Tinkering is the most natural way of learning, not only by humans but even by other thinking animals, such as monkeys. Yes, just like humans, all thinking animals tinker.
However, in recent times, all over the world educationists have rediscovered tinkering and the interest is growing fast. In some countries some from of tinkering has been introduced in the school curriculum. In UK this is called D&T, or Design and Technology. In US the inclusion of tinkering is in the form of STEM Education.
The inclusion if tinkering has happened because the skills developed because of tinkering are needed today and will be more so in the coming times. The countries that develop a culture of tinkering will acquire more and more intellectual property (such as copyrights and patents). Others will be paying through their noses to use this knowledge.
Unfortunately, as of now India is headed towards the ‘Others’ group. Even today we are paying heavily for products that should cost a fraction of what it actually does. This ranges from medicines to toys and everything in between.
Any country that is planning for the future needs to take up tinkering seriously and make learning science less serious for kids.
