Competences Competences motivated by PLEsmotivated by PLEs

Planning competence refers to those skills, abilities, habits, attitudes, and knowledge that fix how goals, schedules, and paths are set.

Reflection is creative sense making of the past and enables planning.

Monitoring refers to how progress control is performed.

Last but not least, the pair acting and interacting group social & collaboration and information & tool competences.

Qualitative Interviews with stakeholders (learners, facilitators, learning designers, researchers): 15 persons in 5 sessions (each 40 min to 1 hour) #4

Users involve in use-cases.

Each case deploys widgets in support of the given task.

Widgets use infrastructure services & data (from within the PLE container or from the Web 2.0).

A directory serves the management and deployment of the portfolio.

Interoperability standards secure the flexible recombination of widgets, services, and data.

PLE Implementation PLE Implementation StrategiesStrategies• Coordinated Use

– e.g. with the help of browser bookmarks to involved web apps

• Simple Connectors for Data Exchange and service interoperability

• Abstracted Connectors that form Conduits– e.g. those supported by the social browser Flock – e.g. by the service-oriented PLE Plex
