Why Graphing Calculators? • Key Findings to Recent Research Studies: • When teachers incorporated graphing calculators into their curriculum more frequently and with greater intensity, including during less frequent math topics, student achievement was higher. • The more access students have to graphing calculators and more frequent use during instruction, the higher 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. • http://education.ti.com/educationportal/sites/US/nonProductSingle/research_graphing.html
Why Graphing Calculators? • More Key Findings to Recent Research Studies: • Strong evidence showed that student use of graphing calculators increased performance in algebra. • Students who received instruction using graphing calculators performed as well or significantly better in conceptual, problem solving and operational skill areas. • Students using calculators during instruction – but not during assessment – performed as well or better in all 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 better attitudes toward mathematics than their noncalculator-using counterparts. • http://education.ti.com/educationportal/sites/US/nonProductSingle/research_graphing.html
