Another theme (as discussed in the book Why School?) is that education systems were developed in a different era when teachers, knowledge, and information were scarce, and that is no longer the case. There are many more choices for self, expert-based, and peer-based learning, in real-time on-demand and time-shifted venues. MOOC (massive open online course) platforms like Coursera, Udacity, edX, and Class Central (a MOOC aggregator) have been growing and adding credentialing and course curation functionality. Other learning tools include podcasts, Khan Academy and YouTube videos, and Lumosity’s cognitive performance brain trainer.
A third theme is that the value chain for learning is becoming more granularly stratified. Learners are of all ages and backgrounds and have diverse educational objectives with are being supported with a variety of in-person, online, and mobile instruction tools.
