Texas Instruments TI-NSpire Math and Science Handheld Graphing Calculator
Product Description The TI-Nspire handheld comes with a snap-in TI-84 Plus Keypad that provides the same keystrokes as TI-83 Plus, TI-84 Plus and TI-84 Plus Silver Edition graphing calculators. Whether handhelds are provided by your school or your students bring in personally-owned units, this side-by-side compatibility between TI-Nspire handhelds and existing TI graphing calculators delivers a comfortable transition to TI-Nspire technology. Inclueds USB cable for software and file downloads. Product Description The TI-NSPIRE combines interactive graphing capabilities and innovative computer features into one convenient learning handheld, perfect for Algebra 1 & 2, Geometry, Pre-Calculus, Statistics, Chemistry and more. This handheld is compatible with other TI calculator models and permitted for use on the SAT, ACT and AP exams. Dynamic linking instantly reflects changes to one representation in real time to other representations of the same problem Create and save problem-solving steps as electronic documents and pages USB cable for software and file downloads included 20MB ROM/16MB RAM Power Supply - 4 AAA batteries (included) Reader Reviews I began using Texas Instruments' graphing calculators with the TI-83. In addition, I've used the TI-81 and TI-82. I've seen the calculators improve through the TI-83+, the silver edition, and the TI-84+ and its flavors. They were all improvements and refinements, but not revolutionary. My classroom uses them all and, except for the TI-81 and 82, it's not a problem. The TI-Nspire is truly a new design. Texas Instruments has implemented a true file system, a great display, "pretty print", and a nice, organized interface for solving problems. Even better, the student can save the problems, link graphical, numerical, and spreadsheet analysis, and even add notes. The ambitious teacher could even create calculator-based problems that utilize all these features and load them on student calculators. I'm interested to see if I can get a few of these for next year. Then I can talk about how well it works out in a classroom. There are some distinct drawbacks. The greatest is the keyboard. I like the letters. For quick notes, they're fine. Unfortunately, there isn't quite enough room for my fingers. I keep bumping letter keys. Just a tiny bit extra space would be great! In addition, some functions, such as editing a solution, are not obvious. Nor is moving files around obvious. This calculator is compatible with the CBL with the TI-84 keyboard installed, but I hope to see this functionality added with its regular keyboard. I also hope that TI soon releases software so that I can use this calculator with my Mac or even my Linux machine. Overall, I like the machine, but it does need some polish. Edit (4-29-08): I recently ran into an irritation. While "playing" I decided to have the calculator find a limit of a function. The calculator informed me that I needed to have a CAS. It really bothers me that TI would include features on this calculator that it cannot actually perform. Comment (1) | | (Report this)
