The emerging technology TI-Nspire CX CAS Navigator System is a handled Texas Instrument (TI) product for math, science, chemistry, physics, and algebraic precision, all in one that rekindles the impact of the 3000 BC abacus. It retrieves the 1950s slide rule , the 1980s scientific calculators, and the TI scientific calculators. Figure 1 displays the visual image of the emerging and obsolete technologies. The TI-technology goes through a predictable, non-linear process in which it becomes exponentially more powerful over time, according to Moore Law (Grifantini, 2009; Laureate Education, 2009). The TI-Nspire CX CAS Navigator System’s affect regenerates the use of desktop graphical software, scientific calculator, and projector on white screen, in mathematical computations, and follows the McLuhan's tetrad model (Thornburg, 2008b). The new technology, the evolution of the obsolete scientific calculator, is a rhyme of history (Laureate Education, 2009) of the counting principle concepts. Rhymes of history and evolutionary technology are two components of Dr. Thornburg’s six causal forces of emerging technologies (Laureate Education, 2009), as he pondered over the origin, evolvement, and reach in the mainstream of new technologies (Thornburg, 2008a). The TI-Nspire CX CAS Navigator System is an evolutionary technology of the mentioned obsolete technologies, and depicts the two mentioned complementary forces.
The TI-Nspire CX CAS Navigator System exemplifies Kelly’s (2007) analogical concepts of embodiment, restructuring, and codependency on the web as examples of the assonances of history. As the web acts like the brain (Kelly, 2007), the TI-Nspire CX CAS Navigator System embodies humans’ computational capabilities, as an extension of human senses. Individuals (scholars, innovators, engineers, and programmers) program calculators that become an extension of humans (Kelly, 2007). Although the programed calculators might handle complex computations faster than humans, they might not function without humans. Humans depend on the programmed calculators for quick, fast, and easy computations. Evidently, the graphing calculator and humans become codependent. The restructuring takes place in linking individuals to created pages, across documents and multiple representations that allow students to interact directly with mathematical concepts (Ulus, 2013) via the use of visualization and animation tools, in manipulating one form that simultaneously changes all the others. Kelly’s (2009) video rekindled the researcher’s mental and pen and paper, mathematical computations in in elementary school, and slide rule and scientific computations in high school.
Although some educators might believe that dependence on graphing calculators might cause students to lose their mental computation ability, standardized testing organizations have approved the TI-Nspire CX CAS handheld for SAT, PSAT, national merit scholarship-qualifying test (NMSQT), AP, and Praxis high-stakes exams (College Board, 2014). The researcher awaits for the TI-pocket-sized and wireless mini device with a full functionality of tablets PC, as computational device, in higher mathematics, engineering, science, chemistry, and physics.
