I agree with the statement by Martha about graphing calculators. In the =
years that I worked with teachers and now my own students in the community =
college I have seen many students take a rule-based approach to learning. =
The students will develop a template they follow blindly whether it is =
with a calculator, a computer, or paper and pencil. Unfortunately the =
templates won't work in the real world very well. The sad thing is that =
many teachers also follow the templates they learned as students and carry =
these into their teaching so many students are handed down a cook book =
type of math.=20

It is much harder to get students to break away from their templates ( or =
bag of rules) and to build connections and understanding about what they =
are learning. Anyone who begans to change their approach to instruction =
to one of building connections and understanding will go through a great =
deal of conflict with the "system" and the way rule learning is enculturate=
d in to the classroom. Helping students to deal with their conflicts about =
value of rule learning is a big part of the job. They will often fall back =
into the old pattern when frustrated. But in the long run if students are =
taught and expected to build connections and understanding when they work =
with any piece of technology students will remember more, will build new =
understandings faster, and will become autonomous in their learning of =
math . =20

Also please understand, I am not saying there is no place for rules in =
learning math. They are necessary. But if you are using technology or not =
rules must be build by the students themselves in a meaningful way and =
connected if they are to be useful in thier lives.

Question: If someone can mindlessly perform a mathematical behavior, has =
that person truely the learned the math involved?
