What did children need to learn how to do in the earliest time?

W: Last week; we discussed how people learnt in the earliest time. Today I would like to continue our discussion about education, but we’ll focus on development of our schooling. Mr.Johnson, what’s your opinion about the tendency in development of schooling education.
M: Let’s look back in history to an early way of life. At one time, children didn’t have to learn any more than how to cope with their physical environment. They had to learn to be careful around moving objects, to draw back when they got too close to something dangerous. They didn’t need a special school to learn these things other than a school of experience. Nor was a school necessary for them to learn how to survive ,because their parents taught them all they needed to know about how to hunt and to grow crops. But the society became more complex, people depended more on others who were living far away. So it became important for children to learn to read and write. When money was created, they needed to learn to count and calculate. Children had to know these things in order to survive in this new, expand ed environment. Because such skills could not be learned simply through first-hand experience, schools became necessary. So the children could be taught what we now called the three R’s: reading, writing and arithmetic.
W: Thank you Mr. Johnson. You give us a wonderful idea about the development of our formal education.
