What are Virtual Laboratories ?

A simulated laboratory on the local computer

A set of simulated experiments on a computer

Remote access to experiments via telepresence utilities

For research and learning

A set of real experiments in a laboratory network

Integrated remote or simulated experiments in learning systems

2. Learning & Media Didactics

Constructivistic Approach

– Authentic activities

– Explorative learning

– Learning from the current situation

– Mastering problems, dilemmas

– Presentation of multiple aspects

Medial Contemplation

– Media are not "containers" of knowledge

– Media are tools to (re)construct knowledge
