Question

请帮我看下有没有语法错误谢谢

For the first number that I have seen in the second paragraph, “$24000” is extremely expensive for those parents who sent their kids to a digital detox program for a month. They could have prevented this by reducing the use of cell phones.
The number in the third paragraph which is “80%” shows that most of U.S. school districts encourage children to use the electronic production in the class, but students have to use those tablets which are provided by the school. Obviously, this stipulation imposes restriction students on playing computer games and it obtains the supports from so many schools.
“12%” actually shows us the advantage of playing some puzzle games ,those students who are interested in playing puzzle games usually have a better scores in the logic tests.
“10%”, “20%”, those two numbers show that we can only remember few data if we use the conventional methods to recite or to memorize them ,which is the biggest problem of the non-digital teaching.
“50%”from the demonstration actually made a great progress ,however, compare with the “90%” which is from the virtual demonstration, we can obviously discover the disadvantage of the normal demonstration: students can be much more efficient by using the electronic production.
