Group awareness and regulation in computer-supported collaborative learning

Group awareness is of critical relevance for collaborative learning and interaction and is thus often referred to in CSCL research. However, the concept is only vaguely defined as some kind of understanding or perception of characteristics of learning partners or the collaborating group. Most CSCL research activities concerned with group awareness aim at modifying learners' awareness using so-called group awareness tools. However, there are much less attempts to measure group awareness and to conceptualize its formation. Thus, building on existing group awareness research, this article derives a conceptualization with six defining aspects of group awareness: (1) group awareness is cognitive, (2) group awareness is conscious, (3) group awareness is current, (4) group awareness is individual, (5) group awareness is social, and (6) group awareness is perceived as valid. Additionally, while it is often assumed that group awareness builds on self-regulatory skills, its role in regulating behavior and cognition within a social context is seldom explored. Thus, this article aims at defining and analyzing the concept of group awareness, specifying its relation to regulatory processes, and sketching possible research paths whilst building on, complementing, and informing tool-driven research.

     

The learning kit project: Software tools for supporting and researching regulation of collaborative learning

Computer-supported collaborative learning (CSCL) is a dynamic and varied area of research. Ideally, tools for CSCL support and encourage solo and group learning processes and products. However, most CSCL research does not focus on supporting and sustaining the co-construction of knowledge. We identify four reasons for this situation and identify three critical resources every collaborator brings to collaborations that are underutilized in CSCL research: (a) prior knowledge, (b) information not yet transformed into knowledge that is judged relevant to the task(s) addressed in collaboration, and (c) cognitive processes used to construct these informational resources. Finally, we introduce gStudy, a software tool designed to advance research in the learning sciences. gStudy helps learners manage cognitive load so they can re-assign cognitive resources to self-, co-, and shared regulation; and it automatically and unobtrusively traces each user′s engagement with content and the means chosen for cognitively processing content, thus generating real-time performance data about processes of collaborative learning.     

An exploration of students' strategy use in inquiry-based computer-supported collaborative learning

Abstract The aim of this study is to investigate students' use of cognitive learning strategies in inquiry-based computer-supported collaborative learning (CSCL). A process-oriented interview framework on cognitive activity, self-regulation and motivation, and a coding category for analysing cognitive learning strategies and cognitive self-regulation was developed. The students of an intervention group (n=18) participating in inquiry-based CSCL and a comparison group (n=8) were interviewed six to eight times during the 3 years of the study. The results derived from the mixed-method analysis of altogether 161 interviews were compared between the two groups. The results indicate that the students who participated in the inquiry-based CSCL activities reported deeper-level cognitive strategies such as monitoring, creating representations and sharing information collaboratively. The students of the comparison group reported more surface-level strategies such as memorization. However, the findings concerning the utility of CSCL inquiry on cognitive learning strategies were not uniformly positive. It was found that the students of the comparison group reported significantly more strategies under the category of content evaluation. Nevertheless, the results suggest that computer-supported inquiry-based learning can enhance the use of cognitive strategies that support learning.     

Measurement and assessment in computer-supported collaborative learning

The overall goal of CSCL research is to design software tools and collaborative environments that facilitate social knowledge construction via a valuable assortment of methodologies, theoretical and operational definitions, and multiple structures [Hadwin, A. F., Gress, C. L. Z., & Page, J. (2006). Toward standards for reporting research: a review of the literature on computer-supported collaborative learning. In Paper presented at the 6th IEEE International Conference on Advanced Learning Technologies, Kerkrade, Netherlands; Lehtinen, E. (2003). Computer-supported collaborative learning: an approach to powerful learning environments. In E. De Corte, L. Verschaffel, N. Entwistle & J. Van Merriëboer (Eds.), Unravelling basic components and dimensions of powerful learning environments (pp. 35–53). Amsterdam, Netherlands: Elsevier]. Various CSCL tools attempt to support constructs associated with effective collaboration, such as awareness tools to support positive social interaction [Carroll, J. M., Neale, D. C., Isenhour, P. L., Rosson, M. B., & McCrickard, D. S. (2003). Notification and awareness: Synchronizing task-oriented collaborative activity. International Journal of Human–Computer Studies 58, 605] and negotiation tools to support group social skills and discussions [Beers, P. J., Boshuizen, H. P. A. E., Kirschner, P. A., & Gijselaers, W. H. (2005). Computer support for knowledge construction in collaborative learning environments. Computers in Human Behavior 21, 623–643], yet few studies developed or used pre-existing measures to evaluate these tools in relation to the above constructs. This paper describes a review of the measures used in CSCL to answer three fundamental questions: (a) What measures are utilized in CSCL research? (b) Do measures examine the effectiveness of attempts to facilitate, support, and sustain CSCL? And (c) When are the measures administered? Our review has six key findings: there is a plethora of self-report yet a paucity of baseline information above collaboration and collaborative activities, findings in the field are dominated by ‘after collaboration’ measurement, there is little replication and an over reliance on text-based measures, and an insufficient collection of tools and measures for examining processes involved in CSCL.     

Enhancing non-task sociability of asynchronous CSCL environments

While from a technological perspective Computer Supported Collaborative Learning (CSCL) systems have been improved considerably, previous studies have shown that the social aspect of the CSCL is often neglected or assumed to happen automatically by simply creating such virtual learning environments. By distinguishing between students’ non-task social interactions from on-task interactions, and through a content analysis, this paper demonstrates that non-task interactions do occur frequently in CSCL environments. Furthermore, by conducting a self-reported survey, the present study operationalizes non-task sociability of CSCL environments and determines factors that affect them. The findings from the survey revealed that the sense of cohesion and awareness about others significantly impact the non-task sociability of CSCL. Furthermore, the study demonstrates that the perception of self-representation and perception of compatibility affect the sense of cohesion and awareness about others and indirectly contribute to the perceived non-pedagogical sociability of the environment. The findings of this paper can be used in future research for investigating the relationship between the non-task sociability of CSCL and other CSCL factors. The study also provides the CSCL lecturers and facilitators with a conceptual model by which sociability can be explicitly addressed in their course planning and delivery processes. And finally, this study develops and validates an instrument that guides required changes in current CSCL systems to improve the non-task social functionality of the environment.     

Teacher interventions in a synchronous,co-located CSCL setting: Analyzing focus,means, and temporality

Computer-supported collaborative learning (CSCL) environments facilitate collaboration between students. There is a growing interest in studying the role of the teacher during CSCL. This study aims to contribute to the conceptualization of teacher interventions during CSCL. A teacher and his class worked in a CSCL environment for 8 lessons. Focus and means of teacher interventions were analyzed across these 8 time points. The results show that the teacher’s behavior varied greatly between lessons and also between groups, which contradicts research that has aggregated teacher behavior to types or teaching styles. Findings consistent across time points include the predominance of the teacher’s focus on students’ cognitive rather than social activities, and a higher number of interventions in groups where student activity was higher. Suggestions are made for future research, which include studying the effectiveness of supporting tools for teachers.     

Gender-related differences in computer-mediated communication and computer-supported collaborative learning

Abstract   A question associated with the introduction of computer-supported collaborative learning (CSCL) is whether all participants profit equally from working in CSCL environments. This article reports on a review study into gender-related differences in participation in CSCL. As many of the processes in CSCL are similar to those in computer-mediated communication (CMC), studies into CMC are also included in the review. Male dominance is found to play a role in many CMC settings. A learning culture with an explicit focus on participation by all students seems to be related to a more gender-balanced participation in CMC, however. A tendency for boys to be more active participants than girls is also present in CSCL environments, but it is less pronounced than in CMC. This may be explained by the fact that participation is explicitly promoted in most CSCL environments. Gender differences in the character of students' contributions are found in both CMC and CSCL. It is concluded that in order to avoid gender-stereotyped participation and communication patterns, it is necessary to explicitly address inclusiveness as an aspect of a collaborative classroom culture. A plea is made for further research into differential participation by students in CSCL, and the effects thereof on cognitive and affective learning outcomes. Research should also focus on the question how classroom cultures can be promoted that support active participation of all students aimed at collaborative knowledge construction.     

Visualization of participation: Does it contribute to successful computer-supported collaborative learning?

This study investigated the effects of visualization of participation during computer-supported collaborative learning (CSCL). It is hypothesized that visualization of participation could contribute to successful CSCL. A CSCL-environment was augmented with the Participation Tool (PT). The PT visualizes how much each group member contributes to his or her group’s online communication. Using a posttest-only design with a treatment (N = 52) and a control group (N = 17), it was examined whether students with access to the PT participated more and more equally during collaboration, reported higher awareness of group processes and activities, collaborated differently, and performed better than students without access to the PT. The results show that students used the PT quite intensively. Furthermore, compared to control group students, treatment group students participated more and engaged more in coordination and regulation of social activities during collaboration by sending more statements that addressed the planning of social activities. However, equality of participation, awareness of group processes and quality of the group products was not higher in the treatment condition. Still, the results of this study demonstrate that visualization of participation can contribute to successful CSCL.     

Supporting controversial CSCL discussions with augmented group awareness tools

This paper describes the development of augmented group awareness tools that take mutual user ratings of their online discussion contributions as input, aggregate these data, and visually feed these data back to the members in real time, thereby informing participants about how the group as a whole perceives their contributions. A specific group awareness tool was experimentally tested in a CSCL scenario using online controversies about a physics domain. The learning material was distributed across group members to create a situation where an individual minority member with a scientifically correct viewpoint faces a majority favoring a plausible, but incorrect viewpoint. It was hypothesized that in unsupported CSCL groups an incorrect majority would dominate a correct minority, whereas in groups that were supported by an augmented group awareness tool minority influence could be strengthened by making minority contributions salient. The paper reports results in support of this hypothesis, and discusses the mechanisms leading to the benefits of group awareness tools for collaborative learning.     

The role of collective efficacy, cognitive quality, and task cohesion in computer-supported collaborative learning (CSCL)

Research has suggested that CSCL environments contain fewer social context clues, resulting in various group processes, performance or motivation. This study thus attempts to explore the relationship among collective efficacy, group processes (i.e. task cohesion, cognitive quality) and collaborative performance in a CSCL environment. A total of 75 Taiwanese college students (divided into 25 groups) participated in the study. Both quantitative and qualitative methods were applied for data analysis. The results indicate that collective efficacy significantly predicted task cohesion but not cognitive quality in the CSCL environment. For the role of group processes in performance, both task cohesion and cognitive quality significantly predicted group performance, but cognitive quality predicted better than task cohesion. In addition, for the predictive capability of prior performance, task cohesion, and cognitive quality in collective efficacy, the results showed that only task cohesion predicted subsequent collective efficacy significantly in the CSCL environment.     

Measuring perceived sociability of computer-supported collaborative learning environments

Most asynchronous computer-supported collaborative learning (CSCL) environments can be characterized as functional environments because they focus on functional, task-specific support, often disregarding explicit support for the social (emotional) aspects of learning in groups which are acknowledged by many educational researchers to be essential for effective collaborative learning. In contrast, sociable CSCL environments emphasize the social (emotional) aspects of group learning. We define sociability as the extent to which a CSCL environment is perceived to be able to facilitate the emergence of a sound social space with attributes as trust and belonging, a strong sense of community, and good working relationships. Specific environmental characteristics, which we have designated social affordances, determine sociability.     

Politeness strategies in collaborative e-mail exchanges

Computer-supported collaborative learning (CSCL) has been the subject of a wide range of studies over the last twenty years. Previous research suggests that CSCL exchanges can facilitate group-based learning and knowledge construction among learners who are in different geographical locations (Littleton, K. & Whitelock, D. (2004). Guiding the creation of knowledge and understanding in a virtual learning environment. Cyberpsychology & Behaviour, 7(2), 173). A less known fact, however, is that successful CSCL exchanges depend on the social interaction that takes place among participants. This social interaction is crucial, since it affects both cognitive and socio-emotional processes that take place during learning (Kreijns, K., Kirschner, P., Jochems, W. & Van Buuren, H. (2004). Determining sociability, social space, and social presence in (a) synchronous collaborative groups. Cyberpsychology & Behaviour, 7 (2), 156). Nevertheless, its presence in these exchanges should not be taken for granted, since there are certain barriers which may impede interaction; for example, students may not know each other previously (high social distance) and requests and offers which appear recurrently in collaborative learning messages can threaten the participants’ negative face ( Brown and Levinson 1978, 1987). In order to explore how participants overcome these barriers, we have analysed the linguistic features of politeness strategies used in the introductory e-mails exchanged between eleven students and their partners, who are students of English and Spanish, respectively. Our findings show that partners in collaborative e-mail exchanges do not use negative politeness strategies as often as we might expect in encounters where the social distance between participants is high, but they rely heavily on positive politeness strategies, especially those relating to ‘claiming common ground’, ‘assuming or asserting reciprocity’ and ‘conveying cooperation’. The presence of these strategies would indicate that fostering closeness, solidarity and cohesion becomes the priority to be achieved between the partners, instead of the expected negative politeness mechanisms whose aim is to demonstrate high social distance and, therefore, formality and impersonality.     

Socially shared regulation of learning in CSCL: understanding and prompting individual- and group-level shared regulatory activities

The field of computer supported collaborative learning (CSCL) is progressing instrumentally and theoretically. Nevertheless, few studies examine the effectiveness and efficiency of CSCL with respect to cognitive, motivational, emotional, and social issues, despite the fact that the role of regulatory processes is critical for the quality of students’ engagement in collaborative learning settings. We review the four earlier lines in developing support in CSCL and show how there has been a lack of work to support individuals in groups to engage in, sustain, and productively regulate their own and the group’s collaborative processes. Our aim is to discuss how our conceptual work in socially shared regulation of learning (SSRL) contributes to effective and efficient CSCL, what tools are presently available, and what the implications of research on these tools are for future tool development.     

Effects of an online team project-based learning environment with group awareness and peer evaluation on socially shared regulation of learning and self-regulated learning

Recently, some studies proposed methods to promote socially shared regulation of learning (SSRL) level within a team because high SSRL levels enable an effective collaboration. Meanwhile, several studies also proposed methods in online collaboration to enhance individual self-regulated learning (SRL). Notably, most existing studies focused on proposing methods and tools either for enhancing SSRL level within a team or for enhancing individual SRL. A computer-supported collaborative learning (CSCL) environment with proper supports is promising for simultaneously enhancing the SSRL level within a team and individual SRL because SSRL and SRL have an inseparable relation and mutually influence during collaborative process. Based on the existing principles and theories, this work adopts the supports of group awareness and peer evaluation in CSCL with project-based learning. Group awareness (GA) can reveal collaborative behaviour of group members and regulate their participation while peer assessment (PE), which can appraise member’s contribution, can encourage individual responsibility and refine regulatory strategies. This study finds that the proposed group awareness and peer assessment (GAPE) (i.e. the experimental class) moderately reduces the free-rider effect and enhanced SSRL level and individual SRL, compared with NO-GAPE (i.e. the control group). Furthermore, this study also confirms that the perceived SSRL level can effectively predict individual SRL.     

The role of academic motivation in Computer-Supported Collaborative Learning

In recent years, increasing attention has been devoted to virtual learning. In the last decade, a large number of studies in Computer-Supported Collaborative Learning (CSCL) have assessed how social interaction, learning processes and outcomes in virtual settings are intertwined. Although recent research findings indicate that learners differ with respect to the amount and type of discourse contributed in virtual settings, little is known about the causes of these differences. The research presented here looks into the effects of motivation of learners on their contribution to discourse using the Deci and Ryan framework of (intrinsic/extrinsic) motivation.This study of 100 participants who were randomly distributed in six groups of 14 members collaborated in a virtual setting to remediate deficiencies in economics indicates that individuals differed with respect to the amount of discourse activity. Furthermore, an integrated multi-method approach (Content Analysis, Social Network Analysis and Academic Motivation Scale) was used in order to examine the impact of academic motivation on the type of discourse activity contributed and on the position of the learner in the social network. The results indicate that highly intrinsically motivated learners become central and prominent contributors to cognitive discourse. In contrast, extrinsically motivated learners contribute on average and are positioned throughout the social network. The research results reveal that differences in academic motivation influences the type of contributions to discourse as well as the position a learner takes within the social network.

伙伴模型的建立是计算机支持的协作学习（CSCL）中寻找学习伙伴的关键。伙伴模型对学生分组的关键因素进行了较全面的建模。对伙伴模型进行了形式化的描述,并重点对动态协作信息的表示，如伙伴学习进度、知识水平、认知能力和协作能力进行了研究。     

Awareness of cognitive and social behaviour in a CSCL environment

Most distributed and virtual online environments for and pedagogies of computer‐supported collaborative learning (CSCL) neglect the social and social‐emotional aspects underlying the group dynamics of learning and working in a CSCL group. These group dynamics often determine whether the group will develop into a well‐performing team and whether a sound social space emerges. Using a theory‐based CSCL framework, two studies evaluated whether two tools, Radar and Reflector, supported cognitive, social and socio‐emotional aspects of team development, encouraging promotive interaction and group processing in the teams. While not affecting product quality, tool use did lead to groups who perceived their team as being better developed, as having higher levels of group satisfaction and lower levels of conflicts. The results support that promotive interaction and group processing was increased by using Radar and Reflector.     

Automated instructional design for CSCL: A hierarchical task network planning approach

In Computer Supported Collaborative Learning (CSCL), one of the most important tasks for instructional designers is to define scenarios that foster group learning. Such scenarios, defined as Units of Learning (UoLs), comprise different components and are organized according to pedagogical approaches to orchestrate group learning processes. Examples of UoL components are learning objects, student roles, student characteristics (e.g., background, preferences, learning styles, etc.), instructional/learning goals, and activities, among others. Thus, the instructional design (ID) of a proper UoL for CSCL is a complex task that requires practice and experience. This is particularly true when designing, developing, adapting, and customizing UoLs, taking into consideration different instructional/learning goals and individual preferences of students. This paper therefore proposes using a Hierarchical Task Network (HTN) planning approach to automate and optimize the tasks of designers. To accomplish that, we define an initial CSCL scenario as “an ID task” and “a set of information related to students and the domain to be taught.” Then we propose a model that formally describes ID for CSCL as HTN planning, where the initial CSCL scenario is adapted and refined according to student needs. In this model, the ID strategies are defined as hierarchical tasks and methods into a planning domain definition, and the initial CSCL scenario is defined as a planning problem definition. To validate our approach, we develop a CSCL courseware generator that (i) helps designers to set up an initial CSCL scenario; (ii) automatically generates a personalized UoL based on a given initial scenario; and (iii) supports the adaptation of UoLs.     

The impact of media on collaborative learning in virtual settings: The perspective of social construction

This study examines an alternative function of information sharing – social construction of meaning. Drawing on social construction, social interaction, and task closure theories, we explored the influence of both the media environment in which students are situated and the medium that group members choose to communicate with one another on the intricate relationships among breadth of information sharing, depth of information sharing, and performance of computer-supported collaborative learning (CSCL). A total of 126 students participated in the experiment – including 63 students (15 groups of four students and one group of three students) in the control and experimental groups respectively. Our findings show that most of the proposed hypotheses are supported. Intersubjective interpretation underlies groups information sharing and plays a key role in student learning performance. Evidence shows that when facing a relatively complex task in multimedia environments, students who choose to utilize a medium lower in social presence (i.e., electronic information sharing) are more likely to achieve task closure than a medium higher in social presence (i.e., verbal information sharing). This in turn leads to higher learning performance. The implications for both theory and pedagogy are also discussed.
