TAILIEUCHUNG - Lecture Notes in Computer Science- P86

Lecture Notes in Computer Science- P86:This year, we received about 170 submissions to ICWL 2008. There were a total of 52 full papers, representing an acceptance rate of about 30%, plus one invited paper accepted for inclusion in this LNCS proceedings. The authors of these accepted papers | 414 Y. Wang and K. Li In the situations above we proposed a theme-based online collaborative learning model which integrated the online thematic and collaborative learning. Then guided by the model we developed an online learning system and performed a case study which can intuitively analyze the varying tendency of the participation in five stages of group lifecycle in some online collaborative learning activities such as collecting and sharing learning resources communications in online virtual forums and so on. Finally we drew some conclusions and discussed some future works about the system. 2 System Design An Online Theme-Based Collaborative Learning Model OTBCL Model Based on the definitions and instruction design of online thematic and collaborative learning we proposed an online thematic collaborative learning model named OTBCL model acronym of Online Theme-Based Collaborative Learning Fig. 1 . The model is composed of three circles outside circle middle circle and inner circle. In the outside circle there are eight explicit learning activities which are typical and necessary steps to carry out an online thematic collaborative learning. In the middle circle it is learning portfolios that serve as tools scaffolding introspection of learners and evaluation of teachers. The learning portfolios are represented by some participatory indicators which are educed by learners actions tracked and logged in outer circle. Inner circle includes the processes of reasoning and thinking in the mind of learners plan action and reflection. In the overview of the model the learning portfolios in the middle circle which serve as social media and technology tools support and facilitate the process between interpersonal socialization in the outer circle and mental internalization in the inner circle.
