There is no pedagogy, technology or technique that is a silver bullet or the independent variable for good teaching. Good teaching can only happen, in my opinion, when the teacher accepts that he or she must work harder than they have ever worked before, be willing to not reach all students in search of ways to empower all students. I hope one day, even if it is the last day before I retire, I can look myself in the mirror and say that I have tried to do this. No technology can make the honor of being a teacher an easier thing. Techniques, pedagogies, etc., can make what we do more efficient, but only if we first, through hours and hours of sweat, empathy and failure, work towards a system that transcends technology. This might make no sense, but I had to write it down. Ok, back to nerdy technology posts :).
