Knowledge awareness in CSCL: A psychological perspective

In this paper, a specific group awareness approach for CSCL settings, namely knowledge awareness, is presented. We classify knowledge awareness in relation to already well-established concepts like shared mental models, common ground, and transactive memory system in order to provide a comprehensive definition of this approach. The functionality of knowledge awareness tools aiming at fostering knowledge awareness is conceptualized in a cyclical model. Three application scenarios are presented to illustrate how knowledge awareness tools work in three different tasks. All these knowledge awareness tools have been found to be effective, that is all tools could foster knowledge awareness and led to increased learning performance.     

Group awareness tools for learning: Current and future directions

Group awareness has become an important concept since it was introduced into the field of computer-supported collaborative learning. This paper discusses current trends and future directions in this research field. It is argued that the development and implementation of tools should be complemented by systematic explorations into the mechanisms that moderate the relationship between group awareness and learning. It is suggested that variations in tool design features are a starting point for furthering our understanding of the processes involved in group awareness. Based on the contributions in this special issue, eight areas for future empirical investigations are identified. The paper concludes with some theoretical considerations on the nature of group awareness.     

Group awareness tools: It’s what you do with it that matters

This study examined the effect of using a group awareness tool on online collaboration. Furthermore, we examined whether the effect of using a group awareness tool on online collaboration is mediated by group awareness (i.e., students’ awareness of their group members’ levels of participation). To answer these questions, we determined how often and how long 107 secondary education students used the Participation-tool (PT), a group awareness tool designed to visualize group members’ relative contribution to the online collaborative process. Our analyses show that duration of PT use (how long students displayed the tool on their screens) significantly predicted group members’ participation in the online dialogue, their participation when writing collaborative texts, equality of participation within the group, and coordination and regulation of activities in the relational space (i.e., discussing the collaboration process with group members). No effect of using the PT on group performance was found. Mediation analyses showed that the effect of using the PT is only partially mediated by group awareness: an indirect effect of using the PT, via enhanced awareness of participation, on student participation during chat discussions and the collaborative writing process was found.     

Assisting students with argumentation plans when solving problems in CSCL

In CSCL systems, students who are solving problems in group have to negotiate with each other by exchanging proposals and arguments in order to resolve the conflicts and generate a shared solution. In this context, argument construction assistance is necessary to facilitate reaching to a consensus. This assistance is usually provided with isolated arguments by demand, but this does not offer students a real and integral view of the conflicts. In this work, we study the utilisation of argumentation plans to assist a student during the argumentation. The actions of an argumentation plan represent the arguments that a student might use during the argumentation process. Moreover, these plans can be integrated with the tasks needed to reach a shared solution. These plans give the student an integral and intuitive view of the problem resolution and the conflict that must be resolved. We evaluated our proposal with students of an Artificial Intelligence course. This evaluation was carried out by comparing three different assistance scenarios in which students had to solve exercises: no assistance, assistance with isolated arguments, and assistance with argumentation plans. The results obtained show that reaching consensus was easier for the students when the assistance was provided using argumentations plans.     

Assessing process in CSCL: An ontological approach

Educational technology innovations enable students to collaborate in online educational tasks, across individual, institutional, and national boundaries. However, online interactions across these boundaries are seldom transparent to each other. As a result, students are not motivated to share their best learning practices. Also, there is no singular basis on which one can compare learning practices of multiple students. In addressing these problems, we offer a solution that encourages students to record and share their learning interactions using our ontology-oriented theory-centric software tool. In doing so, students not only observe the products of their learning but also the process of how they learnt. These unique and computationally formal recordings of learning interactions not only allow educators to observe how learners learn, but also provide opportunities for learners to reflect on their understanding of meta-cognitive processes that they employed or neglected in their learning. Further, these recordings feed our software system to autonomously analyze students’ learning behaviour and to actively promote self- and co-regulation among learners. This article presents the need for such a system, the architecture of the system, and concludes with key experimental observations from software prototypes.     

Guiding knowledge communication in CSCL via group knowledge awareness

Computer-mediated collaboration is not in and of itself a beneficial setting for learning. Environments for computer-mediated collaboration need to trigger learning-productive interactions. In this paper, we propose to implement tools providing group knowledge awareness (GKA), i.e., information about collaborators’ knowledge. GKA is typically restricted in CSCL environments. A GKA tool visualizing self-assessed learner knowledge, their partner’s self-assessed knowledge, and thus the distribution of knowledge, was studied in a computer-mediated collaborative learning scenario. Thirty-eight dyads were randomly assigned to either the GKA condition (GKA tool) or a control condition (only learner’s own knowledge was visualized). Results show that the GKA tool guided learners in their collaboration and, more specifically, in designing their communicative acts. Depending on the self- vs. partner-oriented purpose of the communicative act, the learner’s own vs. the partner’s knowledge guided communication. Guided communication was a mechanism for perceived learning gains and perceived knowledge convergence. A knowledge test failed to reveal a significant difference between the GKA and the control condition. In this paper, we will discuss characteristics of GKA tools and their impact on collaboration.     

Exploring teachers' perceptions on different CSCL script editing tools

Despite the apparent maturity of the learning design field, and the variety of tooling available to support it, adoption among the teacher community (one of its alleged main targets) is still low. There is a lack of research on teachers' perception and use of different technological learning design tools, as existing evaluations are often restricted to a single tool. In order to explore whether there are common factors hampering teacher adoption, and which tool features might appeal to different teachers, more studies involving multiple authoring tools are needed. This paper provides a first step in this direction, describing a mixed methods study performed around a professional development workshop with 18 university teachers from multiple disciplines. This workshop exposed teachers to two different authoring tools (WebCollage and EDIT2), as they learned to create computer-supported collaborative learning (CSCL) designs and implement them. The findings of our interpretive study (which included questionnaires, observations, or group discussion recordings) support the idea that there is no single tool or set of features that are globally perceived as better, although our evidence also highlights certain factors as important for participant teachers – amongst others, the integration of learning designs with the ICT platforms for enactment, as well as with other tools that they already use in their everyday practice.     

Investigating Group Structure in CSCL: Some New Approaches

This paper reports some recent findings of a continuing international study that is investigating computer supported collaborative learning (CSCL) processes among a community engaged in a masters program in e-learning. This study presents results of an analysis of learning and tutoring interactions in three different groups. Each group was presented with a different model to facilitate collaborative interaction, using specially designed groupware. The empirical analysis used two compatible methods: content analysis (CA) and critical event recall (CER). The study reveals the differentiated nature of participants interactions: the results show that the groups who used the management roles and progressive enquiry models were more actively engaged in learning and tutoring interactions than the group without an additional structure (NAS).This revised version was published online in March 2005 with corrections to the cover date     

Group awareness and self-presentation in computer-supported information exchange

A common challenge in many situations of computer-supported collaborative learning is increasing the willingness of those involved to share their knowledge with other group members. As a prototypical situation of computer-supported information exchange, a shared-database setting was chosen for the current study. This information-exchange situation represented a social dilemma: while the contribution of information to a shared database induced costs and provided no benefit for the individual, the entire group suffered when all members decided to withhold information. In order to alleviate the information-exchange dilemma, a group-awareness tool was employed. It was hypothesized that participants would use group awareness for self-presentational purposes. For the examination of this assumption, the personality variable ‘protective self-presentation’ (PSP) was measured. An interaction effect of group awareness and PSP was found: when an awareness tool provided information concerning the contribution behavior of each individual, this tool was used as a self-presentation opportunity. In order to understand this effect in more detail, single items of the PSP-scale were analyzed.     

Tacit guidance for collaborative multimedia learning

Collaborative multimedia learning is a scenario placing various demands on the learners that go beyond understanding complex issues and coordinating a learning discourse. On the one hand, individuals have to mentally interrelate multiple external representations in order to understand the learning material and the underlying concepts; on the other hand, during collaboration, learners have to use the differently coded information in order to exchange conceptual knowledge. In this paper, the development and experimental evaluation of a group awareness tool (collaborative integration tool) is presented that is intended to simultaneously support both individual and collaborative learning processes during dyadic collaborative multimedia learning. The tool was experimentally compared with an integration task that already proved to foster meaningful individual learning processes. The results suggest that providing group awareness can lead to better individual learning gains by reducing demanding processes and by tacitly guiding learner interactions.     

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.     

From handheld collaborative tool to effective classroom module: Embedding CSCL in a broader design framework

The field of Computer Supported Collaborative Learning (CSCL) includes designers who emphasize effectiveness, measured via experiments, as well as designers who emphasize context and conduct qualitative research on teaching and learning practices. We conjectured that these two different emphases could be fruitful combined in a research and development process aimed at producing effective CSCL practices. We explored this possibility in a project that adapted a CSCL tool from Chile to serve as the basis of an effective 3-week classroom module for primary school mathematics in the United States. To go from tool to module, we addressed curricular fit, training materials, pedagogical guidance, formative and summative assessments, and logistical support. In conducting the project, we found that effectiveness and contextual research could be conducted simultaneously and yielded complementary insight to this design process, which enabled our project to rapidly move from the base tool towards complete classroom modules. An experiment we conducted after our design iterations showed that students who used the modules learned more about the target content, fractions. A retrospective analysis of our design process suggests that the Integrative Learning Design framework is useful for organizing the complementary components of effectiveness and contextual research in our design process.     

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.     

Facilitating peer knowledge modeling: Effects of a knowledge awareness tool on collaborative learning outcomes and processes

We report an empirical study where we investigated the effects, on the collaborative outcomes and processes, of a cognition-related awareness tool providing learners with cues about their peer’s level of prior knowledge. Sixty-four university students participated in a remote computer-mediated dyadic learning scenario. Co-learners were provided (or not) with a visual representation of their peer’s level of prior knowledge through what we refer to as a knowledge awareness tool (KAT). The results show that, providing co-learners with objective cues about the level of their peer’s prior knowledge positively impacts learning outcomes. In addition, this effect seems to be mediated by the fact that co-learners provided with these objective cues become more accurate in estimating their partner’s knowledge - accuracy that predicts higher outcomes. Analyses on the process level of the verbal interactions indicate that the KAT seems to sensitize co-learners to the fragile nature of their partner’s as well as their own prior knowledge. The beneficial effect of the KAT seems to mainly rely on this induction of epistemic uncertainty that implicitly triggers compensation socio-cognitive strategies; strategies that appear to be beneficial to the learning process.     

Strategies for collaborative writing and phases of knowledge construction in CSCL environments

Within the framework of research that describes the processes of collaborative knowledge construction in computer-supported collaborative learning (CSCL) environments, the present work has three objectives: (i) the identification of the strategies of six small groups of university students for the elaboration of written products in a CSCL environment; (ii) seek relations between the identified writing strategies and the processes and phases of collaborative knowledge construction in the groups; and (iii) relate these strategies and phases with the learning results obtained by the groups. We carried out a multiple-case study, with the analysis of four different didactic sequences, in two different virtual learning and teaching settings. In each setting, three student groups were studied, where each had to collaboratively develop between four and eight written products. For all the studied groups, the analysis enabled the identification of five types of strategies in the preparation of the elaboration of written products, and four types of phases of collaborative knowledge construction, which are interrelated and also connected with the grades that the groups obtained in each case.     

Advancing educational research on collaboration through the use of gStudy computer-supported collaborative learning (CSCL) tools: Introduction to special issue

This is an introduction to a special issue on computer-supported collaborative learning.     

Identifying a transition period at the midpoint of an online collaborative activity: a study among adult learners

This case study describes the group development in an online learning group. Adult learners enrolled in a MBA partially delivered at a distance were observed during fifteen weeks to better understand the group development of an online learning group. Both qualitative and quantitative methods were used to capture the dynamic of social interactions within the group and some affective reactions of members. The results revealed a transition period at the midpoint of the collaborative activity showing a decline of task-oriented communications, motivation and positive mood from this period. Results were discussed through models of group development validated in face-to-face environments. Some implications were proposed to facilitate online activities in computer-supported learning groups.
