• Provide information and trigger actions based on
  the student model
• Adapt to students knowledge status,
  psychological mood, physical location, carriers

• Dimension (knowledge, temporal, value system)
• How to represent student model

6
Issues (II) - knowledge organization

• How to organize knowledge and activities based on
  possible status of student model
• knowledge status
• Valuation system and current position
• Schedule, time and mood
• Network situation and carrier type
• Supply knowledge and Issue activities based on
  student model

7
Issues (III)-learning society organization

• Theory background such as LPP
• How to form a learning society
• Classify the students according to their
  capability and their contributions
• Issue activities based on society position, train
  their appropriate capabilities
• Functions of each position/role in improving
  learning performance
• Form a valuation system
• Goal and motivation
• Recognized
• Self-fulfillment

8
Issues (IV) theory basis

• The theory background for the value system,
  learning motivation and knowledge endure load
• The theory background for learning support
  society, mechanism, learning model

9
Issues (V) learning model

• Learning model
• How to adapt existing model to pervasive learning
  environment
• Design new learning model for pervasive learning
  environment

10
Research questions (I)

• Will and how mobile devices sustain learning
  motivation?
• Will and how mobile devices help teachers capture
  students learning status
• Will and how mobile devices improve learning
  performance
• Will and how mobile devices carry proper
  information and activities

11
Research questions (II)

• Will always reach knowledge base improve learning
  performance
• Will always on learning support network improve
  learning performance

12
Student model

• Learning status
• ZPD, experts and guiders in ZPD
• Schedule and time ? mood, motivation
• Knowledge load level
• Network, carrier and location
• Knowledge data view
• Goal, valuation system and culture
• What kinds of classmates are recognized (student
  view)
• What kinds of students should be recognized
  (teachers view)
• In what situation will a student work hard?
• In what situation will a student abandon?
