Hi folks, how are you?
As you all know, calculator effects on individual people range from positive through neutral to negative and could either increase or decrease the validity of a person as a measure of mathematical reasoning skills.
However, there are different views about it. My schoolteacher, for instance, said we may never afford to use it till the fourth year, when sines and cosines suddently spring up in trigonometry; but she assured us we needn't to use it for the whole third year.
On the other way round, a different maths teacher I know is said to be unconcerned about this kind of things, perhaps he's more focused on other skills, such as what you really need to be conscious of or even what you are really requested to be acquainted with.
So my question is referred to all people, teachers or not, and would be: should we allow students to use calculators during lessons, tests... or whatever you want, or you think that the prohibition is made only in order to maintain our brain trained and ... Would it have effects?
