<strong>Computer</strong> <strong>Supported</strong><br />

<strong>Collaborative</strong> <strong>Learning</strong><br />

• The theoretical foundation for collaborative learning<br />

is social constructivism.<br />

• One foundational premise in SC is that children<br />

actively construct their knowledge rather than simply<br />

absorbing ideas spoken at them by teachers.<br />

• They assimilate new information to simple, pre-<br />

existing notions and modify their understanding in the<br />

light of new data.


• Instruction in this context is a process of supporting<br />

that construction rather than communicating<br />

knowledge.<br />

• Most SC models stress the need for collaboration<br />

among learners.<br />

• One Vygotskian notion, that has significant<br />

implications for peer collaboration, is that of the 'Zone<br />

of Proximal Development.'


• ZPD is defined as "the distance between the actual<br />

developmental level as determined by independent problem<br />

solving and the level of potential development as determined<br />

through problem solving under adult guidance or in<br />

collaboration with more capable peers" (Vygotsky(<br />

Vygotsky, , 1978),-<br />

• Through a process of 'scaffolding' a learner can be extended<br />

beyond the limitations of physical maturation to the extent that<br />

the "the development process lags behind the learning process".


• The broadest definition of 'collaborative learning' is that it is a<br />

situation in which two or more people learn or attempt to learn<br />

something together.<br />

• two or more may be interpreted as a pair, a small group, a class, a<br />

community, a society and all intermediate levels.<br />

• learn something may be interpreted as "follow a course", "study<br />

course material", "perform learning activities such as problem<br />

solving", "learn from lifelong work practice", ....<br />

• together may be interpreted as different forms of interaction:<br />

face-to<br />

to-face or computer-mediated, mediated, synchronous or not, frequent<br />

in time or not,


• Intuitively, a situation is termed 'collaborative' if peers are<br />

more or less at the same level, can perform the same actions,<br />

have a common goal and work together.<br />

• The second criterion is that one generally expects collaborating<br />

partners to have common goals.<br />

• The third criterion concerns the degree of division of labour<br />

among group members. Collaboration and cooperation are<br />

used distinctively according the degree of division of labour. In I<br />

cooperation, partners split the work, solve sub-tasks<br />

individually and then assemble the partial results into the final<br />

output. In collaboration, partners do the work 'together'.


• Shared knowledge is fundamentally constructed<br />

through collaboration between persons.<br />

• Different forms of interaction – that can be extended<br />

in time and space by various media and ICT tools –<br />

are the means by which people both collaboratively<br />

construct beliefs and meanings, and state differences<br />

between them.<br />

• Psychological, social and cultural processes within<br />

groups of collaborating people are the key factors in<br />

determining whether ICT tools will be accepted and<br />

successful.


• Collaboration that is mediated by ICT may proceed<br />

synchronously or asynchronously.<br />

• Another distinction concerns implicit versus explicit<br />

communication. The former refers to collaboration<br />

through use of shared information resources, such as<br />

documents, images and spreadsheets, whilst the latter<br />

is explicit communication among collaborators using<br />

audio and/or video channels, or just simple text<br />

messages.


• Appropriate communication media need to be<br />

selected for collaborative knowledge construction .<br />

• Factors that affect the selection:<br />

• characteristics of a task;<br />

• availability of telematics tools to all members of the group;<br />

• intended period of interaction;<br />

• inertia involved in switching to more appropriate media;<br />

• the ability to extend interaction in time and space.<br />

• Factors which contribute to richness are:<br />

• interactivity (the speed of reaction)<br />

• multiple cues (verbal, intonation, proxemic, , and kinetic)<br />

• language-variety (numbers, natural language, symbols, images)<br />

• socio-emotional cues (social presence, feelings)


• ICT software tools for explicit communication:<br />

•Conferencing system: questions for tutor, other<br />

participants, or experts, answers to questions, open<br />

discussions (moderated), informal chat.<br />

•Email Email<br />

•Internet Internet Relay Chat, MUD(Multi-User User Dimensions)<br />

•Low-cost desktop A/V conferencing tools: CU-<br />

SeeMe or NetMeeting conferencing tool, ISDN<br />

conferencing.


• ICT software tools for implicit communication:<br />

•Shared Shared workspace (BSCW)<br />

•Knowledge tree<br />

•Shared Shared whiteboard<br />

•Shared Shared use of software tools (word processor,<br />

spredsheets, , graphical editor)<br />

•<strong>Learning</strong> <strong>Learning</strong> management system<br />

•<strong>Learning</strong> <strong>Learning</strong> content management system


• Developments in ICT are starting to make it possible to use the<br />

tools for assisting the process of learning beyond the<br />

boundaries of the classroom.<br />

• In addition, their use will start to prepare learners for<br />

participation in a networked, information society where<br />

knowledge is the most critical resource for personal, social and<br />

economical development.


• School children and students increasingly need to<br />

acquire the individual and the group learning skills for<br />

use in learning societies and learning organisations.<br />

• They need to acquire the skills that enable them to<br />

cope with an abundance of information in order to<br />

build knowledge and thus learn from the knowledge<br />

acquired.


• <strong>Computer</strong>-supported<br />

collaborative learning requires<br />

teachers and students to adopt an educational<br />

philosophy that focuses on “knowledge<br />

building”<br />

rather than “knowledge<br />

reproduction” as the main<br />

learning activity.<br />

• This requires both teachers and students to believe<br />

in and trust a learning style that involves active,<br />

self-regulated<br />

regulated, constructive and contextualised<br />

learning by groups of students more or less<br />

independently.


• However, , not every student or teacher is used to this<br />

way of learning and for many it was not easy to learn<br />

together with other students. . In addition, , it is not easy<br />

to integrate this new educational philosophy with<br />

existing philosophies in schools.<br />

• Although other research has shown that co-operative<br />

operative<br />

learning is effective, if students have common goals<br />

and interests combined with individual accountability,<br />

in reality, , it hardly occurs within existing school<br />

practice.


• ICT support does add value by:<br />

• The easier organisation in the classroom of collaborative<br />

learning.<br />

• Better visibility of collaboration processes involving of all<br />

students.<br />

• Making communication patterns visible and structuring<br />

types of communication.<br />

• Making types of thinking visible and organising enquiry-<br />

based learning.<br />

• <strong>Learning</strong> to build knowledge and meaning collectively.<br />

• Building connections with practice; and opening new forms<br />

of collaboration with other classrooms, schools, nations,<br />

and other partners like museums and universities.


• Teachers and students do like to work through computer<br />

supported collaborative learning, but it is not easy to<br />

integrate new didactical practices into existing curricula.<br />

International<br />

exchanges seem to have a positive effect on the<br />

motivation of both students and teachers.<br />

• Teachers<br />

do not have the time for support or preparation of<br />

assignments and questions for use within a computer<br />

supported collaborative learning.<br />

• There<br />

are not enough didactical materials, , or examples of<br />

good practice to help them fulfil their new roles.


• Various<br />

positive effects can be found in computerc<br />

supported collaborative learning environments :<br />

•There<br />

is relatively consistent evidence of students showing<br />

more interest in collaborative learning.<br />

•The<br />

practises of learning and instruction change<br />

considerably.<br />

•Students<br />

work in a more self-regulating<br />

way.<br />

•The<br />

amount and quality of social interaction between<br />

teachers and students increase.<br />

•Students<br />

develop skills for using information technology<br />

and basic knowledge acquisition. They learn to access<br />

extended sources of information and motivation increase.


• There<br />

are<br />

significant advantages in using CSCL in<br />

mathematics and languages, and in process-oriented<br />

oriented<br />

measures like the quality of question raised and depth of<br />

explanation.<br />

• The suitability of the software is critical to CSCL.<br />

• There<br />

is no evidence that multimedia elements have<br />

pedagogical value without carefully planned instructional<br />

strategies and adequately educated teachers.


• Unlike the scientific communities, practising teachers<br />

do not consider highly the role of CSCL within future<br />

learning environments. This is partly due to its<br />

novelty, but also highlights that the theoretical and<br />

practical principles of computer-supported<br />

collaborative learning are too immature to be adopted<br />

as practical educational reforms.<br />

• Nevertheless, , a form of CSCL would be the most<br />

desired way to implement desired changes in<br />

educational practises like changing the educational<br />

philosophy of teachers and students.


Key Recommendations<br />

• There is a need for theoretically well-grounded<br />

development of<br />

CSCL practises and tools that are embedded in a practical<br />

educational context.<br />

• Effective infrastructures need to be established to ensure<br />

computer and computer networks are optimally utilised.<br />

Specialist IT technicians should be responsible for maintenance<br />

to enable teachers to concentrate on teaching.<br />

• Any technology needs to be adaptable to the instructional needs<br />

of teachers and to the daily realities of classroom life.<br />

• Support is also needed for the creation of electronic<br />

communities for teachers, which can aid the development of<br />

new learning methods and help establish learning communities.


• To effectively implement computer-supported<br />

collaborative learning in schools, financial support is<br />

needed for:<br />

•Adequate<br />

teacher training.<br />

•Extra<br />

hours for teachers to design assignments and<br />

questions.<br />

•<strong>Computer</strong>s<br />

and software.<br />

•Pedagogical<br />

support.<br />

• School libraries needs to become multimedia centres,<br />

central to schools in order to promote individual<br />

learning and small group work with librarians trained<br />

to be guides and tutors in the search for information


• Teachers also need training to develop technical<br />

expertise and know-how<br />

and to learn to be more<br />

effective guides and tutors.<br />

• Opening schools to activities beyond school time<br />

could facilitate the participation of Institutions in the<br />

educational community.<br />

• Educational research and the policy of national<br />

school institutions must be integrated as current<br />

research is artificially constructed and results in<br />

outcomes that scarcely affect changes.
