The aim of this study was to explore, describe and discuss factors influencing collaborative learning in small groups in an online course. Overall, students reported a positive experience of studying the philosophy of science and methods in an online context, and most of the students in our study reported that working in small groups was essential for learning complex aspects of the philosophy of science and methods. The group design characteristics that were important for the students were group size, an interrelationship between digital resources and assignments, and continuity of group members throughout the whole online course, which made them better able to complete complex assignments. These factors are in line with the factors identified by Scager (21) as being important. By working in small groups, the students experienced a level of support and understanding among their fellow students, and the fact that all assignments in the online course were group-based forced them to work collaboratively to achieve the learning outcomes.
Even though the students thought that CL was essential for their learning, not all reflected on the connection between group working processes and their learning. We found that the different working practices adopted during the online course could be differentiated into three main group working processes. These processes were not all focused on collaborative learning, and some focused more on the students’ own learning and competencies. These findings are in line with those of Johnson et al. (13), who also found variations in small-group working. The three main working processes were consistent throughout the whole online course. All three working processes involved an activity that promoted both individuals’ own learning and that of others, through knowledge sharing within the groups. An exception to this was where certain students contributed little to achievement of the overall group goal. All the working processes identified seem to be in line with the definition of collaborative learning (12, 13). However, we found that the working process involving joint responsibility (with flexible organization) was the only one to promote deep learning. In this working process, the students had shared responsibility for assignments and a common understanding of the work, with all participants acquiring greater knowledge and understanding. Through sharing responsibility, group discussions and feedback, the students not only acted as a group but more like a team (33). Among the groups using working process number 1, two approaches to the organization of work could be observed, meaning that the students often had meetings, but how they met and collaborated was different. Some groups met and distributed the work, clarifying assignments, discussing different opinions and interpretations, and coming to an agreement and common understanding. They worked on their specific set of tasks and then met again to finalize the work and complete the assignment. The other approach was to have a discussion and work together towards completion of the assignment, changing the campus group to an online group focusing on collaborating in real time. Students in groups using both forms, working together as a team to complete different aspects of complex assignments, achieved in-depth learning among all group members. This collaborative approach to working is in line with the community of inquiry framework, which emphasizes that collaboration in an online environment is essential when constructing knowledge (34). Through social and cognitive interaction, the students in our study constructed knowledge relating to the philosophy of science and methods, learning collaboratively and working together as a team. In their study, Shea and Bidjerano (35) found that both social presence and teaching presence are important for online learning and are correlated with cognitive presence. The students were socially present, and interaction was promoted. They involved themselves and their fellow students and were committed to working as a team and to the subject matter (35, 36, 21).
In working process number 2 (individual responsibility, with flexible organization), students acted more as individual contributors than as team members. The students’ preparations in advance of the assignment were insufficient, and groups started their collaboration by dividing the assignment into different sub-assignments, with students taking individual responsibility for their task. Groups used a “stapler” (as described by Scager) (21), i.e., a group member who was responsible for integrating each student’s work into a group paper. The groups did not seek to establish common knowledge or a shared understanding of the topic, and each student had individual responsibility for seeking out the necessary knowledge to complete his or her contribution to the assignment. Due to a lack of continuity in their interaction and collaboration, these groups might have lost the potential learning effect of collaboration. Johnson and Johnson (37) have called this behaviour “pseudo learning”. Although a sense of team cohesiveness is maintained through equal contributions by each member and by agreeing on the distribution of the workload, this method of organizing work does not ensure that students perceive their work as an activity which facilitates learning; rather, they see it more as a way to “get the job done”.
Students adopting working process number 3 (individual responsibility, with unorganized groups) were organized as a group but did not act as a group, and the groups did not organize themselves. Only one or a few students took responsibility and got involved in the work, while the other group members did not participate in small-group collaboration. The students who took responsibility worked and collaborated in many of the ways that the students in working process 1 did, taking responsibility, using available resources and completing the assignments. Bliss and Lawrence (38) claim that one of the biggest obstacles to group learning is students who do not participate. Our findings demonstrate that this can indeed be a problem. However, it is not the major obstacle to achievement of the learning outcomes. The students who did not participate made a choice that had consequences for their own learning and that of the other group members. The students who became involved were deprived of the benefits that could be achieved through discussion, including developing a deeper understanding of the subject matter and maximizing their potential. This has also been reported by Bliss and Lawrence (38) and Liu and Tsai (39). On the other hand, these students became well acquainted with the subject matter and were able to complete the assignments.
The groups were autonomous in terms of how and when they wanted to work. According to self-determination theory (17, 40), this should be an important factor in students’ internal motivation for learning, which should be promoted as much as possible. Our findings suggest that how students perceive the subject they are studying is related to the importance of the subject. Another key factor affecting adoption of collaborative work practices is having a common understanding of the subject and students’ expectations regarding their own level of participation in the subject. The students who organized their work using working process number 1 had a common understanding when they started collaborating on the assignment. This made the members aware of what the group should do and the expectations of one another. It is uncertain whether all members fully recognized the meaning of the subject and were internally motivated, but the way of working led to deeper learning. Students in the groups that used working process number 2 were probably mixed in terms of their views of the usefulness, but since the groups had not clarified in advance how they should work, those who emphasized fragmentation and individual responsibility had an impact. It is uncertain whether all students in these groups chose a working process that required less work and collaboration, as Scager (21) and Salomon and Globerson (22) have also pointed out. It is more likely that the working processes arose due to a lack of understanding of the consequences of different group working processes for both their own and fellow students’ learning, and the strategies used by the group at the outset persisted throughout the whole online course. The students who used working process number 3 had also not clarified the working process in advance, but in this case, the students who did not find meaning exhibited behaviour that sabotaged the entire group working process. In all three working processes, there was probably a mix of students who saw the benefit of the online course. However, through conscious choices on the part of the students, and a common understanding, group working process number 1 facilitated deeper learning, regardless of perceived meaning. This was due to the members taking responsibility and contributing to the working process and content (positive interdependence).
Strengths and limitations
This case study gave us the opportunity to explore, in depth and over time, students’ experience of collaborative learning in small groups in online courses. Since there is little research (to the best of our knowledge) on how students learn in online subjects that are part of an otherwise campus-based education, it was important for us to gain an insight into different approaches to collaboration and the significance of these for learning. This study was based on semi-structured interviews with students in relation to one case, and it is not representative of the larger population. Although the students attended several courses, the context was limited. We have described the case thoroughly so that readers can understand and recognize the parameters and relate them to their own situation (21, 42). In this way, the findings may be useful in designing and implementing similar online courses.
Another strength, yet also a possible weakness, of the study is that two of the researchers were the ones who developed the online course. This gave them an understanding of the challenges and strengths of the course, but at the same time, they had to work to maintain an analytical distance from the data. The third researcher was not directly involved in development of the course and could therefore view the data impartially.
