Physics education research (PER) has resulted in new materials, approaches to teaching, and theoretical understanding of student learning in physics. PER has influenced practices in introductory physics courses, impacting tens of thousands of students, and a growing number of current and future teachers. While the field has demonstrated positive effects in many instances, remarkably little work has gone into understanding how research-based, educational reforms are replicated and sustained. This talk will begin by discussing the curricular choices we have made at CU Boulder, and why. | 10

The effective modeling of electromagnetic waves on unbounded domains by numerical techniques, such as the finite difference or the finite element method, is dependent on the particular absorbing boundary condition used to truncate the computational domain. In 1994, J. P. Berenger created the perfectly matched layer (PML) technique for the reflection-less absorption of electromagnetic waves in the time domain. The PML is an absorbing layer that is placed around the computational domain of interest in order to attenuate outgoing radiation. | 12
