Context


In this experiment, we are studying
 the ubiquitous computing possibilities
 to use contextualized forums in order
 to improve just in time professional
 training to business process of
 100 000 people.

         The p-LearNet project



This experiment belong to the P-
 LearNet project.
  Participatipatory Design.
  Scenarios of use validated.
  Project organised in 3 major stages,
  iterative definition and validation of
  the training supports and prototypes.
  Actually : 1st stage, experimental
  phase.                               3
          Forums: a paradoxal situation
Forums are less adapted to:
  • The construction of a common base of
    knowledge [Henri, Peraya, et al., 2007]
  • Support the life of a community of
    practice, [Clark,Brennan,1991]
  • Support the communication without
    ambiguity, [Dennis, Valacich, 1999]
  • A pedagogical use, [Henri, Lundgren-
    Cayrol, 2001]

         Contextualised Forums [georges
         2005]


Complete forums by adding mobile
 devices' captured indications (GPS,
 pictures, videos).
Link the contributions to the courses.
Resolution of the ambiguities
 associated to the written
 communication.


                                          10
Constraints of Mobile Devices


(1) small sized screens
(2) difficulty to write long text
 messages
(3) network actually less reliable and
 slow
(4) memory for storage and power
 aren’t very high

                                          11
Constraints for Users



(1) not enough time to read all the
 propositions
(2) answers are given often after
 reading a section and its associated
 mini-forum : Will the user have the
 time in the action to propose a
 solution to a problem he already
 resolved ?

                 First learned lessons of the
                 project(after 14 months)‫‏‬

 First stage:
   • Validation of the first scenarios
   • Search for technical constraint
   • Primary tests
 A common learning of the research innovation and
  developpement methods in the usage
 Principal concepts
   • Training through the professional activity
   • Allow the employees to contribute to the production of
     pedagogical resources (knowledge management)‫‏‬
