I feel the same way about scientific calculators. I am finding that many students are so dependent on them they cannot perform simple operaitons with positive and negative numbers. They also are weak in operations with fractions. Of course both scientific and graphing calulators can help students who do not have strong math skills and allow them to perform at higher levels but I am finding that students that have potential to perform such operations on their own do not get enough practice. In order to avoid such deficiencies, we must make sure students can graph functions, solve systems etc... on thier own before they are allowed to take exams with graphing calculators.
