A methodological and physical instrumentation to support experimentation in telE-learning

This article is an attempt to promote R&D methodology that is actionoriented in order to improve the development of tele-learning environments and software artefacts fully adapted to learning activities. First we start by presenting an overview of the two main phases of action-oriented research, stressing the importance of control methods. Secondly, we describe difficulties in applying these methods and, finally, we introduce the LORIT, a recent initiative intended to support instrumentation in tele-learning research.
