How teams learn to regulate collaborative processes with technological support

We examined the utility of a technologically enhanced collective regulation system for improving students’ collaborative sense-making processes, i.e., discussion quality, over time. Participants were 27 online undergraduate students enrolled in an introductory information science course. Students were divided into teams tasked with carrying out five online synchronous discussions and collective reflection activities in the system focusing on improving their processes over a ten-week period. Discussion quality was evaluated by a trained graduate student, using the same assessment rubric used by teams. Both qualitative and quantitative analysis techniques were used to examine teams’ collaborative discussion quality and socio-metacognitive processes over time. Findings suggest teams significantly improved discussion quality and used the features in the system to do so. The results also suggested that while individuals were generally inaccurate in assessing their team’s discussion quality, group assessment accuracy and identification of team’s weaknesses improved over time in select areas.

     

Exploring the attitudes,experiences and dynamics of interaction in online groups

The aim of this research was to improve understanding of the attitudes, experiences and dynamics of interaction of students working in online groups. This was achieved through a case study of postgraduate Information Studies students using the WebCT discussion board at City University in the academic year 2004–2005. Qualitative and quantitative methods were employed in combination including questionnaires, interviews, document analysis, and discussion board analysis. The latter method involved adapting an existing content analysis framework. The findings highlight the significance of group member participation, collegiality, and familiarity among group members. Students enjoyed working in online groups and found the discussion board useful, but often gave preference to other communication methods. Lecturer presence in online groups was found to be important to students, but interaction on the group discussion board was mostly student-centred. Provision of non-referential topic-related information, opinion, and solidarity were the most common types of interaction.     

The use of electronic media to develop transferable skills in science students studying anatomy

Transferable skills such as team working, communication, information gathering, critical thinking, and peer assessment are essential for graduates seeking employment in the competitive jobs market. Use of online discussion boards have grown to allow students to communicate with each other at a time and location of their choosing. This study aimed to develop transferable skills using specially developed online components supported by discussion boards and chat rooms. Students enrolled in the Human Anatomy and Histology module at the University of Manchester were put into groups of six or seven students (26 groups in total). Two e-learning components were constructed to develop transferable skills. Each group had a discussion board and chat room available to assist communication in completion of the components. Peer marking was also done on this media. Data collected showed the discussion boards were heavily utilized (average number of posts per group was 48). Eighty-three percent of students found the discussion boards useful to complete the tasks. Students felt their team building and critical analysis skills had improved. Peer assessment was well received by students. Using online discussion boards proved an excellent way to develop transferable skills in a large group of science students.     

Evaluating the impact of online discussion boards on student engagement with group work

The purpose of this study is to examine the impact of the use of an online discussion board as an assessment item on students learning performance in relation to group work based on Social Learning Theory. The study uses survey questionnaires at the beginning and end of semester together with student grade information. The data analysis consists of (1) a regression analysis to explore the relationship between student interaction and performance and (2) a repeated measures ANOVA to explore changes in attitude and perceived encouragement. Student's perceptions at the outset were found to be important as was the use of the online discussion board as a learning tool even when it is not assessed. Further, students' attitude to the online discussion board improved through the semester however the online assessment task did not encourage domestic students to be more engaged in group-based activities. In contrast, international students were more encouraged to participate in group-based activities at the end of the semester. The study has implications for online group activities in education.

Unspoken social dynamics in an online discussion group: the disconnect between attitudes and overt behavior of English language teaching graduate students

Course instructors across a wide range of disciplines have implemented computer-based learning resources such as online discussion boards. While the benefits of implementing an online discussion board in teaching have been well-documented, investigation into the social aspects of online learning environments is still needed in order to develop a deeper understanding of how group dynamics affect the overall learning experience. Accordingly, this action research project was designed to explore the perceptions of graduate students concerning the use of an online discussion board, focusing on whether the character of the interactions evidenced in the content of the discussion was reflected in the participants’ views of their experiences. The messages posted to the discussion forum were examined via discourse analysis, while the perceptions of the participants were interrogated through self-administered interviews. The results revealed that while positive group dynamics appeared to be prevalent in the discussion, the perceptions of the individual class members did not always agree with this view. In light of the findings, the researcher outlines some possible solutions for creating an online environment that is conducive to learning for members of a discussion forum with disparate levels of experience, as well as some suggestions for further research.     

Effects of discussion representation: comparisons between social and cognitive diagrams

An online discussion facilitates students’ higher order thinking in online classes, especially when adopted with the instructor’s guidance. The current experimental study examined the effects of two different discussion representation tools (social and cognitive diagrams) on students’ discussion behaviors. The social diagram emphasized interactivity of participants by illustrating who posted messages and who replied. The cognitive diagram described how discussion topic evolved by summarizing main topics discussed. Thirteen graduate students enrolled in an online graduate course participated in the study. While analyzing five instructional cases, students were asked to discuss each case in a group that the instructor assigned randomly. For each case, one group was provided with the social diagram whereas the other with the cognitive diagram. Major findings revealed both tools facilitated online discussion activities as the instructor intended: the social diagram turned out to promote socially desirable responses while the cognitive diagram produced more cognitively desirable responses. Further studies on how the two types of discussion diagrams can be integrated in online discussions will be needed.     

How do students define their roles and responsibilities in online learning group projects?

The goal of this study was to explore the processes of group role formation in online class settings. Qualitative analysis was used to code chat logs and discussion threads in six undergraduate Family and Consumer Sciences online courses that required online group projects. Four themes related to the process of group role formation emerged: testing the waters, apologies as being nice, tag – you’re it, and struggling to find one’s role. Students created roles of leader, wannabe, spoiler, agreeable enabler, coat‐tails, and supportive worker as the group process evolved over the course of the semester. Results lend support for a balance between allowing students to create and experience roles on their own and faculty assignment of roles. Questions are raised related to faculty approaches toward directing and scaffolding the group process.     

Traversing the Divide Between High School Science Students and Sophisticated Nature of Science Understandings: A Multi-pronged Approach

This study investigated the effects of a multi-pronged approach of increasing the nature of science (NOS) understandings of high school science students. The participants consist of 63 high school students: 31 in the intervention group and 32 in the control group. Explicit/reflective NOS instruction was imbedded within authentic inquiry experiences and supported by online discussions. The students in the intervention group were prompted to engage in various discussions focusing on essential tenets of NOS in an online environment that assured student confidentiality. NOS views were assessed through multiple data sources including pre- and post-intervention questionnaires as well as students’ responses to online discussion prompts. Results show that the instructional intervention used in this study which combined explicit/reflective NOS instruction with intense inquiry exposure along with ample reflective opportunities in an anonymous online discussion format led to positive learning gains in participants’ understanding the NOS aspects assessed. Implications for enhancing data collection with high school students and for promising professional development opportunities for science educators are discussed.

Scaffolding Peer-questioning Strategies to Facilitate Metacognition During Online Small Group Discussion

Meaningful discussion that facilitates reflective thinking can be initiated when learners raise thoughtful questions or provide critical feedback; however, generating effective questions requires a certain level of domain knowledge and metacognitive skills of the question-askers. We propose a peer-questioning scaffolding framework intended to facilitate metacognition and learning through scaffolding effective peer-questioning in online discussion. This framework assumes that novice students who lack domain and metacognitive knowledge can be scaffolded to generate meaningful interactions at an early stage of learning and the resulting peer-generated adaptive questions can facilitate learners’ metacognition. Thus, this study investigated the effects of providing online scaffolding for generating adaptive questions to peers during online small group discussion. A field experimental time-series control-group design was employed as a mixed model for the research design. Thirty-nine college students from an online introductory class on turfgrass management participated in the study. The findings revealed that the scaffolds were useful to increase the frequency of student questioning behavior during online discussion. For some students, the online guidance reportedly served as “a starting point” to generate questions when they had difficulty asking questions. However, the guidance did not improve the quality of questions and thus learning outcomes. The interview data indicated that peer-generated adaptive questions served a critical role in facilitating learner’s reflection and knowledge reconstruction. Further study should focus on the quality improvement of peer-generated questions while considering adaptive and dynamic forms of scaffolding and intermediate factors such as prior knowledge, metacognition, task complexity, and scaffolding type.     

Evaluating the quality of interaction in asynchronous discussion forums in fully online courses

Fully online courses are becoming progressively more popular because of their “anytime anywhere” learning flexibility. One of the ways students interact with each other and with the instructors within fully online learning environments is via asynchronous discussion forums. However, student engagement in online discussion forums does not always take place automatically and there is a lack of clarity about the ideal role of the instructors in them. In this article, we report on our research on the quality of discussion in fully online courses through analysis of discussion forum activities. We have conducted our research on two large fully online subjects for computing students over two consecutive semesters and used a grounded theoretic approach for data analysis. Our results reveal what students and instructors consider as quality interaction in fully online courses. We also propose two frameworks based on our findings that can be used to ensure effective online interaction.     

Structuring asynchronous discussion groups: Comparing scripting by assigning roles with regulation by cross-age peer tutors

The present study focuses on comparing the impact of role assignment and cross-age peer tutors on students' level of knowledge construction in 15 asynchronous discussion groups of nine students each in a first-year university course (N = 135). Content analysis was applied to analyse the level of knowledge construction in students' online postings. The results indicated that students in the tutor-supported discussions reached significantly higher levels of knowledge construction as compared to students in the role-supported group. These findings underline the value of regulation by cross-age peer tutors to foster freshmen's knowledge construction processes.     

Self-regulation as a function of perceived leadership and cohesion in small group online collaborative learning

The present study examined the relationships between perceived leadership, group cohesion, online engagement, self-regulation and learning outcomes. Data included surveys and online discussion logs from 171 students in an undergraduate online course. Through correlation analysis and structural equation modeling, the results revealed unique contributions of task and relationship leadership in small group collaborative learning. Each form of leadership may translate into greater use of self-regulation strategies that align with students’ focus on either the instrumental or interpersonal resources related to academics but may bring about a corresponding lower utilization of other types of self-regulation strategies. Further, results indicate that students’ perceptions of group cohesion provided the most robust and multifaceted positive associations with learning engagement.     

A Constructivist Model of Mentoring,Coaching, and Facilitating Online Discussions

This case study of an online graduate course determines the message characteristics of the instructor, volunteer teaching assistants, and students in online discussions, and proposes a mentoring, coaching, and facilitating model for online discussions. The researchers developed a coding system based on the literature of mentoring, coaching, and facilitating to identify the characteristics of conference discussion messages. The instructor fostered the development of volunteer teaching assistants into coaches and of student discussion facilitators into facilitators of learning. The proposed constructivist model fosters active learning, provides scaffolding for students to become facilitators of learning, and suggests creative ways for online instructors to manage different types of teaching responsibilities. Recommendations for further research are included.     

Does the discussion help? The impact of a formally assessed online discussion on final student results

While there is agreement that participation in online asynchronous discussions can enhance student learning, it has also been identified that there is a need to investigate the impact of participation in online discussions on student course performance. This paper presents a case study based on an undergraduate engineering management unit employing a formally assessed online discussion area. It was observed that while many students read a significant number of discussion postings, generally, the posting of new and reply messages occurred at the minimum level required to qualify for the assignment marks. Based on correlation and multiple regression analysis, it was observed that two variables were significantly related to a student's final unit mark—prior academic ability and the number of new postings made to the online discussion. Each new posting contributed three times as much to the final unit mark as its nominal assessment value, suggesting that the work in preparing their new discussion postings assisted students in the completion of a range of assessable tasks for the unit. The number of postings read was not significantly correlated with the final unit mark, suggesting that passive lurking in this online discussion did not significantly contribute to student learning outcomes.

The effects of communication medium on argumentation and the development of critical thinking

The aim of this paper is to compare the effects of different communication media on the quality of arguments and the development of argumentative reasoning. The study involved 73 undergraduate students. It consisted of a pre-test, an intervention session consisting of either an asynchronous online discussion or a face-to-face discussion, and a post-test. The pre-test consisted of a mini essay to ascertain participants’ opinion of smacking, and a 21-point smacking scale, where participants indicated how much they agreed or disagreed with smacking. The online group participated in a seminar discussion over a period of 2 weeks. The face-to-face group participated in the seminar discussion for a 1-h period. The seminar discussion was about the detrimental effects of smacking on children's development. One week after the seminar discussion, the post-test was administered. No statistically significant differences were found between the two conditions in terms of improvement in the quality of the students’ arguments. However, the quality of the argumentation used in face-to-face was higher than that used in the online discussions. The implications of these findings for theoretical models of collaborative activity are discussed.
