20. 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/nonProductSin gle/research_graphing.htmlhttp://education.ti.com/educationportal/sites/US/nonProductSin gle/research_graphing.html

21. 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.htmlhttp://education.ti.com/educationportal/sites/US/nonProductSingle/ research_graphing.html
