First, strong summative scientifically-based research supports the effectiveness of graphing calculators and formative assessment in enhancing student achievement.
Second, long traditions of mathematics education research demonstrate the benefits of multiple representations, especially when combined with activities that engage students in doing and communicating important mathematics. TI-Nspire
handhelds provide linked multiple representations and engage students in doing and communicating mathematics via the TI-Navigator classroom network.
Third, TI-Nspire aligns with what scientists know about how people learn. Using the new document and network
capabilities, teachers should be able to increase academic learning time, scaffold mathematical argumentation, increase student participation and encourage reflection and revision.
