Why Graphing Calculators?
• When teachers incorporated graphing calculators into their curriculum more frequently and with greater intensity, including during less frequent math topics, •
student achievement was higher
. and more frequent use during instruction, the
1 their end-of-course test scores
. • Increased use of graphing calculators during instruction resulted in
higher test scores even when students did not use graphing calculators during testing

Why Graphing Calculators?
• More Key Findings to Recent Research Studies: • Strong evidence showed that student use of graphing calculators calculators
areas
• .
increased performance in algebra
. • Students who received instruction using graphing
performed as well or significantly better in conceptual, problem solving and operational skill
• Students using calculators during instruction – but
during assessment counterparts
.
–
five math skill areas
. This key finding also indicates that student math skills did not suffer even without calculator use specifically during assessment. • Students using calculators had
mathematics than their noncalculator-using
