I have followed Sal Kahn and the Kahn Academy since Sal first offered his TED talk. My interest was in his efforts to offer a practical way to implement an individualized mastery learning system. This recent comment from Kahn reiterates his position that individual progress systems are not a way to eliminate the role of the educator as is sometimes claimed. It is the combination of the carefully mapped series of learning tasks and the data collection system that allows the educator to identify students who are struggling and exactly where they are stuck – personalized progress and personalized help.
