Planning Collaborative Learning in Virtual Environments. La planificación del aprendizaje colaborativo en entornos virtuales

Collaborative learning has a strong presence in technologysupported education and, as a result, practices being developed in the form of Computer Supported Collaborative Learning (CSCL) are more and more common. Planning seems to be one of the critical issues when elaborating CSCL proposals, which necessarily take into account technological resources, methodology and group configuration as a means to boost exchange and learning in the community. The purpose of this study is to analyze the relevance of the CSCL planning phase and weigh up the significance of its key design components as well as examining group agreement typology and its usefulness in team building and performance. To do so, research was carried out using a nonexperimental quantitative methodology consisting of a questionnaire answered by 106 undergraduate students from 5 different CSCLbased subjects. Results prove the usefulness of the planning components and the drafting of group agreements and their influence on group building and interaction. In order to ensure the quality of learning, it is essential to plan CSCL initiatives properly and understand that organizational, pedagogical and technological decisions should converge around a single goal which is to sustain the cognitive and social aspects that configure individual and group learning

Collaborative trails in e-learning environments

This deliverable focuses on collaboration within groups of learners, and hence collaborative trails. We begin by reviewing the theoretical background to collaborative learning and looking at the kinds of support that computers can give to groups of learners working collaboratively, and then look more deeply at some of the issues in designing environments to support collaborative learning trails and at tools and techniques, including collaborative filtering, that can be used for analysing collaborative trails. We then review the state-of-the-art in supporting collaborative learning in three different areas – experimental academic systems, systems using mobile technology (which are also generally academic), and commercially available systems. The final part of the deliverable presents three scenarios that show where technology that supports groups working collaboratively and producing collaborative trails may be heading in the near future

Software Agents for facilitating collaboration among students in e-learning

Computer supported collaborative learning (CSCL) is one promising technological means to support e-learning over the Internet. However, current CSCL systems work mostly in a passive fashion and do not attempt to take active control of the collaboration. In such systems, it is the responsibility of the participating students to organize and accomplish all the activities of collaborative learning (CL). Students get little assistance from the system during the CL, e.g. the composition of a CL group, the partition of a learning task, the combination of learning outcomes, etc. This paper seeks to actively help and guide students in the CL by software agents. The CSCL over the Internet is first investigated where some challenges for the students while they are taking part in the CL are highlighted. Based on the investigation, a multi-agent architecture to facilitate the CL is proposed. Then, the implementation in one particular CSCL system, LiveNet, is presented and the supports of the agents for the CL are explored. At the final are the conclusions of the paper and some outlooks

Collaboration and the Net generation: The changing characteristics of first year university students

This paper reports on the first phase of research that investigates the Net generation entering university. The paper focuses on claims about the Net generation’s relationship to collaboration and cooperation and the ways that this relationship is associated with technological rather than social processes. Based on a survey of first year students in five universities across a range of subjects and disciplinary areas, the paper concludes that we should be cautious about the claims that have been made about Net generation learners. It suggests that broad brush approaches to generational changes obscure the subtle but important differences between students. It also suggests that claims that there has been a step change in attitudes takes attention away from the kinds of choices that might be necessary in relation to variations that are indeed taking place amongst new cohorts of students

A context for collaboration: The institutional selection of an infrastructure for learning

This paper discusses the role of institutional issues in the deployment of infrastructures for learning and the ways in which they can impact on the range of choices and opportunities for collaboration in university education. The paper is based on interviews with 12 key informants selected from relevant staff categories during the deployment of a new institutional infrastructure in a large UK based distance learning university. It is supplemented by participant observation by the author who was part of a group of advisors tasked with working with the project team developing and deploying the new infrastructure. The paper investigates the development and deployment of the infrastructure as a meso level phenomena and relates this feature to the discussion of emergence and supervenience as features of social interactions in education

A constructivist framework for online collaborative learning:adult learning and collaborative learning theory

The purpose of this chapter is to review and discuss theoretical perspectives that help to frame collaborative learning online. The chapter investigates literature about the type of learning and behavior that are anticipated and researched among participants learning collaboratively and discusses how these attributes explain computer-supported collaborative learning. The literature about learning is influenced by perspectives from a number of fields, particularly philosophy, psychology, and sociology. This chapter describes some of these perspectives from the fields of cognitive psychology, adult learning, and collaborative group learning. Recent research into computer-supported collaborative learning that applies these theories will also be discussed.<br /

The role of scaffolding and motivation in CSCL

Recent findings from research into Computer-Supported Collaborative Learning (CSCL) have indicated that not all learners are able to successfully learn in online collaborative settings. Given that most online settings are characterised by minimal guidance, which require learners to be more autonomous and self-directed, CSCL may provide conditions more conducive to learners comfortable with greater autonomy. Using quasi-experimental research, this paper examines the impact of a redesign of an authentic CSCL environment, based upon principles of Problem-Based Learning, which aimed to provide a more explicit scaffolding of the learning phases for students. It was hypothesised that learners in a redesigned ‘Optima’ environment would reach higher levels of knowledge construction due to clearer scaffolding. Furthermore, it was expected that the redesign would produce a more equal spread in contributions to discourse for learners with different motivational profiles. In a quasi-experimental setting, 143 participants collaborated in an online setting aimed at enhancing their understanding of economics. Using a multi-method approach (Content Analysis, Social Network Analysis, measurement of Academic Motivation), the research results reveal the redesign triggered more equal levels of activity of autonomous and control-oriented learners, but also a decrease in input from the autonomous learners. The main conclusion from this study is that getting the balance between guidance and support right to facilitate both autonomous and control-oriented learners is a delicate complex issue

Student participatory role profiles in collaborative science learning: Relation of within-group configurations of role profiles and achievement

During collaborative learning, students tend to spontaneously enact different participatory roles that may significantly affect collaborative learning processes. Only few empirical studies to date have investigated groups as systems based on emerging roles and role profiles of the participating students, and how emerging role profile configurations affect achievement. This exploration of students' self-adopted roles investigated the relationship between role profile configurations and achievement. The statistically driven identification of role profiles was based on fine-grained observations of student groups' interactions in two distinct collaborative science-learning settings. While higher achieving groups typically exhibited versatile science-oriented role profile configurations, opinion-based configurations prevailed in lower achieving groups. Although role profiles with a social orientation were rare, a student with a distracting profile can have a significant influence on group work. Consolidated by in-depth case examples, the findings highlight the importance of understanding how collaborating groups' emergent role profiles dynamically interact during collaborative learning and how different role profile configurations relate to achievement

Supporting Peer Help and Collaboration in Distributed Workplace Environments

Special Issue on Computer Supported Collaborative LearningIncreasingly, organizations are geographically distributed with activities coordinated and integrated through the use of information technology. Such organizations face constant change and the corresponding need for continual learning and renewal of their workers. In this paper we describe a prototype system called PHelpS (Peer Help System) that facilitates workers in carrying out such "life long learning". PHelpS supports workers as they perform their tasks, offers assistance in finding peer helpers when required, and mediates communication on task-related topics. When a worker runs into difficulty in carrying out a task, PHelpS provides a list of other workers who are ready, willing and able to help him or her. The worker then selects a particular helper with PHelpS supporting the subsequent help interaction. The PHelpS system acts as a facilitator to stimulate learning and collaboration, rather than as a directive agent imposing its perspectives on the workers. In this way PHelpS facilitates the creation of extensive informal peer help networks, where workers help one another with tasks and opens up new research avenues for further exploration of AI-based computer-supported collaborative learning.
