Abstract/Introduction

• The paper present a model of learning as a social
  process
• Individual minds in relation to socio-cultural
• Framework for the design of CSCL-SW (KBE)
• 5 theories of learning (Koschmann)
• The paper incorporating insights from these
  theories/philosophies
• Multiple phases constitute a cycle gt
  increasingly complex questions to be posed

Opportunities for Computer Support

The Idea of a Computer System to Support the
Knowledge-Building Process(1)

• A KBE should
• go beyond a single-purpose system
• retain a record of the knowledge that was built
  up
• And it should therefore probably be
• built on asynchronous, persistent collaborative
  technologies and be deployed on the Internet as a
  Web-based environment

7
The Idea of a Computer System to Support the
Knowledge-Building Process(2)

• A KBE should
• Support several lifecycle phases
• Help people express their beliefs, discuss them
  with others, negotiate shared understandings
  
• Provide facilities like searching, browsing,
  filtering
• Significant difficulties but their potential
  advantages seem extraordinary!

8
Conclusion

• The process model of knowledge-building
  presented in this paper provides a conceptual
  framework for the design, use and assessment of
  such systems
• KBEs have the potential to provide
  computationally-supported communication media to
  facilitate this process that forms a centerpiece
  of the learning sciences.

Miao et al. (2005) CSCL Scripts Modeling
Features and Potential Use

• Introduction
• Part one
• Investigating the capacity of IMS LD for
  formalizing Collaborative Learning Scripts
• An approach to formalize CSCL Scripts
• CSCL script authoring tools
• Part two
• Potential uses and system support of CSCL scripts
• Conclusions and future work

10
Introduction(1)

• Collaboration script is a set of instructions
  specifying how the group members should interact
  and collaborate to solve a problem. ODonnell
  Dansereau(1992)
• Internal or external representations
• A CSCL-script is a computational representation
  of a collaborative script
• A general modelling language for formalising
  collaboration scripts is missing.
• No tool for CSCL practitioners to create, reuse,
  integrate, and customize CSCL scripts.

11
Introduction(2)

• Existing learning process modelling language
  IMS-LD provides insufficient support to model
  group-based, synchronous collaborative learning
  activities.
• Some attempts have been done to extend IMS-LD,
  but still no good solutions.
• The aim for the research work presented in this
  paper is to develop a scripting language for
  formalising CSCL scripts and exploring their
  potential types of usage and system support
  possibilities

12
Investigating the capacity of IMS LD for
formalizing Collaborative Learning Scripts

• Maze script, strategies how to escape
• Major difficulties and challenges in modelling
• Groups
• Artefacts
• Dynamic features
• Complicated control flow
• Varied forms of social interaction

13
An approach to formalize CSCL ScriptsCSCL
Scripting language
14
An approach to formalize CSCL ScriptsSolution

• Explicitly introducing groups
• Explicitly introducing artefacts
• Extending actions and expressions
• Introducing transitions and routing activities
• Using activity-centred methods to assign roles

15
CSCL script authoring tools
16
Potential uses and system support of CSCL scripts

• System as Editor/Viewer
• Syntactical mapping to a visual/conceptual
  representation
• Presentation of models in multiple perspective
• Procedural/Temporal
• Artefacts
• Roles
• Individual/Group
• Model-based prediction
• Simulation
• Static configuration of the learning environment
• Monitoring of the learning flow
• Model-based scaffolding

17
Conclusions and future work

• Stated five major limitations in IMS LD when
  formalising CSCL scripts
• Suggested a scripting language for CSCL based on
  this, where these limitations are solved
• Discussed potential usages of CSCL scripts and
  possibilities of system support
• Developed two script authoring tools, based on
  the CSCL scripting language
• Currently focusing on testing the modelling
  capacity, real experiments will be conducted
• Will develop an integrated environment later on.
