McGraw-Hill’s adaptive learning suite is now more flexible for teachers, allowing use with any textbook or open source eBook.
Here is a short video tour of "LearnSmart":
Essentially, adaptive learning…
"…makes content dynamic and interactive, placing the student at the center of his or her individual learning experience. The [digital learning] platform monitors how the student interacts with the system and learns, leveraging the enormous quantities of data generated by a student’s online interactions with ordinary (textbook-like) and extraordinary (game- and social-media-like) content, with teachers and peers, and with the system itself. It assesses not only what a student knows now, but also determines what activities and interactions, developed by which providers, delivered in what sequence and medium, most greatly increase the possibility of that student’s academic success."
