This is an update of an earlier presentation in which I outline the major elements of a personal learning environment and describe its origins in the concept of the MOOC. Some new slides describing the architecture and how to contribute to the expansion of LPSS. As well, this presentation comes the day after this workshop in Guadalajara and is informed by it. The video has the Spanish translation audio. My audio is in English (my talk starts after the intros at around the 14 or 15 minute mark, 15:17 in the video).Lecture, Aug 27, 2015.
