DIGALO is a tool for synchronous discussions using the Internet. Users located anywhere in the world may participate using a common argumentative map located on a dedicated web server.
The argumentative map shows the state of the discussion using "cards". Arguments, comments, questions and other kinds of information will be entered in the cards visible to all participants. The argumentative map can be inspected by some mouse clicks in highlighting the contributions of one specific participant. Special card forms are available to indicate special types of information.
DIGALO is configurable to fit in different discussion contexts: participant names and icons, usable card forms and their appearance, access rights for the participants. All DIGALO discussion results may be printed and exported to standard format files (GXL, CSV) for further analysis. Even deleted contributions are available. DIGALO may be embedded in other software tools like the DUNES Oasis. DIGALO also may be run in a standard mode on a local intranet server or on an Internet server. System requirements are very low, and the DIGALO performance is very fast.
Paseo (Portable Application Set for E-Organisations) enables real-time communication for collaboration through a comprehensive set of tools. On the user side, Paseo displays as an integrated desktop for running, at will, session management, chat, application/desktop sharing, vote, presence and/or a collaborative agenda.
Powerful collaborative sessions can be conducted with different moderation modes. All tools display in dedicated frames integrated into a single window, thus preventing usual multiplication of windows on one's desktop.
- The Chat offers among others multiple rooms, one-to-many as well as private conversations, moderator messages.
- Application and desktop sharing enables concurrent work on any application including Office tools, on any desktop shall it be Windows, Linux, Unix or MacOS. Session passwords, floor-control mechanisms for turn-taking, supervision and moderation ensure security and comfort of use.
- Connection of contacts, friends and colleagues can be supervised through the Presence utility.
- The Vote tool offers various modes of opinion polling, expressions of interests, and traditional votes.
- The Agenda of a session, its progress and key decisions on items can be visualised online by all participants.
Results of collaborative sessions are logged as standardised XML files, easily exploitable for post-analysis and reports.
Paseo leans on a SOA (Service Oriented Architecture) and Java developments. These services are designed for running on heterogeneous operating systems and networks, including the Internet. Most services are invoked by client applications through SOAP-XML requests. Some specific protocols are used in the particular case of application and desktop sharing. Nevertheless the latter is also Web-enabled through innovative, adaptive and dynamic configuration features making best use of software proxies.
On private networks, usage of multicast protocols and of RMI guarantees outstanding performances.
Paseo integrates an UDDI server (Universal Description Discovery and Integration) as a directory of information for defining and accessing any service. Thanks to the versatility of its technical features, Paseo can easily integrate additional tools. In the Dunes system, for instance, Digalo (for argumentation, negotiation, discussion by means of argumentative maps), is integrated as yet another tool.
Our method for collaborative learning with the support of the Digalo consists of several, interrelated components that are developed to achieve predefined learning goals. Some of these components are deliberately shaped by the teacher to promote argumentation, collaboration and learning with the support of the Digalo.
In our method we describe how teachers can "configure" the task, case, role, instructions, way of working, the tool and the planning in relation to the pedagogical goals. The method has been implemented in several secondary schools/universities in various domains.
A product of the constructivist approach, DUNES sees the individual, the interactions with his/her peers and the deep engagement in his/her activities (through appropriate tasks and tools) as central factors for learning. DUNES promotes learning by building on argumentative discussions as the learning engine, assigning to the collective generation of their graphical representation a crucial role in the process.
Introducing the DUNES system in the actual curricula depends, among other things, on our ability to train teachers / moderators in the tasks associated with the conduction of DUNES-based discussions. Indeed, the argumentative foundations of DUNES approach entail a different role of the teacher in the learning activity, and this new role should be supported by a proper preparation of the teacher. To this aim, we have devised and started to implement in schools teachers training sessions in cycles of 28 or 56 hours, for groups of up to 20 teachers each. These training cycles build on the vast experience gathered by our group in the project and in parallel activities realized during the last years. The following are basic components of the training program:
- The use of ontologies
- Case design
- Alternative approaches to discussion moderation
- Discussion evaluation
- Reflection-inducing activities
- Etc.
Introducing the DUNES system in the actual curricula depends, among other things, on our ability to design courses and lessons building on the new, graphically represented discussion-based environment proposed by DUNES. The present result materializes this condition and extends it also to include the creation of original new courses based on argumentative interaction in moderated e-discussions.
The preparation of the "DUNES-based/translated courses" will build on the vast experience gathered by our group in the project and in parallel activities realized during the last years. Because of the heavy reliance of this result on the thematic content of the course in case, the preparation work will be based, in most foreseen cases, on an intimate collaboration between our group and relevant members of the client institution (e.g., biology teachers for the preparation of a biology course).
The work will also cover the joint analysis (with the client institution) of the original course (i.e., the non-DUNES-based) in order to determine the most suitable parts or lessons for being addressed though DUNES methods and tools.
From the beginning of our R&D work in DUNES it became apparent that the quality and effectiveness of a (moderated, written e-)discussion crucially depended on the way the issue to discuss and additional related information are introduced to the pupils/students at the beginning of the discussion. This realization resulted in the "case" concept and in a thorough study to determine how this introductory function could best be accomplished. The case is an organized description of the issues to discuss and the question/s to address. It includes also initial background information about those issues, instructions to the students, relevant sources to consult (of any kind), etc. Besides clarifying the topics needed to start the discussion, a well-written case helps teachers in fostering their students' curiosity and encouraging them to enlarge and deepen their knowledge on a given subject.
The preparation of cases will build on the experience gathered by our group in DUNES and in earlier and parallel activities realized during the last years. Because of the reliance of this result on the thematic content of the specific discussion, the work will build on an intimate collaboration between our group and relevant members of the client institution (e.g., biology teachers for the preparation of a biology case).
The DUNES system provides a unique environment for conducting synchronous written discussions in Inter/intra-net. The argumentative interaction is supported by the "Digalo" tool - a graphical editor that allows its users to create and handle argumentative maps. These maps provide an easy-to-grasp picture of the discussion as it progresses - who said what, when, to whom, etc. - together with additional information on the discussion's form and structure. Digalo may be used stand-alone or in combination with other tools within "Paseo" (the client desktop), friendly accessible through the "Oasis" portal, intended to ease the utilisation of the system and the management of learning/training sessions, addressing several administrative and other functions (allocating users' rights, handling files, chat and vote facilities, application sharing, etc.).
Developed with education in mind, the "natural users" of DUNES are students and teachers and, in work environments, trainees. It was realized, however, that the system has great potential also in other settings at work, notably for decision-making (e.g., among managers under the direction/moderation of a higher-level manager) and for the conduction of (and training in) negotiation sessions. The ontologies on which Digalo builds the graphical representation of the discussions are readily customizable to these aims. All these business-oriented products - involving training, decision-making, negotiation - are covered by this "result" of DUNES.
During the implementation of Dunes, Tessera developed the software for the Dunes Oasis portal. DUNES Oasis was designed to provide central services for collaboration and all learning material for the participants offering the following major groups of services: User and Profile Management, Content Management and Case Management (Pedagogical Scenarios).
The software was developed using php and MySQL and is fully functional at this point. The software can be used either as a tool for Dunes system or as an autonomous portal, offering all the necessary services for the asynchronous part of an e-Learning environment.
Potential application sectors for Dunes Oasis software are:
- in the educational sector, combined with Digalo or any other synchronous application to provide a complete e-Learning environment used for all possible training scenarios (secondary education, college education, vocational training, adult education, etc)
- in the corporal sector, as a user and content management tool with the option to add new features or adapt the existing ones in order to tailor specific companies' needs.
