Evolution and development of a PLE at the University of León

The present paper has been developed in different classrooms since 2006 in order to train students for Mathematics and Teaching at the Faculty of Education (University of León). The students are committed to a participatory and collaborative work, and they have been guided by ongoing assessment based training for more than four years. In this time they have been implementing various web-based Tools in order to reach what is today called a personal learning environment (PLE). The protagonists of the learning / teaching process are the students themselves. As teachers in training, they must demonstrate a range of skills and professional development skills in their jobs and also the skills of information retrieval and critical thinking through this custom platform. They have conducted surveys and interviews in order to measure the the necessary skills? to manage this connective environment network. In this article, we show a preliminary study of external influences needed to develop this environment. In a second phase we can see the evolution of performance under this personal learning environment and its objectives: the ability to self-manage their own learning of Mathematics teaching and the problems that they have arisen at the University because of being an isolated experience and a lack of commitment to self-organized and negotiated learning.
