Sharing Nspiration Conference: Modeling Data with the TI-Nspire CAS Fletcher’s Meadow S.S. Saturday, February 27, 2010

Nspire Self-Assessment  Please self assess you experience with Nspire:  1 finger indicates no prior experience  2 fingers indicates only using at workshops  3 fingers indicates using the handheld in your class  4 fingers indicates downloading and using pre-made activities in you class  5 fingers indicates creating your own activities in your class and being an expert at your school

Function Modeling  The Ontario secondary Mathematics curriculum has a function modeling theme that runs from grades 9 to 12  Nspire makes function modeling accessible to every student using only handhelds and CBR2’s  Linear modeling in grade 9  Quadratic modeling in grade 10  Periodic (Sinusoidal) modeling in grade 11  Collecting data improves student engagement and comprehension

Auto Launch Window  Since OS v1.6, Nspire allows “Plug N Play” with data collection devices  To begin you simply open a new document and add a blank notes page  Connect the CBR2, or Vernier probe, and an Auto Launch window appears…

Data Collection Console  Once you select the type of page to collect data onto, a split screen appears with the data collection console at the bottom  The data collection console controls the beginning and end of data collection  To change the frequency and duration of the data collection use the Data menu by pressing b  To switch between the data collection console and the graph press /e  The data collected is stored into variables dc01.time, dc01.dist1, dcc01.vel1 and dc01.acc1

Nspire CAS Teacher Edition Software  This software allows you to demo data collection  You will need a mini- USB adapter  Lets see a demo ….

Data Collection using the CBR2  Now it’s your turn. Form teams of three with a variety of experience levels in your team  Each team uses one handheld, one CBR2 and tools to collect data  You will do three activities in a carousel: Collect and model linear data Collect and model quadratic data Collect and model periodic data  If you need help refer to the data collection handout

Vernier Data Probes for Nspire CAS  Vernier offers four products for data collection EZ-Temp Probe (connects to Handheld and collects real time temperatures), P/N EZ-TMP, $59 Go-Link (connect probes to PC), P/N GO-LINK, $85 Easy Link (connect CBL2 probes to Nspire), P/N EX- LINK, $89 Mini USB Adapter (Connect EZ-Temp or CBR2 to PC), P/N MINI-USB, $7.50  James Frielink x113) from Merlan Scientific is the rep for
