Αξιοποίηση ενός εκπαιδευτικού προγράμματος βασισμένου στην PBL σε περιβάλλον CSCL : αξιοποίηση της μεθόδου PBL σε ένα τεχνολογικά υποστηριζόμενο περιβάλλον μάθησης για τη διδασκαλία της νεοελληνικής γλώσσας στη δευτεροβάθμια εκπαίδευση

Research has shown that the acquisition of students’ collaboration and language skills is more effective through web-based instruction and computer-meditated communication. Several researchers support that in this way, learners connect to a larger extent and in a better way with authentic language learning environments and become more experienced in collaborative learning and social interaction which are associated with the improvement of language learning skills. Taking all the above into account, the main aim of this research is the design and implementation of an educational scenario, which is based on the principles of a theoretical model in a Computer Supported Collaborative Learning (CSCL) environment so as, through a series of sessions, students to work in groups and to improve their collaborative and language learning skills. To be more specific, the aim of this master thesis is to evaluate to what extent the theory of PBL (Problem Based Learning) combined with the Jigsaw II collaborative strategy, while implemented in an educational scenario, can improve, in a Computer Supported Collaborative Learning (CSCL) environment, the collaboration and language learning skills of high school students in the discipline of Language. The proposed educational environment is incorporated in an open-source online Learning Management System (Moodle). In this environment, students interact and collaborate in groups. As a result, the master thesis at hand contributes to other researchers’ proposals for the implementation of PBL in the field of language learning. This master thesis’ innovation is the attempt to find out in which way PBL could be implemented in language teaching and specifically in teaching Greek language for high school students in a Computer Supported Collaborative Learning (CSCL) environment in order to enhance and improve their collaboration and language learning skills. More specifically, the subjects of the study (20 high school students) collaborated in Moodle through a PBL scenario in order to enhance their collaboration as well as their learning skills in Modern Greek Language. In particular, the PBL scenario, based on the “seven –step” PBL model and on Jigsaw II collaborative strategy, was implemented through a series of 6 Sessions (steps of the procedure) in order students to solve the ‘ill-structured” problem set by the design of the educational scenario while working in groups (initial groups, expert groups, Jigsaw groups). Our research was based on quantitative and qualitative data analysis as shown in the context of the chat, forum and wiki log files on Moodle. The analysis has shown that students can improve skills through a properly designed on –line learning environment in order to acquire better learning outcomes. The master thesis at hand contributes to the research of the implementation of PBL in the effective teaching of language lessons and in the development of collaboration and language learning high school students’ skills.
