This is the late Peter Druckers' famous question.
I want to be remembered as someone who successfully digitized several aspects of teaching and learning, who has reduced wasteful learning of all kinds at all stages of life-long learning journey.
As Bill Gates once remarked, many people before us had tried and failed: radio, TV, CD, elearning, ecourses. A few years down the road, we may also add the recent phenomenon MOOCs(massive open online courses) to the list.
They were perhaps too ambitious.
If we aim for partial but useful solutions, focused micro-solutions, we can have a better chance.
Perhaps, we can find out many a sweet spot along the spectrum of teaching and learning. Perhaps, we just need a better business model, where incentives are better aligned.
As ever, I am optimistic. We may not come up with a Silver Bullet. Yet, small incremental improvements, when they compile, can make a real difference for all concerned: teachers. students, trainers, trainees, learners, parents and the society as a whole.
