The Proactive E-Learning Courses (PEC) for mobile environments is mainly a concept with any prototypical implementations of their components. This concept was developed by Dr. Steffen Mencke (see Steffen Mencke: Proactive Ontology-Based Content Provision in the Context of e-Learning, University of Magdeburg, 2008). The principles are the application of the e-learning standards like SCORM (Sharable Content Object Reference Model) and IMS LIP (Instructional Management System Learner Information Package). The application of the SCORM using the principles

(P1) The necessity of lifelong learning requiring a disciplinary continuous motivation for course participation

(P2) The missing information about new conditions of (certified) qualification in special work areas

(P3) The necessity of managing many (personal) processes where qualification/learning is only one of these processes that could sometimes be placed in the “background”

(P4) The missing information about new courses based on new research results in a special area of professionals

(P5) supporting the students in order to manage the course scheduling more efficiently as a “background planner”.

(P6) addressing more students/learners for the lifelong learning in a postgraduate kind of study.

is shown in the following figure.

The concept motivates an agent-based system approach using the criterias

(A1) storing different learner profiles in order to adapt the new/extended e-learning courses to the learners requirements

(A2) using internal or external resources for autonomous course extensions and adaptations

(A3) storing the learner context profiles in order to react to the current learner situations in proactive manner

That leads to the following general architecture.

Furthermore, any criterias of context awareness and mobility are used as following

(C1) Computing context: such as network connectivity, communication costs and bandwidth, resources as computer infrastructures (especially technological context)

(C2) User context: such as user’s profile location, people nearby and current social situation (especially organizational and action context)

(C3) Physical context: such as lighting, noise levels, traffic conditions and temperature (especially geographical and time context)

(C5) Automatic contextual reconfiguration: A system level technique that creates an automatic binding an available resource based on the current context.

(C6) Contextual command applications: Executable services made available according to the user’s context or whose execution is modified based on the user’s context.

(C7) Context-triggered actions: These are applications that automatically understand the context they are in and execute service automatically when the right combination of context exists.

(M1) It is necessary to choose the mobile technologies which should be supported in the e-leaning courses (as protocols (TCP/IP, WAP, HTTP, etc.), communication networks (GSM, HSCSD, GPRS, UMTS etc.) and platforms (Palm OS, Windows CE etc.).

(M2) The course contents should be made compatible with different chosen mobile technologies (HTML, WML etc.).

(M3) Context-related situation of organizational and policy standards must be taken into consideration.

Considering the IMS LIP standard, we can establish the foloowing involvements and component characteristics for PEC based e-learning applications.

Finally, the PEC approach motivates the following infrastructure for mobile oriented proactive e-learning applications.
