TED speech: use a computer to teach your children real mathematics: math! = Calculating -- Feelings

I attended a TED speech this morning: I used computers to teach my children real mathematics. The speaker first proposed that students learn mathematics more and more boring, while mathematicians feel that they know and understand the mathematical knowledge and their limitations. Then he proposed the disadvantages of mathematics teaching: modern mathematics teaching still teaches children how to calculate by hand, while ignoring the cultivation of abilities that are more important than computing to solve practical problems. Math! = Calculating ). Computing is only a small part of mathematics. In addition, manual computing can be replaced by computers. Then he entered the climax of his speech: he believes that the current mathematics teaching and
The exam should allow and promote the use of computer and computer programming (not just calculators, but calculators are dummies compared to computers ). In this way, you don't have to spend a lot of time doing what computers can do, but focus on the more important research to solve practical mathematical problems. This will bring about a huge revolution in Mathematics Teaching: we may be able to get in touch with the limit and calculus concepts learned by high school when studying and calculating the circumference and area of a circle in elementary school. Many courses are no longer based on the difficulty of computing, but on the difficulty of understanding, because a lot of computing work can be done by computers. Think about the mathematics we study in junior, senior, and university. Most of the time is being practiced and calculated manually: the first equation, the second equation, and the buoyancy force are equal ???, The current is arranged and combined through the voltage after several conductors, the coordinate of the hyperbolic curve and the intersection of the circular (the computer calculates the factorial of n very quickly) probability, especially the long string of physical formulas about electromagnetism. We have spent a lot of time on computing, and have neglected the application of mathematical modeling and mathematics in practical problems. No wonder the difficulty of all application-related questions is a little high, but it is not difficult. To calculate the profit of bank deposits .. . The calculus of a university is also a few common models, but we can't spend more time understanding calculus, applying calculus, but computing calculus. Computing can be replaced by computers that are 10 million times more efficient than humans. Fortunately, I saw this video. Fortunately, I learned computer science. I can learn more mathematical ideas and learn more about the essence of mathematics, but I don't have to calculate the values by computer.
