20 educators attended the afternoon “Introduction to Modeling” workshop lead by Lee Trampleasure and Jon Rockman. Educators were lead through the development of one of the Modeling “paradigm labs.” The lab used constant velocity cars to develop position vs time data that could be graphed to determine the average velocity of the cars. After groups graphed their data, they created whiteboard presentations of their results. After a discussion of the results, Lee presented data from his classes this year, showing the results of 20 student groups. For more information on Modeling Instruction, visit modeling.asu.edu.

This post includes a summary of our Fall meeting (it is being expanded during this week). You can download and print a certificate of participation here. Share and Tell presentations. Keynote: Blinky Lights Modeling Instruction introduction workshop Meeting announcement/description.
At every section meeting one of our most popular portions is the Share n Tell during which participants have five minutes to share a demo, idea, concept, book, problem, example, etc. Talkative participants must fear the dreaded gong at the end of five minutes. Below please find notes and relevant links from the special double session of Share n Tell from our Fall NCNAAPT Section Meeting and mini-conference: Don Payne, Carondelet High School A Piezo Electric popper (spark fed) has been adapted to drive a small toy car. A film canister is filled with either ethanol or Bonaca breath spray.…
