In my investigations, students needed guidance by teachers to break education (math in my case) into palatable morsels, with A logical sequence. The idea of factory-line learning is outdated, but the model of groups learning from an expert is going to be hard to break.
The evolution of the revolution will take a while, and ITM has been doing a great job of showing glimpses of where or how it can lead - but doesn't have to lead.
We don't need to go back to apprenticeships for learning, but anything that can nurture a student's passion for something and the learning that follows... the role of the educator is to guide the learner to and through the information required.
But what about the learner who has no passion? I like the sports/fitness/health analogy. Not every kid has a sport that he/she is passionate about, and even exercise may be low in importance. But if the person doesn't have the basic muscles, coordination, balance and stamina, those passions may never have the opportunity to develop.
Throwing this back into education, we see the need for addressing different levels of interest and student goals. While flipping offers chances for all students to build the necessary skills, the more important thing about flipping/inversion/perversion is offering the motivated student the chance to pursue his/her interests under teacher guidance, and yet allowing the unmotivated student the opportunity to follow a manageable pace that can build the foundation for when such interests may come along. And as the "shift happens" video describes, those passions may not even exist yet.
No, flipping is not the final solution, but it sure does allow the opportunity for some change to occur in this outdated education model. And unless some huge problems rear their ugly heads revealing that "flipping is detrimental to learning", we've got to Enjoy the opportunity now and see where it takes us.
Oh yeah, and along the way, let's count the number of problems with "assembly line education" that we don't have to worry about so much anymore.
