Abstract Title: Conceptual Survey of Electricity and Magnetism: Analysis of the items and recommendations
Abstract: The Conceptual Survey of Electricity and Magnetism (CSEM) is an assessment tool widely used in the Physics Education Research community since its introduction in 2001. Although it's been some since its publication, there is no later study in which the test is evaluated as an assessment tool by analyzing the items in detail. This contribution aims to do that by two analyses: (1) a general statistical tests focusing on the items such as difficulty index, discrimination index, and point biserial coefficient; and (2) a detail analysis of the items' wordings and images. We use data from 500 undergraduate students who were finishing an introductory calculus-based electricity and magnetism course. From our analyses, and taking some general recommendations for designing multiple choice questions from the literature, we identified some problematic items. We present specific recommendations to improve those items. These analyses and recommendations may be useful for researchers using the test as an assessment tool.
