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
