In conclusion, PLE, PLN, Do it yourself and online education via various means like MOOC have their own merits and limitations, and it would be important to question the assumptions behind each model of education and learning, in order to match the needs and expectations of BOTH educators and learners.
Learning in a landscape of practice or networks of practice is both challenging and rewarding, though, each promise comes also with basic questions: Is this sort of learning valued by the learners? Is it an effective way of learning? How? and Why? Research and continuous exploration through experimentation and application would likely provide the answer to the question of: What is knowledge? What is learning? And how does it occur at this digital age.
