Here's my question: Does anybody know what is developmentally appropriate at each age? If math is developmental, is there a chart to describe the development somewhere? Is it really true that most adults are not developmentally ready for calculus?
I have some further questions for the science/engineering experts here.
What is the appropriate level to introduce calculators for use in classroom math and should their use be allowed without restriction from that point forward?
I ask because my kids attend different schools with different approaches (neither could use one in their elementary/middle school math courses). My daughter was required to have a graphing calculator beginning with her freshman advanced algebra (1 and � of 2) class. My son still hasn�t been allowed a calculator in math class (high school honors geometry), including for the ITBS and other standardized tests.
Which approach is better and why? Thanks.
