The Uncertainty of Grades in Physics Courses is Surprisingly Large
نویسنده
چکیده
Almost all teachers are required to submit final grades for their students. In this note we discuss the uncertainty in those grades with an emphasis on grades in physics courses. We will estimate that the statistical uncertainty in final grades is at least 4% out of 100%, and is probably significantly higher than this. The implications of this result on things like calculating Grade Point Averages are large.

Introduction: GATE (Geant4 Application for Tomographic Emission) is a Monte Carlo simulation platform developed by the OpenGATE collaboration since 2001 and first publicly released in 2004. In Geant4, each physics process is described by a model (several models are sometimes available for a given physics process) and a corresponding cross-section table. All Geant4 physics model...
متن کاملComparison of Attitude toward Attendance in Class Sessions and Grades of Courses for Students with and Without Absence
Introduction: The most important setting for teaching, specifically for difficult scientific topics, is classroom. Due to the uncertain results of previous investigations which are limited in number too, this study was implemented to compare attitude toward attendance in sessions and grades of associated courses for students with or without absence. Methods: In this descriptive longitudinal st...

The issue of talent-discovering is one of the most important issues in the field of education and research that has always been a concern for educational systems. Studying the issues of identifying and guiding talented students can illuminate a large part of the activities of the executors and practitioners in order to accomplish their mission effectively. On the other hand, quantum physics has...
