The new TI-Nspire™ CX CAS handheld device and companion software are designed to generate opportunities for classroom exploration and to promote greater understanding of core concepts in mathematics and science.
TI-Nspire technology has been developed through sound classroom research* which shows that "linked multiple representations are crucial in development of conceptual understanding." TI-Nspire "provides simultaneous, dynamically linked representations of graphs, equations, data and verbal explanations, such that a change in one representation is immediately reflected in the others."
In addition to the flexibility offered by TI-Nspire's menu-driven interface and built-in document structure, the CX handheld is enhanced by a backlit colour screen onto which images can be imported, helping bring concepts to life. The CAS version enables the manipulation of mathematical expressions and functions in addition to standard numerical calculations. The handheld is fitted with a rechargeable battery which can be recharged with a USB cable connected to your computer, the TI-Nspire Docking Station (for the classroom) or a wall charger. Battery life is expected to last up to two weeks under normal use.
- Different representations can share dynamically-linked data using the TI-Nspire applications: Calculator, Graphs (2D and 3D), Geometry, Lists & Spreadsheet, Data & Statistics, Notes, Questions and new Vernier DataQuest™. Users can also split the screen, enabling up to four applications to be viewed simultaneously.
- CAS (Computer Algebra System) enables manipulation of mathematical expressions and functions. Includes Symbolic Algebra, Symbolic Calculus, Symbolic Linear Differential Equations, Symbolic Equation Solver, Symbolic Units of Measure and Constants.
- Users can experience the same interface on the TI-Nspire CX CAS handheld and in the TI-Nspire CAS Software, enabling integration with existing classroom ICT infrastructure and projection systems to offer whole class teaching and personalised learning opportunities. TI-Nspire works with all major interactive whiteboard technologies.
- Import colour/black and white images from online sources or from your own digital archive and overlay graphs and other elements.
- TI-Nspire's 3D Graphing View allows you to explore surfaces by rotating them, investigate intersections of a surface with a plane and create animations using sliders to understand how changing different parameters affect 3D objects.
- Create, edit, save and share work in documents within a familiar folder structure.
- The new Vernier DataQuest™ application adds functionality for data logging allowing for the collection and analysis of real-life data in all STEM subjects.
- The USB port supports sharing – with another handheld and a computer.
- Handhelds can be integrated with a TI-Nspire CX Navigator™ system, to give an independent wireless network within the classroom.
