The integration of all these possibilities on the web in a Personal Learning Environment (PLE) in a way that the learners can select, individualize and customize the learning resources and services according to their needs and interests can support learners and teachers and enhance learning in general. For this purpose Graz University of Technology has developed a PLE that bases on mashup of widgets. In this paper the PLE architecture in general is described. The widget-based approach that follows the W3C standard is pointed out and the first widget prototypes as well as some student projects for widget development are illustrated.
