From the big bang to black holes, from elementary particles and the fundamental interactions that govern our universe to the world's largest and most complex scientific instruments, our knowledge of the world builds on modern physics. To make our current-best understanding available to all, we need to invest in educational research and bridge the gap between those who know science, those who teach science, and those who learn science. 

This month, we are going to discuss a paper by Paul Alstein, Kim Krijtenburg-Lewerissa & Wouter R. van Joolingen:

This article describes the design and evaluation of a simulation environment for special relativity (SR) education at the secondary level. In recent years, SR has become increasingly popular in secondary school curricula worldwide. Because the key concepts in SR are very remote from everyday experience, they are difficult for students to learn. Computer simulations provide a promising approach to explore these abstract concepts in a simplified and idealized virtual environment. The currently available simulation tools for SR, however, are limited in terms of usability and flexibility. We report on the development of an online simulation environment, named Relativity Lab. In Relativity Lab, students can construct simulations themselves and freely select the inertial frame of reference from which the simulation is rendered. We performed a small-scale evaluation (N = 16) in which Relativity Lab was used in inquiry-learning activities. Results indicate that students found Relativity Lab a helpful tool for visualizing relative motion and relativistic light propagation. Moreover, the inquiry-learning activities helped students to recognize discrepancies between their prediction and the outcome of a simulation. We propose improvements to the current task design by providing stricter instructions with regard to constructing the simulation and switching between inertial frames.
