Pre-school children are on iPhones and iPads and probably would figure texting on their own.
So they come to school and put a pencil in their hands. ?
That IS insane.
Think about the way we learned to speak and listen. Word by word and we spoke because we wanted to and join others. If you take away the pencil, children can learn to read and write the way they learned to speak and listen. Teach them the keyboard and then words. Let them send email to a child in Nepal. They will learn to read and write while you are teaching them about Nepal. And for homework they have to find Nepal on Google earth and the countries near it.
In the 19th Century arithmetic was the doorway to higher math. Now we do not need this antique lower math.
We teach mathematics on a spreadsheet and calculation separately with an emphasis on estimation.
Students are evaluated on what they have accomplished, not some score on a test.
That is my model for the 21st Century and I expect to start shortly in Africa and Asia
You could even have a program called Handwriting Arts.
