the number of electronic topical forums. The influencing role of competitiveness in this undergraduate student sample may indicate undergraduate students' lack of workplace experience, where cooperation rather than competition is often needed for workplace effectiveness. This and implications of other findings are discussed in the paper.     

Technology use,self-directed learning,student engagement and academic performance: Examining the interrelations

The widespread technology use among current college and university students has made higher educational institutions worldwide acknowledge the need of incorporating it in teaching and learning for explicit reasons. But does access and usage of technology enhance academic performance and foster student engagement in reality? Researches in the last over two decades have conjectured both the positive and negative outcomes of the students’ continuous interface with technology. Student engagement and self-directed learning (SDL) are the two other themes that have independently attracted considerable interest of researchers, ascribable to the explicit and implicit assertions that both are related to the academic success. Additionally, the relationship of technology use with these two academic behaviors have also been investigated although not very extensively. The current study aimed to inspect a path model with technology use, student engagement, self-directed learning and academic performance among undergraduate students. 761 students responded to an online survey comprising three scales: Media and Technology Usage and Attitude Scale (MTUAS), Self-Rating Scale of Self-Directed Learning (SRSSDL), and student version of Utrecht’s Work Engagement Scale (UWES-S). The results showed that use of technology has a direct positive relationship with students’ engagement and self-directed learning, however, no significant direct effect was found between technology use and academic performance. The findings point towards the complex interchange of relationships of the students’ technology use with student engagement, self-directed learning and academic performance. The implications and future research directions are discussed.     

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.     

Enhancing student knowledge acquisition from online learning conversations

This article reports a theory-driven experimental study that evaluates the effects of an annotation functionality on online social interaction and individual learning outcomes. The central hypothesis of this study is that directly addressing a part of a text by annotating it and then connecting each annotation with its related discussion can decrease coordinative interaction costs and result in a higher-quality discussion that favors greater gains in individual learning outcomes. To reach our objective, we carried out a theory-driven experimental study that compares two versions of an anchored discussion system: one with annotation functionality and one without it, both displaying the learning material side by side with its associated discussion in one window. Participants were 106 students enrolled in two sections of a blended-format course in health education. We assigned each section to a software condition. The examination of students’ online social interaction centered on a fine-grained content analysis of coordination and knowledge construction activities as well as sequential analysis of knowledge construction activities. The results indicate that annotation functionality decreased coordinative interaction costs and stimulated more elaborated discussions that favored greater gains in individual learning outcomes. Implications for research and practice are discussed.     

Reducing the spatial distance between printed and online information sources by means of mobile technology enhances learning: Using 2D barcodes

Online information sources, such as pictures and animations on web pages are frequently used for complementing printed course material in educational contexts. The concurrent use of online and printed information sources by students, however, requires going back and forth between physically separated course material, such as a course book and a computer screen, thus leading to suboptimal learning outcomes. Compatible with the principles identified by the recent theoretical frameworks for multimedia learning, mobile technology provides learners with the opportunity to bring online and printed course material close together. Mobile phones make online information available within a small desktop space, in close proximity to printed course material. The challenges that are relevant to text input methods can be overcome by the 2D barcode technology. This study investigates the use of camera-equipped mobile phone and 2D barcode technology as an alternative to the use of computer screen for complementing printed course material. The results of the experimental investigation suggest that, by facilitating the access to online information sources by 2D barcode tags on course books, mobile phones have the potential to enhance learning.
