Abstract

For the last four years, the School of Physics at Georgia Tech have been preparing new Graduate Teaching Assistants (GTAs) through a program that integrates pedagogy, physics content, and professional development strategies. Here we discuss various assessments we have used to evaluate the program, among them surveys, GTA self-reporting, and end-of-semester student evaluations. Our results indicate that GTAs who participate in the program find its practical activities useful, feel better prepared for teaching, make use of learner-centered teaching strategies, and receive higher scores in teaching evaluations., Comment: 4 pages, accepted to Physics Education Research Conference Proceedings (PERC 2017)

Abstract

Pendulums have long been used to to determine the kinematics of non-inertial rotating systems. A proper study of this classical mechanical device under the action of a rotating reference frame can fully describe the behavior of such non-inertial systems. In such venue, we have placed a pendulum inside a rotating plane ride in an amusement park, and determined the parameters defining the rotation of the ride by solely analyzing the pendulum's motion. We present two different methodologies to determine the motion patterns of the ride as well as a computer-based reproduction of the trajectory of the pendulum throughout the ride.
