Collecting and Modelling Data with Nspire’sDataQuest App OAME 2011 Conference University of Windsor
Big Ideas in Secondary Math • According to Marian Small’s new book: “Big Ideas from Dr. Small: Grades 9-12” one big idea is Transformations: • By focusing on the “Big Ideas”, teachers will enable and encourage students to use mathematical reasoning throughout their lives • Using technology to investigate transformations of functions is a theme that runs from grade 9 to12
Function Modeling • Nspire makes function modeling accessible to every student using only handhelds and CBR2’s • Linear modeling in grades 9 &10 • Quadratic modeling in grade 10 &11 • Periodic (Sinusoidal) modeling in grade 11 • Collecting data improves student engagement and comprehension
DataQuest App • Version 4 of the Nspire OS features the DataQuest app • You simply open a new document and add a blank notes page • Next, connect the CBR2, or Vernier probe, and the DataQuest app is automatically launched • Refer to Quick Reference handout for details on this app
Linear Data Modeling Demo • The Nspire teacher edition software allows you to model data collection and linear modeling • You will need a mini-USB adapter available from Vernier • Lets see a demo ….
Experiments to Gather Data for Modeling: Linear Data • Walk at a constant rate • Others? Quadratic Data • Ball bounce • Roll a can up a ramp • Pillow toss • Others? • Sinusoidal Data • Pendulum • Walk around • a hula-hoop • Weighted • Springs • Others?
It’s Your Turn … • Form a group of 3 or 4. • Assign roles (Operator, Tech Support, Coach) • Your group will complete both activities: • Modeling Linear Data (Violet sheet) • Modeling Quadratic Data (Green sheet) • For extra support refer to: • Nspire CAS Touchpad Quick Reference (Yellow Sheet) • DataQuest Quick Reference (Blue Sheet) • Manually Manipulating Functions on TI-Nspire (Pink Sheet)
Vernier Data Probes for Nspire • 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 CBL2 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 • Visit the Texas Instruments booth for more information
