When we talk about learning/education as developing the human capital and potential, sometimes, it is odd to find that best invention came from need.
From BBC news, after years of neglect and civil war, the railways in Cambodian has only one passenger service per week.
So people in the north west of the country, near Cambodia's second city of Battambang, have taken matters into their own hands.
They have created their own rail service using little more than pieces of bamboo. The locals call the vehicles "noris", or "lorries", but overseas visitors know them as "bamboo trains".
If we are to learn anything from the story, we should design our courses so that students have to solve real life problem as a goal.
