Resource-Based Learning


Challenges in Resource-Based Learning

Web Resources are not created for learning purposes

No existing pedagogical support There is no teacher or tutor to guide the learner There is no structured learning process There is no specifically prepared learning material

Entire Learning Process is self-directed The learner has to find relevant web resources Learners have to manage different tasks in addition to learning


Requirements for Resource-Based Learning

Support for all Resource-based learning tasks in one platform

Identify information need Plan and reflect on learning process Search for relevant web resources Annotate, tag and organize resources Use resources e.g. to prepare a

presentation Share and distribute resources and

results to others

Pedagogical Concept

Activities organize tasks Structure hierarchically

Create sub-activities and super-activities Attach Resources to Activities Describe and Attach Experiences to Activities

Asking questions Discussing issues with others

Create and Attach Result Document to Activity


Evaluation and Implementation

Evaluation of pedagogical concept(One-day workshop with 32 participants)

Formulation of activities was helpful Reflection process was found important Need for more support when structuring activities
