These systems use the science of big data analytics as developed by Google, Amazon, Facebook. In this sense the adapted learning is a giant recommendation engine. It’s similar to the way that Google collects data based on user search patterns. Adapted learning detects patterns of student successes and failures with the course material and chooses the content accordingly. It adapts the sequencing of the content and individualizes the pace of learning, keeping students in the zone of proximal development with content that is neither too easy nor too hard (Upbin, 2011).
