Calculators with computer algebra systems (CAS) are powerful tools when working with equations and algebraic expressions in mathematics. When calculators are allowed to be used during assessments but are not available or provided to every student, they may cause bias. The CAS calculators may also have an impact on the trustworthiness of results.…

The increasing use of microcomputers and hand-held calculators has implications for mathematics and science instruction, achievement testing, and educational research. The potential effects of these technologies on curricula involve both content and delivery. In mathematics instruction, the focus may shift from manipulative to higher order skills.…
