Learning at Workplace
• Features
– Enhance business performance and quality
• Focused on working activities: situated Learning
– Acquire new knowledge, meta-knowledge and skills
– Reflect on business processes

In Proceedings of mLearn2010 9
Proposal
• A Mixed Learning Strategy based on– A Situation-based Learning Strategy
– An Activity-based Learning Strategy
• To ensure learning in context, across contexts and seamless learning
20-22/10/2010
Situation-Based Strategy

The Process
In Proceedings of mLearn2010 12
Seamless Learning at Two Levels
• At learning object level
– New situation : the system enables an employee to continue his/her activity with the same entity or an equivalent one.
• At domain concept level
– New situation : an employee may go on to acquire the same knowledge and / or concepts.

In Proceedings of mLearn2010 13
Advantages/Drawbacks
• Advantages– Push and pull modes
• Employee oriented and system oriented learning according to the current situation
– Recommendations
• Drawbacks– Do not guarantee learning consistency– Unknown employee intention

In Proceedings of mLearn2010 17
Seamless Learning
• A structured activity organises and coordinates a set of sub activities
– Meaning, consistency, etc.
• From situation history, the states of pairs (Task, Method) (which have been interrupted) are used to provide the relevant ones
• For structured activities, a competence model is used to provide the next relevant way to achieve a task
20-22/10/2010
In Proceedings of mLearn2010 18
Advantages / Drawbacks
Advantages
Employee intention is well known
Precise situations
Global consistency of activities and sub-activities
Drawbacks
All activities cannot be structured
All activities cannot be pre-defined
As a pre-defined activity is well known selection criteria are more constrained
Sometimes, no activity at all is proposed

Mixed Strategy

In Proceedings of mLearn2010 20
A Mixed Strategy
• Situation-based and Activity-based Strategies are interweaved
– To « suppress » some drawbacks
– To deal with more situations and activities
• Pre-defined or not
– To enhance seamless learning and working

Situation-based vs Activity-based
• Activity-based Situation-based
– No activity proposed, too many constraints
– Recommendation of entities (automatically)
• Situation-based is less constrained
• Situation-based Activity-based
– Manually in push and pull mode
