The weight of a newborn's brain is 25% of that of an adult's brain, and a child's brain has developed to 90% of the adult's brain volume at the age of 6. During these 6 years, the neuron connections in the child's brain are established at the rate of 700 new connections per second, this rate stays until reaching 100% brain capacity at age 10, and thereafter the rate of growth of brain neuron connections decreases year by year.
At the age of 13-17, during this period of adolescence, in order to make its own work more efficient, the brain will screen neuron connections once, keep some commonly used neuron connections, and eliminate some less commonly used ones.
Therefore, a child's brain is in a golden period of development before entering the age of 13, and it can absorb various information widely and efficiently.
Currently the most common children's programming software such as Scratch software, although it is a set of computer program development platform developed by MIT Media Lab Lifelong Kindergarten Group, its essence is like a modular accumulation of building blocks, not code level creation.
Through building block programming such as Scratch, although basic skills such as thinking mode and attention can be trained, it misses more and deeper stimulation that children can receive during the golden period of the brain.
Children only need to be able to master the basic English instructions involved in programming to be able to touch programming at the real code level.
