Online Collaborative Problem-Based Learning Environments: From Theory to Practice.

The  general  hypothesis guiding  our work  consists in considering  that applying  the  conceived  distributed  Problem Based  Learning  (d­PBL) requires computerized  environments developed  on  a  strong  theoretical  basis. Therefore  there  are  two  chosen  theories: the activity theory and the action theory. Our goal was to study these two theories effects on  learning  environments design, and  to see if they could  propose  fields for educational exploitation of the d­PBL method?  Our study is based on two axes: theoretical and analytical. The first axis is consecrated for a  general definition of the  PBL method  and  concluded  by proposing  a  prior evaluation  chart for the learning’s computerized environments. As for the second axis, it’s consecrated  for the analysis of the following three products, CROCODILE, SHAMSH, SCARCE.
