The purpose of this assessment probe is to elicit ideas about uniform motion. The probe is designed as a starting point to encourage students to use evidence and observation to support their ideas. The goal is for students to eventually develop and then test an operational understanding of the concept of speed. This free selection includes the Table of Contents, Foreword, Preface, Acknowledgments, About the Authors, Introduction, and the Index.

While the answer may seem obvious, many students lack in experiences and will need to actually do the experiment described to understand what the question is asking. Since this introduces fundamental ideas like constant speed and eventually friction, I would recommend this probe for students as a way to lead into discussions of measuring motion and refer back to it when discussing the directional component of forces.

This probe is designed to help students develop a concept of speed. My students did not do well on this probe initially. My instruction added some help, but I did not do a good job. I plan to review the accessory materials (background an implementation) to imporve my instruction next year.
