In this paper, we propose to include adaptation, in particular to the laearning styles, to traditional e-learning systems in order to get a new application which adapts its contents to the user instead of being the user who adapts his habits to what the system requires. We also present the Intuitive-use Oriented Webtool for the creation of Adapted contents (in an e-learning environment), a.k.a. IOWA, an application which allows teachers to create adapted contents which will be showed later to students depending on the style they belong to.
