Interaction and cognition in asynchronous computer conferencing

This paper is based on a multiple-case study of the learning process in three asynchronous computer conferences. The conferences were part of the distance learning component in doctoral degree courses in computing technology in education offered at an American university. The conferences were analyzed from a number of perspectives, the emphasis in this paper being on the dimensions of interaction and cognition. Although similar interaction patterns were identified in the three conferences, each conference also showed distinctive patterns, which were related to factors such as instructor moderation, structuring of the instructional task and the emergence of student moderation of the discussion in specific threads. Three models were used to evaluate cognition: Bloom's Taxonomy (Bloom, Engelhart, Furst, Hill, & Krathwohl, Handbook 1, Cognitive Domain, Longman, London, 1956), the SOLO Taxonomy (Biggs & Collis, Evaluating the Quality of Learning: The SOLO Taxonomy, Academic Press, New York, 1982) and the Practical Inquiry Model of Cognitive Presence (Garrison, Anderson & Archer, The American Journal of Distance Education 15(1)7, 2001). Correspondences were found among the three models and all three conferences were characterized by higher-order thinking. When higher-order thinking was defined in terms of the distributed cognition occurring during practical inquiry, the advanced phases of cognition were found to be related to synergistic interaction in the conference threads. The findings serve to define the knowledge-building processes occurring in asynchronous computer conferencing. They also lend support to views of learning as dialogical and to social constructivist approaches to learning and teaching.     

Critical incident-based computer supported collaborative learning

Practitioners are regularly confronted with significant events which present them with learning opportunities, and yet many are unable to recognise the learning opportunity these significant events present. The ability to recognise a learning opportunity in the workplace and learn from it, is a higher-order cognitive skill which instructors should be seeking to develop in learners. The study reported in this paper developed, implemented and evaluated the efficacy of a model of teaching and learning which embodied the essence of this focus, which is entitled Critical Incident-Based Computer Supported Collaborative Learning (CI-CSCL) and it is driven by the premise that much greater benefit can be derived from the experiences of practitioners in authentic environments by enabling them to share their individual learning experiences among the student cohort. The study was carried out within a course in the Post-Registration Nursing (RN) degree program at the University of Southern Queensland in AUSTRALIA.Data reported in this paper was drawn from two sources; (a) students' reflections on critical incidents; and (b) a semi-structured evaluation. The reflections were examined for attributes we were attempting to engender in learners with our model of learning. The semi-structured evaluation sought open-ended responses. The analyses of data collected showed evidence of participants: seeking and offering comments; reflecting on critical incidents; describing what happened and assessing their own actions; making the connection between theory and practice; identifying and defining problems; and adopting a more structured and systematic approach to problem solving.     

The Effects of Conversational Language on Group Interaction and Group Performance in Computer-Supported Collaborative Argumentation

This study examined the effects of conversational language (e.g., asking questions, inviting replies, acknowledgments, referencing others by name, closing signatures, ‘I agree, but’, greetings, etc.) on the frequency and types of responses posted in reply to given types of messages (e.g., argument, evidence, critique, explanation), and how the resulting response patterns support and inhibit collaborative argumentation in asynchronous online discussions. Using event sequence analysis to analyze message-response exchanges in eight online group debates, this study found that (a) arguments elicited 41% more challenges when presented with more conversational language (effect size .32), (b) challenges with more conversational language elicited three to eight times more explanations (effect size .12 to .31), and (c) the number of supporting evidence elicited by challenges was not significantly different from challenges that used more versus less conversational language. Overall, these and other findings from exploratory post-hoc tests show that conversational language can help to produce patterns of interaction that foster high levels of critical discourse, and that some forms of conversational language are more effective in eliciting responses than others.     

Assessment of collaborative learning experiences by graphical analysis of wiki contributions

The widespread adoption of computers and Internet in our life has reached the classrooms, where computer-supported collaborative learning (CSCL) based on wikis offers new ways of collaboration and encourages student participation. When the number of contributions from students increases, traditional assessment procedures of e-learning settings suffer from scalability problems. In a wiki-based learning experience, automatic tools are required to support the assessment of such huge amounts of data. In this work, we present StatMediaWiki, a tool that collects and aggregates information that helps to analyze a MediaWiki installation. It generates charts, tables and different statistics enabling easy analysis of wiki evolution. We have used StatMediaWiki in a Higher Education course and present the results obtained in this case study.     

Patterns of debate in tertiary level asynchronous text-based conferencing

Argumentation can be defined at different levels and serve different purposes, but its role in knowledge understanding and construction has given it a central place in education, particularly at tertiary level. The advent of computer-supported text-based conferences has created new sites where such educational dialogues can take place, but the quality of the interaction and whether it is serving its educational purpose is still uncertain. This paper reports on a framework of analysis that has been developed to illuminate the arguing process within an asynchronous electronic conferencing environment, showing how it is both similar to, and different from, argumentation in the more traditional forums of multi-party, face-to-face discussion and traditional written essays. The framework develops earlier work by the authors and is applied to two electronic conferences within the same postgraduate course, comparing overall patterns of argumentation. Findings are presented on the extent to which the technology of electronic conferencing shapes and supports students’ participation in academic literacy practices relating to argumentation, proposing, at the same time, that the teaching strategy adopted by the lecturer is also an important variable.

The impact of computer supported collaborative learning on internship outcomes of pharmacy students

This article focuses on an evaluation of the impact of an innovative instructional design of internships in view of a new integrated pharmaceutical curriculum. A key innovative element was the implementation of a computer-supported collaborative learning environment. Students were, as part of their formal curriculum, expected to work in a systematic and collaborative way in discussing and solving real-life cases. Students in the role condition were assigned specific roles. The cases were an additional critical variable in the study. The results of the study demonstrate that both independent variables (role assignment and cases) have a significant impact on levels of knowledge construction and, especially, on the attainment of objectives of the new integrated pharmaceutical curriculum.     

Teaching collaborative skills with a group leader computer tutor

This paper discusses how a group leader computer tutor may aid students in learning collaborative skills in a co-operative learning environment. However, students need to learn collaborative skills and practice using them. The group leader computer tutor discussed in this paper is designed on the principles of co-operative learning, intelligent tutoring systems and computer-supported collaborative work within an intelligent collaborative learning system (ICLS). The group leader aims to facilitate group work on the task level and to teach students how to use collaborative skills in the discussion level as students work on networked computers in the Jigsaw method of co-operative learning. The ICLS and its group leader were used by two classes at a liberal arts university. Qualitative research shows that the students' co-operative attitudes changed and academic achievement improved from pre- to post-treatment. Students, especially, used the communication skill of openness in comment type discussions. The students enjoyed working collaboratively through the ICLS and their teachers thought that the experience was valuable for them.     

Agency online: trends in a university learning course

This article aims to investigate how university students perform agency in an online course and whether the collaborative nature of the course affects such expression. A total of 11 online web forums involving 18 students (N = 745 posts in total) were qualitatively analysed through the use of a codebook composed of five categories (individual, interpersonal, epistemic, transformative and collective) and several sub-categories purposely developed for the sake of this research. The results show that each category follows a specific path, although two events – the re-mixing of the groups and the assumption of the peer-tutor role – particularly affected the evolution of trends. Although this study needs further development, the authors believe that an in-depth understanding of the nature of agency, including how to analyse it as well as empower it when implementing blended educational activities, engages relevant theoretical and pedagogical issues.     

Content analysis of online discussion on a senior-high-school discussion forum of a virtual physics laboratory

In this study we content analyzed the online discussion of several senior-high-school groups on a forum of a virtual physics laboratory in Taiwan. The goal of our research was to investigate the nature of non-course-based online discussion and to find out some useful guidelines in developing such discussion forums for learning purposes. We adapted Henri’s framework and models (1992) for our analysis. The content analysis was conducted in terms of participation rate, social cues, interaction types, and cognitive and metacognitive skills. In this study, we compared the result patterns of two discussion conditions (‘required’ (R-) condition versus ‘non-required’ (NR-) condition) of a non-course-based discussion forum and investigated how the quality of message content changed in the processes of discussion. In the R-condition, participants were required to reply to the thread before they were allowed to read other messages on the forum, whereas participants in the NR-condition were not restricted to this demand. The results showed that for both conditions, the most frequently involved interaction type was ‘direct response’, and the most frequently used cognitive skill was ‘elementary clarification’. Fewer participants of the R-condition strayed from the subject under discussion in comparison to the NR-condition. However, larger percentage of message content containing metacognitive components was found in the NR-condition. When taking the sequences of postings into account, we found that for the R-condition, the percentage of metacognitive component in the message content tended to increase in the up-third postings, whereas for the up-third postings of the NR-condition the percentage of non-cognitive components substantially increased. Overall, the results of our study indicated that the way in which participants used cognitive and metacognitive skills during the discussions was related to the discussion conditions. The initial requirement of reply fostered the use of cognitive skills, but it did not necessarily induce the use of high-level cognitive or metacognitive skills. We concluded that beside the discussion conditions the moderators’ guidance would be influential in determining the quality of online discussion on a non-course-based discussion forum. in final form: 19 August 2005     

Content analysis in empirical social research

An overview of the development of empirical content analysis is presented. Its development relevant to educational research from classical to computer-aided content analysis is traced. The history of hermeneutic text interpretation is included as well as the early developments in the analysis of manifest content of communication. The controversy between quantitative and qualitative schools of research is discussed. A theoretically grounded, practicable model of content analysis is introduced, which fulfills the criteria of empirical social research.

Opening dimensions of variation: An empirical study of learning in a Web-based discussion

The discussions held in specifying an automaticvehicle as a project in a distance work-relatedcourse are in focus for an analysis of learningin networked discussions. Learning ischaracterised as coming to experience things indistinctly new ways, in keeping with theunderlying phenomenographic research approachfor the study. Group discussions are seen asone feature in the experience of, and theformation of, the context for learning, in anexperiential interpretation of activitysystems. The analysis has led to theidentification of pivotal contributions todiscussions that can be said to afford learningwithin the group, in the sense of openingdimensions of variation around criticalfeatures of the task. This is developed toproduce a taxonomy of contributions, withparticipatory, factual, reflective and learningcontributions, suggested to be necessary,though not sufficient, conditions for learning.The taxonomy is illustrated and discussed, asare its implications for tutoring in networkedcourses of this type.     

Facilitating debate in networked learning: Reflecting on online synchronous discussion in higher education

Small-group collaborative learning in whichstudents have opportunity for criticaldiscussion is a key element of effectiveteaching and learning in Higher Education. Providing this sort of education throughNetworked Learning (NL) is challenging. Research in Computer Mediated Communication(CMC) is revealing that facilitating effectiveuse of these tools depends on encouragingstudents to take many different dialogue roles.Our hypothesis was that asking post-graduatestudents to reflect on the kinds of role theyshould take in synchronous online discussionwould encourage adoption of such roles. A``role-play' activity was introduced topost-graduate students who used a VirtualLearning Environment (VLE) as part of theircourse. Initial results showed that bothdistance and face-to-face students, nativespeakers (NS) and non native speakers (NNS),working collaboratively on the same coursethrough the VLE, had comparable outcomes onessay assignments and that NNS and distancelearners slightly outperformed face-to-facestudents in their group work. Moreover, therewas evidence that the facilitation technique ofraising student awareness of roles waseffective in helping (at least some) studentsmanage synchronous online discussion moreeffectively, improving the overall coherence,focus and depth of discussion.     

Modelling cognitive style in a peer help networkt

I-Help is a computer system that assists learners as they try to solve problems while learning a subject. I-Help achieves this by supporting a network of peersthat help each other out. One component ofI-Help selects appropriate peers to assist astudent, and then sets up a one-on-one peerhelp session between the helper and the helpee.The matching of helper to helpee takes intoaccount factors such as a potential helper'sknowledge of the topic of the helpee'squestion; their availability and eagerness tohelp; and their general helpfulness. Recentwork has developed a cognitive style componentto supplement these attributes, which enablesconsideration also of the suitability of ahelper's cognitive style for answering thehelpee's question. This paper describes howmodelling individuals' cognitive style canusefully supplement other user model data in apeer help network, and describes how thisinformation is obtained in I-Help.

Review of computer mediated communication research for education

This research review examines recent developments in computer-mediated communication (CMC) research for educational applications. The review draws on 170 recent research articles selected from 78 journals representing a wide range of disciplines. The review focuses on peer-reviewed empirical studies, but is open to a variety of methodologies. The review is divided into two sections addressing major areas of current research: (a) general CMC research in education, and (b) factors affecting computer-mediated learning. The review covers a variety of key research areas revolving around CMC in education, including, media effect and comparison, on-line courses and networks, course and program evaluations, learning and learning processes, problem solving, writing, decision-making, argumentation, group decision-making, group dynamics, peer evaluations, gender differences, anonymity, teaching practice effects, technology integration, teacher styles and characteristics, socio-cultural factors, and professional development effects. Findings suggest partial advantages of CMC in writing, task focused discussion, collaborative decision-making, group work, and active involvement in knowledge construction during group interactions. Other research findings revealed influences of peer interaction, group composition, group cohesion, goal commitment, group norm development, and process training, mixed-sex groups, and virtual cross-functional teams. Mixed-findings are revealed for performance advantages of computer-mediated versus face-to-face learning environments on various tasks and for the presence of gender differences in computer-mediated environments.     

A content analysis of student/instructor communication via computer conferencing

The focus of this study centers upon an analysis of instructor and student postings on the Electronic Forum (EF) during a one-semester undergraduate phonetics course. Sixty-one students were invited to participate in a class computer conferencing project to discuss questions about the course content and assignments, share ideas with others, and respond to comments made by their peers and the instructor. The content of each student's and instructor's posting was analyzed to determine the number and type of topics discussed. Students wrote about 340 topics in 143 postings; the instructor wrote 124 topics in 23 postings. These topics were placed in categories and analyzed with respect to the postings made during the first and second half semester. Four interactive communicative Category Clusters were identified. These Clusters show interaction trends between students and instructor and resulting accommodations made by both students and the instructor. The advantages of using an electronic forum to enhance student learning, to improve classroom activities, and to empower students to take more active roles in their learning, are discussed.
