Can I use the TI-Nspire CAS handheld and TI-89 Titanium graphing calculator in my classroom simultaneously?
Although both models feature CAS (Computer Algebra System), their functionality and user interface differences would likely affect the approaches used in exploring some concepts. This could also create operational confusion among students. In addition, the TI-Nspire CAS handheld offers new and unique pedagogical benefits that the TI-89 Titanium does not.
