TI-Nspire Todd Lindbloom CSLO Model Schools What is the TI-Nspire? • TI-Nspire technology provides the flexibility and versatility to meet different classroom and curriculum needs. • Educators and students have the option to use handhelds or computer software, or both, at school and at home – they are also permitted on college entrance and advanced placement exams. • The TI-Nspire handheld comes with the interchangeable TI- 84 Plus Keypad* that provides compatibility with the TI-83 Plus and TI-84 Plus families of graphing calculators. By inserting the TI-84 Plus Keypad, educators and students can continue using the TI-Nspire handheld alongside TI-83 Plus, TI-84 Plus and TI- 84 Plus Silver Edition graphing calculator models. • The TI-Nspire handheld is priced comparably to the TI-84 Plus Silver Edition graphing calculator. TI-Nspire CAS (Computer Algebra System) • The TI-Nspire CAS handheld and computer software share the same functionality and user interface features of TI-Nspire technology – plus a built-in Computer Algebra System. CAS adds an interactive dimension to exploring symbolic algebra and symbolic calculus, in addition to standard numeric calculations. • The TI-Nspire CAS handheld is priced comparably to the TI-89 Titanium graphing calculator. Multiple Representations • With TI-Nspire™ and TI-Nspire CAS technology, educators and students can see multiple representations of a problem – algebraic, graphical, geometric, numeric and written – on a single screen. Explore individual representations, one at a time, or as many as four all on the same screen. • Choose different split-screen options. Using a drop-down menu, select the number of representations and their arrangement on screen. • Representations can be dynamically linked. This means that changes made to one representation of a problem are automatically reflected in other representations of the same problem – instantly, in real time, on the same screen. The dynamic linking of multiple representations provides real-time, interactive feedback so students can try different problem- solving techniques. Multiple Representations • CALCULATOR supporting algebraic representations Perform computations. Enter and view expressions, equations and formulas exactly as they appear in math textbooks. Quickly and easily select the proper syntax, symbols and variables from a template that supports standard mathematical notation. Scroll through previous entries to explore outcomes and patterns. • GRAPHS & GEOMETRY supporting graphical and geometric representations Graph equations, expressions and other functions. Then make changes to variables to see how the values in dynamically linked tables and equations will also change, in real time. Add labels, rename the axes and include text on the graph's coordinate plane. Construct and explore geometric figures interactively and create animations. Integrate graphing and geometry on the same screen to help reveal connections between concepts in algebra and geometry. • LISTS & SPREADSHEET supporting numeric and analytical representations Capture and track the values of a graph and collected data, and observe number patterns. Organize the results of statistical analysis. Experience capabilities similar to using computer spreadsheets: label columns, insert formulas into cells, select individual cells and change their size, and more. • NOTES supporting written representations Put the math in writing. Include the word problem with its solutions. Explain problem-solving approaches - right in the handheld or computer software. Question-and-answer templates allow educators to prompt students to document their steps and progress. • http://www.ti-nspire.com/tools/nspire/features/multi_rep.html Linking Representations • With TI-Nspire™ and TI-Nspire CAS technology, the multiple representations of a problem can be dynamically linked together. This means that changes to one representation are instantly reflected in other “linked” representations of the same problem – on the same screen. • Educators and their students can explore more of a problem– in algebraic, graphical, geometric, numeric and written forms – without having to switch back-and-forth between screens. Explore individual representations, one at a time, or as many as four all on the same screen. • The dynamic linking of multiple representations provides real- time, interactive feedback so students can try different problem- solving techniques and compare predictions to outcomes. Data and Statistics • This built-in application allows educators to input and organize statistical data, using different graphical representations on a single screen to guide students in hypothesizing results and making meaningful connections. • Summarize statistical data using different graphical methods. • Experience list and spreadsheet features similar to computer software features. • Manipulate and explore data - watch how dynamic changes in data changes can affect the statistical analysis. • Create "quick graphs" of one-variable and two-variable data sets. • Perform a variety of descriptive and inferential statistical calculations on real data sets, while simultaneously analyzing graphical representations Additional Data and Statistics Functionality: Scatter plots x-y line Histogram Box plots Regression lines Normal probability plots Hypothesis test plots http://www.ti-nspire.com/tools/nspire/features/data_stats.html Grab-and-Move • Grab-and-Move Make changes, observe relationships and try new approaches. “Grab-and-move” the various properties of a graphed function, as well as the dimensions of a graph itself, to discover mathematical relationships and patterns. • “Grab” a line, parabola or graph, for example, and “move” it to see the effect of changes, in real time. As a result, the corresponding equations of each function will update automatically through the dynamic linking feature, which is effective for identifying patterns key to conceptual learning. Such interactive feedback can help students explore insightful “what if” scenarios. • Grab-and-move the x-axis, y-axis and tick marks of a graph. Alter plotted points, lines, curves and geometric constructions. In the example below, the curve of a graphed function widens as the x-axis is moved out. When the x-axis is moved in, the curve narrows. http://www.ti-nspire.com/tools/nspire/features/grab_move.html Save and Review Work • Save and Review Work Follow every problem-solving step by every student. • The unique features of TI-Nspire™ technology include the ability to create, edit, save and review problem solving in electronic documents similar to the word processing and file storage features of a computer. • The ability to save and review assignments as electronic documents allows students to show their work step-by-step and demonstrate problem-solving techniques. Educators are able to effectively assess critical thinking and guide individual progress. • Class assignments and homework documents can be saved on TI-Nspire/TI-Nspire CAS handhelds and computer software. Students are able to pick up where they left off in a previous class. Students can continue work on projects outside of class, easily transferring documents between their handheld and computer. TEACHING WITH TI-NSPIRE DOCUMENTS • TI-Nspire and TI-Nspire CAS technology’s use of documents aligns with teaching practices proven to enhance learning. • Save and continue work from one class to the next Allow students to reflect on their work and make revisions. Organize the build-up and sequencing of ideas Conduct formative assessment of student understanding Prepare and save activities and other materials before class. http://www.ti-nspire.com/tools/nspire/features/save_review.html Press-to-Test • With the built-in Press-to-Test feature on TI-Nspire™ and TI- Nspire CAS handhelds, you can stop potential cheating by temporarily disabling all current documents and denying access to programming libraries. A blinking LED located at the top of the TI-Nspire handheld provides proctors a way to quickly and confidently see that a student's handheld is operating in Press- to-Test mode. After the exam, handhelds are easily restored for classroom use by exiting Press-to-Test mode, and all previously created documents restored. • The new Press-to-Test feature is only available with TI-Nspire operating system version 1.3 or higher. http://www.ti-nspire.com/tools/nspire/features/press_to_test.html TI-84 Plus Compatibility • The TI-Nspire™ handheld comes with the interchangeable TI-84 Plus Keypad* that provides side-by-side compatibility with the TI-83 Plus and TI-84 Plus families of graphing calculators. • By inserting the TI-84 Plus Keypad, educators and students can continue using the TI-Nspire handheld alongside TI-83 Plus, TI- 84 Plus and TI-84 Plus Silver Edition graphing calculator models. Simply remove the TI-Nspire Keypad and slide in the TI-84 Plus Keypad. It's fast and easy, and fits securely into place.
