Encouraging students to understand the 1D wave equation

|
By Muhammad Aswin Rangkuti, Universitas Negeri Medan, Ricardo Martinez Karam
| Physical Review B
Despite its crucial importance in physics, there are not many studies focusing on student difficulties and teaching strategies related to the (1D) wave equation in the PER literature. In order to contribute to fill this gap, we conducted a study with university students which focused on specific aspects that are crucial for understanding this equation.

Conceptual challenges with the graphical representation of the propagation of a pulse in a string

|
By Universitas Negeri Medan, Ricardo Martinez Karam, Muhammad Aswin Rangkuti
| Physical Review B
Abstract Student difficulties with making sense of graphs in physics have been thoroughly reported. In the study of one-dimensional waves, the issue is even trickier since the amplitude is a function of two variables (position and time). In this work, we investigate students’ reasoning and difficulties with interpreting the graphical representation of the propagation of a pulse in a string.
