Toward effective group formation in computer-supported collaborative learning

Group formation task as a starting point for computer-supported collaborative learning plays a key role in achieving pedagogical goals. Various approaches have been reported in the literature to address this problem, but none have offered an optimal solution. In this research, an online learning environment was modeled as a weighted undirected complete graph in which each learner was implied as a node and the relationship between them was denoted as a weighted arc. The weight of each link indicated the similarity degree between the corresponding individuals. The similarity between two students was measured as the mean of their absolute interest levels. The graph was also represented through a symmetric adjacency matrix. Then, a novel binary integer programming formulation was proposed to model the group formation problem and optimally assign each learner to the most appropriate group. The method was utilized to divide an online class of 32 learners into 8 groups of size 4. Findings indicated that the suggested model was successful in optimally solving the problem in 20.53 seconds, on average. The performance of the method was also compared with a modified version of K-means clustering algorithm. Although, the running time of the suggested technique was not as good as the clustering algorithm, it generated better outcomes in theory and in practice.     

Transformed telepresence and its association with learning in computer-supported collaborative learning: a case study in English learning and its evaluation

Telepresence has been playing an important role in a mediated learning environment. However, the current design of telepresence seems to be dominated by the emulation of physical human presence. With reference to social constructivism learning and the recognition of individuals as intelligent entities, this study explored the transformation of telepresence and its association with learning. A sample practice was performed and evaluated to understand students’ response toward the transformed telepresence. The results revealed that students recognized the presence of their peers in the transformed telepresence, and this enhanced their interest in the related activity conducted in the mediated learning environment. More importantly, students reported various cognitive processes of learning and new thoughts regarding the subject content. The findings of this study suggest that transformed telepresence creates a specific medium for human expression with particular properties and powers. This medium offers a new aspect of collaboration among participants for enhancing language learning.     

Challenges for collaborative blended learning in undergraduate students

This study reports a quasi-experiment in collaborative blended learning (CBL) with undergraduate students who, despite being in a world-leading, enriched digital environment, were new to collaboration and CBL. The mixed-methods research found that only small improvements to students’ CBL took place over time, and explanations for this are proffered. The study found that the students needed specific and intensive instruction, practice, and development in how to collaborate, both with and without blended learning. Students discovered and appreciated the benefits, pitfalls, and challenges to collaboration and CBL largely by doing it: learning from experience. Collaboration and CBL do not release teachers from their instructional and pedagogical roles; rather, they place teachers and face-to-face instruction and practice in collaboration and CBL in classrooms, at the heart of effective practice and improvements here. Implications for teaching are suggested.     

Examining peer acceptance in verbal and non-verbal interaction during computer-supported collaborative learning: implications for inclusion

This paper discusses the results of peer acceptance in a study investigating the interactions of pairs of disabled and non-disabled pupils working together on computer-based tasks in mainstream primary schools in Cyprus. Twenty dyads of pupils were observed and videotaped while working together at the computer. Data analyses were based on the collaborative nature of events for the non-verbal interaction and the functional–structural approaches for the verbal interaction. Findings gave an important insight into the interactions among disabled and non-disabled pupils working together at the computer, indicating that peer (non)acceptance came through: (1) response to the peer, articulated through verbal moves that included reply, feedback, evaluation, agree and justify, in both collaborative and non-collaborative events; (2) peer involvement, reflected in requesting involvement of the peer, mainly in collaborative and socio-emotional positive events; (3) individualistic behaviour, present through ignoring the peer in situations of on-and off-task non-collaboration; and (4) peer rejection, containing reaction and protest towards the peer in non-collaborative on-and off-task events as well as socio-emotional negative situations.     

Knowledge organization through multiple representations in a computer-supported collaborative learning environment

Computer-supported collaborative learning (CSCL) environments provide learners with multiple representational tools for storing, sharing, and constructing knowledge. However, little is known about how learners organize knowledge through multiple representations about complex socioscientific issues. Therefore, the purpose of this study was to investigate learners’ knowledge organization (KO) through multiple representations in a CSCL environment. We designed a learning unit on nuclear energy and implemented it with a group of 20 college students. The participants used a web-based hypertext KO platform that incorporated three representational modes: textual, pictorial, and concept map. The platform interlinked learners’ knowledge entries based on similar keywords. Utilizing mixed methods research we analyzed the individual entries and the knowledge base to determine KO both at the individual and the collective levels. We found that the density of the knowledge base was high; the learners mostly benefited from their text- and concept map-based entries, though the picture-based entries were also an important means for connecting entries with similar content and hence creating a dense knowledge base. Our results suggest that KO with multiple representations can create a more comprehensive knowledge base. Using distinct analytical approaches will allow CSCL researchers to better identify KO both at the individual and collective levels.

Strategizing computer-supported collaborative learning toward knowledge building

The purpose of this paper is to explore how university students can develop knowledge in small task-based groups while acquiring hands-on computer skills. Inspired by the sociocultural perspective, this study presents a theoretical framework on co-construction of knowledge and on computer-supported collaborative learning. The participants were selected from student teachers in Rwanda after a training program on searching, retrieving and exploiting web-based literature. The findings show that university students working together in small groups to acquire hands-on computer skills can adopt one of three major learning patterns: individual-led, group-led or individual-group hybrid-led. Moreover, the results indicate that the group-led framework seems to create a supportive environment for knowledge building. Nevertheless, university students showed a need for teacher support to enable them to focus on criterion-referenced reflection to regulate their learning.     

The effects of room design on computer-supported collaborative learning in a multi-touch classroom

While research indicates that technology can be useful for supporting learning and collaboration, there is still relatively little uptake or widespread implementation of these technologies in classrooms. In this paper, we explore one aspect of the development of a multi-touch classroom, looking at two different designs of the classroom environment to explore how classroom layout may influence group interaction and learning. Three classes of students working in groups of four were taught in the traditional forward-facing room condition, while three classes worked in a centered room condition. Our results indicate that while the outcomes on tasks were similar across conditions, groups engaged in more talk (but not more off-task talk) in a centered room layout, than in a traditional forward-facing room. These results suggest that the use of technology in the classroom may be influenced by the location of the technology, both in terms of the learning outcomes and the interaction behaviors of students. The findings highlight the importance of considering the learning environment when designing technology to support learning, and ensuring that integration of technology into formal learning environments is done with attention to how the technology may disrupt, or contribute to, the classroom interaction practices.     

Effects of feedback on collaborative writing in an online learning environment

The need for supporting student writing has received much attention in writing research. One specific type of support is feedback—including peer feedback—on the writing process. Despite the wealth of literature on both feedback and academic writing, there is little empirical evidence on what type of feedback best promotes writing in online environments. This article reports on research that tries to determine what type of feedback best improves the quality of collaborative writing and what the effects of feedback are on student learning in an environment based on asynchronous written communication. The results reveal that concerning the type of feedback, epistemic feedback or epistemic and suggestive feedback best improve the quality of collaborative writing performance. The nature of the feedback-giver (whether teacher feedback or teacher and peer) makes a difference to the final text only when the feedback is epistemic, or epistemic and suggestive.

Motivation in a computer-supported collaborative learning scenario and its impact on learning activities and knowledge acquisition

Addressing a drawback in current research on computer-supported collaborative learning (CSCL), this study investigated the influence of motivation on learning activities and knowledge acquisition during CSCL. Participants’ (N = 200 university students) task was to develop a handout for which they had first an individual preparing phase followed by a computer-supported collaborative learning phase immediately afterwards. It was hypothesized that in both phases current motivation (in terms of expectancy and value components) influences both learning activities and knowledge acquisition in a positive way. According to main results, only goal orientations (before learning) were associated with knowledge acquisition respectively observed learning activities during the collaborative phase. Expectancy and value components of current motivation related neither to observed learning activities nor to knowledge acquisition during collaborative learning but were in part associated with learning activities and knowledge acquisition during individual learning. The discussion addresses several possible explanations for these unexpected results.     

Assessing collaborative learning: big data,analytics and university futures

Assessment in higher education has focused on the performance of individual students. This focus has been a practical as well as an epistemic one: methods of assessment are constrained by the technology of the day, and in the past they required the completion by individuals under controlled conditions of set-piece academic exercises. Recent advances in learning analytics, drawing upon vast sets of digitally stored student activity data, open new practical and epistemic possibilities for assessment, and carry the potential to transform higher education. It is becoming practicable to assess the individual and collective performance of team members working on complex projects that closely simulate the professional contexts that graduates will encounter. In addition to academic knowledge, this authentic assessment can include a diverse range of personal qualities and dispositions that are key to the computer-supported cooperative working of professionals in the knowledge economy. This paper explores the implications of such opportunities for the purpose and practices of assessment in higher education, as universities adapt their institutional missions to address twenty-first century needs. The paper concludes with a strong recommendation for university leaders to deploy analytics to support and evaluate the collaborative learning of students working in realistic contexts.     

Learning about earthquakes: getting serious about authenticity in computer-supported learning

The discovery or re-construction of scientific explanations and understanding based on experience is a complex process, for which school learning often uses shortcuts. On the basis of the example of analyzing real seismic measurements, we propose a computer-facilitated collaborative learning scenario which meets many of the requirements for authentic learning, knowledge construction, and collaboration. The implementation of the learning environment called SeisModes is based on a general platform for supporting collaborative modeling activities. SeisModes provides a tool to allow students collaboratively learn about earthquakes and thus reduce the fears they might have concerning them. First formal evaluations showed the approach motivates students.
