Gagne, Briggs, & Wager, 1994; Smith & Regan, 1993) are linear or structured and based on traditional principles of objectivism-positivism.
Followingthecontemporarylearningtheories, there seems to be a transition from a teacher-cen-
tred to a student-centred approach, from teaching to learning, from individual learning, to a learning derived from a collaborative environment, within the context of a learning community. Such considerations originate from the field of cogni-
Blending Interactive Videoconferencing and Asynchronous Learning in Adult Education
tive theories of social interaction (i.e., distributed cognition theory [Pea, 1995, & Salomon, 1995] and activity theory [Engestrom, 1987]).
In the recent years there have been proposals recommending the designing of a Web-based learning environment (Graham, McNeil, & Pettiford, 2000; Horton, 2000; Jolliffe, Ritter, & Stevens, 2001; Karpov & Haywood, 1998). Most of them converge as to the point that the important elements of designing a Web-based learning environment are the learning goals, the learning activities, the role of tutors and students, the connection between learning goals and teaching material, the assessment, and the social content of learning.
Roberts (1995) suggests a user-friendly model called ‘a template for converting classroom courses to distributed, asynchronous courses’ (http://www.unc.edu/cit/iat-archive/publications/ roberts/template.html), which emphasises the definitionoflearninggoals,theadaptationofthe teaching material to the defined learning goals, the choice and best combination of the appropriate learning theories, the choice of technological means,and,finally,theformationofacollaborative environment.
In a systemic approach towards the designing of a Web-based learning environment (Cobb, 1994; Jonassen, 1992; Philips, 1995) the model of problem solving is adopted and includes four phases: analysis, designing, development-imple- mentation, and assessment-revision.
Since the early 90s (Salomon, 1992; Kagan, 1994) emphasis has been given on the designing of collaborative Web-based environments. These attempts focus on the fact that the student should becapableofsolvingproblems,collaboratingwith others, being responsible for their pacing, and being rewarded for achieving their goals within the group (Reiser, 2001). However, several issues are raised which are connected to the development (Jonassen, 1997; Van Berlo, 2000) and the quality of such systems regarding the achievement of the set learning goals (Hakkinen, Järvelä, &
Byman, 2001).
The formation of collaborative Web-based learning environments offers a great many significantadvantages(Connell,1994).However,its success depends to a great extent on the designing of an environment which aims at the encouragement and support of the active participation of students (Mason & Bacsich, 1998).
The most recent research (Strijbos, Martens, & Jochems, 2004) recommends the following six stepsintheformationofacollaborativeWeb-based learningenvironment:definingthelearninggoals, selecting the expected interaction, selecting the responsibilities of the human resources, deciding whether it will be a structured collaborative environment or not, and finally, defining the technological means to support the application.
fundamentals of designing a web-based de environment
The designing of a Web-based learning environment should be based on pedagogical principles, the understanding of learning material and the set learning goals, and definitely, the awareness of the way advanced Internet technologies can contribute to attaining these goals (Colis & Moonen, 2001).
The designing of a Web-based learning environment requires special attention, as we need to adhere to DE principles when we develop the teaching material, plan our teaching strategy, and decide on the combination of the technological means to support the attainment of the set learning goals (Anastasiades, 2002). In the proposed designing we follow the basic principles which should determine a learning environment according to the methodology of the American Distance Education Consortium (http://www.adec.edu).
•A distance learning environment should be regulated by clear learning goals and focus on predefined expected outcomes, consid-

•The student should be encouraged to actively participate throughout the learning course, associating learning by doing, learning by reflection, case-learning study, and learning byexploring.Relatinglearninggoalswithreal life learning experiences is a major priority.
•The learning environment should combine the use of technological means in order to attain the set learning goals considering the different learning styles of students. The selection of the technological means depends on the nature of content, the access to technology of the learning group, and the general educational philosophy of the teaching staff.
•The learning environment should encourage interaction among the human resources by ensuring the appropriate conditions and
Table 2. Learning events based on interaction
actively supporting the development of communities which share common interests with the aim of achieving collaborative learning.
Strong emphasis is placed on interaction, as it is regarded as one of the fundamental factors in achieving the learning objectives. The proposed interactive environment implements the theory of three types of interaction (Moore, 1989) and that of Paulsen’s methodology (1977) and is illustrated in Table 2.
Phases of development of a web-based learning environment
The designing of a Web-based learning environment proposed in this chapter applies the methodology of dividing the process into phases and implements the relevant approaches.
This model recommends four phases of development: analysis, designing, application, and assessment.
Each phase comprises of specific actions and demands the most of the human, learning, and technological resources of the system.

ing but to come into supplementary operation (Anastasiades, 2006b; Hanor & Hayden, 2003).
Berge και Mrozowski (2001), who studied educational videoconferences from 1990 since 1999, concluded that the most important issue for the successful outcome of a videoconference was not only the technology provided but also the educational methodology that was constructed and followed by the educators. IVC have to create an environment in which social dialogue, discourse and interaction, problem-based learning, negotiation of meaning, and construction of knowledge must be the basic goals of the whole process, so constructivism is the appropriate pedagogy for
videoconferencing (Jonassen, Howland, Moore, & Marra, 2003; Anastasiades 2006b).
TheproposedIVCpedagogicalmodelrequires a specific pedagogic approach (Anastasiades,
2003c, 2006a) designed to achieve the best possible results which include:
1.The development of the IVC pyramid
2.The delineation of a communication model
3.The designing of classroom architecture
4.The selection of a technological infrastructure
5.The design of an organisational and supporting model
6.The evaluation methodology

A4 Introductory VC: The introductory VC course will be organised by the instructor and will be attended by both the students of the instructor’s class and the students form remote classrooms. At a scheduled time the two classes will be ready for action. In this phase we need to familiarise as smoothly as they can the instructor, the motivators, and the students with the concept of VC.
A5 Evaluation:
•Students’ evaluation (evaluation of knowledge,experiencefromtheteaching, etc.) by the teachers.
•Teachers’ evaluation (noting down problems, ways of solving them, alternate approaches, etc.) by the teachers themselves in cooperation with other teachers, specialists and so forth.
•Evaluation of the VC (satisfaction, interactivity, familiarising, etc.)
Creation of the Virtual Classroom
(Stage B)
The creation of an interactive learning environment is attempted in this phase, where the whole VC course period will be covered by lecturing, questions, and interactive dialogues in order to negotiatetheadultlearnersneeds,findouttheprior knowledge,andtostartbuildingupthe knowledge construction. The instructor must have the ability tomanagethewholevirtualclassroomandthemotivators to be active to the other classrooms. This phase is aiming at the creation of the necessary conditions in order to unfold all the activities that take place in a conventional classroom. Teachers, motivators and students familiarise themselves with the idea of the virtual classroom.
Evaluation:
•Students’ evaluation (evaluation of knowledge, experience from the teaching, etc.) by the teachers.
•Instructor’ evaluation (noting down problems, ways of solving them, alternate approaches, etc.) by the teachers themselves in cooperation with other teachers, specialists, and so forth.
Collaboration by Distance: Development of Joint Activities
Between Remote Classrooms.
(Phase C)
In this phase we have an attempt to create an open collaborativeenvironmentbetweenthestudentsof the remote classrooms, by creating work groups that will be in collaboration from a distance, in order to carry through a joint activity. During this phase, the students are the leading actors in the new collaborative environment, while the teacher and the motivators play a rather supervis- ing-guiding role, interfering whenever they find it necessary.
In this stage we try to engage teachers and learners in collaborative learning activities according to research and practice in computer supportedcollaborativelearning(Dillenbourg,Baker, Blaye, & O’Malley, 1996; O’Malley, 1995). According tothe proposed methodology participants engagecollaborativelyinknowledgeconstruction and negotiate with one another to reach a common shared understanding about a particular topic in order to achieve a joint project (Anastasiades 2003a; Dillenbourg & Traum, 1999)
Evaluation:
•Self-evaluation of the students (evaluation of the procedure by the students themselves).
•Students’ evaluation by the teachers (noting down problems, ways of solving them, alternate approaches, etc.) by the students themselves in cooperation with other students, specialists, and so forth.
Blending Interactive Videoconferencing and Asynchronous Learning in Adult Education
Collaborative Argumentations (Stage D)
Each group of the local and distant sites presents theircollaborativeprojectstothevirtualclassroom and the facilitator organises an interactive collaborative argumentation. Learners have to explain their position, focusing their cognitive activities on the problem so that different perspectives are essential to discuss them collaboratively (Fischer, Kollar, Mandl, & Haake, in press)
Evaluation:
•Self-evaluationofthestudents(evaluationof the procedure by the students themselves).
•Students’ evaluation by the teachers (noting down problems, ways of solving them, alternate approaches, etc.) by the students themselves in cooperation with other students, specialists, and so forth.
the communication Model
This methodology is combined with the application of the three models method of University of Maryland, University College, (UMUC), and particularlymodelΑ(IDE,1996)availableonline at http://www.umuc.edu/IDE/modeldata.html,
that is a virtual classroom composed of groups of students in two or more distant locations. The collaboration of teachers and motivators is an innovative proposal, which support effectively the whole process.
the classroom architecture Model
The aim of a distance learning methodology is to develop an interactive learning virtual space in which learning communities with common interestscan collaborate ‘face-to-face’ eachother. This is easy to manage, if we have small courses (8-10 students). But what we have to do if we a need to manage a medium or big audience? The methodology chosen is that of separating the audience into active and passive.
The active audience consists of 6-8 students who sit in a triangle on the top of which we find the teacher and the blackboard. The students of the active and passive audience alternate during the lessons, so that all the students of each class have an active role experience.
TheconceptualconvergenceofmodelΑ(IDE,
1996) with the proposed classroom architecture model forms a transitory approach of original methodology which from now on will be referred

general description
The whole project, PAIDEIA OMOGENWN (http://ediamme.edc.uoc.gr/diaspora/), aims to continue, develop, and promote Greek language and culture, to primary and secondary students of Greek origin, who live and study abroad, as well asnon-Greekspeakingstudentswhowanttolearn the Greek language and become participants of the Greek culture (Damanakis, 1987). The implementationofthespecificprogramstartedinJune
1997 and continued until December 2004. It was funded by the Greek Ministry of Education (25%) and the European Union (75%). The Ministry of EducationinGreece,withitsvariousdepartments,
supervises the program, while its implementation has been assigned to the University of Crete and more specifically to the Center of Intercultural and Migration Studies (E.DIA.M.ME.) at the Department of Education of the university with Director Professor Michali Damanaki.
One of the most important topics of the project concerns the implementation of a complete e-learning environment adopted and developed for the training for the continuous training of teachers who teach Greek as a second and foreign language through e-learning.
Based on the initial plan, learning materials were designed and developed for three courses:
1.Socialisation and Education in the Diaspora (Prof. Damanakis)
2.History and Culture in the Modern Greek (Prof. Xourdakis)
3.TopicsinModernGreekLiterature(Instructor Mitrofanis)
