The entire six-part interview series with McGraw-Hill Education's adaptive learning experts is now up on YouTube. (Full disclosure: In the months between the filming and the publication of these videos, McGraw-Hill became a client of MindWires.) Here's a good segment on teaching:
The first example Matt Haldeman gives is a math class, which is where we see adaptive learning used the most. The interesting part of it is how he describes the change in the teacher's classroom activities. This is a critical aspect this often isn't picked up when these products are used in higher ed math classes—particularly outside of developmental math.
The second example is a history class, which is a less (stereo)typical example. The focus is on class preparation. In other words, the adaptive platform helps students come to class knowing what you hope they'll know but often haven't really absorbed from a reading assignment that is meant to give them the raw materials they need for an interesting class discussion on a topic.
